which model introduces an always-on display as a new feature?

The model widely recognized for introducing an always‑on display as a new feature in mainstream phones is the Samsung Galaxy S7 series (Galaxy S7 and S7 Edge).

Quick Scoop: Always‑On Debut

• In 2016, Samsung launched the Galaxy S7 lineup with an always‑on display that showed time, date, and notifications even when the screen was “off,” using AMOLED to keep power drain low.

• This implementation is the one most tech sources point to when crediting a phone that “introduced” always‑on display as a headline feature for modern smartphones.

Why That Model Matters

• Earlier devices and other form factors experimented with similar ideas, but the Galaxy S7 is commonly cited as the launch point for today’s always‑on trend on Android phones.

• Since then, always‑on displays have spread across Android brands and later appeared on iPhone Pro models starting with the iPhone 14 Pro and 14 Pro Max.
