Oh, phone case. You had me very confused.

I dunno, I just use otterbox cases. Because they never give up.

Probably dbrand

I'm a certified dbrand shill, so I would say just buy a grip case from them and call it a day if you want high quality

I don't know what sponsor you mean, but my Spigen SlimArmor case has little bubbles in the inside of the corner so it can squish more in those areas
