Hi @Abro,
Sorry to hear you have a problem with your FP5,
you can read more about this issue in this topic above.
You can ask your company if their is a way use the company apps whiteout a fingerprint scanner (pincode for example)
Currently the only permanent solution i can give is to contact your Fairphone reseller for technical seport and repair.
this should be covered onder warranty.
if you bought your phone directly from Fairphone contactsupport using the Fairphone app on your device, expect a waiting time of more than 2 months before you get a response from Fairphone. the live chat is a faster but it can be difficult to get contact with a agent.
Amsterdam time zone.
greetings
Tom
