Samsung Galaxy S26 Ultra Review (2026): Worth Upgrading?

This Samsung Galaxy S26 Ultra (512GB, Black, SM-S948UZKEXAA) review looks at Samsung's Galaxy S26 Ultra and asks the question most buyers have: is it a big enough step to justify the upgrade? It pairs a 6.9-inch display with a built-in S Pen, a four-camera array led by a 200 MP main sensor, and a promise of up to 7 major OS updates. It is aimed at power users coming from older phones who want a do-everything handset.

This review is based on Samsung's specifications and on what independent expert reviews report. It is not based on our own hands-on testing.

Design and build

The S26 Ultra measures 163.6 x 78.1 x 7.9 mm and weighs 214 g. Samsung also describes it as thinner and lighter than previous Ultra models, so the company has clearly tried to slim the Ultra down rather than just make it bigger.

It carries an IP68 rating for water and dust resistance. The S Pen is built in rather than a separate accessory, a defining trait of the Ultra line. One practical point is storage: the 512GB configuration has no card slot, so what you choose at purchase is what you have. With 12 GB of RAM alongside it, this is a well-equipped configuration for people who keep a lot of photos, video and apps on the device.

The display and the Privacy Display

The screen is a 6.9 in Dynamic LTPO AMOLED 2X panel at 1440 x 3120 pixels, with a 1-120Hz adaptive refresh rate. Peak brightness is rated at 2600 nits. In everyday terms, that means a large, sharp screen with a refresh rate that can scale to the content on it. Reviewers consistently praise the display.

The headline feature is the built-in Privacy Display, which hides screen content from people looking from the side. If you read email, banking apps or messages on trains, in queues or in open-plan offices, this is a practical addition for anyone who reads sensitive content in public. The trade-off, which reviewers raise, is that the Privacy Display slightly reduces image quality. It is worth keeping in mind if you care about the very best picture.

Performance and software

Inside is the Snapdragon 8 Elite Gen 5 for Galaxy, built on a 3 nm process, with 12 GB of RAM. Samsung positions it for fast gaming and multitasking, and reviewers say it delivers fast performance and good sustained gaming. For anyone running several apps at once, editing photos on the phone or playing demanding games, the hardware is aimed squarely at that kind of use.

The phone ships with Android 16 and One UI 8.5, and Samsung promises up to 7 major OS updates. That long support window is one of the strongest practical arguments for the S26 Ultra. If you tend to keep a phone for many years, you are buying into a long runway of new Android versions rather than a device that stops moving forward early.

Cameras

The rear setup has four cameras:

• a 200 MP wide camera with an f/1.4 aperture, which Samsung says helps low-light shots
• a 50 MP f/1.9 ultra-wide
• a 50 MP f/2.9 5x telephoto
• a 10 MP f/2.4 3x telephoto

The front camera is 12 MP at f/2.2.

Having both a 3x and a 5x telephoto alongside the main and ultra-wide cameras gives you a range of focal lengths without relying solely on digital cropping. Reviewers describe the system as versatile, with a 200 MP main camera and strong zoom. That matches the spec sheet.

There is a caveat. A common criticism is that the camera upgrade is small compared with the S25 Ultra, and some reviewers say the telephoto camera trails some rivals. If photography is your single biggest priority and you already own a recent Ultra, the camera alone is unlikely to make the case for upgrading. If you are coming from an older phone, the S26 Ultra is the better-suited upgrade, since the modest gains matter mainly to S25 Ultra owners.

Battery and charging

The battery is 5000 mAh. Wired charging runs at 60W, and Samsung says it reaches up to 75% in around 30 mins. Wireless charging is supported at 25W. For a phone of this size, those charging speeds make topping up during the day quick and convenient.

Two criticisms are worth noting. Reviewers say battery gains over the S25 Ultra are small, and that battery life trails some rivals. There is also no magnetic, MagSafe-style wireless charging, so if you rely on magnetic mounts, car holders or snap-on chargers, check that your accessories will work. Battery life trailing some rivals is a fair reason to keep expectations realistic.

Connectivity

The connectivity list is thorough: 5G, Wi-Fi 7, Bluetooth 6.0, NFC, USB Type-C 3.2, and both nano SIM and eSIM. That gives you the latest wireless standards and flexibility for travel or running two lines. Nothing here is a weak point for a premium phone, and it should keep the phone current as networks and accessories evolve.

What experts like and what they criticise

The S26 Ultra averages 8.9/10 across 4 expert reviews. TechRadar scores it 4.75/5, GSMArena 4.5/5, Amateur Photographer 4.5/5 and PhoneArena 8.1/10.

The praise falls into a few areas:

• the bright, large AMOLED display with its 1-120Hz refresh and 2600 nits peak
• the Privacy Display
• strong performance, including sustained gaming
• the versatile four-camera setup
• the charging options and long software support

The criticism is more about restraint than failure:

• camera and battery upgrades are small compared with the S25 Ultra
• there is no magnetic wireless charging
• the Privacy Display slightly reduces image quality
• battery life and the telephoto camera trail some rivals

This is a very strong phone that does not rewrite the formula for anyone already on the previous generation.

Who should buy it, and who should skip it

Buy it if you are a power user upgrading from an older phone and want a big, bright screen, a built-in S Pen, a flexible camera system and years of software updates. It also suits you if you often use your phone in public and value the Privacy Display, or if you want fast charging and the latest connectivity standards.

Skip it if you already own an S25 Ultra. The camera and battery gains are modest, so the upgrade is hard to justify. You may also want to look elsewhere if you rely on magnetic wireless charging accessories, if you want the longest possible battery life, or if you want a larger storage ceiling than a phone with no card slot can offer.

How it fits in the wider phone market

The Ultra pairs a 6.9-inch display, four rear cameras and a built-in S Pen. It is for people who would rather have every feature than a simpler, smaller handset.

Verdict

The Samsung Galaxy S26 Ultra (512GB, Black) is a polished, feature-rich flagship that earns its high expert scores through its display, performance, cameras, charging and long update promise. It is best for upgraders from older phones. Those on the S25 Ultra have little reason to move, because the improvements are incremental. For everyone else who wants an S Pen and a full-featured flagship, it is an easy one to shortlist.
