It lags on every other phone except for Xperia which has a WebGL and the game there runs with no difficulties. I've seen that many people suffer from this problem. So, what should I have to do to make no difference in playing from Xperia and other phones.
I have followed the tutorial in the link MPPlantOfficial gave me, but my project still lags.. I've removed 75% of the objects on screen just to test it out, and there was no change in the performance (so, something else is the source of the problem), it still runs by 1 frame per sec.... 0_0
