I use my FP2 with a SIM at slot 1. Slot 2 is empty.
The SIM card is protected by a pin.
I installed an third party lock screen (HI Locker).
After a reboot the third party lock screen overlaps (I think so) the unlock screen for the SIM card.
The unlock of the FP2 is successful, but I did not found any way to return to the SIM unlock screen or to unlock the SIM otherwise.
Now I’m using the workaround and use the SIM card without a pin.
I unchecked the Privacy Impact box, but the problem is persistent. At the moment I only see 2 options: disabling the pin protection (like bathel did) or uninstalling the app. Any other ideas?
