Z5 Compact phone app slow, very slow.

[Chrix]

Hi all. I'm really unimpressed by the Z5 compact. The phone app is super slow. Also, I have to restart the phone each time I want to place a call cause theaudio doesn't work.

Is there a solution or something I can do to make it work?

I suggest that you try to repair the phone software using PC Companion..

Before repairing your device you may want to backup your information first. Check out this topic for more information on how to.
