How is AI evolving in Nepal? An in-depth look at the AI Expo Nepal 2019

Nepal’s first and biggest AI Expo happened on August 24th, 2019 at Soaltee Crowne Plaza. AI Expo Nepal 2019, a joint initiation by Fusemachines and Artificial Intelligence for Development (AID) aimed to showcase the best AI projects/papers from academia and industry. More than 2000 people attended the event which came to as a surprise and marked a significant period in history. The expo featured about 20 projects from academia and industries with each project focused on interesting use cases.

The event commenced with a keynote address from Dr. Sameer Maskey, Founder and CEO of Fusemachines where he talked about democratizing AI and officially announced his campaign ‘AI Shikshya for Nepal’ which aims to empower students, AI engineers and researchers all over Nepal. The event followed up with two plenary discussions consisting of panelists and moderators sharing their thoughts on integrating AI and AI for national development which then followed up with an address by Chief Guest Minister of Education, Science, and Technology Giriraj Mani Pokharel and then followed by learning sessions on AI.

The plenary discussions highlighted major concerns, shortcomings, challenges, plans, and policies concerning AI in Nepal. The discussions pointed out a major design flaw in existing systems in the government sector where the systems are fragmented and lack integration among other systems. The discussion also helped shed some light on the need for policies on data and security.

In ‘Learning Sessions’ senior engineers from Fusemachines and AID presented attendees with key concepts on Machine Learning, Deep Learning, Computer Vision and Natural Language Processing. In case anyone missed the event, AI Expo Nepal has listed a range of learning resources where one can teach themselves and sharpen their skills in AI.

The exhibition stalls were the main center of attraction about this expo as it featured some interesting projects and added a new perspective on intelligent systems and its application areas. The 20 projects featured in this expo is actually the condensed version. The selection, elimination, and mentoring projects from idea and prototype to a minimum viable product lasted for about 3 months prior to the main event, the AI Expo. Here I’ll discuss some of the projects featured in the expo based on my interaction with teams:

Attendance with Facial Recognition

This project identifies students in a classroom and takes attendance recognizing their faces via CCTV cameras. The algorithm recognizes faces on certain predefined intervals based on which it sets attendance as present in class. The technology they used for this project is TensorFlow library with machine learning models such as SSD (Single Shot Multibox Detector): used for object detection and FaceNet: used for facial recognition.

For this application to identify faces it needs an image source of students as a dataset and trains the algorithm based on the classified data. As the number of students will vary, the data collection and training of the algorithm might take a significant amount of time. Also, the quality of the CCTV camera plays a vital role in the performance of the algorithm to correctly identify faces, the same with the latency due to internet speed. Based on their demo footage, their application detected facial geometry but not the person in the face, upon which they added the feature could be integrated in the future.

Prevention Road Kill

The main purpose of this project is to detect objects and track lane in a highway and prevent a car from a collision. This project makes use of deep learning algorithm such as Convolutional Neural Networks (ConvNet/CNN) to detect objects from video frames and prevent collision.

The limiting factor for this project is it requires a lot of training data and based on their presentation it seemed the project needed a lot of work to be done.

Savior of the Heart

This project is a desktop application that takes various input parameters from the user and predicts their risk score of having any heart-related diseases within a 10 years’ time interval along with health status of the heart with prevention measures based on their status. This project uses a machine learning model such as Random Forest Regression and SVM Regression.

As promising this project sounds, this could be a good fit for clinical labs and hospitals as they have a wide range of data from patients. As this application deals with critical data, the result it predicts is critical too. If this results in too many false positives then this could have a major impact on the patient’s psychology. This concern was acknowledged by the team and they stressed the fact that for this application to perform well it needs to be trained on health data from Nepal.

Essay Grader

This application auto grades human written essays based on the number of datasets, i.e. a wide variety of essays it’s trained with. The project is based on Natural Language Processing (NLP), a subfield of AI concerned with interactions between computers and human languages.

According to the team, this model can help grade essays in standardized tests like IELTS writing test and GRE. Moreover, it can also be used to grade essay written by students in school which could save a lot of time for teachers. There are some limitations though, the model is not well trained as it lacks actual academic datasets and the results might be biased, in case, if the sample assays for training were marked inconsistently. They acknowledged the model is not perfectly ready to score essay better than humans but it does give a sense where the essay score stands in a range of 0 to 12.

Music Generation with Nepali music

This project aimed to generate polyphonic music from a model trained on Nepali music. The model was based on Long Short-Term Memory (LSTM); a Recurrent Neural Network (RNN) architecture.

The primary objectives are:
– Inspiration for aspiring composers.
– No Copyright Music for use in YouTube videos.

The team explained they learned about music theory, explored restricted Boltzmann machines, LSTM based networks, simple Markov models and experimented with LSTM model with attention for polyphonic music generation.

Based on their demo, the application was able to generate music but the melody was just a random one based on a diatonic scale that lacked motif and context. Overall, it was a decent effort.

Real-Time Vehicle Tracking and Recognition (RTVTR)

This prototype was developed by Inspiring Lab Pvt. Ltd., an AI startup. RTVTR is a computer vision application that recognizes characters in Nepali number plates. Initially, an image frame is captured from a CCTV camera and passed through a prediction model to extract the region from the frame consisting of a license plate. This plate image is then passed through an Optical Character Recognition (OCR) model for prediction of Nepali characters. Additional features include recognition of different types of vehicles, vehicle count, flagging and identifying specified vehicles and detection analytics.

According to the team, the purpose of developing this system was aimed towards solving traffic congestion and surveillance, parking system and time card management, as well as toll booth collection problems prevalent in the urban landscape of Nepal.

Winners of the AI Expo Nepal 2019

Based on the selection criteria, out of 20 projects, three winning projects were selected:

  • Real-Time Vehicle Tracking and Recognition (RTVTR)
  • GhumGham
  • Polyphonic Music Generation with RNN

The event ended with closing remarks by Mr. Kshitiz Rimal, Head of Research at AID, and Photo Session.

Conclusion

This expo proved that there are AI talents here among us waiting for the opportunity to showcase their skills. The participating teams also highlighted a major limitation which hindered their projects due to lack of availability of local datasets, as a result, they had to rely on sample datasets from the internet. As AI is built on top of data, the more data is fed to the algorithm, the better the performance. Also, the overwhelming number of 2000+ attendees showed that people are interested in AI and want to learn more about it and embrace change. The plenary discussions showed that government needs to step up and embrace change as well and integrate their available infrastructure with modern technology, scalable architecture and artificial intelligence.

Samsung Galaxy A90 5G goes official: A midrange phone with flagship specs

Samsung launched a vast number of smartphones this year. And that happened mostly in the midrange segment. With its M-series and A-series smartphones, the South Korean tech giant populated every small corner of the midrange and budget segment. Despite having over a dozen of smartphones in that segment before the end of Q3, the smartphone maker isn’t done yet. Samsung yet again launched a new premium midrange device expanding its A-series lineup. But unlike all the previous A-series devices, the recently-launched Samsung Galaxy A90 5G comes with a flagship chipset and a 5G connectivity.

Overview:

The most striking thing on the phone is its capability for the 5G connectivity. And that’s what set the A90 5G apart from its A-series siblings. The Galaxy A90 5G also happens to be the fourth smartphone in Samsung’s lineup to have the 5G modem on the board.

To unleash its 5G capability, Samsung also had to include the flagship-tier Snapdragon 855 processor. To complement the performance, 6/8GB RAM has been provided. Talking about the storage, the phone comes only with the 128GB storage. And it’s quite strange that there is an SD card slot only on the 6GB RAM variant.

While looking at other specs of the phone, the Samsung Galaxy A90 5G highly resembles with the Galaxy A70. The Galaxy A90 5G features a 6.7-inch Super AMOLED Display with a U-shaped notch on the top.

The infinity-U display on the device gets Full-HD+ resolution in the weird 20:9 aspect ratio. And like all the Samsung’s premium mid-rangers out there, A90 5G also comes with an in-display fingerprint scanner. Although the type of fingerprint scanner is yet kept a secret, it is probably an optical one like that on the Galaxy A50 and A80.

As for the cameras, the phone flaunts a triple camera setup on the back, which seems like a norm in 2019. The camera module embraces a 48MP main camera, an 8MP ultra-wide-angle lens, and a 5MP depth sensor. Similarly, on the selfie front, there is a 32MP snapper tucked neatly inside the notch. The A90 5G also comes with built-in features like Super Steady, Scene Optimizer and Flaw Detector for the rear cameras, where the front one boasts a Live Focus Mode.

Samsung has tried to generously provide top-grade features on the device. And in that context, the South Korean smartphone maker has added Samsung DeX support. And that made the A90 5G the first one to feature that impressive feature on the A-series family. Furthermore, there is a sizable 4500mAh battery with 25-watt fast charging support.

Vivo Y12 with Triple rear camera, 5000mAh battery launched in Nepal

Vivo has launched a new mid-range phone, the Vivo Y12 in Nepal. It is among the first device to flaunts a triple camera setup at this price range. But a lot of things have changed in 2020 and the smartphone market has been competitive more than it has ever been. So can Vivo Y12 compete against the new contenders in the market? Let’s learn more about the phone.

Vivo Y12 Overview

Design

The Vivo Y12 features a large 6.35″ IPS Halo Full View display with a tear-drop notch. The screen here comes with HD+ resolution, just like on the Y17. Even in terms of design and looks, it again highly resembles with the Y17. The screen is large but the limitation is its HD+ resolution. The company has not revealed any kind of Gorilla glass protection.

Camera

One of the exciting things about this phone is a triple camera setup for the budget price. The triple camera setup comprises of a 13 MP lens, an 8 MP ultrawide and a 2 MP depth sensor. Of course, even with triple lenses, we can’t expect very high results with a phone of this price range. Also, it’s selfie camera is an 8 MP shooter with AI support.

Performance and Memory

Furthermore, the phone runs on the modest Helio P22 chipset, and there are two memory options available – 3 / 32 GB and 4 / 64 GB. The version that’s launching in Nepal has 3GB of RAM and 64GB of storage with a dedicated microSD card slot.

Battery and others

And another nice feature about this phone is its 5000 mAh battery, which, with its specs should last more than 2 days easily. Charging is done via micro-USB and there’s no fast charging as well.  In addition, there’s also a rear-mounted fingerprint sensor. On the software front, it runs on Android 9.0 Pie with VIVO’s custom UI FunTouch OS 9.0. Color Option includes Burgundy Red and Aqua Blue.

Teaser released for the Vivo Nex 3; sports a waterfall display

New teasers have started flowing in for the latest Vivo flagship. Labeled as the Vivo Nex 3, the device will probably launch sometime next month. But what’s the hype about this device you say? Well, for starters, the device sports the worlds first waterfall display.

Vivo Nex 3 Overview:

The waterfall display is basically a fancy term for a device with edge screen. Galaxy Edge devices have implemented such a screen for a long time. However, in a video, the popular Youtuber Mrwhosetheboss claims that the edged display is more in this device. In Nex 3 it is almost 45% more than devices that are already available. Now, that’s huge!

In the video, we can see that the device does not have any notch. So, sticking to the on-going trend, the device must have a motorized pop-up front camera. Furthermore, as one would expect from a Nex device, the bezels are all thinned out. And as mentioned before, the display is extremely curved. This thereby gives the device its prized “waterfall” effect.

Aside from its huge display, the phone does not have any physical buttons either. Their replacement? Capacitive buttons. These capacitive buttons have haptic feedback. No need for buttons. Pressing on the capacitive buttons supposedly gives one the feel of pressing an actual button. The haptic feedback in the specified place analyses your fingers motion when placed over them. And then perform the necessary task. However, there is a small power button on the top rim of the phone.

vivo nex 3 waterfall display

No particular details about the phone were disclosed in the teaser video by Mrwhosetheboss. However, he did test the devices 5G capabilities, camera, and its general performance. 5G as many of us no is really fast. And the Nex 3 has it. Furthermore, as the device has a waterfall display, anything you capture will seamlessly fit into your screen. Nevertheless, the camera details are not mentioned at all.

From the teaser, the device looks exciting to me. But the waterfall display comes with its own set of disadvantages too. Huge edge display probably means a lot of accidental touches. But we cannot say anything with certainty right, now can we? We’ll have to wait until the device officially launches before giving the final verdict.

OPPO launches three Reno smartphones- Reno 2, Reno 2Z and Reno 2F!

Chinese smartphone manufacturer OPPO has unveiled three variants of the OPPO Reno in India. The phones are named OPPO Reno 2, OPPO Reno 2Z and OPPO Reno 2F. The Reno 2 has the highest of the specs among the three followed by Reno 2Z and Reno 2F. The three phones differ mostly in terms of display size, processors and camera modules.

First, let’s look at what’s similar in all three phones. All three of them come with 8 GB of DDR4X RAM. The Reno 2 and Reno 2Z comes with 256 GB memory respectively while the 2F has 128 GB storage. All three devices flaunt an ultra-fast UFS 2.1 storage. So you are gonna get better read/write speeds with these devices. All the phones also come with quad-camera setup at the back. But, these differ in the configuration and the sensor type.

None of the three have a notch for the selfie camera as all of them feature motorized pop-up selfie cameras. The OPPO Reno 2 has a shark fin-like selfie camera following the legacy of its predecessor while the other two, the Reno 2Z and Reno 2F have a centrally- faced pop-up selfie camera.

Likewise, the trio features Android 9 Pie out of the box with ColorOS 6 on top. All are backed by 4,000 mAh batteries and support 20-watt VOOC 3.0 Flash Charge technology.

But like mentioned earlier, there are slight differences between the three in terms of camera specs. The Reno 2 comes with optically and electronically stabilized 48MP Sony IMX586 sensor, a 13 MP telephoto lens (that supports up to 5x Hybrid Zoom), an 8 MP ultra-wide-angle camera and a 2MP Monochrome sensor for capturing depth information.

Cam Scanner removed from Play Store: Found infected with Malware

Nothing is 100% safe anymore. Researchers have found a Trojan-Dropper malicious virus hidden inside Cam scanner, an Android app with more than 100 million downloads on Google Play Store! The malware was found by two Kaspersky security researchers, Igor Golovin, and Anton Kiva. The app was following a series of negative reviews for the last few months and while researching for the cause, the team of two found the faulty virus.

Cam scanner is a free app on the Google Play store that turns an Android mobile device into a portable scanner. It scans and manages documents, receipts, bills, business cards, certificates and so on.

Cam scanner app infected with Trojan virus

The intrusive module so identified in Cam scanner is a Trojan virus called Trojan-Dropper.  It can extract and run a second malicious component accommodated within the app. This can be leveraged to infect people’s devices with other kinds of malware.

What happens when you download and run the Cam Scanner app is, the dropper decrypts and executes malicious code contained in a “mutter zip” file present inside of the app before downloading encrypted code from the control server.

trojan virus in Camscanner

The virus functions to download and launch a payload from other malicious servers, hence infecting your device. As a result, the owners of the malicious module can use an infected device to their benefit by showing the victim unwanted advertisements and maybe even stealing money from their mobile accounts by charging paid subscriptions.

But thankfully, the virus did not reside in the code of Cam Scanner app itself, instead, it’s part of a 3rd party advertising library that was recently included in the app.

After discovering such intrusive activities, the researchers promptly reported the findings to Google, who then removed the app from its Play Store. Similarly, the app developers have reportedly gotten rid of the virus and with the latest update of Cam Scanner. However, if you are running the previous version of the app, the virus might still be contained in the app, say the researchers.

But, if anyone is using the paid version of the app which does not include 3rd party advertising, then those people are safe from the infectious module as reported by the developers.

So, the conclusion that can be drawn from this is that any app, even if it is from the most trusted store, even the ones with trusted reviews can turn into malware overnight. So, your safety is in your hands. Everybody is strongly advised to always keep a good antivirus app on your Android device to detect and block such malicious activities before they can infect your device.

Also, one should keep a check for the latest reviews of the app and verify app permissions before installing any application.

It’s been a long time since we have seen anything new from Lava in the market. However, with the launch of its new device, the Lava Iris 43, it is planning on making its comeback. Primarily focused on the budget segment, this device will certainly face a tough competition. But is it capable of doing so? Let’s have a look at its features and decide for ourselves.

Overview:

The device has a 5.0” screen that comes with a resolution of 480 x 854 pixels. It runs on Android 8.1 Oreo Go and uses the Spreadtrum SC7731 processor. The processor is clocked at 1.30GHz and has 4 cores. In addition, an ARM Mali-400 MP2 GPU is also included in the chipset. It has 1 GB RAM and 16GB internal memory on board. However, the memory can be expanded up to 64GB through a dedicated microSD slot.

Talking about the camera, it comes with a 5MP rear camera and 2MP front camera. The battery on this device is of 2000mAh. Considering the features in this device, the battery should actually be great. Also, this device comes with a Smart Face Unlock. Now, that’s interesting considering the device has been launched at a price of Rs. 5, 899.

Now considering the fact that the device is targeted for the lower-budget segment, the device certainly has a lot to provide. Furthermore, the addition of a Face Detector gives a nice touch to it. However, with better devices available from other brands for just two or three thousands more, attracting customers will certainly be a tough task for the company.

Vivo S1 Review: A Killer Midrange from Vivo, Finally!

Vivo seems to have finally realized what it had been doing wrong all this time. Just roll back few months, they used to launch the Y-series which are overpriced and underpowered in many ways. So, the outcome is well, the Vivo Z1 pro and the Vivo S1.  The Vivo S1 (Rs. 34,690) is slightly pricier than the Z1 Pro and is competing against the likes of OPPO F11 and the Galaxy M40. And looking at the specs, the Vivo S1 looks impressive, but is it any better than the competition? Let’s find out in our Vivo S1 review.

  • Display: 6.53″ (1080 x 2340 pixels) SuperAMOLED
  • Rear Camera: Triple, 16 MP (f/1.78) primary + 8 MP (f/2.2) ultrawide + 5 MP depth sensor (f/2.4)
  • Front Camera: 32 MP (f/2.0)
  • Processor: MediaTek Helio P65
  • CPU: Octa-core (2×2.0 GHz Cortex-A75 & 6×1.7 GHz Cortex-A55)
  • RAM: 6 GB
  • Storage: 128 GB onboard, expandable up to 256 GB
  • OS: Android 9.0 Pie, FunTouch OS 9
  • Battery: 4500 mAh, 18W Fast Charging
  • Sensors: UD Fingerprint, accelerometer, gyro, proximity, compass
  • Price in Nepal: Rs.34,690

Display

Okay, first thing, let’s get done with the display. It does not have a punch-hole display like the Galaxy M40 but the notch here is so tiny, it’s barely obtrusive. The bezels too are very less, overall the display looks clean.

It’s a 6.3 inches Super AMOLED screen so you can imagine how it is. The colors on it look vibrant and the blacks look dark making for very good display experience. And side by side with the IPS panel of the competitions, the display on it is far better.

And this AMOLED screen is a house for an in-display fingerprint sensor too which unlocks fast but don’t expect anything of OnePlus 7 Pro (Read review) kind. The sensor, I would say is fairly accurate, but I have had instances where it has not read my fingerprint altogether. But that has only happened a few times. So no worries!

You also get a dark mode that helps save your battery and protect your eyes, so that’s a handy feature to have. You have different modes from where you can choose the screen color and make it bright or slightly warmer and such. It’s totally up to your preference.

The display indoors is bright obviously but even outdoors, it’s moderately bright. There’s an Always-on display feature too, which makes sense on this AMOLED panel. Apart from your usual date, time and battery percentage, you can get a messenger badge if you get messages and such as well.

Overall, I have liked the display experience on this one. But, moving on to the back, things don’t look that great.

Design

The Vivo S1 has a plastic back and the sides are plastic too. So, durability could be a concern in a long run. But the design is nothing to complain. It’s appealing, feels good to hold and will not disappoint you.

However, smudges are something that is inevitable and I am not someone who likes casing up their phones, so I’ve had a tough time. But usually, people case their phone up so it should not be a huge problem for most.

More about the design, you have these diamond-shaped patterns at the back which looks very unique and I think will appeal to most people. The vertical camera array at the back has this golden lining surrounding it which kind of make the cameras stand out in the overall design.

You get the power and volume buttons on the right and an AI button on the left. It can be used to trigger Google assistant or google search whatever you so prefer. On pressing it twice, however, you can trigger either Google search, google assistant or image recognizer. While I don’t use it that much, it can come in handy sometimes. Although, I wish the buttons could be more tactile. It’s plastic and you will know it right away.

Down below, you get the same old Micro USB like in most of Vivo smartphones, a single firing bottom speaker and a headphone jack.

The output from the headphone jack and the mono speaker is nothing to well write home about. It’s pretty average like what you get with other midrange phones. So, overall, the build is plastic, but the design I think is good enough, it looks good, so I am okay with it.

Performance

In terms of performance, the Vivo S1 has the new MediaTek Helio P65 chipset. It does offer improvements in the CPU performance compared to last-gen Helio P60 and P70, but strangely, the GPU performance has been down-graded. This one uses the Mali G52 GPU while the P60 and P70 use a much powerful Mali G72. Strangely, the chipset does not support UFS storage but has Bluetooth 5.0 support.

And as a matter of fact, we know we get phones with Snapdragon 712 and Snapdragon 675 in this price range whose performance is, well, better than the Helio P65. But, the real-life performance has been good I must say. Day to day tasks run as they should.

  • AnTuTu v7: 146,499
    • CPU: 62875, GPU: 31572, UX: 41769, Memory: 10283
  • AndroBench:
    • Sequential Read: 303.55 MB/s
    • Sequential Write: 189.27 MB/s
  • Geekbench 4
    • Single-core: 1850, Multi-core: 6047
    • RenderScript Score: 4741
  • PC Mark
    • Work 2.0: 6858
  • 3D Mark
    • Slighshot Extreme OpenGL ES 3.1: 1097
    • Slighshot Extreme Vulkan: 1098

I have never faced a single problem in my everyday usage. It has taken up the most intensive of the tasks very well, so I will not complain. PUBG runs in HD in High settings with some stutters here and there. But I preferred medium settings as it gave me smoother performance.

While we are talking about PUBG, Vivo seems to be really focused on giving their users the best experience. If you have watched my Z1 Pro review, I had mentioned that there are several features like being able to reply to texts on the screen while playing games, being able to run the game in the background while it loads and reminds you with a timer, etc.

The phone also has this exercise where it trains you with the help of sounds so that you can better locate your enemy. Some of these features are PUBG exclusive wholesome are for other games too.

But again, if the choice of chipset would have been better, I would have loved the device more. Take gaming for example. Not that there is a problem while playing PUBG or other high-end games, but it would run much smoother with Snapdragon 712 and Snapdragon 675.

Talking about the memory, you get of 6 GB DDR4X RAM and 128 GB of EMMC storage which you can expand up to 256 GB via a dedicated slot.

Software and UI

The phone comes with the latest Android 9 Pie with its own Funtouch OS 9 on top. I used the Vivo Z1 pro read the review of it, you would know how not so fun Funtouch OS is for me.

But, if you are a Vivo user, you should have no difficulty using it. It has this upward swiping toggle menu which I had the most difficulty getting used to initially. Also, the arrangement of things in UI could be implemented better.

Since the display is AMOLED, I have applied this dark mode which has made the entire theme dark which looks good normally but it’s kind of weird on WhatsApp and Instagram.

Talking about the software-based Facial unlock, it’s fast like all Vivo phones and the in-display fingerprint sensor is also swift and mostly accurate. So, this was my primary security unlock option.

Cameras

The S1 comes with a triple camera setup at the back. The primary is a 16 MP f/1.8 lens, the secondary is an 8 MP f/2.2 ultra-wide-angle lens and the third is a 2 MP f/2.4 depth sensor.

Vivo S1 back camera review

And let me tell you one thing, although the camera setup of the S1 looks similar to that of the VIVO Z1 Pro, it isn’t. From colors to details, the S1 captures better photos. The S1 also has slightly more saturation in pictures but that looks good when compared to undersaturated images from the Z1 pro.

On to the wide-angle images, they are equally impressive. The colors look good the same as the primary lens though if you compare the details, you will find the primary lens doing a better job.

For portraits, you get two options, one is portrait lighting and other is aperture mode. In the aperture mode, you can change the blur and focus after taking pictures while in the portrait mode you cannot. And talking about the portrait images, well, they look slightly saturated. The color tones in the skin looks somewhat unnatural. And the edge detection is not very proper either.

But the good thing is, you can choose from various different types of background blur which is fun sometimes.

 

Selfies from the 32MP camera look good. They have a good balance of colors and maintain exposure levels very well. But I have to say again, the skin tone is not very natural. Talking of skin tones, there is AI beauty option which basically makes you look prettier.

Again, comparing the selfies of the Z1 Pro and S1, it shares the same story as the rear camera. The S1 clicks pictures with the richer color tone, making it look better than the Z1 Pro.

There is also something called Fun videos in the cameras which are basically like what we get on Instagram. But the quality is far better than on Instagram. You get a lot of filters to choose from. Plus, it can be fun sometimes when you are in a mood to play around.

You have a portrait feature for selfies as well. You get tones of options for background blurring which is a feature not so useful but still nice to have. Edge detection is a slight problem as the blur is purely software. Otherwise, it does a good enough job.

Talking about night time images, there is no night mode feature here, which is strange, because even all the midrange phones have one. So, maybe that will arrive with a software update. And standard night time images are well, grainy and muddy and lacks maintenance of exposure.

 

As for videos, I was disappointed to not see a 4K option. There’s only 1080p, 720p and 480p. And its video recording capabilities are not so good I have to say. Videos in 1080p look wobbly, they are not stabilized. 720p videos are better stabilized than the 1080p option. But, overall this is not your ideal video camera as I have found on my tests.

Battery

The Vivo S1 comes with a sizeable 4,500 mAh battery whose endurance has impressed me a lot. You can get over a day on normal usage. Plus, you can use various battery saver modes to increase endurance further.

And, I am a pretty heavy user and if the battery lasted me for some time over a day, then a normal or moderate user can expect their battery to last even longer.

You get a Fast charger inside the box with the Vivo S1. It’s an 18-watt charger that can take your battery from 0-100% in around two hours.

Conclusion

So, what do I think about the Vivo S1? Well, before I started reviewing this, I used the cheaper Vivo Z1 pro and as expected, the Vivo S1 is a better phone. This one comes with better features like an AMOLED display, better cameras, an in-display fingerprint scanner, and a better design. So, in many ways, this one is a slightly upgraded version of the Z1 pro, except for the performance; that was better on the Z1 pro.

But Should you buy the Vivo S1? It depends on where you live! If you are from Nepal, Bangladesh, Pakistan or Philippines, where the S1 is available, it’s a good offering for some Rs. 34,690 (US$300).

However, if you are from India, you have the option to get the Realme X, which I personally think is a way better option. The only thing that’s missing with the Realme X is the wide-angle lens, which the VIVO S1 has, but apart from that, the Realme X is better in almost every aspect.

VIVO S1: Pros and Cons

Pros:

  • Good Design
  • AMOLED display
  • Enduring Battery
  • Great Cameras

Cons:

  • Touch Wiz UI
  • Plastic Body
  • Still uses MicroUSB port
  • The chipset could have been better
