Does iphone 5 cases fit the 5s

The phones are the same dimensions, so they will fit. Depending on the case, you'll need to verify if the new dual flash will work

There may be isues with the fingerprint scanner.

Nope the case won't work. The camera and flash don't line up the same as the 5

It works great. I put my iPhone 5 version Lifeproof fre case on my new 5S and everything lines up. The camera hole lines up and the flash hole is just barely big enough for the new dual flash. I took a flashlight to the front of the 5S and all the sensors on the front of the device by the front camera are in the same place as the 5. I took some test pictures and they are fine, no vignetting. No fingerprint sensor functionality but I assume that is what Lifeproof is working on with the 5S case.

I got the nüüd and it don't line up whatsoever. The objective is larger on the 5s than the 5

does the lifproof case work on it includinf fingerprint scann??

because i dont want to waste my mony on a case that im not sure even works
