Fairphone is known to have several hardware related problems, but they usually ignore or do not acknowledge them. Recently they tried to argue a hardware problem (ghost inputs) can be solved via firmware update, but of course it couldn't. Additionally you lose support for device when using custom roms (even /e/os). They only support google Android. You could buy from Murena but they can not help with hardware or firmware issues. Fairphone is very to patch their devices in terms of security.
But google is google. I would never give them money.
