Anders_ASUSi locked the phone and unlocked it again(i missed a comma there....so it looked like i unlocked every app
When you say unlock every app, do you actually mean that you kill them and then restarted them again?
I'm assuming it worked after this? I didn't get if you actually restarted the phone of if you only restarted the apps. It's always good to restart your device when something like this happens.
If it happens again repeatedly, then you should first backup and reset your device. If you're still getting the same issue after this, then please contact your ASUS Service Center
