Ear Speaker and Front Camera working on and off
I have an iPhone 7 plus that I recently repaired that the ear speaker works randomly and the front camera is very slow at coming up and/or sometimes doesn't work in apps such as snapchat. This iPhone has been fixed previously and has been working fine.
Now I've replaced the front camera and speaker with a known working original with the same results. I also uncovered another issue. The phone will get stuck on the Apple logo after rebooting and will only boot normally after I do a hard reset. I tried different batteries and a different front camera flex with the same result. At this point Im scared to update to 11.3.1 or even restore it, because I'm afraid it wont boot properly and brick the phone
Any words of wisdom before the customer makes an insurance claim? Is this maybe a software issue and not a hardware issue?
