What i mean by not using the mouse, is installing software on android to virtually use the mouse, so its as different as i can be from the normal mouse input. For the WPF part i was looking into the case if it has anything to do with .net core 6 or 3. or the interface was using webgl that could be used when making a gui. i have no idea if this is the case, but wanted to try different thing if this issue only relates to very few cases. i have now direct knowledge of how the 3D rotation is made and what components are in play. i am just a user and have wanted to call up some devs to look into this issue that has been ongoing for so long.
