Sergiu U. , via OnePlus 7 Pro , Oct 3, 2019 : Hi, Just updated to the last firmware Oneplus 7 Pro. And when I unlock the screen with fingerprint, 2 lines blinking in the botom corners of the screen. Something like: I just draw them, because it is not visible on screenshot. They are blinking like 1-2 seconds and disappear. Does anyone knows what is this and why they appear and if there's any option to turn this off? Thanks!
