Before starting review I want to tell all the reader that this review is based on the internet research, I and my team did a lot of research on the internet, google and youtube and then conclude this review, simply means this review is the juice of all the information available on the internet about Samsung galaxy m21.
Samsung Galaxy M21 launched in India on 18 March 2020, it is an average phone, if you are not a heavy user of phones, then Samsung is offering a great package phone for Indian consumers like you.
This phone comes in two variants one is 4GB RAM 64GB storage and other is 6GB RAM and 128GB of storage the main difference between both variants is RAM and storage rest of the things are the same in both variants.
The build quality of the Samsung Galaxy M21 is very low and even the build quality of all Samsung M series phones is low, they spend less on the build quality and manage the cost of production, Samsung has used plastic material and Corning Gorilla Glass 3 protection in Samsung Galaxy M21 to reduce production costs, and also this phone only available in two colors black and blue.
The best thing in Samsung galaxy m21 is its battery and display, galaxy m21 comes with a 6000 mAh battery which is quite spacious in this price range, and the phone comes with AMOLED display, which is quite impressive.
If you use this phone continuously, you will get 10 hours of battery backup, in that 10 hours you can play a PUBG for 2 hours, 2 hours for calling, 2 hours for audio music and 4 hours for internet video, and an average user will get the battery back up of 24 hours and more.
You will see the triple rear camera setup on the Samsung Galaxy m21, the primary camera has 42 MP sensor, and the other two are 8MP and 5MP, the primary camera supports up to 4x digital zoom and comes with f/2.0 aperture, 8MP camera is for wide-angle and ultra-wide angle effect and that comes with f/2.2 aperture, and 5Mp camera is for depth effect and it also comes with f/2.2 aperture, and on the other hand front camera has a 20 MP sensor and comes with f/2.2 aperture.
Both the camera clicks very good pictures on lights, but in the low light performance of the camera is not that much good, on Rear camera, you won’t get video stabilization when shooting video at 4k, but if you shoot video in 1080 pixels you will see a good video stabilization, but it could have been improved, but overall at this price range, I’m satisfied with its camera performance.
Samsung is the best in network connectivity. I did not see any network problem on this phone.
You can play pubg games in Samsung Galaxy M21 on the extreme frame rate and HDR graphics as it supports it. but I recommend you to play on smooth graphics because on HDR you will not get good performance you will see lots of frame drops and lags issue while playing on HDR, after playing pubg for 2 hours phone temperature reach to near 40°c.
If your primary purpose for buying this phone is gaming then this phone is not for you, this is not a gaming phone this phone is a multimedia oriented phone which made for the average users of the phone.
If you are not a heavy user of the phone and thinking to buy this phone for entertainment purposes like music, watching video streams, and some times games then this is the best choice for you, you can go with it.
Samsung galaxy m21 comes with 15W charger and Samsung claims that they offer fast charging in the galaxy m21 but actually it takes longer to charge, you will need more than 2 hours of time to fully charge the phone from 0 to 100, refer below chart to understand galaxy m21 charging time.
