I cleaned the app data from Gmail and noticed after a couple of times dramatic improvement in performance in the app. I would suggest doing the same to other apps which are backed up in the cloud, especially those that have been installed on your phone for a long time and have item on top of item written, some of which may be conflicting. Do this before doing a factory reset (especially since Helium doesn't work with this phone. Why Motorola won't fix this to bring it in line with other Android manufacturers, I don't know).
