System UI crash - same time every day!

[efalco]

My sytem crashes every single day between 10:30am-11:30am (GMT). The only option I have is to restart it, which it does no problem but I lose my background picture and sometimes crashes a second or third time.

I have tried deleting apps and app updates to solve the issue but I haven't found anything that helps yet.

Any ideas or suggestions?

Have the same problem, i tried a factory reset, and it helped a couple of weeks, but the problem is back:-(. 

And Also the top 3-4mm of My touch screen does not work unless i am in the lock screen.

I think the solution is to install a new OS, not from sony.

But thats no easy task.

but i do belive sony is killing this model:-( never had problems before but suddenly it all breaks down.

Mine does exactly the same. In fact it's just done it a few minutes ago and I've come back on this forum to find out what the remedy was the last time. I remember I was told to turn something off but can't remember what it was. It's worked fine for the past few months but started playing up again yesterday.

Try disabling all alarms. My Z3 compact started to crash every day between 11.45 and 12.15.

Yestarday i have disabled 2 morning alarms (all alarms off) and since then (yesterday and today) nothing happened
