I could not agree more. Runs fast and smooth, increased battery life, improved functionality and no bugs whatsoever, I can honestly not understand why some people reported issues with the camera. Thank you Sony, this feels like a new phone! I am so glad I bought this and no other.
[Xperia Z1 General] Vengeance66:
After some use of the new 4.4 update I noticed many bugs, like never before. I really like the new design, it's modern and very artistic.

I noticed that if I use the Air theme with Live wallpaper, bugs appear and the phone lags. I got black wallpaper and lock screen wallpaper, I got the Waterproof notice inside my wallpaper etc.

The sound problem is at my place too! Sometimes when it rings it comes out the upper speaker, not the speaker below (where it should be).

Overheating and battery drain are also said from many others.

But, the one that worries me is that the camera crashed three times in a row today. I'm scared to use it, I don't want to lose the camera. I always took photos with it. I noticed improvements in the camera, but now the ISO implements after the photo is taken, not real time like before. I don't like that...

I hope that there will be bug fixing update. :)
[Xperia Z1 General] jonmorris:
I reported problems with the camera because I had/have problems with the camera. And I can't be alone. So I think it's unfair to say that because you've not had problems, everyone who says they do is looked upon as being totally wrong.

It now quite often fails to start up, and I get this;

View attachment 2654370

or it starts and freezes on the image it first sees, and then quits to the lock screen or the camera not available error.

It's happened before on other Sony models, but not recently. I hope Sony knows exactly what the problem is and has already fixed it for the next update. Just as it fixed the problem on an earlier ROM that saw the phone reboot multiple times per day (but you wouldn't always notice as resets skip the PIN code entry).

But, other than the camera problem, and having let it sort itself out in terms of going through my media (I have maybe 6,000+ photos on the SD card, and 200 videos (fairly low quality episodes of Family Guy, Simpsons etc) I will say that the battery has sorted itself out. It doesn't run hot, and like you, I am getting very minimal battery drain now.

In fact, 11 minutes 54 second per 1% drop is my current average - or 14 hours 50 minutes average battery life. And I use the phone pretty heavily, albeit mostly using the camera, Tapatalk or the web. I haven't been playing many games of late - no time.

For the most part, I'm happy. When the camera crashes, it usually works the next time - so the only problem is missing spontaneous camera moments.
[Xperia Z1 General] Luhccas-X10:
One important thing to me is the sound through earphones.

And finally i'm very satisfied with this update!

I feel the sound warmer as i like and clearer too.

There are improvements on soundstage too, the stereo crosstalk has decreased a lot i think.

Using high amperage headphones are a pleasure now.

I'm in love with my AKGs again.

And of course, with my Z1!

Nice work Sony!

[Xperia Z1 General] ckchan08:
i had this problem b4 also and after factory reset, problem solved
[Xperia Z1 General] kantk20111:
I agree, definitely noticed a difference in headphone sound quality as well. It's a lot clearer! And a bit better bass too.
[Xperia Z1 General] ssj_jaypee:
can you post which 4.4 firmware you are using and possible link?

I'm currently using the journalist version and have the camera bug as well as Bluetooth problems still.
[Xperia Z1 General] lukegewing:
I am also having some of the same random bugs.. Camera crashes upon opening, camera freezes after pressing the shutter button. My "autorotate" feature stopped working /crashed. Chrome has crashed. Even my settings "app" crashed. Rebooting temporarily solves all these issues though, so I'm content to wait for the next update, while my wife would rather wait to upgrade.

Battery life seems to drain more but I'm not positive about that.

I do think there is much less noise in the pictures! So that's a plus.

My touch screen response seems to have gotten worse.

I can't speak for the sound issues, as i usually just listen through headphones, and haven't paid that much attention to notification sounds.

I'm just surprised there's so many bugs, as the last two systems seemed to be rock solid. Overall i don't see a compelling reason to upgrade other than the better picture quality, if you can stand the constant bugs.
[Xperia Z1 General] timberwolf60:
To rectified the sound came from the earpiece, tried run Google play music on any song. Then quit play music. Run YouTube, MX player and the problems solved. This tip was encountered by someone posted in the forum. I tested it and even after reboot, it still worked for me. I had no camera, bluethooth, wifi problems on my phone. My phone was rooted and run sdfix so I had no external sd card problems. Battery good as 4.3.

Z1 KK - Great Battery Life

Would just like to share what great battery experience I have with the KK update :)

Total ScreenOnTime is more or less 5hours, with some GPS activities, always connected to data, either via WIFI or Mobile Data
[Xperia Z1 General] MakaMika:
Am i the only one who's still waiting for kitkat? O.o
[Xperia Z1 General] Johneboy:
I get the volume inconsistencies just like you do. The bluetooth signal is weak on this phone, just like the WiFi when compared to other handsets I've used and this is what I believe is causing the stuttering in playback.

Anybody noticed the quickboot mode in developer options?? I can't power off with it enabled....
[Xperia Z1 General] chunlianghere:

hi

i can't sync contact with my exchange Outlook.com account

[Xperia Z1 General] gregbradley:
Just flash any UK ftf, it will be exactly the same except have some branded apps on it.

You can delete them using Titanium if you want, or when the UK unbranded FTF becomes available, just flash that. In the meantime you will be on 4.4....
[Xperia Z1 General] depperly:
I have to say that I have had no issues with KitKat. I did my update through the Companion app and have been happy ever since. My battery life went up all my bluetooth issues went away.

I have been very happy with the update.
[Xperia Z1 General] MohammadAG:
With the Z2 sources out, I decided to take another look at tap to unlock.

The sources were completely useless, the panel is different, and the gesture used doesn't exist in the Z1's panel.

With that said, I tried to make it work manually, and it did!

I'll release it soon, here's a preview though https://www.youtube.com/watch?v=FOfKtxbsjqY

Release it soon mate.... Let's throw this in sony's face.... Soon we'll have timeshift too I believe....

is there any fix for Z1 for the sound problem i get sound from the ear speaker got some missed calls becouse it was ringing from the ear speaker

my phone is 100% stock no root and locked boot loader

Looking forward to tap2wake!

Go to the thread possible fix for sound someone is testing a way of fixing it look at the last comment
[Xperia Z1 General] ascariss:
One issue the camera on my end, starts up very slowly compared to the 4.3, probably mentioned on here. Start from shutter key is hit and miss, sometimes starts, other times it crashes. There are some times when the IU has a hiccup, and isn't smooth. The issue I had with the dock is still there, where I unlock the device in the dock, leave it, screen turns off. Then after a second or 2, screen turns on in portrait mode and then resets into landscape, all while in dock. This also happened in 4.3.

There's a reason why a new firmware is already testing, some bugs still left.
[Xperia Z1 General] fl4r3:
Genius!

Will this be an add on for rooted roms or is it going to be a modified kernel?
[Xperia Z1 General] IAmCowGodMoo:
What is the safest and most reliable TFT to flash on my Z1?

Im in UK and am unbranded, and have not received the update, and it will probably be weeks to month before we do.

Thanks.
[Xperia Z1 General] timberwolf60:
Listening a song by Google play music, quit. Sound will be out from bottom speaker when I play YouTube, mx player, tubemate since yesterday and remained after a reboot. Try it and enjoy.

i have got a battery drain since i updated to 4.4. When my device is in stand-by mode, it is still consuming a lot of battery. I can't figure out which app i doing that, but 'android-system' is consuming 10% of battery. Could a factory reset help?
[Xperia Z1 General] eclyptos:
Yes.
[Xperia Z1 General] dakunclear:
To some extent some times getting ppc to do a repair is the best thing you can do bit even then it's still glitchy as hell
[Xperia Z1 General] AndroidDan:
Yes ove noticed that I tried to test it all but that doesnt seem to do anything except stop the power off so therefore it doesnt even boot so quickboot dont work lol weird one really
[Xperia Z1 General] eclyptos:
Actually I always advice to do a Factory Reset first, then if this not help that mean the system can be corrupted, in this case then, yes, repair via PCC is the best thing. This 2 factors, Factory Reset and Repair via PCC, are completely different.

hi guys, found a bug or spy cam on the playstation app,when i open the app and browes its cool but when i exit the app my cam is on and active for a few seconds, then goes back to my home page, anyone else found this issue, regards joe, when i say spy cam its me being parra, or is it a bug, this is somthing i found on my device so dont slam the messenger,cool
[Xperia Z1 General] eclyptos:
They are looking at YOU! :cyclops:

Maybe a funny developer want to see you face when you play on playstation! ..hahah..:D

I don't know, you should check if when you using that app there is a network Connection going out...it mean something going out from your phone when playing.

Just to be a bit parra..;)
[Xperia Z1 General] joecool666:

maybe someone with a bit more knowlage than me could look into this matter, yeah there is a connection going out, big brother is wacthing us lol,

Did you update Officially through your network? OR did you flash a TFT file?, if you did flash could you tell me which one, as im unbranded in the UK, and have not received an update, so looking to flash one.

is anyone having the screen going darker with prolonged use, my screen dims about as much as 50% if I'm playing a board game or card game for more than say 20 mins, my guess is it is some sort of battery management thing which I don't want, I want the brightness to remain at the setting I want, it's a bit like the auto backlight feature that was removed from settings after it cause some boot issues, there were no issues in 4.3 with this
[Xperia Z1 General] negrobembon:
That's hasn't happened to me(yet)

Yesterday i played Rayman Fiesta Run for 2 hours, with like,75% brightness and it never dimmed, it didn't even get warm

Though RFR is hardly a demanding game
[Xperia Z1 General] timberwolf60:
Try removed ext sd card if still high then do a factory reset. Also you can run rescan media.

i have the problem that there is an icon poppin up in my statusbar. I think that it is the settings icon. That might cause the battery drain. Anyone else have this?
[Xperia Z1 General] gregbradley:
An icon will not cause battery drain....
[Xperia Z1 General] migidid:
Okkay... Now i have used it a while and verry smooth like i said and amazing battery life but couple times it opens an last app when i go home, like phone or something when i check the time... just randomly and not much... and i have been hearing that sound bug like 2 times so not much. So i think we all have them but randomly, and its up to sony to fix them...
[Xperia Z1 General] ikkeeuu:
yeah i know, but that thing is likely to start in the background. I think that is the one causing the battery drain. Also "Android-system" is taking up 15 percent of my battery.
[Xperia Z1 General] MohammadAG:
The icon keeps showing every couple of seconds, so the underlying process can cause drain.

It's a "Remote Shares" notification if you're wondering, I haven't checked what it says though.
[Xperia Z1 General] gregbradley:
Yes, but he asked about the icon

I use remote shares but I don't have an icon for it. However, I have turned off most status bar / notifications icons in settings
[Xperia Z1 General] MohammadAG:
It shows for less than half a second.

I logged notifications with an accessibility app, it's the 4.3+ notification for services running without a notification.

"Remote shares is running, touch for more information or stop the app"

If you want to reproduce this, toggle Wi-Fi off and on, when you're connected, stare at the top left corner for a while, you'll see it.
[Xperia Z1 General] gregbradley:
No, don't see it....

I am connected to my remote share (2 in fact) and if I toggle wifi I don't get any notification in the status bar.

But I have blocked android system from the notification bar in settings/personalisation/manage notifications
[Xperia Z1 General] orvil:
No full screen album art

i am happy with the update, z1 runs smooth and i haven't experienced any kind of problems. the only thing bugging me is the full screen album art in your lockscreen when playing music, which was one of the reason i said WOW to kitkat. nexus, galaxy they got this feature as well, but in xperia it dosent work for some weird reason! i also hate the new unlock animation, is there any way i can use the 4.3 blind effect to unlock my phone ?
[Xperia Z1 General] Handy0:
Now that's interesting. So does this mean OTA will maintain root?

I have 4.3 rooted (can't recall which method I used though) but if I do OTA upgrade then I can keep root?

Thanks
[Xperia Z1 General] kgiann:
OTA upgrade is the best

It has kept root for me the way I described. Generally speaking upgrading OTA preserves root. I only upgrade OTA if available. It usually comes out later than the PC upgrade (using PC companion). It worths the wait though as it allows time for research and planning the new upgrade / root, so that one can avoid the pitfalls and problems others had.

My experience from KK has been a great one. No problems whatsoever!

However, I only use applications from the market, official OTA upgrades and root with Kingo android. I would also encourage you to have busybox and SDmaid as they really speed up the OS.

Best of luck!
[Xperia Z1 General] jonmorris:
I'm really rather annoyed with the Z1 today.

Went to see my son at football class for the first time, and after having to wait for it to go through the camera not available nonsense (this was from using the camera button from standby, which initially just took me to the lock screen and THEN the camera) I managed to get a few photos, until;

View attachment 2658680

And, yup, the phone was hot. Hot enough that while I left it to cool down, it actually took about 15-20% off the battery - so I turned the phone off.

No more photos or video!

I am starting to think the problem lies mostly with starting the camera using the camera button. Sony must have messed up the quick launch feature, but what is causing the phone to suddenly go red hot is beyond me. All I did different was take a lot of photos in quick succession, but it's not as if that's caused problems before.

And, no, it wasn't a warm environment. It was indoors too, so the phone wasn't sitting in the sun.

Edit: here are some stats showing the huge drop, and my average battery life is way down on what it was pre 4.4, including average time per 1% drop. The time to charge is also way up.

This update is doing my head in, nothing but trouble from the word go

Updated via PCC

Media server is causing all sorts of problems I thought I had it fixed but no

Wiped phone did a repair through PCC and no better, the only thing that fixes the problem is to unmount my ext sdcard

Have read on many forums on all makes of devices having the same issues as far back as Feb

currently now wiping my sdcard and reformat, it contains music photos videos a few office files and that's it but is 40gb, if that doesn't fix it then I'm going back to 4.3

Don't know if it's a kitkat problem or Sony problem but it is a serious problem either way

Have been looking for something that will tell me what app is actually using mediaserver but can not find anything that does this, I've killed apps uninstalled apps disabled almost everything and it is still there, my phone heats up and is flagged by a monitor app that the battery is overheating and mediaserver is using 50% cpu which means there is something drawing a huge amount of power/current from the battery so much so that if I don't unmont the sdcard before charging the charger doesn't have enough power to charge the phone

extremely annoyed with this

4.3 was stable with no issues - I suspect something keeps trying to access the sdcard but is being blocked but continues to try creating a huge drain
[Xperia Z1 General] DonutCommander:
Last night I was having overheat with only downloading apps with WiFi activated

[Xperia Z1 General] jonmorris:
It's a joke isn't it!

And this time around I wiped everything and, thanks to the backup tool not working, had to reinstall everything from scratch - so it was basically as if I'd taken the phone out of the box brand new.

Thing is, if whatever causes the problems doesn't happen, the battery life is pretty stunning with 4.4. Of course, it's always going to feel like a gamble at the moment. Will it last all day and into the night, or get hot for 'no reason' and be dead in a few hours?
[Xperia Z1 General] chunlianghere:
back here to report back tat after flashing only baseband from 257, the problem of sound stuttering and volume inconsistent is gone.

so for those who is having the same problem as mine, do test to flash baseband only from 14.1.G.2.257. hope it helps..:D
[Xperia Z1 General] BLiapis:
My volume can't b considered adequate by any means. I miss MonX rom and closed framework already. Battery is not stunning or anything asleep. Feels the same.
[Xperia Z1 General] Valforte:
I found a workaround for the sound coming out from the wrong source...

Just open and close the task manager and the sound will start going out from the correct speaker.

This is not heavily tested as this problem only happen for me with one game (the only one that I play), the sound sometimes comes from internal top speaker, doing this revert to the internal bottom speaker.

Using NUT rom with Root and LB.

Don't know if this was already posted, sorry if it was!

Can someone tell me WTF is going on with the UK update because with the update checker most of the countries have the update apart from unbranded UK. I want to keep the phone with the full warranty and I am waiting for a proper update but it doesn't seem to come to UK.
[Xperia Z1 General] BLiapis:
You ain't missing out a thing. Stick with the previous release and it's as good. Although manually updating to an official release of another local, won't void your insurance.
[Xperia Z1 General] mnsk:
As compared to JB I am seeing fast battery drain, more ram consumption and overheating in KK.

Also don't forget the sound bug. :(
[Xperia Z1 General] CamilleKills:
I know you guys but it isn't the case for everyone... So maby I will be lucky enough to dont have all of that bugs and honestly the anticipation is killing me now...
[Xperia Z1 General] jonmorris:
Possibly, and as every day goes by we hopefully get closer to the updated version that will presumably fix all the issues anyway.

Just this evening I've been on the phone using Chrome and noticed it was getting hot again.

The battery is fine until something goes wrong in the background and it gets red hot; then kiss goodbye to your battery life (and if it gets too hot, perhaps damaging the battery permanently too).
[Xperia Z1 General] rmyc:
is there a good guide on doing an OEM downgrade? and which version is working?
[Xperia Z1 General] Geoffxx:
I now seem to have a stable device since doing this, I also uninstalled all games from my phone and deleted all .nomedia files from my ext sdcard

Even with all the above I honestly believe that there are a lot of apps out there that do not work and cause problems with KK, as the days go by I keep seeing apps being updated on my phone and the primary reason is KK compatibility, it's reaching the stage for me were unless an app actually says it is compatible with KK I'm removing it from my phone
[Xperia Z1 General] T_L_O_T_D:
Is it worth to uptade to kk or it's still buggy and we should wait for another update? Should i update it via PCC or we will get it from update center?
[Xperia Z1 General] cippi21:
I think you should wait it's still pretty buggy...camera and sound issues are the most common...also some people reported overheating and battery drain issues....
