Lol, and I would only use clear cases when I was an android user. But, they scratch and yellow over time, they all did for me. And yes, the otterbox will discolor and scratch. The tpu portions of the case will yellow as well. I think the only case that doesn’t yellow is the speck presidio stay clear which they will warranty if it does.
Ahh former Android addict myself here who went to the dark side lol. Yeah that is exactly why I never use them, due to yellowing. Speaking of Speck tempted to get a Presidio grip, but man I have a problem haha.
