Personally I feel the update degrades the phone battery life with the task manager added in goes down drastically p, the hand off between Wi-Fi and mobile network is slow and data connectivity is lost till a restart is completed. And dialing calls, I have to dial a call twice to get it to go through, the phone disconnects immediatelybsfter dialing he first without any ring/disl-tone.
My 2 cents in the update and YMMV
