What to check before buying
iFixit score
7/10 provisional · Rubric v2.2. Source: Smartphone repairability scores (iFixit). How to read the score.
iFixit labels this score provisional.
Rear glass
The back-glass guide describes a combined unit with the flash and wireless charging coil. Damage to that assembly can affect more functions than the visible glass.
Screen and battery
The screen guide warns that the battery remains connected during initial display removal. iFixit also documents battery replacement with a separate procedure.
