Hi everyone 👋 I built this tool because I was buying used phones and got tired of installing random apps just to test basic things like the screen, touch, or microphone. So I created a browser-based solution that works instantly — no installation needed. The goal is simple: Quickly check if a phone has hardware issues before buying it or when something feels off. Right now it supports: - Touch testing (dead zones) - Screen checks - Audio (mic & speaker) - Sensors and basic performance Everything runs locally in the browser — nothing gets uploaded. I’d really love your feedback: 👉 What tests would you expect to see? 👉 What would make this more useful for you? Thanks 🙏
