I have a brand new Galaxy S5 with Kitkat (4.4.2) and am required to encrypt it for work. I greatly prefer to use the PIN lock screen instead of the password due to the annoyance of having to type in the password every time you want to check your phone.
My phone will ONLY allow me to choose "Password" for the lock screen type when I go to encrypt. However, my friend has the exact same phone as me, and is able to select both "Password" and "PIN" (whereas mine is grayed out and says 'Turned off by administrator, encryption policy, or credential storage').
I have restored the phone to its factory settings, and there are no 'Device Administrators' or user credentials installed.
What exactly has caused my phone to no longer accept the PIN? Was there some update to the security settings? Is there any way to restore the PIN functionality?
To be clear, I am not asking about separate passwords for encryption and unlock, I know that this is an Android issue that has not been addressed by Google, and I am not looking for Pattern, Swipe, or None, which don't work with encryption on any make or model.
