The Galaxy S23 Plus (SM-S916) is 157.8 x 76.2 x 7.6 mm, 196 g, with a 6.6-inch flat display, a 4,700 mAh battery and 45 W wired charging. It also introduced the design that defines this generation: no camera island at all, just three lens rings sitting directly on a flat back.
That last detail drives most of what follows. The lenses on an S23 Plus have no housing protecting them, and Samsung committed to four generations of OS updates on this series — so these phones are worth keeping in good condition.
Best all-rounder: kickstand with drop protection
At 196 g and nearly 158 mm tall, the S23 Plus is a two-handed phone for most people. A built-in kickstand gives your fingers a purchase point, which prevents drops rather than surviving them.
When a listing cites military-grade drop protection it is referencing MIL-STD-810 test methods, which specify a drop sequence onto plywood over concrete. It is a meaningful standard but it is not a warranty — treat it as evidence of design intent rather than a guarantee.
Best for carrying cards: leather multi-card holster wallet
If you would rather not carry a wallet at all, a multi-slot leather folio does the job. On a phone this size the extra bulk is proportionally less noticeable than it would be on a compact model.
Practical warning that applies to every wallet case: cards stacked over the phone's back will block Qi wireless charging, and a magnetic clasp sitting near a contactless card can, over time, be a nuisance for the card. Keep the clasp away from the card pocket.
Best for exposed lenses: slide camera cover
Because the S23 Plus lenses sit unhoused on a flat back, abrasion is the real threat — keys, grit and sand working directly against the lens coating. A sliding shutter removes that exposure entirely and doubles as a hardware privacy cover.
You will occasionally take a photo of the inside of the shutter. Everyone does. It is a fair price for a lens that stays clear.
Best for outdoors and worksites: camouflage
Camo patterns are not only cosmetic on a work phone — a patterned back is far easier to spot on a leaf-covered forest floor or a cluttered truck bed than a black slab, and it hides scuffs that would show immediately on a plain finish.
Best if you want case and glass together
A case with an integrated tempered glass front removes the alignment problem and guarantees the two components clear each other. On a flat-screen phone like the S23 Plus this format works well.
Whatever you fit over the display, the S23 Plus uses an ultrasonic in-display fingerprint reader. Choose a protector rated for it and re-register your fingerprint after applying.

Frequently asked questions
Will an S22 Plus case fit an S23 Plus? No. The dimensions are close (157.4 vs 157.8 mm) but the S22 Plus has a raised camera island and the S23 Plus does not. The cutout is wrong.
Will an S24 Plus case fit? No. The S24 Plus is 158.5 x 75.9 x 7.7 mm with different corner geometry.
Does the S23 Plus support magnetic accessories? Only through a case with magnets built in. There are no magnets in the phone.
How long will this phone be supported? Samsung committed to four generations of Android upgrades and five years of security updates for the S23 series, so it has meaningful life left.
Which model number is it? SM-S916. Check Settings > About phone > Model number, or ask via the Contact page or 978-797-0223.
The bottom line
The S23 Plus is big, heavy and has unprotected lenses. A kickstand for grip and either a slide cover or a lens ring for the cameras covers the two genuine weak points. Everything else is preference.
