I have installed Swiftkey from Google Play and select it as the input method but after a few hours or so the default keyboard is selected again. I can't seem to make Swiftkey the default keyboard permanently. Anyone else run into this?
This might be your issue?

Supposedly only on updates...but it wouldn't shock me if the behavior happens more often than that....it's called a bug for a reason.
Interesting. I wonder if that is the issue. Is anyone else having this problem with other 3rd party keyboards on the M8?
I will have to see if there is a way to convert it to a system app.
