Frequently asked questions
Is the Phantom Black colour the same as my phone?
It is made to match the Phantom Black colour option of the Galaxy S21 Ultra. Check which colour your phone came in before ordering.
Will this back cover fit my Galaxy S21 Plus?
No. This cover fits the Galaxy S21 Ultra (SM-G998B) only. Each Galaxy S model has a different size and camera layout.
Will my phone still be water resistant?
Once the back has been removed the factory water resistance cannot be relied on. A careful fit with fresh adhesive helps, but keep the phone away from water.
How fast will it arrive?
Orders placed before 4pm, Monday to Friday, are dispatched the same day from Manchester.
