Our take on the Quad Lock Mag Phone Case for Samsung Galaxy S24 Ultra

The Quad Lock Mag Case is a hard-shell case for the Galaxy S24 Ultra built around two things: Quad Lock's twist-and-lock mount system and a ring of magnets for MagSafe-style accessories. It is thicker and heavier than a plain slim case, but it locks the phone firmly to bike, car and tripod mounts and holds magnetic chargers and wallets. Reviewers rate the mount security highly and note the case adds bulk and needs a separate Mag head or adapter for the classic twist mount. It suits riders, drivers and anyone who wants one case that works with mounts and magnets; buyers who want the thinnest possible case should look elsewhere.

Questions and answers

Does it fit the Galaxy S24 Ultra only?
It is listed to fit both the Galaxy S24 Ultra and the Galaxy S25 Ultra. Check the camera cutout and button positions on your model before buying.
Does it work with MagSafe chargers?
Yes. The built-in magnet ring aligns with MagSafe-style chargers, wallets and mounts, though charging speed depends on the charger.
Do I need an extra part for Quad Lock mounts?
For the classic twist mounts you need the Quad Lock Mag head or adapter. The case's own magnets are for magnetic accessories.
Does the S Pen still work with the case on?
Yes. The case leaves the S Pen slot accessible and does not interfere with stylus use.
Is it good for cycling?
Yes. The twist lock is the main reason to buy it, and owners report a firm hold on bike mounts even on rough roads.
How much protection does it offer?
It is a hard plastic shell with raised edges, good for everyday drops and scratches. It is not a rugged waterproof case.
