Lollipop update problems with M2

[S4chin]

Yesterday i have updated my M2 with lollipop, After that i am facing couple of issues.

1) Huge battery drainage

2) Memory low issue ( first i have reset the device with wiping all the user data after that i have updated my device. It consumed lots  of memory for OS, after installing 8-10 applications its started showing memory low msg)

3) Calling feature is complecated than before

4) Camera is not clicking pic with touch click

5) Walkman ( music ) most of the features is not available which is available in 4.4 ( headphone selection option is not good )

6) Most of the system application is not using full screen mode

7) Brightness issue ( i was able to see the screen properly at lowest level in 4.4 but not in 5.1 )

I'm sorry to hear about that, you have 2 options to downgrade the phone, either contact your Local support or use flashtool. 

As far as the apps, if you moved the apps to the SD card then you will have to reinstall them.

As preinstalled apps are unabled to uninstall and we get only 2 to 3 gb of phone memory for SONY M2. And it makes phone working lagging and slow.
