I upgraded my FP2 on Thursday to Android 7 (via update launcher), but I’m very unhappy with it.
My favourite apps are not usable any more, the whole system is extremely slow (it was never fast, comparable with other smartphones, but now everything freezes or directly aborts).
I already rebooted several times and reinstalled the respective apps.
Permanently I receive error messages “…does not respond”
The apps worked well directly befor the upgrade - so there is no other app version which may have caused this issue.
How do I revert this Android 7 and downgrade back to Marshmallow?
Thanks in advance for your help, it is really appreciated,
