Screen damage: glass or display?
It helps to know whether the damage is to the glass only or to the display underneath:
- Glass only: cracks you can see and feel, but the picture underneath is clear and touch works everywhere.
- Display damage: lines, black or coloured patches, bleeding colour, flicker, or areas that do not respond to touch.
- Burn-in: a faint image, such as the keyboard or status bar, that stays visible on a plain background.
Photograph the screen switched on (a plain white or grey background shows faults best) and switched off at an angle, so both kinds of damage are visible. Mention cracked back glass or camera lenses too.
Battery condition
On an iPhone, Settings, then Battery shows the battery health as a percentage, or a service message. Some Android phones show battery health under Battery or Device care; others do not show it at all, in which case just tell us how long a charge lasts.
If the screen is lifting away from the frame, or the back is bulging, the battery may be swollen. Stop charging the phone, keep it somewhere cool and tell us in the form before anything else is arranged.
Other faults to mention
- Will not turn on, or stuck on the logo.
- Will not charge, or only charges at a certain angle.
- Face ID, Touch ID or fingerprint not working.
- Cameras that do not focus, show spots or will not open.
- No sound from the speaker or earpiece, or a microphone that others cannot hear.
- Buttons that do not click, or no mobile signal.
- Liquid damage: what it was, and when.
