You need to use method 2 to upgrade the Xperia J to 4.2.2.
Didn't really notice a difference. Maybe the proximity senor got a little better.
Xperia j is bad phone in this price range because of some big corns...
1-Very old or back dated processor cortex A5
2-low ram 512 mb.
3-Camera performance is not good fumble in focus.
4-Low internal memory because you didn't allow to move your apps to ext card thus very limited apps or not able to install big apps..
xpria j upgtble jelly bean is vry slw.....main rsn is its prssr 1Ghz..
this phone design is elegant, the peformance not bad (just a little laggs but after upgrade.. laggs is more less), internet connection not bad( if you lost connection just turn off and turn on the mobile data)..
the only bad thing that this phone only has single core, so i think that is what makes this phone laggy..
Hi frnds shall i go for s duos or xperia j plz some one help me...
Im going to buy next week
i cant take a decision in this two mobiles which one is better...
hi i am CPU 1 GHz Cortex-A5. i am not capeble to take this phone. i can accept only android 2.3.6 maximam after that android need strog processor like Dual-core 1.2 for Android OS, v4.0.4 (Ice Cream Sandwich),and Quad-core 1.4 GHz for 4.2.2 (Jelly Bean) becouse the application too larger they need big processor thank you.........same Sony Xperia J
i can't surport this
worst phone ever.... i would have bought nokia 1100. no apps run on it...hangs everytime...i would request new phone buyers not to buy this phone....worst my friens also faced this problem/...

N my personal review of this phone is quite good..
I dont get any sort of problems on this phone..
Looks very beautiful..
The illumination light looks very pretty n is quite useful..
A little laggy but the RAM is enough for multitasking..
Lots n lots of apps compatible..
With the JB update works lyk butter..
Battery life is truely awesome..
I can use it for 2 days of normal use..
N if i use it just for answering calls n no data usage battery wud rather last upto 4-5 days..
So no issues related to this phone..
Price is quite reasonable..
Guys this phone is awesome as compare to samsung or lumia, having good battery back up, and is also not very costly...
the body design of this phn modle is also awesome....
This phone actually is a good phone.. but, the bad side fro this phone is the inter net connection.. if we don't get any signals, we will have wait for a long time.. once, i lost the signals, and i have wait a whole day until i get the signal back.. the negative side of xperia j.. hope sony will repair it
hey friends anyone used Sony's xb30ex earphone?? how's it's performance??
