For example, if the phone won’t charge, check the cable first. Try a different cable and charger. If that doesn’t work, the port might be the issue.
Diagnostic steps:
Power On Test: Does it boot up?
Screen Check: Any cracks? Is it responsive?
Audio Test: Do speakers and mic work?
Charging Test: Does it show charging?
Button Test: Do all buttons function?
Connectivity: Wi-Fi, Bluetooth, Cellular signals.
Accurate diagnosis saves time. It prevents unnecessary repairs.
