5/ Have a hardware checked or repaired.
All 4 solutions above are steps you deal with the software. You totally can do those tests by yourself. If one of them doesn’t work, you might want to check the hardware, especially after you have the screen replaced. Something on the board related to the back-light is probably damaged.
So, how do we know? You broke your screen but the LCD is still good. Do not throw it yet. We will use it to test the quality of the new screen you are going to use for your phone. Replace the broken screen with the new one. Do all the software tests above. Take off the new LCD. Plug the old one back. If the old LCD turns to brighter than the new one, do the following steps.
Double-check the new screen/LCD you have installed and see whether it has a covered back-light connection on the screen’s flat cable. The connection should be covered. You shouldn’t see 3 apparent solder points that connect a thin cable to the main screen cable. These uncovered solder points can short the back-light circuit and cause the brightness issue.
If you can see these points, you might want to cover them before installing the new screen. Another way that might reduce your works is simply buy a good quality screen with solder points are already covered.
Testing or fixing the hardware is not so simple as what you can do in the first 4 steps, but it should be do-able. You think it’s too complicated, so just visit any repair store. Let an experienced technician fix it for you.
