I have yu yureka android device which has octa core snapdragon 615 processor, 2GB of ram, 16GB internal storage.
Recently I migrated to snapshot release of Cyanogen Mod 12.1 (android 5.1) plain without any Google Proprietary Apps.
I thought of using device encryption feature. There is no lock screen password/pattern set. There are no secondary users. There are no so many apps installed. My /storage/emulated/0 doesn't contain any media files (completely free).
So, I entered
Security and selected
Encrypt Device . It showed some boot loader icon for a couple of minutes and then Settings > Security showed
Is it really encrypted, since it took very little time and not having lock screen password. The device was fine on rebooting.
Then, i created 2nd user and protected it with lock screen pattern. Then rebooted, device was fine.
Then I created lock screen pattern for the 1st user (Owner). It prompted to ask for this pattern at device boot up and I selected Yes. I then rebooted the device. At first, it asked for pattern, I entered the 1st users lock screen pattern. Then the device rebooted and was in boot loop now (continuous boot loader animation) for 45minutes.
- Was it encrypting the storage now or the process of encryption somehow corrupted??
- Did I not do the encryption correctly? Is it must to have lock screen pattern before starting encryption?
- The device is relatively faster and I guess it should not take so long for encryption. With my device specs how long can encryption be??
- I have a 32GB external sdcard formatted with fat32. Is it going to encrypt that as well?
- What happens possibly if I pull out the battery, apart from loosing data?
