I assume this means the TX will not see JB until April, so much for end of March. Time to sell the TX for the ZL

I've read everything completely what was mentioned in the Sony forums, nothing was mentioned about TX in that thread. So Xperia blog is just guessing whats going to happen.

The Sony moderator was mentioning about the "Xperia T" walkman bug fix and there wasn't any discussing about TX in that thread. Link me to the that thread if you have found anything regarding TX.
**** sucks. Jelly Bean's been announced almost a year ago and only now Sony is rolling update -- delayed from the original announced date, even. For god's sake, the Xperia S came out last year with Gingerbread! I just love their phones, but their updating policy really makes you question certain things.
Updating policy is just an issue with every brand I've looked at. I just consider updating through custom roms most of the time.
And Google's policy about Android 18 month version support does not help any more.
By the way, this update is a good news for people (like me) who are listening some music on their phone, now we'll have to see if it solves the problem globally or not. I had the issue with all the music players I've tested on the phone. The only solution i've found was to activate WakeLock (the app) in "Partial Wakelock".

There is nothing quite like having decent hardware run on the latest version of software, where the latter would be useful in squeezing out every possible ounce of performance from the former. Well, having said that, we bring you word that there is new firmware (9.1.A.1.138) which has been certified for the Sony Xperia T (also known as the LT30p) and the Xperia TX (aka LT29i). Sony Mobile claims that this update for both devices is set to arrive from April onwards, although I am quite sure that the pegged April 1st date is not an attempt to pull a fast one on consumers.
This new firmware will also see the introduction of Android 4.1.2 Jelly Bean to the Sony Xperia TX, as owners of this particular smartphone model were said to have been waiting for far too long for some Jelly Bean goodness. Apart from that, it is said that the update will bring along with it a fix for the problem that users have suffered from when running the Walkman app on Jelly Bean firmware. All’s well that ends well, no?
I don't agree. With Android 5 just three months away, we still have no date and no news about JB 4.2...

Google hasn't even released details of Android 5.0, how do you expect the manufacturers to comment on something that hasn't completed development.
There's going to be so much hate from the other TX users, especially some "I TOLD YOU SO!" replies.
Sigh***...I just hope this will fix the OTHER Walkman bug, where music stops playing completely while browsing on the internet

ah! I've had that issue happen to me on ICS! (not tested as such in JB..)
While browsing, the music player quits and it seems like a reset since it looses which track it was playing. Posted this on the Sony forum...typical reply..try reset/repair and it behaved same afterwards. no other reply.. (they seem not to be able to replicate the issue..which happens most of the time anywayz)
i really regret buying the tx though i like it too much.the update is very frustrating.i should have opted for the xperia z instead.:fingers-crossed:

We would never officially get 5.0. Period. And 4.2.2 IS a big update as there are many things that aren't available in 4.1 and considering Sony, they need to fix the Walkman bug and sound quality and sound level. 5.0 is too far away. There won't be a 5.0 device around until the end of the year (I presume).

I read about a fix for this if your 'phone is rooted, using an app like root app delete, remove/disable smart connect and apparently the pause bug is removed in walkman.

Actually, they should still be the same problems that my TX is having. Maybe I'll give that a shot, load some songs, and run it. If it still doesn't work, I'll just continue using my Walkman Z :good:
Well after I thoughts about the awesomeness of the Sony company I something to say:
Jelly Bean was released almost TWO MONTHS AGO. For two months we, The Users, have to deal with many issues connected with crappy (yes, it's crappy) Jelly Bean released for T. Many problems experienced by many users are piling up on Q&A. This is pathetic. Walkman bug is not even fixed for now and will be fixed on week 14. Two months of waiting for the bug to be fixed. Xperia Z got its "Sudden Death" problem fixed in a couple of days and besides it already got a couple of updates since the release. Our phones - Xperia T, TX, TL and V are not even 6 months old and it looks like Sony downed the support to a minimum. I feel like I was kicked in the butt by them and their support is like "Look, people... we will release a couple of fixes but then just shut the hell up and buy our new phones! Yay!"
Take a look at Samsung. They claimed that many of their phones will receive 4.2 and then the support for better Android versions will stop. SGSII - two-years-old phone will be updated to 4.2.2! This is something amazing.
Eh. I've never thought Sony would piss me off so much. I thought it will never happen. But I see that the more Xperias come, the less they're supported. We don't even know if our T's and V's will be ever updated to 4.2. I guess Sony will just say "These phones don't have enough RAM" just like they said about 2011 phones and theirs 4.1. Hey, Sony! Xperia J has also 512 RAM and it's enough for the Jelly Bean to be released but for another 512MB's is not?! (Remember that all of 2011's have even more powerful CPUs than the J's)
Pa-the-tic.
Anyways I'm still happy of my T but the support is really screwed up...

Agree with you entirely! This why I kept saying Official KeyLimePie is a dream. They just keep releasing new devices until they overwhelm the market and the current owners feel like their devices are old. Flagship or not, this is what happens. Some people got really pissed off with me too in the other thread
Samsung doesn't support developers like Sony does, but at least they are generous enough to upgrade the firmware.
Damn im so sad now hopefully sony can change its ways! One of us xda people have to get hired as like lead software dudes and change them lol

mhh okay we have the walkman bug (I don't but others have), I can't find many other issues (nothing), I had a s3 and they released many updates for jb in a row but not because they are more userfriendly, it was because each new version had to fix some new bugs and they were much more annoying.
also jb on the s3 is more laggy than on xperia t, believe me. you can always say "why do contacts not instantly open on my t" but with an s3 you can be happy when they are open under 5 seconds and this on a Quadcore phone ...
who knows if we get 4.2 officially, even if not the port will be faster and more bug free than the official 4.2 from Samsung, I'm sure. but you are right, we have to get official 4.2 because we have bought an expensive flagship device.

Unless you got the Korean variant, you must be having the 1GB Ram variant of the GS3. JB is laggy on GS3 because of TouchWiz. Use a custom ROM and its all good. Touchwiz is such a Ram hogger.
And we definitely would get 4.2! Otherwise it's just ridiculous.. I'll burn Sony down! Its the next increment im afraid of. Also remember GS3 has many more inbuilt features than our T (software wise) such as multiwindow, so it tends to be slower. I'm not saying its better though. We got smallapps
Does anybody know which major firmware update we will be receiving next and when?
Sony seems to be awfully quiet lately regarding their update schedule.
With 4.4 on the horizon it's unfortunate the Z1 shipped with 4.2 instead of 4.3 but it wouldn't be so bad if Sony at least gave us a rough estimate.

They will probably update it to 4.3, and after it to 4.4
Sent from my C6903 using xda app-developers app
I remember reading somewhere that they are saying 4.3 would roll out in October. But I am not sure where and how accurate is this
Knowing Sony smartphones for years, i'd say there will be a really late 4,3 update as promished, and after that the phone will not get any more updates...
Also look at my answer later in this topic
Hi ssj_jaypee,
Your thread has been moved from Xperia Z1 General to Xperia Z1 Q&A, Help & Troubleshooting. Please post in the correct sub-forum in future.

there is a major update on the way as reported on xperiablog - the last 4 digits are changing which usually indicates something more than a bug fix but not likely 4.3

I'm not to sure about this update... This 1 rumour came up and nothing has been seen about it ever since.. I personally would take it with a pinch of salt for now!
The question is IF there will be a major update from Sony for the Z1 after 4.3...
And the answer is "most definitely not!"
Don´t get me wrong, i love all my sony phones, but the updates is allways missing.
Sony has released new phones many times before with an older android installed at shipping date, and then made the promished "major update" after that, to the newest current version a month or two later... This way Sony is fulfilling Goggles demands about at least two major versions, without actually giving the customer anything new at all...
Nothing new in that, just look at Sony history...
IF Sony on the other hand SHOULD decide to release 4.4 down the road, it will definitely be without keyfeatures like sony camera features and so on...
Look at the history...
Just go back and read it, start eg. with the Xperia X10...
WHEN you buy a Sony phone, you have to understand that the promished firmware is ALL you will ever get, and that Sony WILL abandon all updates faster than you can count to 10...
(So only small bug-fixing can be expected after 4.3 for the Z1)
At first it looks like Sony is working hard to put out a working current Andriod version for the phone, but they are not... absolutly not !
Just sit for 2 sec. and think about this:
WHY would Sony at all ship a brand new phone, with an older Android version installed at shipping date ?
Would Sony not have to do just as mutch work to put out the older 4.2.2, as they have to if they decided to put out 4.3 from the shipping date ?
The ONLY difference is that IF they shipped with 4.3 then they had to update to 4.4 also to fullfill Googles demands, but with 4.2.2 as shipping firmware, and a fast update to 4.3, they don´t...
This Sony-scam is ONLY to fullfil Googles demands, nothing else...

I'm not to bothered about this to be honest, maybe they can change but we have a Snapdragon 800 and Qualcomm actually release their sources (cough Samsung cough) so Cyanogenmod performance will be like awesomeness, I have my concerns regarding the camera's future with Sony being to stuck up to release the sources.

Ok then, i did read the question as if it was a question for official firmware, not custum roms...
- and my answer was becource of that, minded on the official SONY firmwares...
Custom firmwares is a whole other matter, and mutch harder to guess anything about yet...
- THAT only depend on how many people who buy this phone, and who of the devs here at XDA will work with it...
You need attention from a fantastic dev to get unofficial firmware flying...
BTW:
the history shows that Sony have NOT been fantastic releasing sorces before, so don´t count on it, but keep your fingers crossed...

The phone say to you when it is a big update, and you need PCcompanion (or in the old days SEUS).
I saw from PTCRB website that a new update is coming and that is is 769. Is it true? Does sony acknowledge the issues regarding 757? Its so frustrating that i bought a new phone 1 week ago and started to posting about bugs in this group. Bravo sony -

we might not get that update just because its certitfied does not mean we will get it but i hope we do ,its over a month now and no update of yet,
Hello everybody,
i was in a local consumer electronic center (Saturn) last weekend. A sony promoter told me, that sony gives a guaranty of four years for Android updates @ XZ3. Could be true, because of the relative pure android on the device, but i want to be sure. I googled around but i wasnt able to find a official announcement about this.
Is this true?
If so, is this for main android updates (android 10, 11, ...) for four years or lets say only two years for main updates and two more years for bugfixes and security updates?
Thanks
Sony gives on average two Android versions worth of updates, which would equate to two years of support.
What @mufunyo said is about correct. Basically whatever the phone's OS was at release + 2 more versions is Sony's usual update method. So if you get the XZ3, and following Sony's usual support, the XZ3 should get up to the R version.
Honestly though Sony is also pretty good with their Xperia open source initiative and after 2 years you can still experience a rich custom ROM ecosystem for flagships. I once managed to update my ancient Xperia S (LT26i) to Android Marshmallow with a LineageOS ROM. That phone originally shipped with Gingerbread! That's 5 major versions later! (We don't count Honeycomb since it was for tablets only.)
Thats good to read, thanks for this informations. This let me tend to buy a XZ3 a bit more, but....
... at the moment, Sony has no more ANT+-support out of the box (i thin Z5 Premium was the last phone with ANT+), so this is the only reason why i didnt buy one till now. I think snapdragon 845 is ANT+-capable, but i dont have a confirmation about this and i dont have a statement from anybody about the possibility to patch the XZ3 with ANT+-features.
I need and will buy a new phone in the next ~4 weeks, and if there is no answer (or better: solution) for this, i think i have to buy Samsung again. Sad to say...
