5. Troubleshooting
If you encounter any issues with your OtterBox Defender Series case, consider the following common solutions:
- Difficulty Installing/Removing Tablet:
Ensure you are separating all case components as described in the "Setup and Installation" section. Do not force the tablet into the case; ensure it is aligned correctly before attempting to close the inner shell or apply the slipcover.
- Port Covers Not Sealing:
Check for any debris (dust, lint) obstructing the seal of the port covers. Clean the covers and the port openings on your tablet. Ensure the outer slipcover is correctly seated around the inner shell, as misalignment can affect port cover function.
