I have a Kyocera Hydro Icon C6730 smart phone running Android 4.4.2 and several months ago, I believe one of the app's updates made it so that it no longer works on my phone. The big rectangular button to update now is unclickable. I can tap it with my finger as much as I want but nothing happens. I can force an update but only once. If the database is out of date a second time, I have to open my phone's settings and click clear MalwareByte's data and cache before selecting force update again but that makes it so the app thinks that I've never run a full scan.
