Choose between display-only, display-and-frame and service-pack replacements, then verify every function before final sealing.

Core ideas

  • Determine whether the screen assembly includes frame, fingerprint sensor, earpiece mesh or transferred brackets.
  • Test image, touch, brightness, proximity, cameras, speakers and biometric functions before installing permanent adhesive.
  • Protect OLED panels from pressure points and route flex cables exactly as shown in the guide.

Decision rule

A cheap panel that fits physically may still lack correct colour, refresh rate, touch controller or fingerprint compatibility.

Apply it on your phone

Create a pre-seal functional test sheet and require every item to pass before closing the phone.
