AppFixing Device Doctor
Quickly test a phone before buying it
Free browser-based phone diagnostic test from AppFixing. Check touch, screen, speakers, microphone, sensors, battery, camera, and performance in minutes.
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 🙏
