I am posting here in the hope that someone has more information on this, or that this information is helpful to someone... Late last week, my phone started similar funky keyboard behavior. When I am in the SMS app, the keyboard now remains on top if I try to open the menu items. Certain items that require full screen to display properly are unusable now. Seems to be the same no matter what app I am using. If I try to open the menu in Facebook It's not visible under the keyboard. I have used Clean master for about a year, and it appears as if I just got the new version with iSwipe. I do not care for the feature and have it disabled, but it also annoyingly keeps prompting my to turn it on. I thought perhaps Samsung had updated the keyboard, but am thinking now it may be Clean Master... Thoughts anyone????
