White icons (as if lack of memory)

I get white icons in my screen, as if you know how when I'm having lack of memory sometimes graphics mess up?

Anyone know how to fix this?

Maybe try clearing cache data and see if it helps?
My game runs perfectly fine on my device with 1GB RAM(Android)

P.S - Try using Imgur to post pics!
