If it becomes the case that my phone is stolen, I would like to make it as difficult as possible, if not impossible, for my data to be accessed without my permission.
I understand that Android has the ability to perform a full disk encryption on my phone. However, I also understand that the disk is decrypted on boot. Which means once the phone has successfully booted, the encryption is no longer applicable.
Personally, I tend to keep my phone booted at all times for convenience reasons. This seems to imply that my phone will therefore be decrypted at all times. Given this situation, are there still any benefits to encrypting my Phone? Additionally, would encryption help me at all in the case of theft? If not, are there any alternatives to protecting my data from theft?
