Why when someone sends me a picutre is looks grainy on my phone but not theres?

[AC Question]

I received pictures in my messages and they look grainy? Ill print them and the pixel looks terrible? But on there phone picture is perfectly clear? Could it be a setting on my phone? I take pictures and they are clear?

Welcome to the forums. Has this happened with multiple pictures, or just this one?
