5. Water Test (First Time Use)

Before placing your iPhone 16 into the case for the first time, it is highly recommended to perform a water test to ensure the case's integrity. Do not install your device during this test.

  1. Case Assembly: Pick up the front case and line up the back case with it, ensuring all edges are firmly pressed around the entire perimeter.
  2. Submersion: Place the empty case in water and weigh it down with something non-heavy (e.g., a small stone) for at least 30 minutes.
  3. Inspection: Completely dry the outside of the case. Open the case and inspect the interior for any signs of water ingress.
  4. Result: If no visible water drops appear inside, the case has passed the test and is ready for use. If water is present, re-check the seals and repeat the test. If water still enters, contact customer support.
