Slim, Flexible TPU Protection Built for the Samsung Galaxy Note 9
The Galaxy Note 9 is a precision instrument—its S Pen, large 6.4" display, and dual cameras deserve a case that protects without bulk. The Red Pepper Cases Galaxy Note 9 Soft TPU Case wraps your device in resilient thermoplastic polyurethane that absorbs impact, resists scratches, and stays clear for the life of your phone. At just 1.5 mm thin, you'll barely know it's there. Browse our full range of Galaxy Note 9 Cases to find every style and protection level we carry.

Installation Guide
- Prepare: Power off your Galaxy Note 9 and remove any existing case.
- Align: Hold the TPU case open-face up. Align the bottom of the phone—USB-C port first—with the bottom opening of the case.
- Seat the corners: Push both bottom corners into the case frame until they sit flush.
- Roll on: Apply gentle pressure from the bottom up, pressing the side rails down along both edges.
- Snap the top: Press the top two corners down firmly until fully seated.
- Verify: Check all four corners are flush, confirm the S Pen slot is accessible, and test all buttons through the case.
Total install time: approximately 15 seconds.
Troubleshooting
- Case feels loose at corners? TPU stretches slightly in heat. Remove and re-snap at room temperature (20–25°C / 68–77°F).
- Wireless charging stops mid-charge? Ensure the case is fully seated—any raised corner can misalign the charging coil.
- Yellowing after several months? Clear TPU can develop a slight tint from UV exposure. This is cosmetic only and does not affect protection. Switch to Transparent Black for UV-invisible wear.
- S Pen sticking? A small amount of 70% isopropyl alcohol on a cotton swab cleans the S Pen channel in 30 seconds.
- Buttons feel stiff? Button covers loosen naturally after 48–72 hours of use as the TPU conforms to your phone.
Frequently Asked Questions
Q: Will this fit the Samsung Galaxy Note 9 (SM-N960)?
A: Yes. Designed exclusively for the Galaxy Note 9 (SM-N960U, SM-N960F). It will not fit Note 8 or Note 10.
Q: Is this compatible with a Galaxy Note 9 screen protector?
A: Yes. The 0.5 mm raised lip works with standard 0.33 mm tempered glass screen protectors. Full-edge glass protectors may lift slightly at the corners.
Q: Does it support Samsung DeX?
A: Yes. The USB-C cutout is 12 × 7 mm—wide enough for all DeX pad and DeX station cables without removing the case.
Q: How do I clean the case?
A: Wipe with a damp microfiber cloth or 70% isopropyl alcohol. Avoid acetone, bleach, or abrasive pads—these degrade TPU clarity.
Q: Will the clear case turn yellow?
A: The clear variant includes a UV-stable additive that slows yellowing for 12+ months under typical indoor use. Prolonged direct sun exposure may accelerate tinting over 18–24 months.
Q: Can I use magnetic car mounts?
A: Yes, with an adhesive metal plate (not included) placed between the phone and case. The TPU itself contains no metal.
Q: What is the drop-protection rating?
A: Designed for everyday protection from drops up to approximately 1.5 m on flat surfaces. Not rated MIL-STD-810G. For military-grade protection, see our aluminum bumper options.
Q: How thick is the case?
A: 1.2 mm at sides and back; 1.5 mm at the four reinforced corner zones.
