Wifi randomly disables, blocks restart since May security update

[Doedel]

Hi,

since the May security update (build 34.4.A.2.70) my Wifi randomly gets disabled. Sometimes I manage to turn it on again, other times when trying to turn it on again the activation process does not come back. When I try shutting down/restarting the phone during such a hang situation the shutdown process is hanging in the 'Shutting down' down dialog for >10min before the phone finally switches off. It gets quite warm during that time.

Anybody seen anything like this on their X Compact?

Thanks and best wishes,

Martin.

Its my Problem, too.

You can force restart by holding „volume Up“ while pressing Power. Additionally sometimes The battery–menu is crashing, Not responding, nothing showing.

I caught the logcat output of my latest Wifi failures. It seems there are two types of failures.

First (logcat output filtered to only include 'wifi'):

It could not observe the problem any more since installing the June security update (build 34.4.A.2.85) about 10 days ago. I am keeping my fingers crossed that it has been fixed.

Best wishes,

Martin.
