This is a very cool thing to have, conceptually, but I have just one major issue that hinders it's usefulness. I use a stylus to navigate, and this does pick up the motion of my stylus hovering over the screen, but there is no way to set the input method to allow swiping as click+drag, so it feels quite unnatural. Are there any plans to implement this?

There in fact should be a way. Try switching to one of the other Input Modes (menu while connected -> input mode -> direct hold pan. This mode will reverse what long tap is used for and will give you direct drag/drop capability

This VNC viewer works very well. I'm able to use any program on my PC with no hassle, which is great. One issue that I've had is that sometimes the screen will become half covered with a transparent white overlay while I'm using the VNC. I think the root of this issue is the Alt-Tab keyboard shortcut as I'm using a hardware keyboard with my Tab S4. Besides that one small issue, which doesn't really inhibit my ability to work much, I love this VNC. Props to the developer for creating it!

Thanks Kris! I am not sure about the Alt-Tab shortcut issue you mention. If you think this is an issue with the app and not something your Tab S4 is doing, please get in touch by email or open a bug report at

I'm using via a Chromebook and using it to control a dedicated video editing server. For that I needed fairly fluid response. Even going through wifi+router, I'm getting nearly equal framerate (24fps) to the host machine (whose monitor I viewed simultaneously. Combined that w fact that this is the only app tried which displayed error msg WITH CORRECTIVE ACTION, I'm sold. Nicely done!
