Samsung Galaxy Tab S10 Ultra Review 2026

Why you should trust this review

I bought this tablet and used it for seven months across productivity and travel. Samsung had no involvement and no input here. A huge, expensive tablet only proves itself over time: whether the enormous screen is a joy or an awkwardness, whether DeX holds up as a daily work tool, and whether the battery survives heavy use are all questions a launch review cannot answer. Seven months of real use can.

I leaned on the Tab S10 Ultra as a productivity machine and a travel companion, the two jobs a 14.6-inch tablet is really for, and compared it against the iPad and Surface devices buyers cross-shop. Here is the honest verdict.

How we evaluated

I used the Tab S10 Ultra as a primary work and media device for seven months. I ran DeX with a keyboard for extended writing and editing sessions to test the laptop-replacement claim. I pushed the Dimensity chip through demanding apps and long gaming sessions to find its thermal and performance limits. I used the included S Pen daily for notes and markup, took the tablet through travel and varied lighting to judge the AMOLED panel, and tracked battery across real mixed-use days rather than a single benchmark run.

Display

The 14.6-inch Dynamic AMOLED 2X is the biggest tablet screen genuinely worth owning. It is enormous, sharp, and the 120Hz refresh keeps everything fluid, and for media, split-screen multitasking, and creative work the sheer real estate is transformative. Watching film on it is closer to a portable monitor than a tablet. The one persistent oddity is the front-camera notch cut into the display. In portrait it disappears, but in landscape, which is how you hold a tablet this size most of the time, it sits there looking strange. It does not break anything functionally, but on a device this premium it is a design choice I never fully made peace with. That aside, the panel is the best reason to buy this tablet.

Performance and the chip trade-off

The Dimensity 9300+ is a small step down from the Snapdragon you would find in a phone flagship, but in practice it handles everything outside heavy gaming without complaint. Productivity, multitasking, media, and most apps run smoothly, and the 12GB of RAM keeps DeX and multiple windows responsive. The honest limit is sustained heavy gaming, where the chip runs warmer than a Snapdragon and you feel the heat on long sessions. For a tablet bought primarily for productivity, that is a reasonable trade, but if gaming is your main use, a cooler-running device makes more sense. For everything I actually do on a large tablet, the performance never got in the way.

S Pen and DeX

The S Pen ships in the box, needs no battery, and charges magnetically on the back, and its latency is low enough that writing feels immediate. For notes and markup on a screen this large, it is excellent, and Samsung Notes remains the best handwriting experience on any tablet. DeX is the feature that makes the Ultra a credible laptop alternative. With the keyboard attached, it becomes a windowed Android desktop with real window management, and I genuinely used it instead of a laptop for travel work weeks. The catch is the Book Cover Keyboard, which is sold separately and is expensive, so the full laptop-replacement experience carries an additional cost beyond the tablet itself.

Battery, build, and longevity

The 11,200 mAh battery is large, and across seven months it comfortably handled full mixed-use days, with 45W charging topping it up at a reasonable pace. Build quality is excellent, with a premium metal chassis and an IP68 rating that meant I stopped worrying about rain and pool-deck use, a rare and genuinely useful feature on a tablet. The microSD slot supporting up to 1.5TB is a practical bonus for anyone storing large media libraries. Samsung’s seven-year update commitment also means this tablet should stay current for far longer than most, which matters more on a device you are paying a premium for and intend to keep.

Who should buy the Galaxy Tab S10 Ultra?

Buy it if you want the largest premium Android tablet, you will use DeX as a genuine laptop substitute, and you value an included stylus, a massive AMOLED panel, IP68 durability, and long software support. For Android-first productivity users who want maximum screen, this is the one.

Skip it if heavy gaming is your priority, you want Apple silicon performance, or you do not need a screen this large and would rather not pay for it. The iPad Pro suits demanding creators, and the Surface Pro fits anyone who needs Windows compatibility.

The verdict

Seven months with the Tab S10 Ultra confirmed it is the only Android tablet that meaningfully challenges the iPad Pro. The 14.6-inch AMOLED is the best big tablet screen you can buy, DeX turns it into a real laptop replacement, the included S Pen is excellent, and IP68 plus seven years of updates make it a tablet built to last. The honest caveats are the persistent landscape notch, a chip that runs warm under heavy gaming, and an expensive keyboard sold separately. None of those undercut its core strength as a productivity-first powerhouse. If you want the most capable large Android tablet and you live in Samsung’s ecosystem, the Tab S10 Ultra earns the recommendation. If you need raw gaming performance or Apple’s app library, look elsewhere.
