Re: {SneakPeek} official JellyBean for Xperia S (LT26i)

I gave up cm10 for stock. I just can't give up on bravia, album and modded stock camera.

But the stock phonebook and sms is driving me crazy :) I hope they'll get better in JB.

[Sony Xperia S, Acro S, Ion] reptile64:
I hope they will finally fix the contact photos! In CM10 it syncs all the photos from Gmail contacts in HD!! Unacceptable!!

Contacts and messaging app lagging for me too

When you say you are pissed off with the stock phonebook and sms app, do you mean that they are extremely laggy, and crashes frequently? Because that's what is my only problem area for my SXS. However, I have seen people who are having very less contacts (and not linked) to have SXS contacts app performing pretty fast. So I am not sure why in my phone the contacts and messages are lagging and crashing.

For the messaging app, the new leaked jellybean messaging is somewhat fast (it still crashes sometime though).
[Sony Xperia S, Acro S, Ion] alexferdean:
Re: {SneakPeek} official JellyBean for Xperia S (LT26i)

That's exactly what I mean. They lag all the time. CM10 phonebook is also heavy loaded but is blazing fast compared to stock. A heavy phonebook it's not supposed to be a problem for a dual-core phone.

Sure the new leaked phonebook might be faster, but it's not 100% stable yet and I haven't tried it yet.

I have high expectations from JB concerning phonebook, camera and BE working for unlocked bootloader. (I managed to get back BE, there is a post here ob xda for that)

A nice day to everyone!

The phonebook and dialer app are damn buggy, I've switched to ex Dialer.
[Sony Xperia S, Acro S, Ion] revan17:
Amen!
[Sony Xperia S, Acro S, Ion] topuji:
I have also tried several dialers like exdialer, DW contacts, Swipe Dialer, but what I feel that when the stock opens fast, ALL of the dialers are working fine. Sadly, when the stock is laggy, others also tend to be sluggish. Is it the same in your case also?

Re: {SneakPeek} official JellyBean for Xperia S (LT26i)

i think they shud really fix the camera. Its so noisy even in bright day light. It was much better in gingerbread. I hope jellybean fix this
[Sony Xperia S, Acro S, Ion] sagar023:
Yes but ex Dialer is much better, I've completely stopped using the stock dialer and phonebook. Dialing a call or looking up a no. in the phonebook took ages and was screwed up in stock.

it seems to be better...

nope.. we will be getting firmware 6.2.x.x.x (atleast from what i can tell so far)

well there is a Shooting Direction (up, down, left, right) in Panaroma mode... is this multiangle?

dont know abt picture quality...

687 MB user available RAM... with 394 MB free with the current firmware (this can change based on the # of apps running)

nope couldnt find any... pressing the menu button brings up the task manager...

nope doesnt work...

Re: {SneakPeek} official JellyBean for Xperia S (LT26i) [UPDATES!!!!]

Some framework changes... Mostly related to functionally which was introduced in newer devices...

I sure do hope so... Unless the study work load increase I will be developing for devices I have...

RAM consumption is surely going to be higher...

I think S should get the update soon... The firmware I am testing looks almost ready...

I ment menu button is there but no Google Now option comes up like the one in Xperia T... Check attached image

Nope... There has to be some noticeable difference between softwares too offered between two generations of devices... If Sony gives same software on both Xperia S & T then new buyers wont see much difference to pay a premium to buy the newer device...

when i get a worth while build with most of the function working/if i am able to get things fixed i will try n release the build...

sort of...

not an agreement but understanding... i dont get build directly from Sony... some users committed to seeing development progress for our device share them with me... without their permission i cannot upload it... its all based on trust...

a firmware ment specifically for developer devices will not work on retail devices... there is some sort of "hacking"/tricks which need to done to get these firmwares working on retail devices...

Also how is the quality of Photos and videos and will we get HDR?
[Sony Xperia S, Acro S, Ion] lee480:
I read online and from what I noticed, JB eats up more battery not because of Sony's fault.

JB has project butter which tripled the FPS causing battery drain.
[Sony Xperia S, Acro S, Ion] darkerm:
IF so then we Xperia S used will face battery drain problem :(

ICS is really battery hungry and if JB drain battery more quickly we will have to charge 2-3 times a day :'(
[Sony Xperia S, Acro S, Ion] Ambroos:
You have no idea how huge the process that goes into these updates is. Sony doesn't only have to maintain a base OS (which is pretty easy for them), but they have to make sure all their own applications (Walkman, Album, contacts and dialer, calendar, camera, messages, TrackID, Energy Saver, Back-up and restore, email, first-start guide, Timescape, FM Radio, Update center, Smart Connect, Films, the built-in keyboard and whatever I forgot) also work perfectly on the new version. AND they need to make sure the data from the old versions can be migrated to the new versions without causing problems.

Add to that that Sony never just updates software without changing anything else (like Samsung). Every single update Sony does brings extra functionality, something no other device manufacturer ever does. ICS brought us the new media apps and some extra Keyboard features. JB will bring us the new 2013 lockscreen and styling! That's the second major update that again brings a huge amount of improvements that will once again make your phone feel like a new device.

People should be happy with the way Sony does their updates. The things they add with every update (whether it's ICS or JB) are usually a lot more interesting than the things Google adds.

(And to the person who wanted the cyan icons in the notification bar: dear god please no, those things are horrible - simple yet elegant black and white styling is vastly superior, especially with the rest of Sony's skin design. The icons Sony uses aren't the old Gingerbread ones, those had more shading.)

Nice to see some screenshots for good faith.

I heard 4.1 is less buggier than 4.2 and 4.2.2 is an optimization of 4.2 with bug fixes. Is there any chance Sony will continue updating the Xperia S even after 4.1?

Well, FXP is already developing a 4.2 ROM for the XS. :)

Though it is not official jelly bean (oh btw, I'm already enjoying a stable CM10) as an enthusiast, it doesn't bother me that Sony couldn't care less for their old flagship users that they're pushing the update for us much later than their newer devices and in that process, they have lost a lot of fans, which includes me for the time being.

You know, you don't need new rooting methods to obtain root!

After you get a recovery (which you will be able to, as soon as one gets released)(and yes, you will be able to unlock the bootloader), you can flash the su.zip file. TADA! Root and Superuser, no flashing extra kernels or files or hooking your phone to a PC:
