Re: 4.4.2 problems for xperia z zl and zr / LIFELOG APP

I don't know if someone from Sony is still reading boards about Xperia Z/ZL/ZR family anymore. I was a happy Xperia Z and Tablet Z owner for a year, until 4.4.2 KitKat upgrade. Now everyone is aware of the battery drain issue, I am not going to tell the same story BUT my great expectation was Google Play Services update to 5.0.84. Apparently nothing has changed. 


I have another battery killer now: Sony SmartBand application LifeLog. Lifelog has been updated to v2 in early July and now it prevents the phone going into Stamina mode. Sony recommends this (lines are from Google Play Store):


To improve battery performance we would advise disabling the transportation detection. To do this go to Lifelog - Settings - Logger. Uncheck the Activities checkbox and you will not get any physical data from your device, only from the SmartBand.


OK.. it seems like there's a solution, right? You're wrong. What Sony recommends is like you are buying a car and you notice that the car is consuming a lot. The manufacturer recommends you to turn off the engine so that the consumption would drop.


I own lots of Sony devices, A99, A58 cameras, lots of Sony Zeiss lenses, a Sony Vaio laptop. Sony MDR-1RBT headphones, a universal remote controller device, Sony USB sticks, Sony USB harddrives and some other gadgets I cannot recall right now. The support for Xperia devices is TERRIBLE! It seems like Sony does not test the new releases and just use us as crash test dummies.

Re: 4.4.2 problems for xperia z zl and zr

Very unsatisfied with this 4.4 version, regret updating to it but still hope Sony could take these problems into consideration for the next version because if they don't, they're gonna lose lots of Sony consumers trust and confidence in them.. They are:

1. Battery usage and over heating, as mentioned bu the others, I don't have to go on I guess
2. The super laggy home screen and notification section, first I don't get why they split the notification plane to 2 sections, which is so not user friendly for existing Sony users, we're already so used to the one slide only notification plane why change? Second, for version 4.3 the home screen will appear the moment the swipe unlock is activates but has a brief 1sec lag which is not fancy at all.. Please do something about it
3.overall performance drop of all the apps in the phone, never have I experience lag issues before the updates and now having multiple crashes everyday when I open multiple apps at once, if this goes on I'm really going to consider switching to others as this is a big no no for me
4. Lastly, just a minor personal preference suggestion, the previous start up wallpaper/background is way better than this new blue one, it just made Xperia phones looked "cheap", as China brands like oppo and Huawei could have better displays than that I think please do something about it cause I still believes Sony is cool that's why I bought it the 1st place..

Problems in build 10.5.A.0.230 - Xperia Z kitkat (4.4.2)

Hello Friends,


I just got 4.4.2 update yesterday (OTA). I installed that from my android 4.3 and was disappointed because 4.4.2 makes my phone more laggy and slower.


When you scroll menus it jurks and hangls little bit. It was not butter smooth like 4.3.

The only change I notice is like below :


1) Notification placement

2) Little UI twicks




1) Lagging navigation/scroll

2) Typeing is not smooth like android 4.3

3) Battery is ok.

4) Camera is not improved at all from 4.3

a Jelly Bean in hot weather is better than Kit Kat

So yeah all the bugs everybody has been reporting are true to the Kit Kat; overheating, battery drain and restarting loops.


It seems some solutions work for a little while but their probably do to cache clearing... anyway after many pc companion restores, repairs and etc. I've had it and flashed 4.2.2, went to sleep with 100% battery woke up with 96%... no restaring no overheating for 3 days so far.


I suggest you do the same also, before it gets hot out and that battery blows or ruins your phone.



*not responsible for any damage caused by the use of flashtool and or flashing the phone yourself
