I have updated the FAQ on Post #3 to include the info on TX's different screen technologies.

It is clear that the 'b' version OptiContrast has a better viewing angle.

Sony never wanted to admit this, fear that all the 'c' owners will complain to them.

It is actually hard to choose, even if you know about the SERVICE menu.
You cannot just go to into a shop, ask them to open every boxes just for you to check the SERVICE menu.

Unless you found a 'b' demo unit, and you insist you want that.

This helped me:

Xperia T got Ubuntu Touch support:
https://wiki.ubuntu.com/Touch/Devices#Sort_of_working

Sort of working...but when it's finally working, should be interesting.

Not yet. Ubuntu Touch just starting to take off. We will need to wait until Valve Software make Steam for Ubuntu mobile.

No update is available yet. Wait until March.

My TX with casing. Pictures taken with my old HP (5MP only ).
This is the same casing AmeiN is having. When it come to casing, TX don't have many choice.

No Air Gap/OptiContrast both means the touchscreen is optically bonded to the LCD panel.

But it is obvious that the 'b' units has some improvement on this technology which gives better viewing angle.

No point checking with PC Companion. New firmware not available yet.

How frequent is the SOD? Many times or just once?

T, TX & V were released at the same time. Besides the different hardware drivers, they all shares the same set of Sony firmware & software.

There must be some similarity between users who have experienced SOD across T, V & TX. Maybe they all installed a certain apps? Maybe they all use the phone in a certain pattern?

One way to find out is to list out all the installed apps in the phone. Those that does not come with the phone, was installed from Play Store or thru apk. Then do a comparison.

Then this is confirmed something in the Sony firmware.

Well, the SOD seems like gone with JB update for V users. So, I think the JB update for TX will also fix this.
Have to be patient a bit and wait for the update to come within March.


In the mean time, you can suggest to your friend to change a bit of his/her usage pattern. Changing usage pattern may avoid this SOD problem. Usage pattern means how an user interact with apps in the phone. Just some examples:

1. After using an app, some users always press the 'Back' button repeatedly until back to home screen,
While some other users like to just press the 'Home' button to go straight back to home screen (the iOS way).
(There is a difference in this, but it is technical. So I wont explain.)

2. Some users always like to go back to the Home screen before letting the phone sleep,
While some others just press the power button to put the phone to sleep after using an app.

3. Some users like to put a lot of icons on the home screen. Full of icons & widgets,
While some others want to keep the home screen clean, just a few icons + a few widgets.

4. Some users like to charge their phone whenever there is a power outlet nearby and they are not using their phone,
Some users like to charge their phone routinely at a fixed time everyday,
While some others will only charge when the battery dropped to a certain level.

A certain combination of these patterns may trigger the SOD inside the Sony firmware.

Sounds strange right? Just my thought.

I do not know the exact cause of SOD, so I cannot tell you how to prevent it. I am only suspecting that some usage pattern + some phone settings will trigger it.

For me:
1. I always use the 'Back' button to return to home screen.
2. I always return to home screen before I let my phone sleep.
3. I only charge my phone when battery is at the 'red' level. Somewhere below 20% or when it prompts me to charge.
4. My display sleep time is 30 seconds of inactivity. Extended Standby Mode off. Only WIFI on at home. Using a pattern to unlock. All Developer options are off. Other settings are mostly untouched.

This is just my usage pattern. I did not follow it 100% all the time, just most of the time. Most importantly, you have to understand that this is not the 'best' way in using Android. Android is very flexible, it will work in whichever way you use it. It is just my suggestion to change the pattern a bit to see if it helps.

I owned a TX for 2 months and I never encounter any SOD so far. SOD rarely happen on TX.
I do not have any special app. Just normal apps like anyone else: App2SD, ASTRO File Manager, Whatsapp, Gmail, Facebook, Compass etc...

What you have seen on a tablet is a 'task killer'. Since Android 2.2/2.3 onwards, it doesn't need a task killer anymore. Your friend's phone is a clean unit, there is nothing to 'kill'.

I dunno the exact date of when JB will be available. From all the info on the internet, we only know that it will come by March, but dunno which day of March.

I will definitely upgrade if JB is available. The PC Companion will download and install for you. All the apps and data should remain there after the upgrade. As a precaution, you should always do a full backup before updating any firmware, just in case.

I didn't turn on the Extended Standby mode because I want to receive Whatsapp message and Gmail notification when my phone is in standby.

Can try TeamViewer. Easy to use and works across firewall.

Of course lah, that is a Nexus. There is a reason why Nexus series are the first to get latest firmware. Because they are using the vanilla Android, without any customization. Everything are there, they just build from the source code.

For Sony, they need to take the JB source code, add in their own drivers, customization and extra apps. They need to do more testing than Google. That is why every manufacturers are slow in delivering the new Android firmware.

Yeah, custom ROMs are here.
But, some people don't want to unlock the bootloader yet.

The FreeXperia (FXP) developers do not have a TX unit for their own dev and testing. They have to rely on testing and feedback by other TX owners. That is why not much development on TX.

Better GPU is good for gaming. If you don't play game, its just the same.

As far as I know, there is no one using TX custom ROM in this forum. Everyone is waiting for the Sony Jelly Bean update.

And I suggest you don't flash T ROM on your TX. It won't work.

CM (FreeXperia) and AOKP (KangXperia) are 2 of the well known ROMs out there. Others (like MIUI) don't support Sony phones.

Just week 13.
I am backing up now... Will update soon.

Status report anyone? Anyone stuck at update?
