Z1 Compact losing WiFi, bluetooth & NFC connectivity since last update

[Anonymous]

Has anyone else noted that connection to Wifi, bluetooth or NFC devices are lost randomly and have to reboot the phone to get reconnected.  Seems to have started since update to Android V5.1.1 and more so since update to Build Number 14.6.A.0.368.  It's really annoying!

@viridis is the Sony fount of knowledge here. Perhaps he can give you some advice when he sees this.

Do you have stamina mode on at all?
Is there settings to affect time out of connection in the wifi and Bluetooth settings?
If not it may be that something may have got a bit wonky with the 5.1 update.
Try a factory repair installation with pc companion (back up files first) and see if it rectifies the issue.

I did have stamina mode on but have turned it off but no better.  Will try a factory repair.  I've had the phone a while so doing this might not be a bad idea.  Thanks.

Ran through the factory reset, blooming painful that was!  Just finished off resetting the phone and found that it as lost connectivity again to Wifi & NFC items.  Restarted the phone and connections back.  Any other advice before I go and have a lovely chat with the O2 Gurus in store?

Maybe mention @viridis again here...as he was posting on the thread before.?

If reset didn't fix it, it's probably something more in depth.
I don't think they will both just turn off due to a setting so maybe next port of call would be direct to Sony?

OK, I'll give them a go.  Thanks for the help.

I'll second that.
Forget O2 and go directly to Sony.
Just for info, I updated my Z1 last week and have no such problems, high battery drain yes, but not dropping any connections.
