For Unroot User:
1.) go to settings -> Backup & reset -> settings reset.
2.) after reboot, go to settings -> Developer options
- enable Force GPU rendering.
- off Window & Transition animation scale
3.) use Game Booster or android speedup booster.
You can find it on google play.
4.) For camera., user 3mp 16:9., the rest is off or default.
For root user.,
search on the internet., you can find tweaks, like turning on your bravia engine(even bravia engine 2), adding beats, change min frequency of cpu, set your start-up, moving you app and data in external sd., and more.,
don't use launcher or widgets., this app eat your ram a lot.,
for hd gamers, you can play it even unrooted., but you can play it only in single touch. force close of the game occurs when you try to use 2 fingers.,
last., use only beats in pimp my rom in google play and load it in cwm.,
you can find rooting and installing cwm in xda.
rooting your phone will void your warranty.
do not use custom rom so you can unroot again.,
real price is 180 euro but some stupid store sell it for 250 eur ... this phones is OK but people this is just PLASTIC nothing special !!!!

"SONY IS NOT SONY ERICSSON"
i just bought this phone for its battery rating and affordability. with regards to its lagging issues, i installed advanced task killer pro and observed that it's not that lag anymore. if you're not a heavy gamer or something like that, this mobile is for you. what do you except from a midrange smartphone, you'd better look for other mobile phones that simply suits your wants and expect the price that goes with it.
wizard, 16 Dec 2012i agree that this phone lags..can anybody explain why is it so?i could hardly make messages be... moreI am also facing the same issue...

Its a dust bin...
rockly, 15 Dec 2012This phone lags a lot Sony f***k. I will never buy Sony from next time.i agree that this phone lags..can anybody explain why is it so?i could hardly make messages because the response of the touch screen is to slow..
haiiiiiiiiiii............dudes can any 1 say how 2 mve the app frm internal storage 2 sd card
haiiiiiiiiiiiii.........dudes can any 1 help me how 2 move the app frm internal 2 sd card
The Xperia J specs with the slightly bigger screen don't cut it for me against the Sola, In Australia the J costs $AU205+ and the Sola $AU179 at the moment. Here the J is a useless release and surpassed in specs and price from within it's own family, how silly is that Sony!!!
reena, 14 Dec 2012hey any xperia users!!!!!!my phone ram is showing as 385 mb...either it's my phone defect or a... moreIt is not a problem with the phone its my sola shows same amount of ram. while specs says it has 512 MB RAM.
all those who r critisizin this phone remember..this phone is projected as a multimedia device by sony and not an epitome of processing power. Light multitasking is fine, but lots of open apps slow the device down..
That said, this device is great at what is was set out to do..be a multimedia freaks dream phone..yes..a 4 inch razor sharp display and awesome sound quality for 17K..quite the bargain. It plays video's beautifully and even though it has poor codec support, its video playback is nothing short of awesome.
Web browsing is fast and intuitive on the large display
and for heavens sake..when ur pals look at ur phone, they aint gonna see a 1GHz processor or a weak GPU
What they'l see is a stunning design.
Bottom line: Gamers..please look elsewhere..
Audiophiles and multimedia freaks...look no further!
I own the device btw..unlike many speculators out there only putting potential buyers off..
