I have a 3rd Gen Moto G that I just enabled encryption on. It showed the warning as usual, "make sure it's plugged in, this will take an hour or more", etc. However, after confirming this, the phone rebooted itself, asked me for my pin so it could "boot android" (even though the boot splash screen had already displayed), and then showed me my home screen.
The issue: this whole process took less than a minute. Now, granted, the phone has only 3 lightweight apps on it (aside from the not-very-bloatware-like stuff motorola put on there), plus android standard things. There's also a few albums of music on the 32GB SD card; perhaps under 2GbB.
Less than a minute is not an hour or more. Did the encryption actually happen? The device THINKS it is encrypted; it tells me so in the settings menu. If not, what next steps should I take?
This is android 5.1.1.
I just came across this right before I posted: Device encryption fails, but no error
My device IS plugged into a computer, but through a power-only cable. There is no data connection. Not sure if that matters; I'm not sure I can do anything about it anyway, because the phone says it is encrypted already.
