  • My s3 was working fine and fully charged, when it decided to turn off on its own.
    since then I have not been able to fully turn on. I’ve tried plugging it in the wall charger… Nothing…
    If I press against the battery it will vibrate then turn on then shut off.
    I love this phone.. But does it sound like its a housing issue?
    I don’t want a new phone, I really want to fix this one.
    Thank you for taking the time out to reply

    Hey I’ve had an s3 for a year now and it was fine until a couple days ago it started rebooting itself…what I’ve noticed is that when I’m looking to something that you have to scroll down a lot like Twitter or Facebook suddenly the screen stars to idk lost power and it looks like when you’re watching tv and the light goes out….so than it reheats and shuts and then it’s like I have no battery but when I plug it to the charger and turn it on it says like it’s 40% loaded sooo…so wired. ..what is it?..thaks!! 🙂

    • It is the clear case that you are having battery problems in your phone, and you need to change that, but before that I recommend you should update your Firmware and Software, as the software issue could also be reason of this problem.

    Since 1 year am using SG3. without any problem, 1 week back i updated my android 4.12 to 4.3. after that i can’t connect USB cable with system, and mobile is not charging while switch off. i updated by Wify connection only.
    so please tell me is it because of any updating error or some settings problem.
    if it is problem of android 4.3, please tel me how can i change to android 4.12.

    • Well this could be due to any of the reasons, but if it happened immediately after that then it must be due to android update. I recommend that you should take the back up of your phone’s data and do a factory reset, this will do the job for you.

    Can not be rebooted , took the battery out and put it back still the same .when turn the power on the samsung loogo appear and stay still

    • Ali that’s hanging problem, not charging problem. You have commented on a wrong post my friend. Anyways if it hangs on the logo then none of the software solutions are going to work in this case. Please check whether any of the volume buttons are jammed or not, if they are then replace them (from hardware). Else the problem will be that the display pins are short with each other, you need to clean them first. If that doesn’t solves the problem then you need to re-solder them. Hope it works for you.
