So I have an iPhone with a screen I replaced but has 2 bright spots on top of the screen. Is that related to another problem on the board, bad connection, or bad screen? I also have some issues with the home button being loose. Secured but loose. Any ideas on why that is or what I can do about it?
3 things here,(1) screen is really bad quality and has a bad back light installation (2) you installed the back plate too forced (3) Ear peace is too close to the back light. And if you feel the home button loose that make me thing that is a really bad Quality Screen. You can try removing all the components of the screen a leaving the screen without back plate and camera and ear peace and if that light spot disappears something is touching the back light layers and basically is just a bad quality screen.
