OnePlus asserts that its upcoming flagship Android smartphone will have the brand's best display yet. It is now officially the first mobile screen with its 2K OLED specs to meet TUV Rheinland's new Intelligent Eye Protection 4.0 standard. The 13 is now touted to be more practical than ever before, too, with a screen that can be used comfortably and accurately in the cold as well as in the rain.
