System and user apps are storing data during your day-to-day use of the phone. After a "firmware" upgrade - which is essentially an Operating System upgrade, it is more than likely that every application has been upgraded also. So the old data and settings (which may have an another - old format) may interfere with your fresh OS and apps. These differences are often not handled by the upgrade process, so it is highly advisable to start from scratch and erease all old rubbish data and settings.

It is like when you move to a new house, you probably have to relearn the place of every appliance and corner instead of trying to find the toilet to the left (which is now the kitchen btw.).

Instead of wasting your time with all these "phantom" bugs, you should do a factory reset and quickly reconfigure your phone. You could also learn some new stuff about the your new OS during this process, and avoid flooding these threads with bugs that are only existing because you don't have +1 hour to spend a little time with your phone, but you do have +x (x > 1) hours to write to these threads complaining about phantoms.
[Xperia Z1 Compact General] Nos0x:
If it's been coded properly all of these scenarios should be taken into account. I've done numerous Windows phone, iOS updates on the many devices I've had without this being a requirement.

---------- Post added at 07:51 PM ---------- Previous post was at 07:49 PM ----------

Btw, new bug, call log is not showing (and I've already tried a factory reset before anyone chimes in with that).
[Xperia Z1 Compact General] vetko:
I didn't say you won't have any bugs, I just said that you will have probably far less :).

And I do agree, they could have been coded that way to migrate all the system settings and data to the new OS (but even in this case, they can't do this for user installed apps). It is clearly not having the same swiss-watch precision as Apple manages to deliver in majority of cases, but this is Android, a much-more liberal and customizable OS, and this is why we (I at least) love it. It don't bothers me if I have to reinstall and reconfigure my stuff once in 1-2 years if I know that I will have an updated OS and fresh experience afterwards.

Remember guys that sdcard write problem is caused by kitkat change/google. It is happening for all OEM, not just sony specific,

Edit: To be clear. google made the change, OEM might revert/skip it. In this case sony didn't. There is a rumor that in the future this is mandated by google and shouldn't be removed.

ps: Data up to post #109
[Xperia Z1 Compact General] Woodyxps:
Well, I still have my Samsung S4 with Kitkat and sdcard write problem does not exist in it as bad as in sony. In S4 I am able to write to sd card by quick pic but not in sony.
[Xperia Z1 Compact General] _katho_:
Then Samsung doesn't adhere to the Kitkat specs so have nothing to do with Z1 Compact.

It's actually good as a security thing.

Sony Update Service
[Xperia Z1 Compact General] SirRobin78:
Yes, i can confirm this thing - and the playmemories online part is also missing in album app, i know that there are big maintanance updates on playmemories but the shortcut must be in the app or not? I can confirm that this also is on Z1 devices after whipe. FW update left the playmemories part still available...
[Xperia Z1 Compact General] profyler:
"Stuttering notification sound"

i have this too, and i made a fresh instalation of KK when i've updated android (that mean: hard reset -> KK install -> hard reset again).

Rebooting didnt solve...

How you guyz fixed it with a reboot is unknown to me...
[Xperia Z1 Compact General] SirRobin78:
Yeah, there are a lot of little bugs in this FW across the devices Z1-Z1c-Z Ultra...

Let´s hope for fast bugfix update, things like missing calls or overheating is not really a nice feature :)
[Xperia Z1 Compact General] Gikey1:
Another thing is missing with this update.

There is no 'automatic conversion of special characters in text messages' option. It was very useful to stay with 160-characters-long text messages, there was no need to pay attention if any special character was being used.

[Xperia Z1 Compact General] profyler:
its incredible, doesnt sony test their god damn phone? some bugs here are so easily reproduceable that i believe they dont make tests at all

by the way "Missed call not showing in log", wich log are you guyz meaning? i missed a call yesterday and its showing me when i open the dial screen.
[Xperia Z1 Compact General] Nos0x:
I actually meant that no calls are showing in my recent call log, no made/received/missed calls show at all...
[Xperia Z1 Compact General] Kess78:
Slide down slowly the notification bar starting from the right of it where quick settings should be written and the notification pannel will directly open in the quick settings tab.

You can also slide with two fingers but it's less convenient.
[Xperia Z1 Compact General] profyler:
Hmm i dont have this.. Calls are showing fine

It seams that Hard reset is completely mandatory after this update.
[Xperia Z1 Compact General] bananaman182:
Flashed Kitkat and went back to jelly bean shortly after. Reasons:

- Occasionally unresponsive, laggy performance

- No gapless playback on any players at all. Previously the Walkman app didn't support gapless, but other third party apps did. Those same third party apps on kitkat don't have gapless playback anymore. Although, this doesn't seem to be a problem for most people.
[Xperia Z1 Compact General] nizarnoor:
I notice the loudspeaker has become louder. Good.

But I also have that stuttering notification sound bug. It doesn't bother that much though.
[Xperia Z1 Compact General] Nos0x:
I already did that.

New bug! Today while on a phonecall the call cut out, and when I looked at the phone I found it was because the Z1c had decided to put itself into airplane mode (battery was at 92%, so it wasn't a power saving thing). Really starting to regret buying another Android phone now...
[Xperia Z1 Compact General] shysparrow:
It's all about bugs, this is why we are all here reporting. Its just an bad/incomplete update, I don't understand why did SONY skipped two announced update and jumped directly on KK.

The ROM is so annoying that u literally hated Android. But, I still like SONY handsets & I'm sure our XDA friends will cook something for us soon! :good:
[Xperia Z1 Compact General] sander151187:
That's possibly a feature! I can remember activating a switch for that. If the signal is poor, it switches to airplane mode to save battery. Can't remember if it was a Sony feature or a third party app. Try searching for it.
[Xperia Z1 Compact General] toxic_garden:
perhaps it would help if everyone who commits a bug also tells if he/she did a dirty flash or full wipe. I for myself did a full wipe and experienced none of these problems after 1,5 days of usage. Only thing is that Gravity Box doesn't seem to play well with Xperia KK. Using the volume keys instantly FCes the current app. After uninstalling Gravity Box, everything went back to normal.
[Xperia Z1 Compact General] profyler:
i also made a full wipe of KK

i only have one bug till now, and its the cracking notification sound . its bad but i can live with that untill a fix comes.
[Xperia Z1 Compact General] spinz78:
Crackling sound a little before Notification Sound...Ringer is OK
[Xperia Z1 Compact General] hekermeker:
Kitkat.Full wipe. After missed call it switches to camera, panorama mode.And it remains open, eating the battery in approx. 3 hours. Crackling sound. Battery time poorer than with jb. And lastly, sorry Sony, but this is my first and last phone I'm buying from you. For 500 eur, this is a crappy phone.

[Xperia Z1 Compact General] Nos0x:
I've installed an alternative dialler, and the call log works perfectly in that so the default app is misbehaving.
[Xperia Z1 Compact General] Arthur Hucksake:
Battery life is noticeably worse.

Poor update really. Going to roll back.
[Xperia Z1 Compact General] Nos0x:
Oddly the battery life (for me) is one of the good things about this firmware.
[Xperia Z1 Compact General] sinple:
Some time my notification shade would stuck half way
[Xperia Z1 Compact General] DiederikC:
I'm also noticing worse battery , cani just flash the old ftf? To go back to jb?
[Xperia Z1 Compact General] shysparrow:
Yes u can. I'm already back on Root JB
[Xperia Z1 Compact General] spinz78:
I flashed with Nordic Generic with full wipe and I got a different data icon...

[Xperia Z1 Compact General] bigxie:
For those experiencing performance issues, if you're rooted, you can try changing the governor to interactive. It seems to have helped with stuttering in some games I play and the battery life remains pretty much the same (most time still spent in 300 and 1190MHz).
[Xperia Z1 Compact General] profyler:
battery is exact the same for me (full wipe KK instalation).

realracing 3 seemed to be more laggy somehow :rolleyes:
[Xperia Z1 Compact General] nism0o:
Does someone heave a solution for the call log not showing? heave tried hard reset and flashed 3-4 different ftf files...
[Xperia Z1 Compact General] Enrico2828:
I second that. It seems only to happen when using middle control button - instead of pausing / resuming / jumping properly it would switch to speakerphone .. did not do this with 4.3 as far as I can tell.
[Xperia Z1 Compact General] Gikey1:
Next annoying thing I have found.

You know 'reject a call with a text message' function. It was, simple, fast and easy to use.

In 4.3 JB if somebody calls you could just easly slide up a 'reject a call with a text message' menu with a list of text messges prepared earlier and choose one - fast and easy.

But not anymore, at least it is not fast anymore.

Now, you can slide up a 'reject a call with a text message' menu and you won't get a list of text messages but ONLY ONE OPTION to choose. Guess what option. The option is: 'reject a call with a text message'. If you choose this only option you finally get menu with text messages.

WOW. What an incredible, comfortable and creative change.

I think they could easily add two more steps with a question: "Are you sure you want to reject a call with a text message?", don't you think? :eek:

I would really like to know the way which led to this bright solution.
[Xperia Z1 Compact General] crazyscow:
volume doesnt work when playing music over bluetooth, but thats a normal google problem. they never really managed to do anything with bluetooth, been experiencing problems since gingerbread...they never learn :(
[Xperia Z1 Compact General] ghtop:
My volume keys work fine when using bluetooth, so I'm not sure what you mean. The implementation is different than with JB, though - phone bluetooth and device bluetooth volumes are now linked, so change voiume on one and the value is also set on the other, rather than each having separate values. Maybe that's what you mean by "doesn't work"?
[Xperia Z1 Compact General] Nos0x:
Clearing the call log seems to have worked for me as kahvel mentioned a few posts up.
[Xperia Z1 Compact General] kanefan67:
Found two more bugs using spotify.

First is I tried to use smart connect to start spotify when headphone is plugged in. Deleted all pre-defined actions, to be sure they do not interfere.

When I add start spotify and play track to the headphone plug in. Spotify pops up, but in stead of spotify, the walkman app starts playing the last track I listened to via the walkman app. Last action triggers the walkman app to play, not spotify.

Another issue during spotify playback is when an email comes in, the notification sound is played and spotify is paused and does not resume.

This is only the case with email sound. Whatsapp message sound does not stop spotify from playing.

Another battery consuming bug I found is with Endomondo. After use of Endomondo it is not properly closed. Results in the fact that the GPS remains active using about 10% overnight last night.
[Xperia Z1 Compact General] davidd6:
hello

for me the gps bug appear too.

but with maps, i almost only use location with maps.

and i notice that all night gps was still active in the battery menu, but location was disable.

only with a reboot og thr phone, gps turn off.
[Xperia Z1 Compact General] phantomEVO:
i hate to use two fingers to see quick toggle!!!!! i want the oldest mode with one finger for notification and toggle!!
[Xperia Z1 Compact General] sachilleas:
Sound outputing to Ear-Piece instead of external speaker on notifications , songs , videos etc is lame. It has happened to me too and everytime I need to restart the phone. Happens to z1 also : http://xdaforums.com/showthread.php?t=2692313

:good: Well done Sony for the unfinished firmware.
[Xperia Z1 Compact General] Funkym0nkey:
Ok. So most of my freezing issues went away after factory reset. Still cannot stand how slow the stock Sony launcher feels. Switched to nova launcher prime and all is good.

Sony should have done better job of testing an update on already running devices. Factory reset is fine and all for most people here, but I won't hear and end of it from few friends I managed to convert to android thanks to this phone. For them, these bugs after ota update are unacceptable.

From my Xperia Z1 Compact, in your face!
[Xperia Z1 Compact General] Brewn:
You can still directly access quick settings with one finger. Just slide your finger down a little bit on the right and leave it on the quick settings button for half a second, then pull down - voila. Btw, you can now hold your finger on an icon in the toggles menu to jump to the settings as well. Very handy! I think it's definitely different, but it's also much more functional...
[Xperia Z1 Compact General] kind3r:
I think this is a bug not a feature :P
[Xperia Z1 Compact General] nism0o:
I dont heave the option to clear my call log when its empty?
[Xperia Z1 Compact General] Funkym0nkey:
One bug after factory reset. After restoring app data with helium, noticed that the sound was screwed up. Screen taps were Ok. But the volume of music and media was tiny. Almost as if it was at 1% or something. Fixed itself after reboot.

From my Xperia Z1 Compact, in your face!
[Xperia Z1 Compact General] Nos0x:
It took some messing about in the phone app but eventually I found it. To be clear my call log wasn't empty, just the default phone app couldn't see it (other dialler apps could, so another missed bug by Sony).
[Xperia Z1 Compact General] carlinobg:
after update I'm not able to delete pictures! To be more precise: in quickpic pictures seems to get deleted but they come back after some time.

Same prictures are not present in Sony gallery!
[Xperia Z1 Compact General] poolmaker:
From micro sd card?

Then if you rooted check this thread.
[Xperia Z1 Compact General] slick2404:
Same. After the first flash, it was very choppy and apps using the camera like instagram and snapchat would crash very easily. After a factory reset, I flashed the UK unbranded ftf and it's a lot better. Still not sure about the battery yet, seems like its draining a bit quicker than jellybean.

I also had this problem, again with instagram and snapchat. After a reset and flash it was fixed.
[Xperia Z1 Compact General] carlinobg:
not rooted yet!

anyway thanks for your help
[Xperia Z1 Compact General] profyler:
well, after reading this 15 pages long thread im convinced that a hard reset is mandatory for not having any strange issues after KK update.

(that doesnt mean all bugs are gone after a hard reset , i myself have the stuttering notification sound bug, but at least i dont have many other bugs that people are complaining about)
[Xperia Z1 Compact General] crazyscow:
i had this problem with my gnex and my asus nexus 7 (2012). it might be my logitech UE speaker then. I mean i see the bluetooth volume pop up but if i make the volume go up or down it doesnt change on my speaker. i did a hard reset, but as long as thats the only problem im okay with it.
[Xperia Z1 Compact General] neoxkid:
When I tried to restore with helium the notification led stopped working till factory reset
[Xperia Z1 Compact General] phantomEVO:
yes it is a bug not a feature. ...

i have also an horrible sound bug for notification.

the sound is very low even if the volume is at max!!!

i would like to come back as soon as possible to 4.3!!! how can i do that without losing anything? which is the last firmware before kitkat? (i'm italian with a ITA PHONE). Were can i download the firmware?
[Xperia Z1 Compact General] relsinga:
I can confirm the stuttering notification sound.

As posted in http://xdaforums.com/showthread.php?t=2692156 :

On JellyBean I had the location settings on Wifi+GSM networks, since GPS takes battery power and I don;t need a very accurate location. On KitKat, Google can't find my location anymore, so it seems. On Wifi/GSM Google Maps prompts "waiting for location", on GPS/Wifi/GSM is finds my location eventually but only by GPS location. No GPS reception, no location update.

Is there something broken here?

I'm running a stock EU Z1 compact, no root, no custom ROM or anything.
[Xperia Z1 Compact General] RobHands:
Batterywise the experience so far has been quite sh**** like on all Kit Kat devices. Really disappointed how Kit Kat turned out overall. I'm going to roll back to JB.
[Xperia Z1 Compact General] shuby1001:
Hi,

I have the same problem with the sound going to the earpiece. When playing previews through the playstore it sometimes helps clicking on something in the store while playing the music. That seems to fix it for that particular session.

Hello!

My phone received OTA update with 4.4.2 couple of days ago and i've noticed 2 bugs, one them remains from 4.3 and another one is new for me:

1) The proximity sensor doesn't work properly in case when I'm talking with someone and 2nd call is coming. I take the phone off the ear to see who's calling and the screen turns on as expected but then I get the phone back to the ear to contine talking the screen doesn't turn off until 2nd call is dropped.

2) I have corporate Exchange account with security politics. For mobile devices it's necessary to have either 4-digit pin-code or normal password consisting of letters, digits and special symbols. Of course I use 4-digit pin-code on all my phones. Next day after the update to 4.4.2 the phone asked to improve security for this account and it was possible only to set normal password, the option for pin-code became unavailable. Our IT guys said that they didn't change anything on their side, all other devices like iphones and windows phones work as normal. Reinstalling this exchange account didn't help...
[Xperia Z1 Compact General] profyler:

2) i dont know.
[Xperia Z1 Compact General] mickliq:
My alarm app (Alarm Clock+), same app I've used with an SGS4 and Moto X (each running basically stock 4.4.2) that allows me to choose a song, won't play the music. Stock Alarm & Clock app that came with the z1c has the same issue and force closes if you try to increase volume.
