why my iphone7 screen when i lower the brightness several times a dark transparent will appear on half of the screen? but it will eventually disappear. my lcd is fine, no crack or anything. but i recently got it replace and fix because i dropped it on water. do i need to go to repair it again or what? am i overreacting and my phone is actually fine? please i need help asap because i don't want to spend another money for this goddamn phone 😭
