Absolutely atrocious impact on system performance. Any action I try on my Z3 now freezes the phone for about 2/3 seconds before it responds. Not big a deal I guess, but previous version was MUCH more stable. Also, battery seems to last only about 75% of the time as to the previous version.
Bluetooth would not stay off. Each time i turn it off it goes on in 5 seconds…
This update has caused the issue. Any ideas how to fix it?
