Samsung Galaxy S21 Ultra Case FAQs
What kinds of Samsung Galaxy S21 Ultra cases does DECO CASES offer?
The Samsung Galaxy S21 Ultra comes in two case types: Tough and Flexi. Tough Cases have a hard polycarbonate shell over a flexible TPU liner for dual-layer protection from everyday drops and bumps, printed edge to edge in a glossy finish. Flexi Cases are slim and lightweight, made from flexible, shock-absorbing TPU with a matte finish.
Which case designs can I get for my Galaxy S21 Ultra?
Every DECO design comes for the Samsung Galaxy S21 Ultra: 160+ designs in marble, floral, animal skins, western tooled leather looks, geometric, plaid, hearts, polka dots, watercolor, swirls, stripes, pastels, industrial metal looks and patriotic America designs, plus the DECO Signature collection of printed gold, gemstone and diamond looks. During the holidays, the Christmas collection comes as Tough cases.
Do Galaxy S21 Ultra cases from DECO work with wireless charging?
Tough and Flexi cases work with wireless charging on phones that support it, so there is no need to take your case off.
How do I know which Samsung Galaxy model I have?
On your Galaxy, go to Settings > About phone to see the model name. Then choose that model from the Phone Model menu, since every DECO case is made for one specific phone model.
Are the gold, gemstone and marble designs real?
No. Every DECO design is printed on the case, so nothing is attached and the case stays slim. DECO Signature gold, gemstone and diamond designs use a premium print process with the look to simulate texture and sparkle.
Can I get a matching AirPods case, phone grip or power bank?
Yes. DECO designs also come as an AirPod Case and a click-on Phone Grip & Stand, so you can match your case.
How much is shipping and how fast will my Galaxy S21 Ultra case arrive?
Standard Shipping is a flat $4.95 on orders under $60 and free on orders of $60 or more. Orders ship in 2-3 business days, and standard delivery takes 5-7 days after your order ships. We ship within the USA.
