I'm using the same app for months now and havent noticed that it would be responsible for hogging the adb connection channel.
Its much more likely, that the app you used to push/install it hasn't exited the adb session cleanly (apps2fire for example is notorious for this behavior).
Anyway - sometimes, although very infrequently *some* app hogs the adb connection in my case as well - in those cases I have resorted to https://play.google.com/store/apps/d...txapps.wifiadb
to toggle adb off and on again. (root required) - because its a bit faster than to do the same via the built in adb toggle Amazon provides.
So - at least its not normal for the "Rotate Screen Orientation" app to block the adb channel on a regular basis, in my experience.
