LifeProof makes replacement parts such as screen protectors for iPhone 5 cases and o-rings, jack covers and keepers for iPhone 4 cases, as of April 2015. The company also sells replacement iPhone and Samsung headphone adapters and scratch protectors for Galaxy S3 cases.
LifeProof cases and replacement parts keep dirt, snow, sand and water out of the mobile devices for which they are made, such as Samsung, Motorola and Apple products. LifeProof conducts an individual water test on each case to ensure it does not leak, and it discards all leaking cases. The company constructs its products to surpass strict military standards, offering superior damage protection if a consumer drops his device.
