iPhone 7 screen has a white dot. A place on the display is very bright

I figured out what's causing the white dots on the screen. It has to do with the silver, rectangular box that's on the ribbon cables. If you fold the ribbon cables up tight on the back of the screen before covering them with the heat shield it causes the silver rectangle box on the ribbon cables to be too high, therefore it's pressing against components in the rear casing when you put the front and back back together. You have to leave a little slack on the ribbon cables when you fold them up and before you tighten the screws on the heat shield. There's an opening in the rear of the phone that's purposely left vacant where this silver, rectangle box should be falling into when the two halves are put together . You may have to play with how much slack you leave on the ribbon cables a few times to get it lined up properly. But once you figure out exactly how much slack to leave and where to line up the silver, rectangular box then you'll never have the white dot problem again. Keep in mind also that the iPhone 7 and the iPhone 7 Plus are a bit different. So you'll have to experiment with each one separately.

As a cell phone technician I’ve fixed hundreds of these phones and had this problem in the beginning until I figured it out. It’s caused by the silver, rectangular box that’s on the ribbon cables attached to the bottom of the screen being too high up and putting pressure on the front screen. Before tightening the heat shield over the ribbon cables try moving the ribbon cables with the silver box down slightly, then tighten the heat shield screws. This will cause the silver, rectangular box to be lower and line up with the opening that’s in the back of the cell phone when you put the front and back together.

"This is from the IC cover on the screen itself, it is not sitting in the phone correctly. We see this all the time, is all you have to do is open it back up and adjust the cable to fit into the slot between the loud speaker and the digi/lcd connector plate (look at photo

) Simply align the ic cover correctly and you will have no white marking on the screen. Very common issue here and an easy resolution. DO NOT BRING THAT INTO APPLE!!!!"

This is pressure between the screen and the inside of the iPhone. Try another screen - check all screws are in correct place and tightened (not too tight) also try removing the metal back plate and reinstalling.

Hi, anyone else who have this problem. I have changed the screen with 3 different displays, and all of them have the dot on the same place. What I am doing wrong?
