Mon problème

Had to replace battery in iPhone 5 because front panel was bulging from battery expansion.

Ma solution

Things went well until replacing the last two screws on the outside. They don't seem to engage with the threads. Front panel is still a little bent from the expansion from the old battery. But I just use the "iPhone 5" as an iPod Touch, it is not my primary device.

Mon conseil

Patience.
