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, temperature, degradation signals • Live device power draw in watts (real physics: P = V × I) • Component breakdown: 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, cycle tracking, fast vs slow charge comparison • Export battery data to CSV or Ask AI for explanation 🎤 Mic Test, Camera Test, Screen Test • Mic 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 — front and rear camera check, focus, and colour cast diagnosis • 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: touchscreen, speakers, GPS, accelerometer • FPS monitoring and frame drop detection (Choreographer API) • Charging test — speed, temperature, current draw 🛡️ Zero Trust Dashboard — Phone Security Audit A three-section audit scoring your device 0–100: • App Privacy Risk (35%): keylogger detection, screen-recording apps, hidden apps, on-device malware scan, mic/camera abuse, ad tracker detection • Network Trust (35%): DNS manipulation, SSL hijack (MITM), transparent proxy, deep packet inspection, ISP tracking, private DNS • Device Integrity (30%): root status, bootloader, sideloading, developer mode, overlay permissions, notification listeners 🤖 AI Explains Your Phone in Plain English Other diagnostics apps show numbers. DeviceGPT explains them: "Battery is overheating — close background apps." "Wi-Fi jitter may affect gaming — restart router." We prefill a smart, context-aware prompt for your AI of choice. 📱 Phone Health Check — One Scan • Phone health score covering battery, storage, RAM, temperature, sensors • Device info: specs, system details, build info 📊 Phone Condition Check & Resale Report Generate a certified phone report for resale, support tickets, or proof of condition.
