Click apps cannot be run from Android, sorry.
If your only problem with UT is the flashlight not working when taking pictures, I'm happy to tell you that this problem is solved in the new Halium 7.1 port of the FP2, by @peat_psuwit. This port isn't pushed officially right now, but can already be installed. See this topic to install the Halium 7.1 port (you will also need to install gstreamer-droid to have the flashlight working).
However, please wait a few days before doing that installation, the core devs actually are upgrading to Qt 5.12 so you should not use apt at the moment. See this topic to know when things will be back to normal.
