So here is my problem so i have an iphone 4 and it is my first iphone to own and hopefully not my last . So when i brought my i phone and few weeks after owning it i have noticed a stuck red pixel on the screen and it was just awful and i have decided to change my screen and the problem was gone and everything was perfect and btw i have no warranty so i changed it with my own money and i didnt go to apple care too expensive (bad idea) . After changing the screen and while watching some youtube i have noticed this awful looking weird thing on my screen which can only be seen when the screen is black. I am new to iphone and i reAlly need your help , any help would be great. Thank you in advance.
When you say "this awful looking weird thing," can you be a bit more specific please? Is it a physical defect or only something that can be seen when the screen is being actively used?
You say you can only see it when the screen is black. If you power your phone off, can you see it then, or does it only appear when the phone is on?
im thinking that i have sent it to a mobile store to fix it and now im thinking that he has probably put some screws wrong causing some pressure or something like that . what do you think ?
