It measures 161.4 × 75.6 × 7.8 mm and is heavier than the OnePlus 8T at 202 grams.

The OnePlus 8T rocks a glass front and back that is burned into an aluminum frame on the sides. As with the Galaxy S21 Plus, you also get a flat screen here. In my opinion, this improves the user experience because there is no side glare when looking at the screen and it is less prone to shock if you drop the phone.

The device itself is not bulky when weighing 188 gramsand it’s easy to hold. The OnePlus 8T is equipped with a 6.55-inch fluid AMOLED display With Full HD + resolution. It also increases the refresh rate – 120Hz from 90Hz – and the touch sampling rate has been increased from 180Hz to 240Hz on the latest device. The display is also HDR10 + certified. It’s a sharp and vivid screen.

Going back to my OnePlus 8T review, I wrote: “With a great display, amazing performance, long-lasting battery life with 65 W fast-charging capabilities, and a fast user interface, the OnePlus 8T is an easy recommendation.” In contrast, the Galaxy S21 seems one too excellent choice to be! With a new camera setup, top notch performance, and a great display, the Galaxy S21 Plus is also a recommended phone. It depends what you prefer – OxygenOS or One UI.
