Samsung M series is one of the popular series right now from Samsung and this series mainly focused on giving competition to the Chinese rival. The Samsung Galaxy M21 has a simple but elegant design, it has a plain back but to reduce the cost Samsung just used some high-quality plastics instead of their metal back. The Triple camera back is not that much projected out so you don't need to worry about the wobbling, if you put a back case even don't notice the projected Triple camera. And the Fingerprint sensors are also rightly placed within the reach of the finger.

Coming to the front, as same Samsung nailed the Display with an AMOLED display with good contrast and the front has a good aspect ratio of nearly 91% of the screen displayed so you can enjoy your movies. The Front camera is like a bubble on the top but that is not at all annoying while using, and a speaker is at the top of the front camera More importantly it comes with a Gorilla Glass 3.


Samsung Galaxy M21 comes in two variants one with 4GB RAM & 64GB internal storage at Rs.13,999/- and 6GB RAM & 128GB internal storage at INR 15,999/-Both are performing well. The Processor is Galaxy M21 from Samsung itself it works on the Samsung Exynos 9611. The processor works fine. The basic apps work fine and multitasking by switching the apps is also fine and smooth, but when we work on some heavy apps there is a slight slowing down. Fingerprint sensors and Face recognition are a bit slower than their rivals. The AMOLED display is awesome for watching movies, but the speaker is slightly smaller than their rivals. 

Game Performance

The Game performance of Galaxy M21 is fine with games with mid-range graphics. we tested PUBG in High Definition it slightly lags but in Mid graphics, it works smoothly, with no issues with that.

The Triple camera setup at the back is like that of Galaxy M30, with a 48MP Sensor and 8MP wide-angle sensor & 5MP sensor. The Camera takes good pictures in the Day, and the User Interface of the camera is also easy to use. The camera Locks the focus very quick and responsive but the scene optimizer in the M21 bit lags. The Wide-angle camera does its job well, but it lags the sharpness of pictures in this mode. The Primary/Back camera is set at 12MP picture quality by default to save memory but you can change it to 48MP in settings.

Coming to the Front camera, the 12MP camera takes the picture in 12MP but if you change the aspect ratio you can get 20MP quality pictures, It is awesome but when you zoom the grains are visible. The Beautification option is set as default you can change the setting if you wish.


The battery is toooo Big in this 15K category with its 6000mAh battery, with this, we tested for a loop movie test and it lasted for 21 hours, and for gaming like PUBG, it's 3-4 hours. So you can enjoy your movies without hooking up with the charger point.

  1. The AMOLED display takes the phone to a different level for movie lovers and YouTube usage
  2. The Battery lasts for nearly 3 days for normal usage and 21 hrs for looped movie watch
  3. The cameras were decent for day photography.
  4. Different Camera modes such as slow-motion camera mode and wide-angle camera are available.
  5. Android 10 and the User interface are user-friendly.
  6. A good screen aspect ratio of nearly 91% of Screen is Screen.
  7. Even with that size Battery, it is not Bulky.
  1. Not for Heavy gamers and HD PUBG play, for normal games it's fine
  2. Heavy games make more Heat
  3. Fingerprint sensors and Face recognition are not very quick.
  4. No Headset/ Earphone is provided along with the pack needed to be purchased in the aftermarket.
  5. No Metal Back only Plastic without any reflections.

Camera:  4.1/5
Battery:  4.3/5
Display:  4.5 /5

Total:  4.3/5
