just thank me if this method works for you.. tnks
Can't update my xperia z 5.0.2 into 5.1. when i download and install the update then my phone auto restarts then it always says "Update failed try again" can somebody help me?
please for all of you complaining on battery drain, check your WiFi setting course that's were it hit all of yo thanks.
Thank goodness I never upgraded! Not liking all the negative stories about it, and my xperia 5 is working just fine thank you.
Don't ever upgrade your phone to 5.1 version!!! I hate it.
* Battery drain so fast, it won't last 8 hrs.
* Camera is blurry and very slow (Poor Quality)
* Unstable wifi signal
No wonder why majority of the users hate 5.1 upgrade, it sucks! I'd rather use Jelly Bean than Lollypop.
is there a new update now to fix fast battery drain? i updated my xperia z 4.4 to lollipop now but i notice fast battery drain any help please?

So Finally Lollipop Is Here For Xperia Z!
So what are your reviews for Xperia Z running lollipop ?

-Display tweaked much better
-Better Performance than Kitkat(Obvious)
-Battery Life? No Comments Yet
-Ultra Stamina Mode
-Multi User support
-Improved Camera performance (Great Photos in Backlight)
-Charging Very Slow (Used a 2A Charger)
-Heating more dan kitkat
-No Screen recording(Maybe not supported)
Lollipop 5.1.1 [.222]
-Battery better than 5.0 bt not good as 4.4
-Settings New Icons
-No freezes or glitches

-Stagefrieght Exploit is not yet patched in this build
Updated to 5.1 easily. Everything is fine expect for Photos. When ever i open any photo it crashes and says stoped working
Z1 has been "installing" 5.1 for hours! No indication of progress - if this is indeed happening. Can't find how to force stop of process.
