iPhone aftermarket screen problems: what each symptom may mean

Most problems seen after an aftermarket screen is fitted to an iPhone come from the screen type: touch lag or ghost touches, colour and brightness differences, higher battery use with an LCD part in an OLED model and True Tone not appearing. Go back to the place that fitted the screen first.

Key points
  • Touch lag and ghost touches can occur.
  • Colour and brightness can differ from the original screen.
  • In an OLED model, an LCD part can increase battery use.
  • The True Tone option may not appear.
  • Go back to the place that fitted the screen first.

01By symptom

No True Tone optionThe screen data was not transferred
A screen-related warning messageThe phone does not recognise the part

02What should you do?

  1. Go back to the place that fitted it. If the problem is new, tell the service that replaced the screen first.
  2. Check the invoice. If the part type is written, you can see which option was fitted.
  3. Note the symptom. Write down when it happens and in which app.

The difference between screen types is in aftermarket, used and original screens, and the terms “OEM” and “aftermarket” in aftermarket vs original OEM screens. For warning messages and True Tone, see after iPhone screen replacement FAQ.

FAQ

Frequently asked questions

01

Why does touch lag on an aftermarket screen?

The quality of the touch layer or its fit with the phone can differ from the original screen.

02

Does an aftermarket screen use more battery?

If an LCD-technology part was fitted to an OLED model, the backlight can increase power use.

03

Does True Tone work with an aftermarket screen?

If the screen data was not transferred, the option may not appear.

04

Will a screen replacement delete my data?

Data is usually preserved during a repair; still, you need to back up your data before the repair starts (backups are the customer’s responsibility).

Phone works but the screen is black: what to do

If your phone rings or vibrates but the screen is black, the phone is on; the problem is the screen or its connection. Force restart and charge it first. Shine a torch close to the screen in the dark: a faint picture means a backlight fault. If it started after a drop or liquid, the screen is usually replaced.
