Same here with me, really like the KK, non rooted, full stock, some deactivated apps that I dont use, and of course, Greenify!
[Xperia Z1 General] jonmorris:
Perhaps, but wait until you start using it a bit and installing some apps, or using the camera lot.

I think it's fair to say there are bugs that need to be fixed with another update, and anyone not having problems is either lucky or has found some sort of workaround (or not using certain apps), which isn't ideal.

For me, the phone getting red hot seems to be when the phone isn't doing much. I can play a game and it's fine, but the camera makes the phone heat up. Even using the (Chrome) browser has made the phone start to warm up.

There's no real logic as it's not linked to processor demand from what I can see.

Sorry to hear your troubles, keep trying and best of luck!

Several times I did repair the phone via SUS and PCC, but unsuccessfully, bug with sound is still present.

I tried several times over the flashtool so that I WIPE ALL, but unsuccessfully.

In the end I went back to android 4.3

In the last eight years, which already use a Sony (Ericsson) mobile phones, ( K750i, K800i, K850i, Satio, Arc, Z) and now Z1 I've never before had a problem with sound.

SONY THANK YOU VERY MUCH FOR SOUND BUG!!!!!!!

[Xperia Z1 General] CamilleKills:
Maby I am unpatient but I have paid for this phone 570 pounds 2 months away. I never thought that Sony would be so bad with updates. The device itself is very powerful and satisfies me but first disappointment is that the new features from Z2 are not on the Z1 and second that is very buggy from what I heard.

Honestly I can see that Sony will drop the support of Z1 as soon as Z2 is released worldwide... No bug fixes, no new features. The fact that the service keeps telling me that the update is coming out in different countries at different times doesn't satisfy me because devices like HTC and Samsung is good with updates.
[Xperia Z1 General] slim207rc:
So I've been using the stock 4.4.2 since it's out, bl locked and I'm having more and more issues as time goes by!

I've wiped all and installed again through flashtool, problems reoccurring!

Xtreme signal and wifi problems..

It shows me full wifi signal, doesn't transfer any data though as I try to go only with any app or browser.

I know it's just my phone because we've tested it on different devices, even at the same time, I'm the only one having issues!

Camera doesn't open, showing me an error notification or cam just freezes!

Phone occasionally random reboots.. For no reason.

First time my display acts really funky when touching.. Never had display problems before!

Phones overheats pretty quick, even if I just leave the lockscreen on.

That's the issues so far.

Most annoying are the wifi and reception issues coz I am not reachable for anyone at that time.. And that's just not acceptable! I need to be available round the clock for work!
[Xperia Z1 General] del1701:
I'm in the same boat as you with a sim free Z1, Sony has always left the sim free handsets till last for updates :-\

However it looks like there's going to be another update at some point according to Sony support forum which may resolve a lot of these bugs so maybe we have to wait for that update :(

http://talk.sonymobile.com/t5/Xperi...urs-after-REPAIR-and-RESET/m-p/621599#U621599

[Xperia Z1 General] lelouch20:
I have 'deepsleep' sometimes..i cannot wake my device..reset "power plus vol up" then its ok again.

I will test custom 4.4 roms now let see what happens..
[Xperia Z1 General] CamilleKills:
To be totally honest they should get it right the first time, the testing team should find bugs like that, especially when they are very obvious. I feel like Sony team is so ignorative towards their clients because I got my phone straight from Sony Store. If I had that on contract or buy it branded It would end up cheaper but I felt like unbranded would be the best. Next time I will go for a branded version considering the fact that those get the updates and support first... I think people should write complaints because they will never notice their clients.
[Xperia Z1 General] del1701:
Your absolutely right, Sony were this way with the Xperia's S&T that I had and now this one :-\

But I did read somewhere that the sim free firmware is held back until all networks approve the update because the sim free handsets have to run on all networks

Tbh I am glad that my Z1 is running fine on 4.3 so I can wait a little longer for KitKat.
[Xperia Z1 General] CamilleKills:
All of the networks apart from "EE" are approved because all of the networks apart from T-Mobile in Update checker already have the update... That means they need to be approved.

Edit: I don't think its the case because all of the networks have the update in Germany and the unbranded phones are still on the old build.
[Xperia Z1 General] del1701:
Well it can't be that far off but EE are notoriously slow at bringing updates, well they can't afford to have to many bricked phones going back to their shoddy repair centre in Ashford [emoji35]

Fingers crossed it will only be a matter of days before we get KitKat ;)

I am using the Central Europe 1. UK Vodafone. Handset unlocked from network. Was running 4.3. To prepare for the upgrade. I copied the data from my sd card to my pc. I the factory reset. Flashed 4.4 formatted Sd Card then copied data there.

C6903 updated via Flashtool (generic)

Not seeing the OTA updates any time soon in US, I decided to use flashtool to update my stock C6903 with locked bootloader. Prior to installing KK, I used Helium to back up all my app data as I wanted to start fresh. Flashing took 40 minutes or so and reinstalling 200 apps took a few hours. I restored the app data using the Helium backup and in most cases the apps worked.

Here are my observations on the update:

screen brightness at lowest seemed to be brighter than 4.3

Wallet app allows me to tap and pay (haven't tried it yet but tap and pay was set up and ready for use)

Got LTE working with T-mobile, more than doubling my download/upload speed

No problem with lock screen wall paper or widget

able to load KK camera app with photosphere

Battery seems to last longer (Only used it for 6 days but so far so good); especially with Gravity Screen On/Off app

Confirmed that the phone can go into deep sleep

Have not experienced overheating; phone did run warm sometimes

One issue that recurred once: Phone frozen when I pressed the camera button to take a picture - the screen would show a frozen shot and nothing worked except the volume keys and on/off switch and had to turned off and turned on the phone to reset

Camera seemed to be faster in getting focus when it was not frozen

I hope someone will figure a way to fix non-system app writing to the sdcard without rooting but it is not a show stopper. At least the Xperia camera app can still write to it.
[Xperia Z1 General] Geoffxx:
well my stable device was short lived - one day and I'm back with the mediaserver draining my battery - it was fine for about 24hrs of full use and then went bad again, I now have no clue what is causing this as I've tried everything I can think of but it seems to keep coming back, doing a search on the net reveals many people having this issues on many different devices which leads me to believe it is a Google issue and not Sony

Someone needs to fix this

I wish it was a simple matter to see which app or process is calling on mediaserver and causing this issue but up to now I've been unable to determine
[Xperia Z1 General] jonmorris:
Then you've got the exact same problem as me. If you use the camera a lot, trust me, you'll see this happening a lot more - and also the 'camera not available' error or the overheating one (which will be genuine, as the phone by then will be red hot).
[Xperia Z1 General] djnorich:
Just updated to kitkat yesterday.

Here what i've got so far :

(+)Yeah... we got the old sound tick. the sound same as my psp.

(-)Xperia keyboard still doesn't detect personal dictionary.

(-)I use to using xperia chinese keyboard but the smiley button still not updated yet to emoji.

(-)i think we lost one of stock photo editor. I forgot the names of the app. I love that that app.

It's because of corrupt image file(s) ... Look for any image(s) with no/black thumbnails...delete them...
[Xperia Z1 General] Geoffxx:
all the image files on my phone have been taken with the Z1 camera, those not taken with the Z1 camera were on the device 4.3 - nothing has changed

I will take a look but I expect to find nothing
[Xperia Z1 General] 16ue:
Update on April 3rd:

Bluetooth connection has been excellent - no drops and connection established quickly

More information is passed to SBH52 - Chinese characters for album title and artist are showing up correctly

Removed a bunch of smart extension apps that were draining battery and battery life improved at least 20% with the same usage pattern
[Xperia Z1 General] eclyptos:
Same here. 4.3 just fine and I think is the best choice at the moment. Nobody have to buy the crap of KK.
[Xperia Z1 General] nikola1970:
Yeah, 4.3 was a lot more stable and battery lasted longer as well.

4.4.2 brings us an improved image quality i have to admit, but camera is so laggy and buggy. -_-
[Xperia Z1 General] dinomovil11:
new bug for me, the camera frozen when take a picture :S
[Xperia Z1 General] Rui Oliveira 21:
I beg to differ with you sir, I find the KK a major plus, in terms of smoothness, performance, overhall stability and even in battery department I have some preety good results, but somtimes the radio signal drains quite a bit of juice but that's mainly to the bad cellular reception in my house, since it's a bit far from the tower.
[Xperia Z1 General] jonmorris:
Today when I fired up the camera, the keyboard came on the screen! I'd been in Messaging before and it seemed to get rather confused. Once I minimised the keyboard, it stuck on a freeze frame of the camera image.

Where is this fix? I need the camera to work, or else I might cut down my SIM and start using the One M8 for a bit.
[Xperia Z1 General] Aegethir:
But then you are one of the lucky few ones, which apparently is not the norm, but the exception with this last update. Which, again, it's not normal.

When most posts in this very long thread, and on Sony's official forums, talk about an almost endless string of encountered bugs, you might not convince others that everything's down to battery being drained by bad reception.

Apparently, a patch will be released to address the sound issue, but hopefully the guys at Sony do realize it's not the only bug, or we're going to have to wait for other patches to patch the last patch.
[Xperia Z1 General] Geoffxx:
I'm beginning to wonder if it is the smartwatch or it's apps that are causing my mediaserver issues
[Xperia Z1 General] Aegethir:
It could be a lead, but I really doubt that all the people having the same bugs over and over have a smartwatch causing all this debacle..
[Xperia Z1 General] palkia171993:

[Xperia Z1 General] Rebel2k:
Thanks for your advice. I just rebooted (it was my first boot after having updated) and it solved it! :)

[Xperia Z1 General] Tizza:
Surprised no one's mentioned it yet...

Bluetooth is a load of s#!t, much worse than before.

I use it in my car, so I only switch it on when I'm driving.

The Bluetooth toggle option now takes longer to get to; a hassle when you just wanna get going.

So, I figure I'd make use of the Quick Throw widget on the lock screen. What a joke! You have to swipe down on the widget to first expand it, then tap on it, then input your screen lock unlock pattern (or equivalent). That then turns on WiFi and Bluetooth, and it searches for your saved paired devices. Seems to take longer to connect, too.

Last time I used it, though, I had to manually select my car for it to connect. When it finally did, I soon realised that for whatever reason my music was playing in order instead of shuffled (via the Walkman app), as I had it when I last played my music (after the update).

Also, whenever a notification came through (from Facebook), the music stopped completely. I had to press the play button on my car twice (as the first time registered as "pausing" the music, even though it had already stopped), and then when the song started playing once more, it was back at the beginning again!

Oh, and when I finish driving now (meaning my car is not running, along with its Bluetooth), the damn music continues to play, making me have to manually turn it off.

Argh. Kinda regretting updating, but it's early days and so I'm hopeful that I can find some workarounds.

[Xperia Z1 General] Handy0:
Thanks for confirming that, but what I really wanted to know fir sure is whether the rooting method had anything to do with keeping root after OTA upgrade, or is it a standard thing that any rooted phone will preserve root after OTA upgrade?

Anyone else had kept root that way?

I'm eager to use OTA but still afraid that I'll lose root and to be honest I don't want to go through the hassle of reseting the phone and reinstalling/restoring everything back!
[Xperia Z1 General] eclyptos:
No one keep Root after OTA.

Don't use it, you will lose Root. To keep root using NUT method and you will just have to spend 5 minutes, same time when using OTA update, so I don't know where is the problem..
[Xperia Z1 General] Geoffxx:
It is worth noting that the recent update to the camera app (V1 Sports) today has again addressed SD Card issues on KK - this is the second time they have attempted to fix something with KK, I am pretty sure there are many more to come with other apps that we are all running on our phones

If people, like me, are having problems with the internal camera, it seems that KitKat has now resulted in me rarely being able to use the QX10 camera either. Keeps dropping the connection, making it useless.
[Xperia Z1 General] Handy0:
But "kgainn" clearly said that he kept root using OTA update. Which means it's possible.

I normally upgrade OTA and preserve root (when possible) but in the same Android versions, still not sure if that would work from Jelly bean to Kitkat!

That's the reason I'm asking if anyone else managed to keep root with OTA upgrade and how!

[Xperia Z1 General] uherrera:
If you have a custom recovery or kernel the OTA upgrade may/will fail. Return those to stock and try again.
[Xperia Z1 General] gregbradley:
There is no such thing as stock recovery. But do not try an OTA with an unlocked boot.
[Xperia Z1 General] RHBH:
I don't know about the recovery part, but as a custom kernel requires an unlocked bootloader, OTA (at least on stock ROMs) will never work.

PC Companion and Sony Update Service also doesn't work with unlocked bootloader. For unlocked bootloader you need use recovery, flashtool, EMMA or OTA (if you're using a custom ROM that supports it) to update your device.
[Xperia Z1 General] Handy0:
Well, I have locked bootloader but that explains a lot. So OTA won't work with this upgrade.

I'll follow the guide mentored in the forum to maintain root with KITKAT.

the only way I can get my Z1 to work properly is to unmount the ext sdcard so this issue is very clearly with googles restriction on access and permissions and some app developers unable to write code that works

We can all roll over and take it up the ass but this situation is completely unacceptable = the money profiling machine called google needs to really rethink what they are trying to do - my device is mine bought and paid for - if I want to use an external memory card that is up to me - if I want to install some software to access that storage - that is up to me

They need to fix this because my Z1 is unusable as it is with F'cking KitKat

[Xperia Z1 General] jonmorris:
Not launching the camera from the shutter button, but unlocking (if necessary) and selecting the camera icon on-screen, seems to be eliminating the problems for me. Otherwise I'd say the camera freezes or gives an error more than 50% of the time (and it seems that the last app you were using might also play a part in whether it freezes).

The other suggestion about storing the photos and video on the internal storage (you can move it later easily by going into Settings/Storage) might also eliminate problems relating to the media server accessing the SD card afterwards, causing the phone to get really hot.
[Xperia Z1 General] nutzuTo:
same problem here, but I went back to 4.3 the camera problem is more annoying than anything
[Xperia Z1 General] Geoffxx:
I have identified 3 hidden services under mediaserver that are causing issues with my ext sdcard which if I unmount my Z1 works perfectly

It seems that mediaserver wants to constantly scan my external sdcard files, I've wiped it clean and copied all my music - photos and video back but still have a problem, I did not have this problem with 4.3

I've also done a fresh install and removed most of the apps that I had downloaded - I use poweramp - mxplayer - and quickpic for media

here are the hidden processes that seem to me called by mediaserver

com.android.providers.media

com.android.providers.downloads

com.sonymobile.storagechecker

one of these three hidden processes is the culprit

I suspect it is the storagechecker service from Sony even though I have reinstalled and wiped the sdcard

maybe someone smarter than me can work this out - I'm at a complete loss
