120hrz for Android?

With the new Razer Phone coming out, is it possible to make a 120hrz version of my game so I can use the Razer Phone’s 120hrz display? I know you can change the MaxSmoothedFrameRate in defaultengine.ini but does it affect mobile apps in any way? And would this cause problems if I were to install the same app but on a phone with only a 60hrz display?
