Hi, after doing hard reset or reformat your Samsung Galaxy Grand 2 will reinstall all factory default applications and remove all previous applications which installed from Google Play Store. However, for camera and browser will back to factory default as well.
I just installed the update 4.4.2 via internal phone procedure (about phone, software update - download, install).
Now the phone resets itself every 30sec.
I can unlock, but cannot lock.
It is just unusable - resetting every 30 sec. Looks like reboot, but does not ask for SIM unlock.
Any idea?
