Samsung's Galaxy M series was introduced as an online-exclusive lineup to compete with Chinese manufacturers such as Xiaomi and Realme. The devices introduced as a part of this series have gained a lot of popularity thanks to their aggressive pricing compared to Samsung's other offerings. Thanks to their popularity, these smartphones are now also available offline. Samsung recently added another model to this series, called the Galaxy M21. This new smartphone shares a lot of hardware with some of its predecessors but can it stand out? We put the Galaxy M21 to the test to find out.

Samsung Galaxy M21 Summary

The Samsung Galaxy is yet another smartphone to join the Galaxy M series. It brings some of the key features that the Galaxy M series is known for. The smartphone packs in a 6.4-inch AMOLED display that isn’t very common at this price point. It has a vivid output and very good viewing angles. Samsung has made the Galaxy M21 out of plastic to keep the price of the smartphone in the affordable segment. The highlight of the Galaxy M21 is the massive 6,000mAh battery that helps it deliver great battery life. One downside is that the charging time is longer which could get annoying.

Powering the smartphone is an Exynos 9611 SoC that is capable of delivering decent performance. It is available in 4GB and 6GB RAM variants. It also comes in 64GB and 128GB storage variants. The Galaxy M21 sports a triple camera setup with the highlight being the 48-megapixel primary scanner. The camera clicks good photos during the day but low-light camera performance takes a hit. Video performance is below average. Overall camera performance is below average compared to the other phones at this price.

    Rahul Lamgaria (Aug 5, 2020) on Gadgets 360 Recommends
    Review after 30 Day.. Samsung M21 (Midnight Blue, 6gb ram, 128gb memory) 1. Battery :- 5/5 Two day battery standby for normal easy 2.Display:- 4.99/5 Super amaload with full hd.. Superb Display 3.Design:3/5 It has a6000Mah battery, still looking not bulky. No glass body, but who cares after you put a back cover.. In my opinion, don't spend more money for glass body if you uses back covers 4. Camera: 3/5 Back camera pretty good but front camera's low light output is very low.. many features available such as slow and super slow videos available.. 5. OS&UI:- 5/5 Android 10 with One UI 6.Finger print reader and face lock 3.5/5 Face lock and finger print reader are not so fast 7.Processor and performance 4/5 Exynos 9611 is not meant for PUBG gamers .. But for me its perfect as I am not a heavy gamer.. No lag ang hang till now.. but processor is outdated.. 8. Charging :2.5/5. No fast charging.. Provided with a 15W charger and iy takes about 3 Hrs to fully reacharge the phone 9. Accessories : 2/5 No earphone, No Back cover, No Screenguard.. So order backcover and tempered glass when you placing order as its backbody is plastic amd more prone to scratches.. Verdict: For this price Its the best choice for a non gamer ...

  • Poor Amazon Delivery
    R Singh (May 24, 2020) on Gadgets 360 Recommends
    Amazon Mobile Delivery is Pathetic. What takes 2 days to deliver by Flipkart, becomes a week+ from Amazon. Written to Samsung to make sure all mobiles are available on all platforms.

  • Samsung M21 review
    Rahul Lamgaria (Aug 5, 2020) on Gadgets 360 Recommends
    I bought Samsung M21 in Midnight blue variant with 6 Gb ram and 128 Gb internal memory extendable upto 512 Gb using external sd card. Battery works for atmost 1 day with extensive net surfing of 4-5 hours along with 9- 10 hours of video streaming. Processor speed is good but phone sometime hangs while using surfing. Camera is not upto the mark, I would rate it 3.5 out of 5.Sound quality is good (4/5).I can't anything about the gaming performance as i am not a gamer. All in all the phone is 4.5/5.

  • Samsung M21 best in price
    Mohit Kashyap (Jul 17, 2020) on Gadgets 360 Recommends
    3rd day now using this phone variant 6/128, love design build quality display performance but camera is not up to my expectations picture looks nice but frankly does not looks original it's like and inbuilt face app who enhances colors more and pixels breaks so it took time for camera to adjust though night performance is good. Overall you can go with this in this price.

  • Good phone (please read the review)
    Yithesh Shetty (Jul 4, 2020) on Gadgets 360 Recommends
    Samsung Galaxy m21 is a good budget phone with great features.Its battery lasts long and takes a little more time to charge. I have the 6gb-128gb variant.Its been a month im using it and no problems so far. BUT : This phone lacks some usefull features like - COMPASS, screen recording, app lock, inernet speed at notification toggle, etc You can download 's secure' app from galaxy store for app lock but the downside is it shows lock icon on apps on homescreen.. You can download third party apps to use other missing features.. You can download third party apps to use this features..

  • Issues phone turned to rubbish after update.
    Deepak Kumar (Feb 2, 2021) on Gadgets 360
    I brought this phone on in early january. This phone had only three things that attracted me first is display, battery backup and third was software. Recently I updated to android 11 and one ui 3.0 now battery life is poor initially i was getting around 10-11 hours of screen on time or 2 days battery with one full charge after update it is now giving me around 6-7 hours of screen on time. Before update it was comsumi 2-3 percent on idle left but now it takes 20 per battery if left idle for whole day. If have off auto syn, i have adaptive battery, cpu performance to 70 per, and every setting that samsung recommended me on complaining to them but all went to no vail. Coming to software it feels as if software is quite heavy for exnyos 9611. Hope samsung do anything to help us.

  • Don't buy playing with sentiments of Indians. Buy Lava, Micromax
    Icardwala Dot Com (Jul 6, 2020) on Gadgets 360
    Your phone is merely 6000 cost. No right to take this much money. Even in u r message box it is accepting text in phone number box. Capital in mail I'd box. Not getting connected with mobile data. Need to tap 5 times for one thing to be clicked. Third class phone. Beg in india we will pay you. In India while typing India I should come capital. You are fool and fooling Indians against Ban China movement. Shame on u r thought process.

  • The best phone money can buy at this price
    Pranjal Sharma (Jun 4, 2020) on Amazon
    I bought the Raven Black, 4GB-64GB variant of the Samsung Galaxy M21 for my mother. I'm impressed with the phone's overall usability. Since my mother is not a heavy user unlike me, I decided to go for Samsung by considering the brand value and overall specs of the phone. The main requirements for my mom are- Good display for media consumption, good battery life and a clean and easy to use UI without any unnecessary ads. Since the Galaxy M21 ticks all the right boxes I decided to go for this phone. Moreover my mother was using a Samsung Mobile prior to this and hence she was accustomed with the functionality of the UI.-The display of the phone is brilliant and at par with the Amoled display of my Redmi K20 Pro.-The battery life is also very good and it easily gives 1.5 days backup even under heavy usage. The only complain I have is the length of the charging cable which is very short.- The performance is good too for day to day usage. The Exynos 9511 is fairly capable and I haven't seen any stutter or lag in UI. If you are ahardcore gamer than I would recommend to look for alternative since it would not perform as good as its competition in regards to gaming. For casual gamers it will do the job well.-The cameras on this phone are brilliant with very good image processing done by Samsung. It takes pictures with natural colours.- The speaker output is average. Its loud enough but the sound produced is nothing impressive since it lacks bass and that clarity in the sound output.- The audio output via the 3.5mm Jack is very good as it supports Dolby Atmos.- The fingerprint sensor is very fast but the face unlock feature is not that consistent as it sometimes fails to read your face.Hence, overall it is a great value package from Samsung and I would highly recommend this phone to everyone looking for a good phone at this price point unless he/she is a heavy gamer. Thanks for reading.
