. go to safemode and observe is there same issue in safemode too
if not then problem may due to other downloaded apps
and if same issue in safemode then try to visit service centre

steps to turn safemode;
long press on power button>
long press on power off option>click on safemode >your mobile will restart and turn into safemode.

uninstall cracked apps you installed recently. A series has Knox security can't get hacked. if you have still some doubt do factory reset
