Poor network connection after Marsmallow update

[LeonMichelle]

Since I did the update on my Z5 I almost never have a network on my o2 phone and the WiFi won't work properly. Everyone else in the house are not having the problem so I know it was the update, also my battery is draining very fast, my screen keeps freezing with a load of mad colours. Is anyone else having these problems?

Please try to turn off double tap feature by

Setting >Dispaly> Double TAP

Take a look at my post about network disconnect, as someone from the UK has also said they are having the same issue.

Try switching to WCDMA preferred in your mobile network settings and see if that has an improvement.

Colours, I cannot really comment, but battery drain absolutely. My battery improvements have tied in with changing mobile network settings, so I'd say there is something in that.

Try rebooting in safe mode and see if the colour, freezing and wifi issues continue as there might be an application causing some issues.

Take a look at posts in here too as others might have reported your issues. the more "me too"s lead credence and weight to there being wider issues with the firmware.

The double tap feature isn't on. If I cam get use of a pc I will try that. I shouldn't have though as these shouldn't be problems. SYNCR0S I'm useless when it comes to stuff like this but will have a read through your post and others. Thanks for the help everyone
