[rajkm008]

it's usually happens problems like heating, lagging, screen freezing, battery drainage when we update our device to the newer os version or security patches,do the wipe cache partition or factory data Reset once (create backup your data before resetting). Visit nearby Samsung service centre and ask them to reinstall the operating system or Wait for next software update,....
