All features still work great. It has never been outside of the Lifeproof Nuud case. The Nuud Case is no longer waterproof though as I lost the headphone jack cover.
You might be able to get a spare from Lifeproof. Camera and sensors all work great. Battery still holds a great charge. Must pay within 48 hours.
