Design and Display

The Samsung Galaxy S21 and S21 Plus feature a spectacular design with a unique style camera module that differs entirely from the rear layout. Although the screen on both phones does not appear to be curved, it must appear robust and compact. The company is planning to launch several strong colors, such as Phantom Black, Phantom Pink, Phantom Violet, and more. The Phantom Violet stands out because its camera module is painted pink, while the rear panel appears in violet, which contributes to the overall construction.

Initially, an Infinity-O notch is covered in the displays of the S21 and S21 Plus measuring 6.3 and 6.7 inches, respectively. Packed with extremely fine bezels, the two devices offer 2X Dynamic AMOLED with a smoother refresh rate of 120 Hz and HDR10+ to offer exceptional contrast and colors. You would have no problem carrying the S21 series devices outdoors, as they incorporate a maximum brightness of 1600 nits. For resistance to scratches and drops, the front glass is made with Corning Gorilla Glass Victus.

Memory and Internal

On the one hand, both the Galaxy S21 and Galaxy S21 Plus will be upgraded to the Exynos 2100 chipset in international markets, including India and other Asian countries. On the other hand, the Snapdragon 888 chipset will specifically equip them in the USA, Korea, and China.

Based on an excellent and efficient 5 nm architecture, SoCs need no introduction when it comes to faster and more fluid UI performance. In addition, the devices retain the ability to play 3D games like PUBG Mobile or COD Mobile at their highest graphics settings.

Coming to the custom UI, the devices boot into OneUI 3.0 running on Android 11 OS. In fact, OneUI is considered one of the cleanest UI after Stock Android. In addition, you can see an updated quick panel, improved Samsung Dex, improved Bixby assistant, etc.

Turning to the memory partition, the Galaxy S21 offers two memory variants, that is, 8 GB of RAM with 128 GB of internal storage and 12 GB of RAM with 256 GB of internal storage. Now, the next flagship of the Galaxy S21 Plus comes online with 12 GB of RAM and the only thing that varies is the internal storage. The company allows users to purchase three variants of UFS 3.1 storage – 128 GB, 256 GB, and 512 GB. It is not new that these memory chips are highly powerful and also faster compared to mid-range phones.


Interestingly, the camera hardware on both devices is identical in terms of megapixels and performance. Each comes with a 12 MP primary snapper, an impressive 64 MP telephoto lens, and finally, an ultra-wide 12 MP sensor again.

Thanks to the Samsung team for incorporating several interesting features like 8K video recording, 960fps slow-motion, OIS for super-stable videos, HDR10 +, etc. In addition, the large main sensor kicks in for phenomenal low-light photography. With this professional-grade camera system, you can capture breathtaking photos with excellent highlights, dynamic range, and shadows.

Likewise, they limited the selfie camera to 10 MP for each but did not fall into the resolution. Samsung’s optimizations and post-processing will change the whole game, so you will get very clear and fabulous photos. Even in the selfie module, you can see the 4K video recording feature that looks amazing.

Battery and Others

The S21 consumes power from a large 4500 mAh Li-Po battery, however, the Plus variant has an advantage with a larger 4800mAh Li-Po battery. These two batteries feature a 25W fast charger with support for Power Delivery 3.0 and 15W wireless charging. The next big draw is the AKG tuned stereo speakers that can literally soothe your ears if you love to listen to music. You should have no problem taking your phone outdoors, even in the rain, with IP68 dust and water resistance.

For now, we have no information on the prices of the two devices and we guarantee that you will be updated as soon as we receive the same. But the S21 is expected to be priced lower than the galaxy S20 according to some reports.
