This is worst phone i have ever use, low Ram, not enough phone space to install apps, it's a very slow phone.
it has too short memory storage as you cant install important apps. except 2 or 3. and after these apps has installed their updates causes slowness to the phone u feelto much difficulty in your currently running apps.so plz dont buy this phone
DO NOT BUY!!!! Extremely bugy, after 1 to 2 months the lag became unbearable even though i was using extremly carefully as i was worned there were problems.
DONT BUY THIS PHONE. This phone was great when you first get it, works well. after a couple of months you constantly have to be updating apps that take up a lot of space and you cant delete. Then if you don't update, the phone will slow down so much it won't work when you try to work it then because it wont work you might press a button and BOOM! the phone is frozen and then it'll restart. Unless you have amazing MB, the phone will be worth nothing. The only good thing about this phone is this dont break easily.
Its "WAS" a great phone with sleek curve design and scratch free back cover.
I never complain about its slow speed.
if you buy a phone with approx 380 MB RAM and complain about its speed
what make such sense lol
I have already samsung galaxy core prime but i also want to buy it for a second one.Should i buy it or not?
I got one little over two years ago.
At the beginning I loved it.
Apps started crashing.
I might have some virus or so, it's running really slow, even after using Ccleaner.
The usb cable never kept good contact when recharging, so it usually ended up ruinning the memory sd, and I never got to use the phone as usb or... idk if one could ever do it anyway.
Nowadays I cannot understand anything people say on the mic. All my phones ended up like this. I wonder if it's my faulty use or if it's the weather or the materials are bad (might be all 3?).
I'm wondering for a phone, same price range.
Mine's still got, just not as a phone, but as a mini tablet kind of deal, yea :)
Anonymous, 25 Jul 2015 Hi, I have used Sony Xperia J for one year but is running slow what should I do? Do what I did. By another phone and break the Xperia J.
My xperia J screen became black although touch is working as I can receive an incoming call. Downloaded and repaired the device s/w but the problem continues.
Looking for a working solution..
