App Doctor finds out why: • Type any website and DeviceGPT tests it 4 times — a site that fails only sometimes cannot hide behind one lucky check • Tests through both the normal connection and the in-app browser, so you see when Android System WebView is the real problem and Chrome is fine • Shows your DNS servers, whether Private DNS or a VPN is active, and whether the network is holding you at a sign-in wall (captive portal) • Reports pass count and average latency, not a single green tick 🚀 WiFi & Network Speed Test • WiFi speed test — download, upload, ping, jitter • Network speed test for cellular + Wi-Fi 🔋 AI Battery Health — What Android Doesn't Show • Battery health status (Android's reading) and temperature • Live device power draw in watts (real physics: P = V × I) • Estimated component breakdown (model-based): display, cellular, RAM, Wi-Fi • App screen time — Android does not report per-app battery use, so this ranks screen time, not battery • Charging behavior and cycle tracking • Export battery data to CSV or Ask AI for explanation 🎤 Mic Test, Camera Test, Screen Test • Mic test / microphone test — measures the room noise floor, your voice level, and plays the recording straight back so you hear what callers hear. The recording never leaves your phone • Camera test — camera not working? Front and rear check, focus, colour cast • Screen test — dead pixel test and stuck pixel test with 9 full-screen colours plus a grid for scratches. Your phone cannot detect its own dead pixels, so you look and DeviceGPT records your answer — never a guessed score • Phone hardware test: touch screen test, plus GPS status and sensor list (accelerometer and more) • FPS monitoring and frame drop detection (Choreographer API) 🛡️ Zero Trust Dashboard — Phone Security Audit A three-section audit scoring your device 0–100: • App Privacy Risk (35%): keyboards and accessibility services that can read your screen or keystrokes, apps reading your advertising ID, apps holding mic/camera/SMS, sideloaded apps • Network Trust (35%): DNS manipulation, SSL hijack (MITM), transparent proxy, private DNS • Device Integrity (30%): root status, sideloading, developer mode, overlay permissions, notification listeners 🔌 AI Bridge — Let Claude or Cursor Read Your Phone Pair a desktop AI client over your local network with a PIN or QR code. It reads live device data through MCP — no cloud, no account. 🤖 AI Explains Your Phone in Plain English "Battery is overheating — close background apps."
