The larger tablet measures 14.6 inches, while the smaller model has a 12.4-inch-class design; both run Android 17 at launch. Samsung has set October 7 as the start of sales in selected markets. Spanish pricing and a local sales date remain unconfirmed.
The Galaxy Tab S12 Ultra measures 208.5 × 326.3 × 5.1 mm. It weighs 692 grams in its WiFi version and 695 grams with 5G. The S12+ measures 187.8 × 289.5 × 5.3 mm and weighs 553 or 555 grams. That 140-gram difference makes the Plus easier to handle during long sessions.
In the United States, the Galaxy Tab S12+ starts at $1,199.99, while the Galaxy Tab S12 Ultra starts at $1,399.99, Samsung says.
Both tablets use Dynamic AMOLED 2X panels with a 120 Hz refresh rate. The Ultra has a resolution of 2,960 × 1,848 pixels; the S12+ offers 2,800 × 1,752 pixels. Samsung claims peak brightness of 1,600 nits. Its outdoor high-brightness mode reaches 1,000 nits, while Vision Booster adjusts the image to ambient light.
Four speakers deliver four-channel spatial audio. Both tablets have IP68 protection, based on laboratory tests in fresh water at up to 1.5 metres for 30 minutes. Their specifications differ in other ways, too.
The Ultra has a 13 MP basic rear camera and an 8 MP ultra-wide camera. The S12+ keeps the 13 MP basic camera but has no second rear sensor. Both models include a 12 MP front ultra-wide camera, along with an in-display fingerprint reader. The Ultra supports WiFi 7, while the Plus uses WiFi 6E. Both versions offer Bluetooth 6.0 and 5G variants, depending on the market.
The new US prices exceed the previous generation's launch prices. Independent coverage from Neowin and 9to5Google calls the increase impressive; Samsung says local prices and availability may vary by market.
Both tablets use the MediaTek Dimensity 9500 and a three-dimensional vapour chamber to dissipate heat. Comparing the new models with the S11 Ultra, Samsung reports gains of up to 61% in NPU performance. It also reports CPU performance gains of up to 19% and GPU performance gains of up to 17%. These figures come from Samsung, not independent testing. The company's Global Newsroom announcement links the processor and cooling system to a broader performance upgrade.
The Ultra comes with 12 GB of RAM and either 256 or 512 GB of storage. A higher configuration pairs 16 GB of RAM with 1 TB of storage. The Plus offers 12 GB of RAM with 256 or 512 GB. Both tablets accept microSD cards of up to 2 TB.
The Ultra has an 11,600 mAh battery; the Plus uses a 10,600 mAh battery. Samsung estimates up to 23 hours of video playback on the Ultra and 21 hours on the Plus, based on a local 720p file under laboratory conditions. Both support 45 W wired charging. The required adapter is sold separately.
One UI 9 and Android 17 support Multi Window with up to three sections. Note Assist can summarise notes in Samsung Notes when the user is signed in and the note contains at least 200 characters. Galaxy AI features and other productivity tools are also available.
Photoshop will come preinstalled in a selected-apps folder. Available applications include Notability and Goodnotes, as well as LumaFusion. Promotions and trial periods may vary by country; some announced offers apply specifically to Canada.
The S Pen is included. This version lacks Bluetooth support, so it does not offer the remote functions some buyers may expect. The Pro Keyboard and Book Cover Keyboard Slim are optional accessories. The Pro Keyboard has a configurable basic for AI assistants, which requires a network connection.
The Galaxy Tab S12 range combines large AMOLED screens with thin bodies, and users can expand the storage. On paper, the Ultra has stronger specifications, including WiFi 7 and a second rear camera. It also offers a 1 TB configuration. The S12+ drops those extras and weighs less.
Samsung's regional pages and local reports indicate that memory options and prices can vary across Asia and Europe. The company has not confirmed Spanish pricing or availability.
