I see, I'll give that a shot.

I'm not sure how to do that. Could you elaborate further please, regarding the steps? 

Can I play under one account on a second device? My current smartphone I'm playing on is a little old and lags a little, but I've another new phone. 

However I don't know if I can transfer my ongoing game account progress to the second device, if I install the game there.

So does anyone know of a way to transfer their ongoing account progress to another smartphone, so that we can continue playing there instead of having to restart all over again?
