Is it random? Does it just give you the "Unfortunately, Google Keyboard has stopped" message? I've been using Fleksy for the past few weeks, so I can't say that I've noticed ...
Thank you! It is random, no message. The keyboard will just stop in the middle of me typing. It goes away. A reboot fixed it, but it's very annoying. I still haven't wiped the cache partition. I should do that. :/
