Glitchy Textures on Game Objects

So I'm working on this little camping game for the Gear VR. I've been having this issue where textures on game objects from certain angles or distances get glitch looking. There will be Some things that look fine, and others that look glitchy. I've messed around in the render settings,and cant seem to find anything to fix the problem. I have an image of what it looks like. (its using airdroid so the quality isn't very good)

Thanks for any and all help!
