Galaxy S23 Ultra

Galaxy S23 Ultra: what affects the choice of accessories

The Galaxy S23 Ultra has a 6.8-inch Dynamic AMOLED 2X screen with a 120 Hz refresh rate. The panel is gently curved at the sides: less than on the Galaxy S22 Ultra, but enough that ordinary flat glass does not stick right up to the edge. The body measures 163.4 × 78.1 × 8.9 mm and weighs 234 g, the front and back are covered with Gorilla Glass Victus 2, and the frame is aluminium. The phone is rated IP68 and supports 45 W wired charging, 15 W Qi wireless charging and 4.5 W reverse charging. On the back there are four separate lenses arranged vertically, and in the bottom edge sits the S Pen slot.

Cases for the Galaxy S23 Ultra

Every case for this model needs a cut-out at the S Pen slot so that the stylus can be pulled out without removing the cover. The range includes:

• rugged and reinforced cases: with thicker corners and a raised lip over the screen, from brands such as Urban Armor Gear and Supcase,
• kickstand cases: with a fold-out stand for watching videos in landscape,
• leather and faux leather cases: including licensed Guess, Karl Lagerfeld and BMW designs,
• flip wallet cases: with a card slot,
• slim clear and matte cases: from Dux Ducis, 3MK, Ringke and others.

Tempered glass and screen film for the Galaxy S23 Ultra

Because the sides of the screen are curved, protection comes in several forms:

Tempered glass

Glass with UV-cured adhesive fills the gap at the curve and bonds to the entire screen. Edge-adhesive glass is often easier to fit, but a bubble along the edge is more likely. Some kits include an applicator that helps with centring.

Protective films

Hydrogel and TPU films conform to the curve of the screen and do not lift at the edges of a case. Matte films and versions with an antibacterial additive are also available. Whatever screen protection you use, it is worth registering your fingerprint again, as the ultrasonic sensor reads through an extra layer.

Camera protectors

The four protruding lenses can be covered with camera glass, either as individual rings for each lens or as a single overlay. Textured films are also available for the back.

Charging and extras for the Galaxy S23 Ultra

The phone supports Qi wireless charging, so it works with most wireless chargers. If you want to snap it easily onto magnetic mounts, choose a case with a built-in magnetic ring, as the phone itself has no magnets in its body. Thick rugged cases can weaken wireless charging, so if you use a wireless charger every day, check whether the case maker mentions it.

Accessories for other Galaxy S models

The Galaxy S23 Ultra has a different body shape and camera layout from both its predecessor and its successor, so cases are not interchangeable. You will find accessories for the other models in the Galaxy S22 Ultra, Galaxy S24 Ultra and Galaxy S23 categories, and the full list of the series in the Galaxy S accessories category.

Frequently asked questions

Does a Galaxy S22 Ultra case fit the Galaxy S23 Ultra?

No. The models differ in dimensions, edge profile and camera layout, so the case has to be chosen specifically for the Galaxy S23 Ultra.

Does the S Pen work through tempered glass?

Yes, thin glass and films do not get in the way of writing with the S Pen. Thicker protection may slightly change how the tip feels on the screen, but it does not affect stylus detection.
