I would like to purchase a Samsung Galaxy S6. One of the main reasons for the choice of device is the (apparently) good fingerprint sensor. I would like to / have to encrypt my phone (my employer requires this but, honstly, I would do it anyway) and I am very tired of typing my PIN every single time I want to unlock my phone. Hence a fingerprint sensor is a must-have on my next phone. Here are my questions Google could not answer for me:
Is it possible to use the "unlock with fingerprint" feature with an encrypted phone, or is this authentication method considered too weak? Strangely there is no information about that.
I would like the phone to behave in the following way (like an iPhone 6): After booting the device I am asked for my (potentially complicated) passphrase. After that I am allowed to use my fingerprints to unlock. After some time (configurable, maybe some hours?) I would be asked for the passphrase again.
Benefit: Convenience through the fingerprint unlock, increased security because if somebody tried to force me to put my finger on the sensor (or had a rubber copy of my finger) it would still be no good on a freshly rebooted phone or after some hours.
Basically this means having two unlock schemes configured at the same time, fingerprints and passphrase/PIN. Former would be used for convenience, latter for security. Putting in the passpharse a few times per day would be perfectly acceptable to me.
Is this possible with a Samsung Galaxy S6 with stock ROM?
