Hello,
so i have a Samsung Galaxy S7 and ive had it or about a year and a half and im quite happy with it. however, i noticed soemthing weird. if i look very closely at the screen (while its off) i can still see an image displayed of the keyboard, while the phone is off! if i press on it nothing happnes, i just see a very faint makring of it. but when i turn my phone on and use it normally, i dont see it at all. any help?
