What I'm looking for is for an app that lets me use my phone as a mouse to control my tablet. Thing is it has to be over the internet and not wi-fi.
Think of an app that works like blueputdroid but connects like tablet remote, does something like that exist?
Tablet Remote would work in most cases, but I'm mainly trying to navigate game menus with my phone, since although many games support a gamepad for some reason developers never thought about controlling menus with it too. And I can't use bluetooth cause sense roms have a borked bluetooth stack, and AOSP roms have terrible battery life in comparison.
