https://ibb.co/DtyMHM1 I don't know if this is the right place to ask this, but i have nowhere else to ask it, i found a galaxy s8 for 150 dollars in very good condition except it has a small keyboard burn-in visible only on white screen, now i donpt know if the phone is worth it and if i get it how can i further hide the burn-in and prevent it from exceeding?
