NOTE4 / BLACK & WHITE E-INKVOICE TO ACTION
Say it once.
Skip the tedious steps.
Press the front button and say what you need to do. NOTE4 turns speech into tasks and reminders, making capture faster and keeping important things visible.
Speak the time and task naturally, without opening your phone or finding an app.
The task is organized and stays visible whenever you need it.
“Remind me about the meeting at 3 p.m.”
Voice recognition, task creation, and synchronization require a network connection. Available capabilities depend on the current service version.

Actual battery life varies with Wi-Fi conditions, refresh frequency, voice usage, screen content, and battery condition.
