Encryption not working

Encryption not successful.

Summary

The encryption function reboots the phone but does not encrypt the partition (on tissot and possibly other devices). There is also no clear indication/warning that the encryption was not successful.

Steps to reproduce

1. Install e-0.2-201811242083-nightly on tissot.
2. Choose "encrypt phone" in the settings. -> device reboots
3. Open Settings app again and check that it's not encrypted (you could do the encryption process again)

What is the current behavior?

Device not encrypted. No warning shown.

What is the expected correct behavior?

Either encrypt or clearly tell the user that (and why) the process was not successful.

Relevant logs and/or screenshots

There is an upstream issue and a workaround.

Possible fixes

change the partitioning (see workaround).
