Is the S21 waterproof?	There is an IP68 rating for the S21 which allows your phone to remain underwater for up to 30 minutes at 1.5 metres. In addition, dust, dirt and even water dropleons won’t damage it.
Can S21 take pictures underwater?	The Galaxy S21 Ultra has an IP rating but can still be harmed by the water pressure and salt found in bodies of water. Although the Galaxy S21 Ultra was catching water droplets, the photographs it took of the water turned out beautifully.
How many years will S21 last?	Users of the Galaxy S21 series can get four OS updates and five years of security support from Samsung.
How old is Samsung S21?	The Galaxy S20 series is their main target. On 14 January 2021, the Galaxy Unpacked event announced the first three S21 models and the FE was unveiled on 3 January 2022. The first three phones were planted on 29 January 2021 and the FE was started on 11 January 2022. On the same side, S21, S21 FE, S21+ and S21 Ultra are all included.

Create and Construct

The S21 Galaxy from Samsung has a small, yet well-made design with a front protected by Gorilla Glass Victus and a polycarbonate rear, inside an aluminum frame. The Pixel 6 Pro is only 5.97 x 2.80 x 0.31 inches and 6.03 ounces, so it’s easy to pick up and carry around. You can find it in Phantom Gray and Phantom White and the matte body makes them less likely to collect fingerprints. You can easily use separate apps by customizing the edge panel on your device.

Weight	6.03 oz (171g)
Materials	Aluminum, Gorilla Glass Victus, Polycarbonate

Costs are reduced by covering the back in polycarbonate and not including a telephoto lens. This phone supports charging of other devices over wireless technology. Thanks to the absent home button, this model can be opened with modern gestures and a face-recognition camera under the screen.

Galaxy S21 Display

The Galaxy S21’s screen is 6.2 inches, Dynamic AMOLED 2X with a 2400 x 1080 resolution (421 PPI) and HDR10+ is supported. Because the peak brightness is 1300 nits and it features a 120Hz refresh rate, watching TV outside is even smooth and comfortable to watch. The front camera is located using the punch-hole design.

The display is ideal for media and gaming, but the lack of an Always-On Display is a drawback. Reviewers praise its clarity, though the punch-hole is less modern than under-display cameras.

Software and Processor

The Snapdragon 888 (or Exynos 2100) CPU and Adreno 660 GPU give the Galaxy S21 good performance. The RAM on this phone is 8GB and it comes with storage of 128GB and 256GB. One UI 5.1 is running on Android 13 and you can also update to Android 15, receiving support for 4 years or more.

The processor handles multitasking and gaming well, though it may warm up under heavy loads. AI features like Bixby Vision enhance usability, but some users report minor software glitches.
