Z5 keeps restarting after update unregularly

[Saschahey]

After the update 2 days ago my phone keeps restarting. It can run for hours or restarts after just minutes. I have not figured out a pattern and most of the time it is just idle in my pocket. Anyone else experiencing this?

Since there isn't an specific pattern, you might want to reinstall the latet update with XC
