For the case I use the cheapeast TPU case I could find. It has a lip over the front, so I can put my phone face down without worry.

My phone is still going strong after a year and multiple drops. The case is a bit yellowed though.

I didn't order on Amazon but this looks identical : https://www.amazon.com/S7-Super-Thin-Lightweight-Absorption-Protective/dp/B01B4CVDD0/
