My phone wont respond to any form of hard reset. Any suggestions as it would cost more to fix then replace my phone if shipped.
Also to give an understanding, my phone ran out of battery life and would not turn back on after i charged it. Responds to no reset options or computer hook ups. When power button is pushed phone rumbles once but is about a min after i push it, i know this is to long. The phone then illuminates the bottom menu lights non-stop and wont power down unless the battery is removed. My phone was updating the last day it lived. -.- please help if possible..thank you

hi, i’ve format my phone but then i cant use the mobile data. and all the applications are not up-to-date. how can i update them and use the mobile data?
Hi, at normal conditions, doing master format will make all setting back to the default. We assume that your GSM simcard is working, then the problem can be happen because the APN setting from your Sony Xperia J has already wiped as well. That is why you should try to make sure the APN of your Network provider already setup properly. See from Menu Setting > Mobile Networks > Access Point Names. If you are not sure about that, you should consult with your GSM provider contact center.
If your phone does not connect to Internet then all applications and data will not synchronize and will not up to date. If you are need to synchronize without GSM provider, then you should try to connect your Sony Xperia J with available Wifi near your locations, once the Wifi connected to Internet than all applications can update again, in some case you should open Google Play Store applications, and choose My Apps and press Update All button.
I’m using Xperia J,Camera quality is very poor in dark areas.Have u any upgrade version for camera,Very poor camera…
Hi, basically the camera specification at Sony Xperia J is not too bad. You can get good pictures at good light situations. If your location light is so low, then you can use build-in LED flash that already available at this phone. If your camera quality still dark, try to get in better light situation or at outdoor for getting better images. If you have already done some setting at your camera application, then you should reset it to default setting at your camera application and try to get the pictures again.

regards bibin
Hi, it seems that your Sony Xperia J internal memory already full or the capacity is not enough to install other applications. Some applications like Facebook or Twitter or BBM or Instagram or something like that will keep your data in the internal memory, some of that applications does not have options to move data to external memory, therefore after use several period of time your cached data will be bigger and make your internal memory size become full although you already try to uninstall or remove some applications. If this situations happen, please try to remove cache and data files from your applications, but doing this will make your data or setting become removed and the applications will run back to default again. You can clean the data by go to Setting > Apps and find the downloaded or any bigger data cache applications. Find button to remove or delete the application data.
