Another bug.

Connect headphons, play music, call to someone, end call and you will hear your beautyfull song in mono ;) annoying but can live with it. :)
[Sony Xperia Z Ultra] hardtheory:
when rebooting phone, rintones are not saved and are unknow source.
[Sony Xperia Z Ultra] dannejanne:
And you have done a factory reset I assume?

I don't have this bug.

Don't report "bugs" if you have not done a reset.

Tried clearing the apps cache?

Otherwise try navigating to "Android/data" and delete the files "com.sonyericsson.album", "com.sonyericsson.music" and "com.sonyericsson.video".
[Sony Xperia Z Ultra] Unreal988:
i tried but have same error.....

try another galllery but ........... :(

if not another solution reflash with flashtool with all wipe??

or downgrade?? it's possible??
[Sony Xperia Z Ultra] madsponge26:
Try to use Quickpic..
[Sony Xperia Z Ultra] Unreal988:
tried and now it's ok (album).... but.... why quickpic yes.. and album no??? where is the problem???
[Sony Xperia Z Ultra] fastest83:
My album and movies apps work just fine, but I can confirm (over 2 kicks from my wife, awaken by the loud BIIIP BIIIP BIIIP) that the app "alarm" doesn't remember ringtones. That (personally) sucks.

Kitkat update my come restarts alot by it self
[Sony Xperia Z Ultra] JackHanAnLG:
Ive noticed that theres a lot more lag when scrolling opening apps etc, i did the update through PC companion, maybe theres a bug, so ill factory reset, maybe re flash it and see what happens
[Sony Xperia Z Ultra] Cristi95:
i also have problems with it,messages crashes sometimes..
[Sony Xperia Z Ultra] corrado85:
i can confirm that there is NOTHING wrong with the kitkat upgrade. everything is smooth as butter.

wipe all data before upgrade twice, flash 4.4, wipe again. SMOOOOOOOOOTH

stop spreading lies ya'll
[Sony Xperia Z Ultra] droidcruzer:
Actually, each person may have a different experience. I lost signal strength and speed and also lost the ability to use am sms blocker. Yes I know there is a built in blocker, but who wants to modify it all the time? Not me, that's why I liked 3rd party apps , I could create different profiles based on what I was doing. Yes signal speed and strength are subjective, but I still lost performance from MJ4. The AOSP ROMs like carbon seem to give the best strength, but it has poor speed.
[Sony Xperia Z Ultra] mathurmatt:
issue with sd card can't write properly ........ even with root........
[Sony Xperia Z Ultra] dannejanne:
You have to use the built in File Commander since KitKat. This is not a bug. Not Sony to blame but Google. Developers needs to update their apps.

^Thanks for the tip but I have disabled Hangouts and moreover it is not visible in battery monitor. I am facing HUGE battery drain with battery being exhausted within 8-10hrs and phone is always warm (39-43C). The problem has re-occured after a month of stable use. The only thing I could think of was i updated Xposed but even after disabling it, the problem persists.

Camera & Mediaserver seemed to consume chunk of battery so have since disabled camera & have stopped Media using Apps OpsX but no difference yet (Camera has stopped but mediaserver is consuming 54% of battery!). Any help will be much appreciated as I am going on vacation from Sunday and the phone is unusable now.
[Sony Xperia Z Ultra] blueether:
mediaserver could be a corrupt [media] file?
[Sony Xperia Z Ultra] cashif:
Maybe. I formatted and flashed C6802 757 ftf and everything is alright now (Had C6833 ROM in C6802 earlier).

PS: Problem is back again after restart. Battery is working fine when in sleep but once I switch on the screen, I tend to lose 1-2% every minute. I removed the sdcard and tried; it worked fine for few hours but after another restart, the battery drain has again started. Have formatted my 64Gb MMC and reloading data again but this mediaserver drain is killing me.

Thinking of going back to 681!
[Sony Xperia Z Ultra] LordManhattan:
You might have a corrupt file on your SD card, which makes media_scanner go berserk. Pop it out and see if it gets better. If it does, format your SD card and hunt down the corrupted file(s).

Sent from my C6833
[Sony Xperia Z Ultra] cashif:
Have already mentioned in above post that I removed it, it was working fine but after restart, problem restarted. So, formatting Internal/External and trying again!
[Sony Xperia Z Ultra] Lc1975:
I only have one issue until now...

Sounds (calls, sms, etc) it appears to be lower then 4.3...

Using 4.4 HK

Solved my issue..

Just install SDfix from the Play Store. It'll revert the whole SD change from Google, and you'll be able to copy and delete files again.

[Sony Xperia Z Ultra] dannejanne:
I have had two random reboots now on 4.4. The phone just freezes and then reboots after a while. Also there is a sound bug where the speaker volume gets very low occasionally and only reboot restores it. I missed the alarm this morning because of this.

To me, 4.4 seems much more buggy and unstable. Never had a reboot on 4.3. And yes I did a factory reset after update.
[Sony Xperia Z Ultra] manigma:
So can we play games in actual FULL SCREEN mode with SoftKey navigation bar hidden? :confused: Has anyone noticed this change while playing games in ZU 4.4?
[Sony Xperia Z Ultra] Speederoff:
YUp, tested. I play clash of clans in full mode :)
[Sony Xperia Z Ultra] manigma:
That's great. :good: How about other games like Asphalt 8, Dungeon Hunter 4 etc? I am still waiting for 4.4 update on my C6802. :(
[Sony Xperia Z Ultra] madphone:
If games support immersive mode, it will workt. i have tested it with perfect kick for example.
[Sony Xperia Z Ultra] princemarcus19:
Question

so i did a fresh installation on the kitkat update . Everything is smooth so far ,what i notice that i dont have is in the walkman player ,i don't have music unlimited merged ,anyone has music unlimited under walkman .
[Sony Xperia Z Ultra] LordManhattan:
Yup, everything is here, but:

- It lags. Something 4.3 didn't do.

- Had a random reboot an hour ago

- Random UI glitches, especially an icon that blink for like .2 seconds in the statusbar whenever it feels like it.

I did a full wipe.
[Sony Xperia Z Ultra] blueether:
I'm wondering if that is why the 747 build is floating around,a quick update?
[Sony Xperia Z Ultra] LordManhattan:
LOL, I just turned the brightness to max, and now the screen blinks like an old fluorescent light bulb. Fantastic work on this one, Sony...

Funny how I'm starting to hate my Ultra more and more for each day that passes.
[Sony Xperia Z Ultra] sanvara:
The battery is draining noticeably faster when idle with kitkat vs 4.4. I even turned off some extra services like location and wifi scanning that I had left on with 4.3 and it still drains faster when the screen is off. There's got to be a service that kitkat introduced that is sucking battery power.
[Sony Xperia Z Ultra] bryanky5:
For me battery is fine. But yes it does lag more than 4.3. Also twice now this has happened where both my lockscreen and home wallpaper turns completely black and only reappear if you reboot the phone.

Other than that I haven't gotten random reboots or anything. Seems fine besides the lag and the wallpaper thing
[Sony Xperia Z Ultra] LordManhattan:
Yup, i have deleted every single "bloat" app that i don't use, i have disabled Google Now, i have disabled the camera (KitKat bug that makes it run 24/7 in the background), i have no widgets, i have under 10 (3rd party) apps installed, and Stamina enabled with only Gmail whitelisted. I'm lucky if i get 4 hours of screen time on a charge. I got 5-7 hours on Jellybean. I really like the build, but it's just too much crap going on right now, so this won't last long.
[Sony Xperia Z Ultra] herogjan:
Strange, i'm verry satisfied. For me 4.3 was laggy, didn't run as smooth as 4.3. After receiving 4.4 its a lot smoother again. Didn't test walkman, just checked camera and was not active. I did use the camera today.
[Sony Xperia Z Ultra] princemarcus19:
@ lord Manhattan. Am trying to figure out y I don't have it merged in all I have is music effects option
[Sony Xperia Z Ultra] mathurmatt:
Don't know what is wrong with your device mine is running super smooth not on par with 4.3 but you know i have seen dimmer 4.4

don't have any of the issues you mentioned

may be it's your ftf that messing up try using other ftf's ...............
[Sony Xperia Z Ultra] corrado85:
i see no issues with 4,4. its smooth as 4.3 and everything works fine. i even used max brightness while watching netflix, no probem

Hey peeps i cant play songs in walkmen i gt csnnot play song error??

Please help.
[Sony Xperia Z Ultra] dannejanne:
My issues so far (yes I've factory reset);

-more drain in standby. About 5-6% over night where it used to be 2-3%

-2 random reboots so far

-flickering of icons on Homescreen few times

-sound volume lowers to more than half occasionally, missed an alarm because of this. Reboot fixes it.

-stamina mode lets through facebook notifications even though it's not white listed.

Seems much more buggy than 4.3. I've done a second reset now and will keep my eyes open.
[Sony Xperia Z Ultra] southsidejamaicaqueens:
going back

What I really hate is the time it takes to open the multitask function

plus flash player now only works sometimes (worked every time with 4.3)

And When I uninstalled the xperia lwp there was no more sparkling effect or even a lockscreen wallpaper...

So do u recommend going back to 4.3 or wait for the miracle?
[Sony Xperia Z Ultra] princemarcus19:
Yea I might have to reinstall. Phone keeps rebooting randomly
[Sony Xperia Z Ultra] madsponge26:
Exactly. So far no issues here.
[Sony Xperia Z Ultra] fastest83:
Battery drain is a huge letdown, I used to get home with 20/30% left and now I have to pay attention not to use it so much, or I have to charge it in the car.

Secondly, there's been some change for music over bluetooth: SBH52 finally works with no hiccups, but on 4.3 volume was separated, you could set whatever you wanted on the device and tune it on the SBH52; now it's linked, so whatever you choose on either is the same.

Now I'm fine with that, but with a portable speaker (jbl charge) not so much: volume on the device is irrelevant, it always streams at max level, with the result that you have to reach to the speaker to tune it every time. A pain in the freaking are if you ask me.

I also don't like the painfully slow multitasking, it takes from 3 to 5 seconds to open it and that's simply unacceptable.

I guess we'll be seeing a "bug fix" update soon.
[Sony Xperia Z Ultra] helix23:
.681 is a big mess. Flickering icons, massive battery drain and laggy buggy user experience.

I finally returned to .136 again... :(

I am more than disappointed !
[Sony Xperia Z Ultra] zangetsu2188:
kitkat!

This is more of a rant than a bug. hehe. My other phone updated to kitkat shows letter "K" before showing the Android 4.4.2 when you click the android version many times. Our Z ultra shows number "1" when you click it. Attached some screenshots.

Hmmm.
[Sony Xperia Z Ultra] LordManhattan:
Yup, you're right. That's a little strange :p

---------- Post added at 04:11 AM ---------- Previous post was at 03:43 AM ----------

Okay, so I'm lying in bed minding my own business. Cue the chainsaw that is the Ultra's vibrator. It went nuts and I had to do a hard reset to shut it up. Not exactly what I want to do at 4 in the morning.

I've already said it, and I'm saying it again; the Kitkat update is currently the Charlie Sheen of the mobile world. It does a lot of unexplainable stuff, stable as a stripper on crack and then crashes like the Hindenburg when it feels like it - which is pretty darn often.

How did this mess get out the door?

/Rant

Now, back to sleep.

Can not mount system.

I just tried to update .681 by followed this thread http://xdaforums.com/showthread.php?t=2687848&page=7.

I tried to do what skylinestan said, but I can't mount the system in TWRP.

But I can do so with CWM instead.

However, I can't upgrade TWRP version by installing "ZU-lockeddualrecovery2.7.95-BETA.flashable" file.

Does anyone have a good idea to resolve this issue?

I'm sorry for my poor English, I'm Japanese.

There is no such forum like here in Japan at all, thanks for your help.
[Sony Xperia Z Ultra] neverborn:
If that's not working for you, how about trying the FTF file via flashtool? And then just root after you're already on kitkat?

Should be pretty safe.
[Sony Xperia Z Ultra] tsiros:
camera is slower to open/close. can't think of anything else right now. Haven't noticed anything that has been mentioned this far. Oh, and automatic screen rotation takes like 3+ seconds. In 4.3 it was almost instant.

edit: funny... now camera is fast and rotation is fast, but firefox has some scrolling glitching. will reboot and check again :/

edit 2: after a reboot camera opens and closes faster and rotation is as fast as it was in 4.3, but now that i am editing this comment the tikitaka sounds of the keyboard stopped.

it's sad and funny at the same time, we've got quadcore beasts with 2 GB of ram, we've reached version 4.4 but there are still serious usability bugs and issues.

[Sony Xperia Z Ultra] ubertwik:
Cant find fix for this not even factory reset. If i paired my sbh50 which in fine, then open and app wm, slacker or video the volume start at maximum and blows my eardrum. Then i had noticed that the sound becomes muddy accross the freq. I went ahead a used my mini amps {fiio e6 and c&c bh2} with the same result. I wonder if my ears were screwed or the kitkat update screwed xzu.
[Sony Xperia Z Ultra] dannejanne:
No other "fix" than a reboot for me so far. This is an annoying bug as the volume is much lower from the earspeaker and I have missed an alarm because of this.
[Sony Xperia Z Ultra] LordManhattan:
Hmm, just uninstalled Xposed now, so we'll see of it makes any difference through the day.
[Sony Xperia Z Ultra] dbolivar:
How to reproduce this audio bug exactly? I'm using the new firmware without any issues so far, but it could be because I haven't tested this particular scenario. Btw, I have a C6843 (C6833 + digital TV, in Brazil), but using a C6833 Europe FTF, since KK hasn't been released in Brazil yet. Flashed using Flashtool, wiped everything before, using CWM.
[Sony Xperia Z Ultra] stopa10:
Flashed KK after full reset. A serious bug with bluetooth: my Plantronics headset would keep disconnecting and reconnecting again (the Sony smartwatch 2 works ok, though). Battery life was awful. I had to go back to .136, which works flawlessly.
[Sony Xperia Z Ultra] neverborn:
Gravitybox was the culprit for my issues.
[Sony Xperia Z Ultra] LordManhattan:
Thanks for reporting back! The first thing I've noticed after uninstalling Xposed is that my battery life seems a lot better. Haven't noticed any other stuff yet, but I'll report back when or if I find something interesting.
[Sony Xperia Z Ultra] shaolin95:
No issues with my G-Boom or Ant bluetooth and Battery Life so far no different than .136 for me.

Happy with the upgrade aside from performance on benchies not being as good..hurts my ego lol
[Sony Xperia Z Ultra] dannejanne:
My phone just frooze on me again for the third time after my second factory reset on 4.4. Difference this time I can't reboot it. They screen has frozen and no matter what I do the phone will not turn off. It's just totally frozen in time with the screen on where it froze. Holding the power button does nothing. I've held it for like 30 seconds. I will have to wait for the battery to run dry.

Couple this with the daily occuring bug that notifications will start playing in low sound from the earspeaker instead of the bottom speaker and we have the worst Android 4.4 software ever released to any phone. I'm amazed at the lack of quality control over at Sony's. Last firmware it was the sound enhancements bug and now this.
[Sony Xperia Z Ultra] REAVER117:
Ugh, 5 months after the Google release and I get random reboots, crashes while texting and no ART. Thanks Sony...
[Sony Xperia Z Ultra] LordManhattan:
Hint: Hold POWER + VOL UP for 3 seconds. You'll feel three vibrations and it'll be off.

---------- Post added at 07:34 PM ---------- Previous post was at 07:32 PM ----------

ART is currently only meant for experimentation. Sony will switch over to ART themselves when it's ready, which will probably be in Android 4.5/5.0 according to the AOSP sources.
[Sony Xperia Z Ultra] REAVER117:
Yeah, I know it's experimental, I still want to complain because the XZU will never see 4.5/5.0 and all I want is ART and a working FM radio!
[Sony Xperia Z Ultra] dannejanne:
Thanks a lot! That did the trick. Muchos gracias.

I'm going back to 4.3.
[Sony Xperia Z Ultra] LordManhattan:
Sure it'll see 4.5/5.0. The Xperia Z and that generation is getting KitKat after all. I guess it'll take some time before we get the Sony build, but don't forget that we have the awesome GPe Ultra, which means that we'll get 4.5/5.0 only a couple of days after its release.
[Sony Xperia Z Ultra] LordManhattan:
Alrighty, i've used 4.4 for about a day after uninstalling Xposed. One thing I can conclude is that the battery is much better, so keep that in mind if you're experiencing poor battery life.

Headphone jack port issue

anyone here got issue with headphone jack issue?? the headphone port recognize just the first time you plug the jack.. after you pull the jack and try to plug again.. my phone doesnt recognize my headphone. try to play music with walkman and sound out from loudspeaker, not from the headphone. any idea??? :rolleyes:

No problems here, tried Walkman and deezer, I do have the Klipsch app installed for my headphones though?

Just for info, I installed KK via OTA

I had a random reboot day two running 4.4.2. But since then its been fine (5 days)

Could be because I'm Pro!

I have the same problem too but on second try it works fine, after i change the ringtone with different ringtone picker app (IIRC Media Storage one?).

Camera Quality, it's still the same mess as before, Nothing got improved. But still sufficient i guess.

Battery wise, haven't tried from 100%, charging now..
[Sony Xperia Z Ultra] tsiros:
found another one... very silly, but i noticed something. Remember the 'tick' sound when you tap stuff on screen? yeah, the volume is inconsistent. press the home softbutton once evry second. now stop, wait like 4 seconds and tap again... volume is slightly lower. Which means: if you had tapped the screen and produced the tap sound not longer than about two seconds ago it will make normal loudness. If it has been more than 2 seconds, the lower volume tick sound.

i suspect it's closing the soundcard output to save energy but upon waking up it doesn't get to the correct volume immediately?
