The case of my Fairphone 3 is broken on the lower left corner. About 5mm of the plastic and a small metallic thing are broken. Could it be that at that location an LTE antenna is located? My phone sometimes doesn’t really have reception even though the symbol shows an OK value.
Good idea, but as you said it’s not written down.
I manually switched to 3G/2G so I have at least a working connection.
I’ll probably switch to a FP5 as this issue and the one with the fingerprint sensor on Android 13 are too many problems.
