Screen Distance FAQ: Every Question Answered

Quick answer

Hold your phone 13–20 inches (33–50 cm) from your eyes; closer than 12 inches (30 cm) is too close. Android has no built-in Screen Distance feature like iPhone, so you'll need a distance alert app. Below are the most common questions, grouped by topic.
