As I still know no better place to report issues with Patchmanager Patches, which have been solely released at Patchmanager's web-catalog:

@jakibaki, your Patch Back-Button Gesture for Android-Apps does not work as intended, anymore: It switches to the home screen (i.e., puts the foreground Android app in the background), instead of triggering an (emulated) press of the Android back-button.
The original back-button is working fine, though.

Observed on an Xperia X (with its AOSP 4.4.4 based AlienDalvik) under SFOS 3.0.2 with Patchmanager 3.0.57. As I have not used this Xperia X much early this year, this issue may have appeared under SFOS 3.0.1 or 3.0.0, already (but I missed to observe it).
Side note: Back-Button Gesture for Android-Apps 1.0.3 is still installing and applying fine under SFOS 3.0.{0, 1, 2}.

In contrast to that Back-Button Gesture for Android-Apps 1.0.3 is working fine on a Jolla 1 (with its AOSP 4.1.2 based AlienDalvik) under SFOS 2.2.1 with Patchmanager 3.0.57.
