Dual core A9 with 1GB RAM, like Galaxy Grand, is already enough to have above average performance in FB.

anyway i also suggest to get xperia m instead if they prefer better performance but again xperia j is not a bad phone.

ray, 12 Sep 2013yap smooth ui, yap smooth web browsing, not so smooth in fb app(average) btw its a good phone.I still suggest everyone who doesnt already own a J get out of here and stay away from Xperia J at any cost, the Xperia M is so much better that buying a J now is a crazy thing to do, ultimate waste of money.
I know how single core A5 performs in Facebook app, if you call that "average" then your definition of average need to be questioned.
JS, 30 Aug 2013For anyone considering buying Xperia J or any smartphone from Sony: This is the worst produ... moreWell you expected iPhone performances on xperia j,lol xperia j is 4-5 times cheeper than iPhone,you are apple user and you are learned on apple smoothness.All issues you are having are ridiculous i have that phone it's on JB when it was stock everythong worked just perfect except subway surfers that game laggs a bit but everything else works just fine for a cheep phone like this,no issue with setting alarm or any kind.Now i'm using custom rom it's based on stock jb it's a little better but still have locked bootloader so no oc.All i want to say is you are expecting for a cheep phone like this to work like dual core phones.Sony made a mistake for not giving xperia j a GB rom i have xperia arc on gb it runs so perfectly smooth.In xperia j the bigest problem is ics/jb felw does two fw are not made for low hardwares.
this phone works very smooth... but before u going to do any tasks clean the ram and use... I don't have any lagging while playin any game like subway surfers, temple run and some other gud games..... love my phone.... use clean master to clean ram and u can download it from google store....
Maaz, 06 Sep 2013is anyone using 16GB mmc with this phone?? if yes then pls tell me how it works.. Is it normal... morefrd,u can use 16 gb micro sd in this phone it`s work properly not any hanging problem but this phone slow
