Android transferring game saves

I am about to get a HTC One M7 and yes I know about the Camera issue so shut it, I hardly ever use the camera anyways. I am grabbing it off some guy for 150 AUD, pretty cheap....... as in I am also getting a wallet case with it so it seems a good deal just one thing how do i transfer my saves of Deemo and Cytus on my current phone onto the HTC one and by the way the HTC One is running Insert Coin.
