Odd Textures

I’m using Unity to develop a game, but my terrain textures come out pixelated. I’ve tried disabling Mipmaps and lowering the quality, but ONLY terrain textures are affected, and nothing I’ve tried works. This doesn’t happen on my Note 3, same program. I can’t post pics right now, but I will when I get the chance.

Here it is. I’m showing it next to a tree to prove that this bug doesn’t affect the bark texture.
