System UI not responding

[Dean06]

I had problems previously with the phone randomly restarting every 10-15 minutes. Following advice from other threads I have done a software repair with the Sony Xperia companion on my laptop and ever since the restart it is still crashing with no new apps installed but now come up with the error message 'system UI not responding' before it crashes.

On a side note ever since I did the repair the fingerprint manager in the settings has disappeared which was working fine before. 

Any help is appreciated.

@Dean06;

Having done a software repair with Xperia Companion and having that kind of problems without installing any backup or apps I would advise you to contact your local Sony Support Team to get your device hardware looked at.

P.S. You can try repair the software again with the Xperia Companion just to see if the results are the same.
