You probably won't find many options for that. I just bought a Vivo XL (which came with a clear TPU case), and I can't hardly find anything for it either. Now, I did find out that the Vivo XL is actually just a rebranded Gionee Elife S Plus, so I found more options under that name. If you can find out which phone the Vivo 5 is cloned after, maybe you'll have more luck. BTW...what network are you on? I was looking to get one of those, but I think it's missing a few bands that I would need for good AT&T LTE service.
