THE SHORT VERSION
- The S12 lineup has a 12.6-inch Plus and a 14.6-inch Ultra; Samsung's U.S. launch announcement says both include the S Pen.S12 系列包括 12.6 英寸 Plus 和 14.6 英寸 Ultra；三星美国发布资料称两款都附赠 S Pen。
- Samsung lists the Pro Keyboard and Book Cover Keyboard Slim as separate purchases, and Adobe Photoshop's Galaxy Store exclusivity starts October 7 for at least six months.三星将 Pro Keyboard 与 Book Cover Keyboard Slim 列为另售配件，Adobe Photoshop 在 Galaxy Store 的独家期从 10 月 7 日起至少持续六个月。
- The U.S. starting prices are reported as $1,199.99 and $1,399.99; Korea publishes separate price ranges by memory and storage configuration.Android Authority 报道美国起售价分别为 1,199.99 美元和 1,399.99 美元；韩国则按内存和存储容量列出不同价格范围。
The S12 family starts with Plus and UltraS12 系列从 Plus 和 Ultra 起步
Samsung's Galaxy Tab S12 launch consists of two models: the 12.6-inch Galaxy Tab S12+ and the 14.6-inch S12 Ultra. There is no smaller standard S12 in the U.S. release list. Android Authority reports starting prices of $1,199.99 for the Plus and $1,399.99 for the Ultra, with both available from October 7. The 200-dollar starting-price gap buys a larger display and the Ultra's higher tier, so the first question is whether that extra screen will be used often enough to justify the difference.三星 Galaxy Tab S12 系列有两款：12.6 英寸 Galaxy Tab S12+ 和 14.6 英寸 S12 Ultra。美国发布清单里没有一款更小的标准 S12。Android Authority 报道，Plus 起售价为 1,199.99 美元，Ultra 起售价为 1,399.99 美元，两款都从 10 月 7 日开始供应。200 美元的起价差异主要买到更大的屏幕和 Ultra 档配置，因此首先要问的是，大屏幕是否足够常用，值得为它多付这笔钱。
The Korean launch announcement shows why one country's price cannot stand in for another. It lists the Ultra between 1,899,700 and 3,018,400 won and the Plus between 1,549,900 and 2,069,100 won, depending on memory and storage. A buyer comparing across markets should first match the same model and capacity, then add local tax and any launch promotion. The Korean figures are not directly comparable with the U.S. starting prices without knowing which configuration is being compared.韩国上市公告能说明为什么一个国家的售价不能代表另一个国家。公告列出 S12 Ultra 的价格范围为 1,899,700 至 3,018,400 韩元，S12+ 为 1,549,900 至 2,069,100 韩元，具体取决于内存和存储。跨地区比较时，应先找到相同型号和容量，再计算当地税费与促销。若不知道对照的是哪种容量，韩国价格不能直接与美国起售价相比。
The display difference changes how each tablet travels屏幕尺寸会影响平板怎么随身带
Samsung lists the S12 Ultra at 14.6 inches and 5.1 millimeters thick. Samsung UK's model-specific S12+ specifications define its display as 12.6 inches (320.4 mm) full rectangle and 12.5 inches (317.8 mm) at the rounded corners. Samsung Korea's October 1 product release also gives 12.6 inches (320.4 mm), matching the U.S. launch release. An earlier read of the October 6 Korean retail notice recorded 12.4 inches, but a direct reread today no longer shows a screen-size value. The model specification and two product releases point to 12.6 inches nominal; the earlier notice is a source-text conflict, not evidence of a separate Korean panel. The current Korean notice lists the Plus at 5.3 millimeters thick and 553 grams. Both are large tablets, but the Plus is easier to fit on a small table, hold beside a textbook, or carry with a compact sleeve. The Ultra gives more room for two or three windows, a timeline, or a sheet of music. It also occupies more of a lap and desk.三星列出的 S12 Ultra 厚度为 5.1 毫米、屏幕为 14.6 英寸。三星英国针对 S12+ 的机型规格将屏幕列为全矩形 12.6 英寸（320.4 毫米），按圆角计算为 12.5 英寸（317.8 毫米）。三星韩国 10 月 1 日的产品公告也列出 12.6 英寸（320.4 毫米），与美国上市公告一致。此前对 10 月 6 日韩国零售上市公告的直读记录了 12.4 英寸，但今天重新打开时正文已不再列出屏幕尺寸。机型规格和两份产品公告均支持标称 12.6 英寸；早前公告数字属于来源文本冲突，不足以证明韩国版采用不同屏幕。韩国当前上市公告列出 Plus 厚 5.3 毫米、重 553 克。两款平板都很大，不过 Plus 更容易放在小桌面上，带到课堂里和教材一起使用，或装进紧凑型平板套。Ultra 可以为多窗口、视频时间线或乐谱提供更多空间，也会占据更多膝上和桌面面积。
The screen size is not the only difference. Samsung describes both displays as Dynamic AMOLED 2X, with up to a 120Hz refresh rate and 1,600-nit peak brightness in its product materials. These are manufacturer specifications. They do not tell us how a specific document, video, or app will look under a shop's lighting, so a store display is useful for checking glare, font size, and split-screen comfort. Buyers should test the apps they plan to use rather than rely on a diagonal measurement alone.除了尺寸，屏幕规格也有差别。三星的产品资料将两款屏幕都描述为 Dynamic AMOLED 2X，并列出最高 120Hz 刷新率和 1,600 尼特峰值亮度。这些是厂商规格，并不能说明具体文件、视频或应用在店内灯光下看起来怎样。用店内展示机检查反光、字体大小和分屏舒适度会更直接。与其只看对角线数字，不如试试自己实际会使用的应用。
The S Pen is in the box; keyboard covers are not盒内有 S Pen，键盘盖需要另买
Samsung says both S12 models ship with an S Pen. That lowers the cost of trying handwriting, markup, sketching, or selecting small screen elements compared with a tablet that sells its pen separately. The S Pen does not automatically turn either tablet into a laptop. People who type for long stretches still need a keyboard and trackpad setup, and Samsung lists its Pro Keyboard and Book Cover Keyboard Slim as separate purchases.三星表示两款 S12 都随盒附送 S Pen。与单独出售触控笔的平板相比，这降低了尝试手写、批注、草图或点选小屏幕元素的门槛。但 S Pen 并不会自动让平板变成笔记本。经常长时间打字的人仍需要键盘和触控板方案，而三星把 Pro Keyboard 与 Book Cover Keyboard Slim 列为另售配件。
Keyboard prices and layouts vary by country, language, and device model, according to Samsung's footnote. The Pro Keyboard includes a Galaxy AI Key, but Samsung says that key can be assigned only to select apps and needs a network connection for Bixby, Gemini, or Perplexity. The Book Cover Keyboard Slim is another option with adjustable viewing angles. Add the exact local accessory price to the tablet before treating the Ultra as a complete workstation purchase.根据三星脚注，键盘价格和布局会因国家、语言和型号而异。Pro Keyboard 带 Galaxy AI 键，但三星说明它只能分配给部分应用；使用 Bixby、Gemini 或 Perplexity 还需要网络连接。Book Cover Keyboard Slim 是另一个可调观看角度的选项。购买 Ultra 时应把当地键盘价格计入整套设备成本，不能把平板价格当作完整工作站费用。
Photoshop has an exclusive Galaxy Store windowPhotoshop 有一段 Galaxy Store 独家期
Samsung says Adobe Photoshop for Tablet comes preloaded in the Galaxy Picks folder and will launch exclusively through the Galaxy Store for at least six months starting October 7. The company also lists a four-month trial of Photoshop Premium Mobile with 100 monthly generative credits for eligible S12 buyers. In Korea, Samsung describes a six-month Google AI Pro benefit alongside other launch promotions. Each offer has a different provider, duration, and eligibility, so they should not be added together as a permanent part of the tablet's value.三星表示，Adobe Photoshop for Tablet 会预装在 Galaxy Picks 文件夹中，并从 10 月 7 日起至少六个月只通过 Galaxy Store 上架。公司还列出符合条件的 S12 买家可享四个月 Photoshop Premium Mobile 试用，每月含 100 个生成式积分。韩国三星公告还介绍了六个月 Google AI Pro 权益及其他本地促销。每项优惠的服务方、持续时间和资格都不同，不应把它们相加后当成平板的永久价值。
The Photoshop exclusivity is a time-limited distribution arrangement, not a promise that the app remains Galaxy-only. Samsung's footnote says Adobe may launch it in other app stores after the six-month period. The four-month Premium trial also ends; a user who depends on a paid editing feature should compare the ongoing subscription cost before choosing a tablet. The Android Authority launch article covers the hardware and price, while Samsung's own footnote is the source for this software window.Photoshop 独家期是限时分发安排，并不意味着应用之后一直只能在 Galaxy Store 下载。三星脚注说，六个月后 Adobe 可能在其他应用商店发布。四个月的 Premium 试用也会结束；如果你依赖付费编辑功能，应先比较试用期后的持续订阅成本。Android Authority 的发布报道介绍硬件和价格，而这一软件安排以三星自己的脚注为依据。
The battery headline describes video playback续航宣传指的是视频播放测试
Samsung lists up to 23 hours of video playback for the S12 Ultra and up to 21 hours for the S12+. Its U.S. footnote describes a local 720p video test in the default player at 162 nits, with Wi-Fi and mobile networks turned off. Samsung says results vary with settings, usage, and other factors. That test is useful for comparing the company's stated method across its models, but it is not a promise of a 21- or 23-hour workday with video meetings, drawing, downloads, and wireless accessories.三星列出 S12 Ultra 最长 23 小时视频播放、S12+ 最长 21 小时。美国页面脚注说明，测试使用本地 720p 视频和默认播放器，屏幕亮度 162 尼特，并关闭 Wi-Fi 与移动网络。三星表示结果会因设置、用途和其他因素变化。这个测试口径有助于理解厂商如何比较自身机型，但不能保证在视频会议、绘图、下载文件和连接无线配件的工作日里也能使用 21 或 23 小时。
The 45-watt adapter needed for the listed roughly 95-minute full charge is sold separately. Buyers should check whether their existing charger supports the required output and cable, or include the adapter in the local cost. The tablet's thin body and large display may suit a desk routine, but video playback in airplane mode will not reproduce that routine. No independent battery test was included in the launch coverage used here.三星还表示，使用 45W 适配器时约 95 分钟可从 0% 充至 100%，但该适配器需要另购。购买者应确认现有充电器和线缆是否达到所需输出，或把适配器费用加入本地预算。平板的薄机身和大屏幕可能适合桌面使用，但在飞航模式下播放视频的测试环境无法代表日常工作。本文使用的发布报道中没有独立续航测试。
Offers and configurations depend on the country促销和容量都要按国家核实
Samsung's Korean newsroom says the tablets went on sale there on October 7 and lists different price ranges for the Ultra and Plus based on memory and storage. It also describes content subscriptions, accessory discounts, and a review-reward promotion running through October 31. Those terms are local and time-limited. The U.S. launch announcement emphasizes included S Pen, six-month Google AI Pro, and Photoshop availability. A shopper should not assume an offer in one country is included in another country's box.三星韩国新闻稿说，两款平板于 10 月 7 日在当地开售，并按内存和存储容量列出 Ultra 与 Plus 的不同价格范围。它还介绍了截至 10 月 31 日的内容订阅、配件折扣和用户评价活动。这些条款只适用于韩国和注明的活动日期。美国发布内容重点是附赠 S Pen、六个月 Google AI Pro，以及 Photoshop 上架安排。不能假设某一国家的促销也会放进另一国的包装盒。
The U.S. model's starting price reported by Android Authority is not the price of every capacity or keyboard bundle. A Korean Plus offer with a subscription benefit is not a U.S. tablet price either. Before checkout, match the model, RAM and storage, Wi-Fi or cellular option, keyboard, charger, taxes, and promotional trial. If the exact capacity is not displayed on the store page, leave the comparison unresolved until the retailer identifies it.Android Authority 报道的美国起售价并不代表每种存储版本或含键盘套装的价格。包含订阅权益的韩国 Plus 促销也不等于美国平板售价。付款前应核对具体型号、内存和存储、Wi-Fi 或蜂窝网络版本、键盘、充电器、税费和试用资格。如果商品页面没有标明具体容量，应等零售商确认之后再完成价格比较。
When the Ultra makes sense什么情况下 Ultra 更合适
The Plus is the more practical choice for someone who wants a large screen for reading, handwritten notes, video, and occasional keyboard use but still carries the tablet between rooms or classes. The Ultra fits people who regularly keep several work surfaces visible, draw on the largest panel, or need the 14.6-inch area for a specific creative app. The included S Pen helps both models with handwriting; it does not erase the size and price gap.如果你想要大屏来阅读、手写、看视频，偶尔搭配键盘使用，但仍会在房间、课堂或办公室之间携带，Plus 会更实际。Ultra 更适合经常同时打开多个工作区域、需要最大绘画画布，或某个创作应用确实需要 14.6 英寸空间的人。两款都附赠 S Pen，可以手写；这并不会消除它们在尺寸和价格上的差异。
A buyer can make the choice by testing the screen and pricing the full setup. Hold each size in the posture where it will be used, check the apps and keyboard layout, then add the separate adapter and keyboard if needed. Confirm the local configuration and the end date of any trial. The S12 launch gives each model a clear role, but the value depends on whether the larger screen or the bundled software changes a real daily task.可以把屏幕试用和完整套装价格结合起来做选择。按你真正使用的姿势拿一拿两种尺寸，试试常用应用和键盘布局，再把需要的另售充电器与键盘计入预算。确认当地容量配置和试用结束日期。S12 发布为每款机型确定了不同定位，但值不值得买，要看大屏或软件权益是否能改善实际每天要做的事。
