In the lock screen, able to change the sound options to mute the phone without any pin or fingerprint where as the same is working fine if someone tries to power off the phone. Changing the sound option to mute would be first thing the pick pocketer will do in case of stealing mobile. There should be zero function operational on lock screen for security reasons. Even shouldn't able to scroll down and see the buttons order and status. At least we need to have full proof security to avoid such high tech expensive devices frm theft.
