Hi @clairesoleil ,
Has the phone been dropped recently or gotten wet at all?
How old is the phone?
There is a 2 year ''manufacturer's warranty'' on the phone. If the phone hasn't been dropped or gotten wet or been generally mishandled then I suggest that you verify the purchase date of the phone to ensure that the warranty period is still valid. If it is still within the warranty period, then consult the [https://www.fairphone.com/en/legal/fairphone-2-warranty/|manufacturer's warranty statement] as to what you have to do to make a claim for a possible manufacturer's warranty repair or replacement.
