When I rebooted my phone by update it shows message that process.com.android.phone unfortunately has stopped. Whenever I reboot the phone it shows the message.It can not allow me to access my phone even perform me to unlock my device. Some application like contact is also facing same issue that contact has stopped unfortunately and it can not access me into it. I used tool Sony Xperia Companion for software repair. Even I further physically contacted xperia care and report them about this but the issue is same. Now my device is out of warrenty. Please fix it as soon as possible.
