Phone FixAbout this list
Every problem on the site is listed above by kind. The box filters the list as you type: try "charging", "hot", "sim", "wifi", "apps", "pin".
Phone faults fall into a few families, and knowing the family tells you where to begin.
| Family | Typical cause | Where to begin |
|---|---|---|
| Slow, hanging, crashing | Full storage, one bad app, heat | Phone slow, storage full |
| Battery and charging | An app in the background, weak signal, a worn battery, a bad cable or dirty port | Battery draining, not charging |
| No network, data or Wi-Fi | The plan, a setting, the SIM, the router | No network, mobile data |
| Sound, calls, Bluetooth | A blocked grille, the wrong output chosen, an old pairing | Call sound, Bluetooth |
| Dead, frozen or locked | A flat battery, a stuck system, a forgotten lock | Will not turn on, forgot PIN |
Software or hardware?
A quick way to tell: does the fault survive a restart, an update and (on Android) Safe Mode? Did it begin after a drop or after getting wet? Is it limited to one physical part, such as one strip of the screen or one speaker? Yes to these points to hardware, and no setting will cure it. A fault that began after an update or a new app, and comes and goes, is software.
The steps that erase data
Only three things on this site erase your phone: a factory reset, a restore from a computer, and erase from Find My Device or Find My. Each is the last step on its page, each is marked, and each needs the Google or Apple account afterwards. Everything else is safe to try.
Which fix should I try first if I cannot find my problem?
Restart, free some storage, update the system and apps, and on Android try Safe Mode. Those four cover most software faults.
Is it worth repairing an old phone?
A new battery or charging port is inexpensive and can give an old phone years more. A screen on an old model may cost more than the phone is worth. Ask for a quotation before agreeing to any repair.
