I do not have navigation keys "navbar". Touchscreen work all work, just at one point the keys have stopped working and that's it! Please help me !!!! I would really appreciate it !!! Phone SONY XPERIA X3 +. Thank you for understanding!!!!
I'm sorry to hear that. I would recommend that you try and reboot your device to safe mode to see if this behavior is related to one or more of your downloaded apps as these will be temporarily disabled in this mode.
