Hello, after upgrading to android 8.1 from beta labs, I began to notice the "phantom" icons of pink color from status bar when rotating in a horizontal orientation, as if the display had a memory effect, sometimes the elements of recently closed applications are displayed. Noticing this, I rolled back to android 8.0, but the problem did not dare. Does anyone have a similar problem? Or is it a problem with my phone? Should I carry the phone to a service center? Pls help.
