[Sony Xperia P, U, Sola, Go] WayOfLife!:
JB wont happen anytime soon (if not imo, it wont come at all)

Look how long it took sony to roll out ICS and to my knowledge, i tink some countries still do not have ICS available yet
[Sony Xperia P, U, Sola, Go] Vaste92:
Zte just released officially jb 4.2 for a smartphone that has single core 1 GHz and 512 mb RAM :) so, 4.2 on 512 mb of ram is definitely possible!

Also, cm10.1 has been ported on galaxy S and galaxy W.
[Sony Xperia P, U, Sola, Go] doctor_droid:
Sony will say try our new line up as

Old one is capable bt we need ur hardearned money and want to make the fool out of u

When devices r running 4.2 we have no info even of update of 4.1
[Sony Xperia P, U, Sola, Go] ilgreco112:
I don't see the point of getting JB, Sony OEM is so much better on ICS than JB 4.1, maybe stock 4.2 is a bit better than sony ICS but not much, I actually have Xperia P and my friend that has Gnexus showed me the differences, not much, actuallly he just got a Timer on 4.2, swipe keyboard, and all stuff that sony already has on 4.0 =)
[Sony Xperia P, U, Sola, Go] Felimenta97:
Photosphere, new side load installer, expandable notifications. Other new under the hood features. Want more?

"What really matters in this world, anyway?"
[Sony Xperia P, U, Sola, Go] mzr7:
Lol why do you even bother with people on this thread I've given up.. It's no use.
[Sony Xperia P, U, Sola, Go] MadManMark:
Surely the most coveted feature of JB is project butter
[Sony Xperia P, U, Sola, Go] KeLsTaR:
JB for Xperia Go will be< and it`s exactly. So I think for sola and U it will be too
[Sony Xperia P, U, Sola, Go] techno-np:
Surely the I want 4.1 for the Project Butter.. It is the only thing I want. And if I don't get the buttery smoothness in stock Rom then CM 10 all the way!!
[Sony Xperia P, U, Sola, Go] zed011:
Yes the most sought out thing for me is smoothness too. I don't want to see any more stuttering on the home screen.
[Sony Xperia P, U, Sola, Go] ilgreco112:
my friend having a galxy nexus told me you dont see any difference btween ICS and jelly bean, project butter doesnt really help as you can't see the difference, so I can wait the time they want to get JB
[Sony Xperia P, U, Sola, Go] theronkinator:
Project Butter makes a big difference, I've compared ICS and JB on the same device.
[Sony Xperia P, U, Sola, Go] hanifh:
then he sure doesnt know what he is talking about :cyclops:
[Sony Xperia P, U, Sola, Go] zed011:
That is because the nexus is already very smooth already on ICS. On a device whose cpu isn't a powerful it will help more using gpu
[Sony Xperia P, U, Sola, Go] ilgreco112:
he surely knows what he is talking about and my xperia P is also very smooth on ICS, so I'm sure I won't see any difference
[Sony Xperia P, U, Sola, Go] MadManMark:
That just means your brain isn't picking up the framerate lag, I was like you till I played around on an iPhone for a while, realised my Xperia P was sometimes sluggish flicking through menus or homescreens
[Sony Xperia P, U, Sola, Go] krob8768:
Is there a CM10 for Xperia Sola?
[Sony Xperia P, U, Sola, Go] rohit3221:
Nope...
[Sony Xperia P, U, Sola, Go] techno-np:
CM 10 will b released when official JB will come..
[Sony Xperia P, U, Sola, Go] thunderising:
ABSOLUTELY. That is the MAIN reason, alongwith and better RAM management, and GOOGLE NOW that I want Android 4.1 Jelly Bean.

Android 4.2 just adds some apps. I can live without them. Or we can simply flash those apps into our Jelly Bean ROM (once we get Jelly Bean).

Sony could pull a surprise and simply update our phones directly to Android 4.2 Jelly Bean.

But I'm afraid that will most definitely be the LAST update our phones will see. Even then, I'm cool with it. Hope Android 5.0 Key Lime Pie (whenever it launches), gets ported to our device.
[Sony Xperia P, U, Sola, Go] josie87:
So you guys need JB for scrolling, right? ;)
[Sony Xperia P, U, Sola, Go] techno-np:
Yup I always scroll around and play with my device for no reason...
[Sony Xperia P, U, Sola, Go] MadManMark:
Those were just examples, no need to be an ass about it
[Sony Xperia P, U, Sola, Go] spawk:
we have also slim rom for porter if need test to port

"What really matters in this world, anyway?"
[Sony Xperia P, U, Sola, Go] icedef:
I want to have JB on my Sola as well, it's my first android and ICS is just killing the hell out of my ram. :(
[Sony Xperia P, U, Sola, Go] slackerzz:
Good news, from the SonyMobile Italian facebook page they wrote that xperia sola will get JB,

so we dont know when, but it will happen

Hello All,

Great News... Samsung I8190 Galaxy S III mini Is Coming Out of the box with the Android OS, v4.1 (Jelly Bean)

and guess what its uses Chipset	: NovaThor U8420

whereas the Sony Phones Xperia P Sola and Go uses Chipset : NovaThor U8500

so i guess it will be easy to port the OS form Mini to the Xperia's

Dav's Reply :D
[Sony Xperia P, U, Sola, Go] josie87:
Would be awesome if it would be that way, sadly it's not. :(
[Sony Xperia P, U, Sola, Go] elia222:
Sony mobile Italy announced official jelly bean for u and sola: www.androidworld.it/2012/11/29/sony-mobile-italia-conferma-jelly-bean-per-xperia-u-e-sole-121997/

Sorry for the Italian article but I don't have one in English ;)
[Sony Xperia P, U, Sola, Go] Irseq:
Then it's coming to P too.
[Sony Xperia P, U, Sola, Go] jimilegolas:
Was that already announced?

Sent from my Xperia P
[Sony Xperia P, U, Sola, Go] Irseq:
If it's coming to U and Sola then try to think a bit.
[Sony Xperia P, U, Sola, Go] thunderising:
Now that is some awesome news. Does it give a time frame for the update?
[Sony Xperia P, U, Sola, Go] elia222:
No.. In brief Sony just said that there is a plan for the jb update and that for sure the xu will be updated.
[Sony Xperia P, U, Sola, Go] Vaste92:
This is all the discussion:

Users:"Hi, Sony mobile IT has the jelly bean upgrade plan for Xperia U been prepared? Will it ever been released for that phone?"

Answer: "Sony is still preparing the update plan for jelly bean upgrade for Xperia U. So, the answer to the second question is: yes, Xperia U will be upgraded to Jelly Bean."

Hope this will help :)
[Sony Xperia P, U, Sola, Go] jimilegolas:
Are you freaking kidding me?

Of course we are going to get JB. Did you have any doubts about that?
[Sony Xperia P, U, Sola, Go] spawk:
hey jb 4.2 is out if any one want test to compile http://developer.android.com/about/versions/jelly-bean.html
[Sony Xperia P, U, Sola, Go] spawk:
if any one want test to build i have ziped dump from last sdk but apps are odex need deodex and make or replace and work if any one interest just pm i upload it :D
[Sony Xperia P, U, Sola, Go] mirco_pa:
Sony Mobile IT confirmed that XU and Sola will be updated to Jelly Bean. No ETA for now though.
[Sony Xperia P, U, Sola, Go] dragxdk:
Where have u read this?

with tapatalk
[Sony Xperia P, U, Sola, Go] elia222:
Just read the page before this one :silly:
[Sony Xperia P, U, Sola, Go] icedef:
I really hope we'll get JB on Sola, they have the same specs as XU it would be unfair for us XSola users if only XU gets JB.
[Sony Xperia P, U, Sola, Go] DeepMemory:
Well the Samsung Galaxy S Advance is getting JB in January and it is using the same chip as XU and Sola, so I am pretty sure we are getting JB just hope they have ETA asap :fingers-crossed:
[Sony Xperia P, U, Sola, Go] :
Yeah I totally agree with you all. :fingerscrossed:
[Sony Xperia P, U, Sola, Go] jimilegolas:
There's been quite some time since K900 last posted here.

No more inside info to give regarding this much awaited update?
[Sony Xperia P, U, Sola, Go] Felimenta97:
He moved away from here. Too much hypocrisy here, according to him (agree at certain point)
[Sony Xperia P, U, Sola, Go] techno-np:
What about this news? seems too good to be true..

http://www.androidauthority.com/sony-xperia-u-jelly-bean-update-december-135675/
[Sony Xperia P, U, Sola, Go] zed011:
Before Christmas would be nice but don't count on it
[Sony Xperia P, U, Sola, Go] sikolymester:
ROFL. They did not even finish to roll out ICS to SOLA. Guess what, if they can't deliver an update to all phones in 2 months, how would they be able to port JB in 2 months?

To update would only take them a couple of code lines like this:

If (strcnmp(version, "1261-9705") == 0 )

{

updateICS();​

}

But no, they can't find the guy to add the 1261-9705 number to the roll out list.

I read they have fired a lot of people at Sony, maybe they only kept those working for the marketing department.
[Sony Xperia P, U, Sola, Go] techno-np:
Now Sony needs a make over..its the same looking UI since android 2.1 .

It needs to have more functionality and features lik the sammys TW UI.
[Sony Xperia P, U, Sola, Go] josie87:
To be honest, I absolutely dislike TW. Sony is pretty close to stock, that's why I like it.
[Sony Xperia P, U, Sola, Go] KeiranFTW:
Touchwiz not only sounds like a UI invented by someone with morals close to Jimmy Saville, but also looks horrible, as if it was designed for kids, with blue and green everywhere.
[Sony Xperia P, U, Sola, Go] techno-np:
Guys The galaxy S 3 mini is released with android 4.1 JB...it has same Nova Thor chipset lik us....so is there any way of getting it on to our devices... Any dev's here?
[Sony Xperia P, U, Sola, Go] zakk87:
S3 mini has nova thor 8420, we 8500. The same chipset doesn't mean that will be good for other hardware. (why developers don't port our SW to galaxy ace 2? )

any update on jb for xperia go?
[Sony Xperia P, U, Sola, Go] techno-np:
We would have gotten JB by now if we had snapdragon cpu.... Unlike ST Ericsson they released all the things to the devs..
[Sony Xperia P, U, Sola, Go] Adityagrao:
The JB Updates Dates will be released by Sony In this month end
[Sony Xperia P, U, Sola, Go] thunderising:
What if Sony says

"Jelly bean for U, Sola, Go will be made available..... (wait for it)..... Q3 2013."
[Sony Xperia P, U, Sola, Go] josie87:
Very unlikely. My guess would be december or january. But who really cares? CM9 is advancing pretty fast. CM10 will follow when it's stable.
[Sony Xperia P, U, Sola, Go] :
I guess that Sony is trying to hide the fact that we are getting jelly bean. Sony Italy let it out and Sony UK is trying to cover the truth. Maybe they want to surprise us. Sony might even be reading this forum now... Who knows?... Let us keep our hopes high.
[Sony Xperia P, U, Sola, Go] sikolymester:
One thing is pretty clear.

There will be no Jelly Bean for Sola, until Sony hasn't finished the roll out of ICS.

FYI: Sony still hasn't.
[Sony Xperia P, U, Sola, Go] Damiano1234:
Bull****!! Sola gets jb and don't say no
[Sony Xperia P, U, Sola, Go] Howlin' Wolf:
I don't think we'll see jb this year. Mayve sart of February or something like that, we'll see...

[Sony Xperia P, U, Sola, Go] fakhrulfaris:
The 2011 Xperia smartphone lineup is not getting Android 4.1 Jelly Bean

In a phonearena blog said "Sony has looked into the update and for various reasons has decided that Ice Cream Sandwich is the most those devices can handle"

I cant give you the url beacause i am newbie here. Try search google for "jelly bean for xperia" and look at phonearena links :)
[Sony Xperia P, U, Sola, Go] horizophon:
Really looking forward to JB!
[Sony Xperia P, U, Sola, Go] Lvw2000:
Sony just announced the "Xperia E" which will launch early next year with Jelly Bean out of the box.

http://www.phonearena.com/news/Sony-announces-Xperia-E---affordable-Android-with-HD-Voice_id37328

So I really don't think we have to expect Jelly Bean this year... and it looks like CM10 will also take a while because they need some drivers and stuff for the NovaThor, and those probably will only be released when the official Sony JB update is out...
[Sony Xperia P, U, Sola, Go] vikirules26:
jellybean xperia u confirmed

I had last night asked a question to twitter team to confirm rumours and finnally KP announced it i have a screenshot u can visit xperia team twitter page

This has been said many times but people keep posting rumours, just be patient we won't know anything new till the announcement
[Sony Xperia P, U, Sola, Go] Adityagrao:
Well we diacussing about it won't have much effect Sony will release when it wants to.

I am using xperia P not nexus
[Sony Xperia P, U, Sola, Go] MarcoLoves360:
i want it so hard
[Sony Xperia P, U, Sola, Go] Rapier07:
And that is why you should get a Nexus, no matter how ugly it is!
[Sony Xperia P, U, Sola, Go] noim:
Waiting for the Xperia nexus...

I don't want to jump to any other manufacturer...i love Sony and their design....
[Sony Xperia P, U, Sola, Go] reptile64:
And we, Xperia owners, will always be one step behind..! So sad.. :crying:
[Sony Xperia P, U, Sola, Go] Elsydeon:
It'll probably take quite a while but I think at least the Xperia S will be guaranteed a Jellybean update...wasn't it recently selected by Google to become a part of AOSP, essentially turning it into a Nexus device? Sony did already hand Google the necessary proprietary info, so I think it's just a matter of time. I actually bought an Xperia S after seeing that news, it made me feel a bit more confident about its future.

Make no mistake about it though, I'm currently on a Galaxy Nexus on Jellybean and comparing it with the Xperia S on ICS, the Xperia S' interface is a LOT more laggy and slow. If the Xperia S never does get Jellybean, I'd probably not keep it.
[Sony Xperia P, U, Sola, Go] K900:
Google never made the Xperia S a Nexus class device. All future updates will still come from Sony, everything Google did up until now was an experiment just to see how hard will it be to add a new device to AOSP.
[Sony Xperia P, U, Sola, Go] tel033:
Still it's a good sign for Sony.. It maybe taking a while but not Samsung nor htc updated the whole portafolio and of course they're flagships are good supported but at least herr in ñu country most gs2 never received official update and my sisters galaxy nexus update to JB last week! Me? I've never had updating issues
[Sony Xperia P, U, Sola, Go] XperiaU:
Lol you guys are talking about JB...

We don't even received ICS yet.
[Sony Xperia P, U, Sola, Go] Elwino2.3:
It's ok! ICS will come lol!
[Sony Xperia P, U, Sola, Go] tarbyonline:
TBH I'm not that bothered about getting JB on my xperia U ATM, I would be quite happy with a stable build of ICS. What bugs me is that we have had ICS on the xperia mini pro since about June yet the Xperia U launched in May with Gingerbread despite the souce for ICS being available from the end of 2011. Surely it would have made more commercial sense to release the newer phones with ICS first then update the older range instead of having the older range running more up to date software. Also the drivers etc have had to be developed for both gb and ics instead of just ICS if the phones launched it android 4.
[Sony Xperia P, U, Sola, Go] crack73:
I just want a stable OS. GB is laggy all around on my XU and seems slower on some thing than my old Live With Walkman. That's kinda disappointing, really. I just hope ICS solves the performance issues, I know this chipset can do great things.
[Sony Xperia P, U, Sola, Go] XperianPro:
I had to Live before I bought U and I agree with you 100%
[Sony Xperia P, U, Sola, Go] josie87:
I don't see the problem. At least on my P, ICS is pretty stable, fast and consumes less battery than GB. JB is announced, so I am happy. But seriously: the current ics is nearly perfect. Good things take just their time. And I hope that they will take their time to deliver us a rockstable JB.
[Sony Xperia P, U, Sola, Go] XperiaU:
I hope Xperia U will get both updates....
[Sony Xperia P, U, Sola, Go] realfelix:
It will.
[Sony Xperia P, U, Sola, Go] noim:
Any word when JB will hit our device Xperia P? I the current iCS is very fast and stable.i think it is more faster than GB.
[Sony Xperia P, U, Sola, Go] lilude56214:
No, they always said that we would bring out JB as soon as possible.
[Sony Xperia P, U, Sola, Go] sxpu_nishant:
Talk about ICS first.!!jelly bean is way far!
[Sony Xperia P, U, Sola, Go] justkiddinghere:

We want JB. The ICS is very slow in the Xperia alone. : (
[Sony Xperia P, U, Sola, Go] neoxx3m:
What do u think, JB will be epic fast? 6 times faster than ICS? Don't live in delusion man.
[Sony Xperia P, U, Sola, Go] mzr7:
Exactly!!! Jelly bean will only remove lag!! It won't make your phone process faster like load angry birds faster! It'll make animations smooth and lag free. That's about it.

I'm talking project butter.
[Sony Xperia P, U, Sola, Go] techno-np:
Well ICS is Pretty fast enough for me...I am satisfied...I can wait patiently till Sony releases bug free JB ...just hoping its 4.2 bcuz I doubt Sony is going to give us any further updates. ..fingers crossed
[Sony Xperia P, U, Sola, Go] zakk87:
4.2 is full of bugs, maybe 4.1.2 or 4.2.1.
[Sony Xperia P, U, Sola, Go] DevSwift1:
For ALL!

We need device source from St-Ericsson. Without That, development is practically impossible... We have to write a petition for access to sources
[Sony Xperia P, U, Sola, Go] techno-np:
Yes we have to do that... with out those s sources no further development can be made even after Sony leaves support.... with the P,U,Sola& Go we have a very big community I think so...
[Sony Xperia P, U, Sola, Go] Harish Bhukya:
low end devices like xperia tipo got cm10:mad: and we didn't...:(:(feeling sad about by Xperia p running still on ICS...While my another device samsung galaxy mini running jellybean(android 4.1.2):confused::(
[Sony Xperia P, U, Sola, Go] neoxx3m:
CM10 on tipo is laggy and it's not for daily use. Why u need laggy OS on ur XP?
[Sony Xperia P, U, Sola, Go] techno-np:
It's laggy because they don't have the processing power to run CM10...
[Sony Xperia P, U, Sola, Go] neoxx3m:
It will be laggy on our xp in the beginning of developement too. Till stable version Sony will release official JB update.

The only interesting thing about JB is project butter, I don't even know if it will really make a difference, I hope it will
[Sony Xperia P, U, Sola, Go] jtdc:
correct! majority of 2011 Xperia even have better specs than Xperia E!

in any case, once Xperia E comes out, high chance its ROM can be dumped and modded to be used by other models.
[Sony Xperia P, U, Sola, Go] Vilo76:
It is not that simple.

I've tried JB on my previous phone, a Galaxy Gio (800Mhz single-core + 256MB), and it was really smooth (better than stock GB).

JB (and all other Android revisions) is a system that is not dedicated to a particular hardware.

Thus, performances are sacrificed for compatibility.

But, once adapted to a particular phone/hardware plateform, results can be really astonishing.
[Sony Xperia P, U, Sola, Go] Vaste92:
Sony Xperia E will have kernel 3.4! Maybe all the JB update will be based on this kernel? :)
