iPhone making crazy noise and restarting when home button is pressed
I replaced a charging port on iphone 8plus. Was very careful when taking everything apart, put everything back together and tested the charging port,and it was fine. Charging port worked. Started testing the screen and when I pressed home, it made this crazy beep sound and would sometimes restart itself afterwards. Some presses, the button doesnt make the noise, most presses it does. Some presses it makes the noise and then restarts immediately after. I dont know whats going on. iOS is up to date. Everything seems completely fine. No screw mixups, no static discharges, no punctures or drops. The phone also did NOT do this before changing the charge port. PLEASE this is not my phone this is someone elses and i need to fix it asap or they have to get it replaced. I have no found any answers anywhere on this issue.
