I´m aware of the limitation that seem to be in orde to remotely control a Moto C due to some manufacturer limitation.
After performing a factory reset to my handicaped brother's Moto C, running Android 7.0 and reinstalling Quick Support 14.2.130 that I frequently use to help him, I have noticed that not only Remote control remains without working and only viewing is possible, but also a very useful "pointing hand" that was available before is no longer appearing.
I would like to kwon if there was some pluggin or add on required to have this usefull feature, that helped me providing better assistance to my brother. Even though seems that the ideal remote controlling feature will not be available for this model, it was very usefull to have the possibility to show him where to click, with this this sort of "pointing hand" that I was able to control from my phone or remote desktop. For some reason, is not appearing anymore.
Thanks and regards for your support,
Esteban
