Quickly pass the cell phone on to a friend? Then block apps very quickly beforehand in order to avoid embarrassment!
Who does not know it: You give your cell phone to friends to show something - and suddenly you are in some apps where you have no business. Whether it's your favorite messenger or your email program, apps like this usually contain private content that you would like to keep to yourself. But don't worry - by locking apps, sensitive information can be protected from prying eyes.
