You have many installed apps? And it has little memory or memory ram? If this is the problem, will have to root q, and if you have a class 10 card, move apps to the card, if it is a basic, just move the light apps that do not require a large perfomace I in here my xperia sp android 4.3, I have no problems of slowness.
I have helped and I deculpe by bad english

Cr*p Software
As you mentioned it is slow for it's specs, the hardware is still strong by today's standards and can easily run Jelly Bean, the problem is the software and what Sony have done with it. I also have slow performance on JB 4.3, I have removed much bloatware and installed greenify but still have poor performance (can barely multitask, opening 2 tabs in chrome will close Walkman whilst playing music ). The reason is mainly the kernel, the min-free (RAM) values are poorly tweaked hence we have low RAM and performance. Compared to 4.1.2 JB, 4.3 JB is a lot more resource heavier due to the added high end graphics support.

Hi there,
As you've mentioned above, I think there may be some software installed that are slowing down your phone. If you use the stock rom, you can try backing-up your SMS, contacts and apps(always remember to backup), then factory reset the phone('wipe') in settings-backup and restore.
Also you can unlock and root the phone for a better performance, but be cautious, for unlocking void warranties.

I don't have apps installed...but ok,Sony's stock ROM is ****...why CyanogenMod ROMs have many problems too??

You can try flash a ftf file with flashtool. It totally rewrite the system on your phone.

Unlock bl and try cm11.

1. Flash stock .207 with flash tool
2. Root it
3. install custom recovery cwm and then try some custom roms for locked bootloaders from android developement section

4.3 custom roms highly recommended for battery life

Yeah Sony's stock ROM for our phone is bad. CM11 (locked bootloader) is a million times better, no crazy battery drain, 400mb+ free RAM (will all my apps), very smooth. Its easy to install as well (no need to unlock your bootloader). Check this out.
Follow matsas's instructions as above but instead install CM11.

[Q] Questions about CM 10.1 for the Xperia T...

New Xperia T owner here (coming from an Xperia Arc S). Just got my new phone today and have been playing around with it. I had CM 10.1 installed on my Arc S and it was pretty unstable (rebooting all the time and whatnot). I want to install CM 10.1 on my Xperia T and I'm fairly confident it will be much more stable and usable due to the newer nature of the device. But I have a few questions:
1) How is the camera quality in CM 10.1 for the Xperia T? For the Arc it was downgraded due to a lack of JB camera libs, but I was hoping Sony had released JB camera libs for the Xperia T, considering how much newer it is.
2) How usable/stable is CM 10.1, in your experience? Any reboots, performance problems, other bugs, lack of functionality compared to stock ROM?
Mostly I'm wondering, will I lose any major features/functionality by switching to CM 10.1 from stock? Thanks in advance!
Here's some more general questions about the Xperia T:
1) If I flash a .zip file for a ROM, will that automatically flash the included kernel as well?
2) Does unlocking my bootloader wipe anything on the device?
Thanks.
1) Yes, kernel included in zip will be also flashed.
2) Yes, data partition (apps, user data etc.)

4.3 has the best performance for my phone :laugh:
I must admit that i'm finding 4.3 a little sluggish in comparison to 4.1.2.
I also think that there's less display options to play around with. I can't find a way of removing all lock-screen widgets. The one for the camera still appears even when disabled.
I'm also not keen on all the settings menus now being white as its very garish, but thats just a personal thing, and i'm sure I could get a theme to sort that out.
Not seeing any change in battery life, but thats not a bad thing.
I'm also finding that my internet browser crasher more now too.
4.3 is too damn slow
Don't go for the 4.3 update. wait a little time maybe sony will start to iron out the bugs because as of now it is unusable.
I recommend you stay on 4.1 a little longer ... maybe go straight to 4.4.
Forgot to add, the keyboard has been improved and once you get used to the change in predictive text it can be a lot quicker.
Must admit I am toying with the idea of going back to 4.1.
i am using existenz 4.3 rom, its like a butter... :good:
I have 4.3 and I am happy with this update. My phone is way faster, the apps are running and starting a bit smoother so no problems there.
The reported bugs; I HAVENT HAD ANY ONE ENCOUNTERD YET!
Yes the only one I can get is not working Bravia Engine2 but other than that is the update good.
If you are not sure what to do you can always come back to 4.1.2 if you want.
The link about flashing with flashtool can be found in my signature
Quick question though
Does the official backup and restore app works across android versions?
If I have backups from v. 4.1, would they will work in v. 4.3?
Thanks
if u a heavy user and prever stock rom, go for 4.3. in stock 4.1, memory management is main problem 4 me (CM/cm based rom is good memory management, but iam prever sony stock rom). im sure, if u not heavy user, u wont buy xsp . the only issues iam faced till now something my xsp out of memory like this, no solution except reboot (sorry 4 my bad english)
@warok88
I have this problem too,but few days ago i find solution and fix without root!
I like 4.3!
Miui , android 4.2.2 - old, but best if u dont playing 3d games
I´m using 4.3 with DooMKenel and I don´t have problems with ram or freezes, and you can use roms like cyagenonmod for android 4.4.2 or eXistenZ Ultra if you want a rom based on stock firmware

none..wait for .205 firmware and let's hope that many bugs will get fixed..and btw, it freezes when you wipe cache but if you wait will move on
I should not buy this phone
Maybe I would have bought an iPhone 4S or Moto G.
.201 is working well enough for me. You could try disabling apps you don't use or flashing again.
As for the keyboard, you could install another one. I find Google Keyboard to be very smooth and responsive.

[Q] LG 4X HD serious lag problems

My LG 4X HD was running 4.1.2 JB and using Optimus UI. Using it daily, I experienced lags in occasions such as: entering app drawer, presing the home button while running some apps, unlocking the phone etc. So I turned off animations, device was suffering lag less often, but still it annoyed me. I decidet to install CM 10.1 hoping that lags will dissapear, but nothing changed dramitacally. Phone runs smoother now, but it's still laggy(Animations turned off even now). I have installed cca. 10 apps on the device, and it shouldn't be a big problem for device with quad core and 1GB of RAM. Any ideas what could it be?
I had same problem with lag all around on 4.1. I had best experience in v10f, that is android 4.0.
my suggestion would be flashing original KDZ first and after doing so wipe it clean before attempting to flash custom roms. 4X has 4 cores and 1 GB ram should be able to handle multitasking well. Help this helps.

it's embarassing how lg doesn't support this phone that with the jb update is full of lags. I've installed cyanogenmod with yodak kernel. Now my mobile phone is a Ferrari
I for myself think that stock ROM (V20B) + iodak kernel v06 is the best combination possible for a good balance of performance and battery life.

Stock 4.1 vs Stock 4.3

im on .207 and im thinking go back to 4.1 .254
which is better?
i have a long time on 4.3 since .201 and i dont remember 4.1 perfomanence.
thanks
Do it!
I've used every stock 4.3 rom. Was very excited when it launched.207 is the best 4.3 rom,but for me after a while it starts to get slow,launcher redraws and everything and i decide to go back to .254. It was a GREAT decision,performance and ram management is far better than on 4.3,phone is much more snappier,and i like the interface design better than on 4.3.The only thing to me that's better on 4.3 it's x loud. Its louder than on 4.1 but not by a much.
I have 4.3 207 and its ultra slow when i open wifi, fb and messenger are ultra slow , and lags and phone hangs alot , rrally neef help, the phone is ltle smooth offline

Do a nandroid backup, try slimkat and see
If last slimkat avoid access to sdcard, try slimkat 8.8.
If there is any problem, you can restore your nandroid backup...
So for no problem, you can save nandroid backup on pc
Stock 4.3
From my experience I can say the following...
In regards to 4.1.2 (stock):
+ Virtually bug free.
+ Smooth performance (good free RAM).
+ Exceptional battery life.
- Poor Wi-Fi range (only bug I found).
- Okay camera.
In regards to 4.3 (stock):
+ Great camera.
+ Smooth performance.
+ Receives media app updates (not sure about 4.1.2).
- Poor RAM managment.
- Uninstalling app graphic glitch/lag (can be fixed with replacement packageinstaller.apk)
So I personally would stick to 4.3 (I fixed the package installer) and am a light user so RAM doesn't bug me too much, the Wi-Fi issue on 4.1.2 was the only issue but killed it for me, otherwise 4.1.2 would've been perfect.

Yeah, that ROM is very popular and for a good reason-yet to try it though, I will wait till I am bored to death with stock ROM. Relating to the op, I don't like the feeling of being on an older android version when a newer version is available, hence another reason I'm on 4.3.
I also see you'll be selling your SP (sig), may I ask why?
After countless flashes I've decided there is no better firmware/rom available than the Stock 4.1.2 (.254) for this phone.
I don't care which android version it runs as long as it runs smooth and fast.
