Testing the display

• Display connector

Before assembly, switch on your phone to test the spare part.
Take the new display, but don't remove the backing films yet.

1. Put the display on one edge and plug in the connector. This may need several attempts. Make sure not to damage the connector.
2. Drag any app across the sceen in a zig-zag pattern. If it doesn't bounce back, everything's fine.
3. Test the display's minimum and maximum brightness and look for any pixel errors.
4. If everything is ok, switch off the device again and unplug the display
