Navigation keys not responding, can't do factory reset. Is there a solution?
Hi @Jehennah,
I'm sorry to hear this. I recommend that you reboot your device to safe mode to see if this behavior is caused by one of your downloaded apps as these will be temporarily disabled in this mode.
If you are still experiencing the same behavior I'd recommend that you perform a software repair using Xperia Companion.
Let me know how it goes.
