iphone 6 plus screen stuck on a yellow loading screen

I was using my iphone as normal and then it went to the white screen with the black apple logo you normal see after turning your phone back on. At first it looks normal then appears to freeze on the same loading screen and then the loading bar appears and suddenly disappears and then shows an obvious yellow tint to the screen. Anyone know how i can get my phone off this screen? (in person the yellow tint is a lot clearer, but you can see the difference between the white screen to when it seems to be loading data to then being froze)
