Xperia U Performance after latest Update

[Piush]

Hi

I have noticed that after the latest update to Android 4.0.1, The phone is working little slow.

However, it became further bad after I installed an Antivirus.

Is it natural or there can be any suggestions

Thanks

stay away from antivirus, taskillers, task managers, and battery apps

Nope,not needed.Android is clean as a whistle,also RAM refreshes at restart.

It's happening too in 6.1.1.B.1.89 and 6.1.1.B.1.100 firmwares. I don't use them anymore. I unlocked my boatloader and installed 6.2.A.1.100 firmware. This device works like a charm with Android 4.1.2 Jelly Bean. Sony, you should have released it for Xperia™ U too officially. You abandoned it unfairly.
