Problems since 4.3 update

[chrisj59]

Hi, I updated my Z1 to 4.3 recently and it has gone from being a very stable and reliable phone to a frequently frustrating one! I get frequent screen freezes, especially when I try unlocking using a pattern, it accepts the pattern but fails to unlock the screen, then the screen goes black and even pressing and holding the power button fails to get a reaction and you just have to wait for it to start responding again! Also I am getting apps such as FB and Rocket Music Player freezing during use and I get the warning that the app has stopped responding so I have to close it.

None of this happened prior to the update to 4.3 so what should I do and is anyone else having similar problems since updating?

Thanks

Same with my Z.
It only happens with Stamina activated. Only on 4.3,it was never an issue bevor.
As soon as I connect the phone to the charger it wakes up and everything is fine.

Well it almost sounds like a chant, but may i suggest to repair with SUS.

I have noticed that with every update, there is some sort of glitch.

You can repair the phone with SUS but you will loose all your data, it blows but he better then nothing.
