Hi, I have the P10 Lite. When I first got it, there was a handy camera icon on the lock screen so I could access the camera quickly. Daughter decided to change all the wallpapers and I cannot get the icon back on the screen. I have been through all the menus/reverted to original wallpapers etc etc, but I cannot see how to activate it again. I know pressing the volume button will do same job but I find that too fiddly. Help!
