What this means for a repair

  • The curved edge means a standard flat protector will lift along the sides. These need a full-glue or UV-cured protector shaped for the curve, and the cure has to be done properly or the edge lifts within a week.

    Glass types explained →
  • The punch-hole has to clear the camera exactly. A protector cut for a centre hole will sit over the lens on a phone with a left-offset one, and the customer will see it immediately.

    Common fitment mistakes →
  • An OLED panel means the glass and the display are usually laminated as one assembly, so a cracked front is a full-assembly job rather than a glass swap. Price the repair accordingly before you quote.

    Glass, digitizer or display? →
  • With no headphone jack, audio runs over the charging port. A worn port can present as an audio fault, so test both before replacing the flex.

  • The water-resistance rating does not survive being opened. Replace the adhesive gasket on reassembly, and tell the customer the rating is gone either way — in writing, before you start.
