Fairphone Secret codes


I am buying a used Fairphone and wanted to do a performance check, are there ‘secret codes’ to do this?

Thank you.

There is an App for that: Secret Codes

EDIT: (info from the App)

225: Calendar info
4636: Testing
8477: Home Screen tips
36245: Email
87410 / 2872710 / 2872713 / 2872714: Bluetooth
3646633: Engineer Mode

Just enter *#*#Code#*#* in your Phone App to get there.


Thank you for your help!
