My bad, this is not a bug.. edited

what a bug i found ( i think), Everyone (except for those who doesn't) knows that sin 90 = 1 but what i found here is such annoying thing.

i recently used my calculator app ( xperia brought one ), and tried to use it, and the result was 0,89

Then I re-calculated again, and i input sin 80, what i found was -0.993888654

I'll try to reflash my x z with another ftf.

Oopss.. My bad... i think it was a bug, but it wasn't, i did choose RAD.. my bad
[Xperia Z General] emeemisri:
4.3 is the best firmware sony had made for Z.no kit kat ever for my Z until sony fix its bug
[Xperia Z General] kingvortex:
...

You have your calculator in radian mode. This is not a bug.
[Xperia Z General] Invicta:
Lolz, correct.

I have also the same prob in my Z, gpe services kill my battery and serious overheating
[Xperia Z General] mangbhoy:
Thanks for the reply!

Doesn't work for both FLAC and MP3 types - via the bluetooth headset Sony SBH50.

I can get it to work via the headphone jack, though (but kinda misses the point of me using a bluetooth headset).

I've also tried the following players:

1.) Native Walkman app

2.) WinAmp

3.) Google Play Music

4.) Poweramp
[Xperia Z General] ravdo:
Hmmmm...... not sure what caused it then. I'm using a bluetooth headset too (MDR-1RBT), and it works flawlessly with Player Pro+DSP Pack.
[Xperia Z General] mangbhoy:
Thanks, as of now, I've returned to stock 4.3 (101). Hopefully there'll be a solution to this in the near future.
[Xperia Z General] lechuckthepirate:
Hi everyone... this morning I have received a new OTA in my Xperia Z... it was a little update, about 0,2mb that installed fast.

There was no explanation about what was being fixed, and after the update, I keep having same build and rom version... so I'm totally on the blind side.

It would be great if it'd fix the Google Play Services battery drain issue, since I use foursquare and swarm all the the time, and they won't work if I disable location services...

My version before and after the update is 4.4.2, 10.5.A.0.230 ... strange?

Anyone got info on this update?
[Xperia Z General] kingvortex:
Minor updates like that that don't change the software version are normally updates to the customisation only (that is the included apps etc).
[Xperia Z General] gerickjohn:
Strange, I got the update as well, also to the Movies app, it can now play MKVs as what the changelog said.
[Xperia Z General] pchandarana28:
Ive got the same thing, also the lag on quicksetting menu goes if you force gpu rendering but seems to kill my battey
[Xperia Z General] Jersern:
Weird "Mobile networks" bug?

Firstly, I can't connect to my service provider (so no signal even when I'm out in the open) and secondly when I try to use the "Mobile Networks" option in the settings menu to adjust my network, setting force closes.

BTW: defs not a SIM card thing

ALSO: ton of apps crash when I start up my phone.
[Xperia Z General] ivodonev:
Same here. I need to recharge every few howrs. This is terible!
[Xperia Z General] nemer12:
i also recieve the update but dont know what changes...also movie app
[Xperia Z General] B14ck7hund3r:
I absolutely can't relate to what you wrote. Sure they have a bug here and there, but eighty percent of RAM used by google play? Battery drain? My RAM is about fifty percent with all apps that I use regularly and in battery usage history google apps never appeared (except with the 4.4.52 bug with network location wakelocks).

Sure, sd card limitations are annoying, but this is the only thing you mentioned that really is a problem.

Ps: is mother (60+) has a galaxy a3
[Xperia Z General] kingvortex:
Can everyone that is having Google Play services battery drain check that GPS isn't activated. Since KitKat, the option has been slightly hidden.

Settings - Location - Mode

Set it to "Battery saving". That solved all battery drain relating to Google Play services for me.
[Xperia Z General] B14ck7hund3r:
I'll try asap. Setting to GPS only solved it too but google how doesn't work properly
[Xperia Z General] lechuckthepirate:
That's not solving something, but workarounding it... I need fine location info for the app I'm testing, for foursquare and swarm, and other things... this didn't happen before. In 4.3 I had fine location activated all-day-round and the battery life was very good. With 4.4 you set fine location and Google Play Services goes mad eating battery....

Let's hope Sony or Google post a fix for this because it's very annoying.

Cheers!
[Xperia Z General] kingvortex:
Semantics. Maybe I should have said "stopped" instead of "solved". In any case, disabling GPS stops the massive battery drain for me. I posted it purely because the setting has moved and some may not realise that GPS was activated.

GPS has always been a source of battery drain on every device I've had.

If I need fine location, then I just turn it on. It's not ideal, but better than your phone running out of juice halfway through the day. :)
[Xperia Z General] lechuckthepirate:
Of course.. and I didn't men to offend you, but turning GPS off is not the solution for some users that need fine GPS location. Will help the rest of the people... I'll give you that XD

Cheers!
[Xperia Z General] kingvortex:
No offence taken. I realise that it's not an ideal or even permanent solution, but it will help some if it works. :)
[Xperia Z General] B14ck7hund3r:
Sadly this didn't work, wakelocks are back. Do you have the "always look for location when wifi is off"-option set?
[Xperia Z General] kingvortex:
In Advanced WiFi settings? No, that is disabled.

This problem with Google Play services is an odd one. It seems to affect different devices in different ways. I have very low battery drain and get up to 6 hours screen on time some days.
[Xperia Z General] gerickjohn:
So.. The update temporarily shut off my signal and refreshed the Sim Menu, some people may know what that did? Then some Software update confirmation popped up. I also tried disabling GPU Acceleration, the Notification bar is smooth now but Settings is still lags.
[Xperia Z General] Sirence:
I have the same problem.

Anyone know what is causing this?

I also have gpu rendering off.
[Xperia Z General] Ben Ling:
Guys new update .233 is coming...

Hopefully Sony will fix most of the bugs in this firmware but i didn't face any problem at all...
[Xperia Z General] Invicta:
so you didnt face lag in setting menu and other apps when scrolling etc? i find this hard to believe

you dont even have the notorious black screen when locking and unocking the device?

i am asking you because i have flashed kitkat a dozen of times and of different regions and they are all the same
[Xperia Z General] nemer12:
I have lag, if i select live wallpaper I have lag like hell, the SMS APp is very laggy or sometimes I cant enter it, and i saw that sometimes when I talk at phone I can hear the other person and he can't hear me also and I have to reboot the phone so I Can hear him...battery life etc...more things.

There were no more lag after I force gpu rendering.

Overheat and reboot issues

Hi,

I got a problem ith my xz c6603 last night,

my phone was overheating when playing a game, then automaticly reboot and work as good as usual

that was the first time my phone got auto reboot when overheat

So is that normal? or i've got serious problem with my phone?

my phone running on kitkat 4.4.2 stock firmware 0.230

Perhaps someone can advise to me,

Thanks

Mifta

:confused:
[Xperia Z General] oranglewat:
Hi guys. Dirty update my c6602 last night, with force GPU rendering on I see a slight lag compared to the previous update (Just a tiny bit). Battery life is, ehh, so far seems to be no better or worse than before. I have a live wallpaper that turns to blank every time I lock the phone then unlock it and takes a few second to load. I do not use google now though. I did not find any stutter when I play music during my morning commute (MP3 With PowerAmp and wired headphone). Camera launch time is slightly faster. Can't say I like that the quick setting is on another page in the notification area (But faster access to the wifi setting area when press and hold the wifi icon. nice). Overall for me it's ok with marginal improvements.

[Xperia Z General] chefnoob:
Updated through OTA with generic AU... Im also experiencing lag on settings but was fixed with GPU Rendering...also, had some lag on browser and facebook but what was weird is that when I updated the apps, lag seemed to improve, if not gone completely. Could it be app optimisation issues?

Also battery life is ridiculously... Good!

15 hours now, 1 hour screen time, 4G network...and still on 83%!!!

Terrible update. Hate the new pull down notification bar. Hate that I cant use XperiaLauncher2 with this new firmware.

Pictures and videos couldn't be deleted through quickpic or video player. They keep reappearing.

Had to go to file explorer to manually delete.

Will go down to service center to downgrade.

Dude MSAA is GPU intensive does the opposite of fix lag. MSAA is a type of anti aliasing that smooths jagged edges, not a magical anti lag solution.:good:

Why did u feel the need to quote some old msg.. I was mislead by some newbie dev.. And i was corrected here in this thread itself.. :silly::silly:
[Xperia Z General] oranglewat:
After a few days, noticed that the battery is better after I turn off my live wallpaper. but, it'll suck so much energy whenever I listen to songs on my PowerAmp. The mediaserver thing just sucks so much life off my batteries.

Hi,

I got the KK update from Malaysia. I update via PCC and direct from 4.3JB with all apps and data retained.

Starting, I don't face any battery drain issue, but 1st boot is quite long and hot, after couple of hours phone just normal. Except, lag in settings and opening apps/apps switching. Then I did full charge and observe it for next day.

Battery drain only 9% from 1am to 6am with gps,data,wifi off.

Problem 1( lag):rolleyes::

I do feel lag during scroll down notification/settings, apps switching, loading apps when open, and most important is keyboard typing is laggier than 4.3 (not sure as slightly lag in whatsapp but serious lag in wechat).

Problem 2(apps installing/uninstall):(:

2nd day, i install couple of apps and found out problem with apps installing where 4.3 it took only approximate 10-20 sec to install an app, now it took around 5-10minutes to install an 20mb++ app. It happen to uninstall apps as well, 3-10minutes only it could finish uninstall. I google and install SD maid , clearing something in a folder name LOST.DIR (7GB) and it reduce time installing/uninstall but still longer(2-5min) than 4.3JB (10-15sec?). Any one encounter this before or know any way to fix this bug before?

Problem 3 (minor issue:silly:?):

walkman does feel like pause 0.5sec-1sec during plug-in listening music. (I did turn on Force GPU rendering, now turn off and observe by tomorrow)

Problem 4 (battery):

Battery wise, 1st day I do have no problem, but 2nd day i got battery drain, not from google play but from MEDIA.

Charging phone 2 hours only increase (20%), and freak me out. In the end, I open all media related apps, and force close them, reboot, and phone back to normal with yesterday idle 5am-7am battery drop from 100% to 98% with wifi connect.:D

Overall:

Battery does improve in term of gaming and normal usage does not cause as much battery as 4.3JB, but it is possible the root cause of lag(in scrolling notification, apps switching and opening apps etc?) as some said battery improvement come with lower processing power needed.

Overall, still ok, but does hope for bug fix for lag, keyboard lag and others. Happy cause finally i can install and play google camera blur lenses. :p
[Xperia Z General] matjee:
I've got a little problem with my batty too. Not from Google Play, but from screen. Week ago it used 20%-25% of battery, but in last few days I noticed that it grew to 40%. I tried with 4.4 and 4.3 and it exist in both roms. I also changed the brightness but there were no effects. Any suggestion to reduce it? :(
[Xperia Z General] AntonyStark:
Its supposed to be higher higher is better.

Anyone having a problem with the OTA update? I get a generic "the update failed" message and that's about it.

I'm on a rooted, LB, 4.101 (4.3) standard image. Plenty of free space on the internal storage.

Can anyone point me to a log file location to figure this out?

Or

Will updating via PC companion retain root?
[Xperia Z General] neoxx3m:
OTA update won't work on rooted phones.
[Xperia Z General] colacin:
I wasn't aware of that.

I also didn't realize it was in a different thread that people had said they were rooted and did the OTA update and retained root. I'll take this topic over there.
[Xperia Z General] kingvortex:
OTA update does work on rooted phones. I updated 4.3 to 4.4.2 via OTA and kept root.

OTA updates don't work if your bootloader is unlocked, however.

Hey guys,

Tried this out and, so far, it works for my Mediaserver problem (Battery drain)

So guys, i found this article.. So 4.4.2 was an initial phase of KK.. 4.4.3 will come for Xperia Z, and according to what i saw, Z2 had more buggy 402 fw than XZ's 230.. And these bugs will be fixed in 4.4.3.. So have a little faith.. ;)
[Xperia Z General] OsiBasi:
Gotta say Kitkat sucks... I remember google saying it would run smoothly on even 512mb devices... But I think they meant they will make any device feel like a 512mb device.

Did a fresh install (Full wipe)

Installed .230 through Sony update service and towelrooted it. System is completely smooth, no modifications done, some lags at settings first few times but it fixed itself.

But gaming experience? Awfull, Tried playing some Super mario world on SNES emulator, same emulator i've used on my xperia play 3 years orso ago w/o any problems. Lagging like hell, same with Streetfighter IV both unplayable. Also Tv/hdmi seems more delayed than ever.

Downgrading now.
[Xperia Z General] neoxx3m:
My gaming experience is fantastic on KK, smooth and fast like on 4.3. And MHL work's fine, I'm playing Real Racing 3 on my TV a lot, and theres no delay.
[Xperia Z General] fernando823:
Any update on the battery drain?? I just cant stay like this, I have to charge my phone 2/3 times per day... and I have several friends in the same situation.

I tried everything to stay in 4.4.2, even full wipe but nothing.

Also tried to flash with the previous stock firmware but my phone didnt switch on, it entered in a reset loop so, had to flash again to 4.42.

Any help to downgrade to 4.3??

Please help!!! Thanks
[Xperia Z General] Rajeev:
Flash . 101 ftf (4.3) with a clean wipe via flashtool. Try to update ur flashtool to latest one.. Make sure ur phone has atleast 40+ % battery backup
[Xperia Z General] SalamiQueen:
So general consensus is to stay on 4.3 & avoid updating to KK for now until a new update with bug fixes?

I'm intrigued whether mine will have any problems, but it seems everyone's different!? :eek:
[Xperia Z General] Rajeev:
I am always happy with Kitkat.

Hi,

I recently got my brother's Xperia Z after he got the Z2 for himself, well, I keep getting a notification about an update 10.5.A.0.230, the phone is currently running Jelly Bean 4.3 firmware 10.4.1.B.0.101.

My question is this....

I have tried to read through this thread, it's way too long to keep track completely, I've seen comments that contradict each other, seems there are bugs in the Xperia Z kitkat but they do not affect every device the same, am I correct?

So, what would you recommend to do, update or not?

Thanks.
[Xperia Z General] fernando823:
Mi advise is clear: DO NOT UPDATE until the next firmware from Sony, where hopefully they will fix the battery drain issue
[Xperia Z General] SXZdabbler:
My phone runs fine on 4.4. When the battery drain goes up I reboot the phone ? and battery usage then returns to normal. I've had to do it twice since updating .
[Xperia Z General] vollachr:
OK, well Anyone else have any input?

Also, correct me if I'm wrong but isn't there a workaround to the battery drain issue?
[Xperia Z General] SalamiQueen:
My thoughts exactly! I'm in the same boat as you and have nearly updated several times but held back thinking about all the bugs some are getting. Guess we'll never know for certain until we try ourselves personally! But for now I won't update until/if a bug free update appears. My 4.3 works smoothly and perfectly, so am not desperate to change to something that could potentially ruin the phone =P

As for the batt drain, I got it on jellybean so it's not just kitkat. Just fixed it by disabling gps once and clearing data, worked since then so I'm sure it's same workaround for kk
[Xperia Z General] mbadger:
My story.

I updated to 4.4.2 and my battery life dropped to less than 8hrs!

I then uninstalled the Google play services update (sony work around) and and got force closes all over the phone. The bigest problem was the phone temperature, it would get so hot that you couldn't hold it your ear.

I got desperate to have my phone back. I unlocked the boot loader. Rooted the phone and rolled back to 4.3.

I tried two different custom roms, and settled back on the official sony 4.3 release.

My battery now lasts for 9 hours and still gets hot under intensive use.

I had to have a reliable phone so I went and bought a new phone (s5).... thanks v much sony for f**kn up my phone.

OK, well, I guess I'll just create a backup using the TWRP/CWM recovery environment and try to update to see how it works, this way I can easily go back if I want/need to.

Update this week to 4.4.2.

Did notice the lag in settings and notification bar, but after enable GPU Rendering all the lag went away. And now it's as smooth as 4.3.

Also not having any problems with battery, it may even be better then on 4.3. Not seeing overusage of Google Play Services.

I'm on KPN NL .230.
[Xperia Z General] pidigi:
Do not update

Battery drain issue is too bad .Do not update this version .
[Xperia Z General] fernando823:
SERIOUSLY, DO NOT UPDATE YET: http://www.inferse.com/15383/sony-warns-xperia-z-users-avoid-android-4-4-2-kitkat/

On top of that, there is nothing special in 4.4

---------- Post added at 02:33 PM ---------- Previous post was at 02:24 PM ----------

By the way, this aplication claims to fix the drain. I couldnt test it yet

https://play.google.com/store/apps/details?id=com.playfulgeeks.gservicefix
[Xperia Z General] kingvortex:
First, that article is misleading. Sony has not warned users not to update.

Secondly, that app apparently does nothing except mess with the default homescreen setting, then tell you to disable location services, which is already a workaround without installing that app.
[Xperia Z General] fernando823:
Check the comments for "Google Play Services" in "Google Play" filtering for users of a Xperia z c6603, and you will realize that the problem with the battery is huge... and basically all the users are reporting the same problems, 60-80% of battery consumption and several claim that they got the phone from SAT back in 4.3 again.

https://play.google.com/store/apps/details?id=com.google.android.gms
[Xperia Z General] vollachr:
I haven't used the xperia z phone for long, just got it from my brother about a week ago and still haven't gotten around to get a micro sim card for it so I couldn't use it much but from the little I did use it on 4.3 and my experience from updating to 4.4.2 today, I don't see any special problem with kitkat, battery life, if I am to believe to the app I have that tells me how much time the battery have left is longer that it was on 4.3 and the only lag I found was with the notification pull down and even that was inconsistent.

Yeah, decided to go ahead and try for myself, figured it would be the best and worse case scenario, I created a backup so I could go back to 4.3 but as I said, so far don't see any real problem that needs to worry me, but I haven't had a chance to use it much, will see in the next few days maybe.

Beside, from what I read, the battery issue have a workaround, more than one method to my understanding and I'm not such an heavy user.
[Xperia Z General] kingvortex:
I already know what's causing it. I didn't say anything about that.

I said the article you posted is lying about Sony advising users not to upgrade to KitKat.

From that article -

Sony NEVER said any of that anywhere. The author of the article either failed at reading the source he cites or is just making things up to get page views. Either way, the article is a load of click bait rubbish.

I also said the app you posted to "fix it" is fake. Read the reviews of it. It does nothing, then advises you to turn off location services. That is already the workaround for the issues with gms. No app required.

Reading before replying helps. Please do so before replying to me again. Thanks.

So far no lag or battery drain on my SG rom but I do have a very annoying problem on my XZ. after I make a call or incoming call. when i pick up and place it beside my ear, by right it would turn off the screen and after the call hang up the screen should come back on but instead it does not and I have to press the power button twice to bring the screen on again.
