Quad Lock® QMC-GS23U MAG Case for Galaxy S23 Ultra, Twist Lock and MAG Mounting

The problem it fixes

A Galaxy S23 Ultra sliding round the console or held up by a cheap vent clip is no good when you need the map. This case gives it a proper Quad Lock fitting, so the phone goes on the mount in a second and stays put until you take it off.

Fitting it

Questions we get asked

Will the QMC-GS23U fit the Galaxy S23?

No. This MAG case is shaped for the Galaxy S23 Ultra only. The Galaxy S23 has a different body and camera layout, so it needs QMC-GS23 instead.

How do I check my phone is a Galaxy S23 Ultra before ordering the QMC-GS23U?

Go to Settings, About phone, and read the model name at the top. It has a 6.8 inch screen. It came out in 2023. If it shows Galaxy S23 Ultra, the QMC-GS23U is the right MAG case.

Can I still get the S Pen out with the QMC-GS23U on my Galaxy S23 Ultra?

Yes. Quad Lock cuts a notch into the QMC-GS23U so the S Pen slides in and out of your Galaxy S23 Ultra with the case fitted.

My Galaxy S23 Ultra has no MagSafe style magnets. Will MAG mounts still hold it?

Yes. The QMC-GS23U has its own magnets in the MAG ring on the back, so a MAG mount holds your Galaxy S23 Ultra through the case, not through the phone. It still twist locks onto every standard Quad Lock mount too.

Is there a screen protector that fits under the QMC-GS23U?

Yes. The Quad Lock ANX-GSP-GS23U TPU film protector suits the Galaxy S23 Ultra and is cut to sit under the QMC-GS23U.

How heavy is the QMC-GS23U?

Quad Lock lists the QMC-GS23U at about 83g, so it adds very little to your Galaxy S23 Ultra.
