Hi, thanks for answering my question. But I tried doing that. After i rebooted the phone, nothing happens but the apps in my phone keep reappearing. I tried to delete the apps but the apps reappear after reboot. I tried to install some things from play store, but the apps disappear after I rebooted the phone. I can't set the default installation location to my sd card. I tried using Link2Sd but still doesn't work. Actually the real problem is that I think my internal storage ( usb storage ) is read-only which is where all the apps which won't uninstall is at ( not sure ). I also think the usb storage is damaged or something. I don't really know what is the problem.
