Doesnt load...

So I love Minecraft...but whenever I get into it, it takes about ten to fifteen minutes just to load it. I know this is not just my phone because my sister and a few friends have the same problem. We have different phones AND devises. So, it is in fact the game. I gave the game two stars because the loading period is ridiculous. Also, when my phone sleeps, and I dont notice, I have to RE LOAD. So I end up never playing because its such a drag to load. If this could be fixed it would be SIX.STARS.
