About OnePlus 8T

OnePlus 8T is the first smartphone in which we find Android 11 natively inside. Obviously, the OS is customized with OxygenOS 11, the stock UI of all OnePlus phones. However, it is worth highlighting the main functions: among all, the always-on mode allows you to check notifications even when the screen is locked and without lifting the smartphone. The graphics reflect that of the adaptive screen (which is nothing more than a kind of not-always-on request). The new Zen Mode 2.0 allows you to block the smartphone’s use now for longer periods and even in groups remotely.

Among other new features, the dark mode has been refined. The recording can transcribe the text (at the moment only in English and Chinese). The entire graphics have been slightly rearranged by introducing a new font. In addition to this, we find everything that we had appreciated from the previous versions. Together with these functions, the fluidity and speed of the entire system are still in place.
