The glass panel covering the back camera has a crack in it. Can this be replaced? Both back cameras still work, but small bits of dirt start creeping in through the crack.
Yes, look on eBay or replacebase. For now put a piece of sellotape over the glass to stop more dirt getting in. Update (10/06/2022) Safest way to avoid getting more dirt and possibly damaging the camera is to remove the back cover the apply heat to the glass with a hair dryer or hot air station then pushing the glass out from the inside. Riskier is to apply heat then pick out the glass with a craft knife or tweezers.
