Samsung Galaxy S21 Ultra specifications

According to Agarwal, the Samsung Galaxy S21 Ultra will feature a 6.8-inch Dynamic AMOLED 2X display and the device will run Android 11-based on One UI 3.0 out of the box. It will feature a 108MP primary rear camera and 40MP front-facing camera. The tipster also mentions the flagship will pack a 5,000mAh battery. This is all the info Agarwal could give us about the Galaxy S21 Ultra.

The flagship is expected to come with a high refresh rate screen (rumours suggest it could be 144Hz instead of 120Hz) although we cannot confirm this just yet. Recently leaked renders have already suggested the flagship will feature a design similar to the Galaxy S21 with a centred punch-hole cutout and a unique rear camera module that curves into the frame. In addition to this, the smartphone should employ the upcoming Snapdragon 875 chipset under the hood in markets like the US and China and Exynos 2100 SoC in markets like India. The phone will reportedly measure 165.1mm x 75.6mm x 8.9mm (10.8mm with the camera bump) and come in Black and Silver colours.
