Camera not working and overheating after screen repair
I recently did a DIY screen swap of my Samsung Galaxy S8, following the guide given here. The phone was working find before the swap and now I’m having the following issues;
1/ Front and rear camera not working
2/ Iris recognition not working
3/ Overheating (heat can be felt near the power button)
I cleared the cache and data of the camera app, and restarted the phone a couple of times. I tried disassembling all the components and putting them back together. Even tried cleaning the components slightly with the use of some isopropyl alcohol. But nothing seems to work. Little bit desperate to find out what the cause could be.
I wanted to ask if anyone could help me, before I take it to a service centre.
The symptoms I’m seeing are;
1/ The front & rear camera are not working.
2/ In the diagnostics menu (*#0*#), everything works expect for the sensors section, and both camera. When I try to get these, the screen shows blank and freezes.
3/ LED notification indicators do not work, even when battery is low or when the phone is plugged in.
4/ When the phone is plugged into charge, it either stays on 0% or charges to 5%~6% and then starts to go back to 0%. During this time the phone (near the power button) starts to get really hot.
