Display & Screen Terms
The display section of a spec sheet is packed with acronyms. Here's what the most common ones actually mean in everyday use.
AMOLED / OLED: Both refer to screen types where individual pixels generate their own light. The result is deep blacks and punchy colors. AMOLED is Samsung's branded version of OLED technology — functionally similar in most consumer contexts.
LCD / IPS LCD: Liquid Crystal Display technology that uses a backlight. Generally not as contrast-rich as OLED but often accurate and reliable. IPS (In-Plane Switching) is a higher-quality LCD subtype with wider viewing angles.
LTPO: A display technology that allows the refresh rate to change dynamically — dropping as low as 1Hz when showing a static image and rising to 120Hz during fast-moving content. This flexibility can improve battery efficiency.
Nits: A unit measuring screen brightness. More nits means easier readability in direct sunlight. Screens above 1,000 nits are generally considered good for outdoor use.
Resolution (e.g., 1080p, 1440p, FHD+, QHD+): The number of pixels on screen. Higher resolution means finer detail, but the difference is most noticeable on larger screens or when viewing fine text.
PPI (Pixels Per Inch): How densely pixels are packed. A higher PPI typically means sharper text and images. Most people cannot distinguish individual pixels above roughly 300 PPI at normal viewing distance.

Camera, Connectivity & Durability Terms
Camera and connectivity specs are where marketing language gets especially dense. These definitions cut through it.

Megapixels (MP): The number of individual light-capturing points in a camera sensor. More megapixels do not automatically mean better photos — sensor size, lens quality, and software processing all play major roles.
Telephoto / Periscope lens: A secondary camera designed for optical zoom. A periscope design folds the optical path inside the phone body to achieve longer zoom ranges without a thicker camera bump.
ToF sensor: Time-of-Flight — a depth-sensing camera that measures distance by calculating how long a light pulse takes to bounce back. Used for improved portrait mode blurs and augmented reality features.
Wi-Fi 6 / Wi-Fi 6E: The current mainstream generation of Wi-Fi, offering faster speeds and better performance in crowded environments. Wi-Fi 6E adds access to the 6GHz frequency band for even less interference.
Bluetooth version: Higher Bluetooth versions (5.0, 5.3) improve range, speed, and power efficiency for wireless accessories like earbuds and speakers.
USB-C / USB 3.2 / Thunderbolt: USB-C describes the connector shape. The version number (3.2, 4) indicates transfer speed — important if you plan to move large files or use the port for video output.
Specs Vary by Region and Carrier
Some spec sheet features — particularly 5G band support, eSIM availability, and storage configurations — can differ between the same phone model sold in different countries or through different carriers. Always confirm the exact specifications for the version sold in your region before making a decision.
UWB (Ultra-Wideband): A short-range wireless technology enabling precise spatial awareness — used for features like directional finding for accessories or secure car unlocking.
