A Billion Phones and Even More People
summary
Billions of new mobile users land on slow networks and cheap phones: India has ~627 million internet users (45% penetration) and Facebook reaches ~500 million there, many devices with <2 GB RAM and real-world bandwidth around 3–4 Mbps. Recommend internationalize into local scripts, build light modes (Uber Light drops maps to save bytes), test on low-end Chinese devices and flaky Wi‑Fi, provide an onboarding demo for novice users, and prioritize delivering core functionality under high latency and low memory.
