Camera Test & Mic: DeviceGPT

🔍 WiFi speed test, camera test, mic test, battery health, AI phone diagnostics — one tap on Android. DeviceGPT scans your device and explains the result in plain English. No root.

After every scan, tap Ask AI to get instant fixes via ChatGPT, Gemini, Claude, DeepSeek, Perplexity, Copilot, Grok, You.com, or Replika. Raw scan results stay on your phone unless you share them; scores and phone model go to the leaderboard.

🩺 App Doctor — "WiFi Connected But No Internet"
Connected to Wi-Fi but nothing loads? App Doctor finds out why:
• Type any website; DeviceGPT tests it 4 times, so a site that fails only sometimes cannot hide
• Tests the normal connection and the in-app browser, so you see when Android System WebView is the problem
• 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
• FPS and frame-drop monitoring

🛡️ 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.

📱 Phone Health Check — One Scan
• Health score across battery, storage, RAM, temperature and security, plus full device info

📊 Phone Condition Check & Resale Report
Generate a certified phone report for resale, support tickets, or proof of condition. Signed (ECDSA, Android KeyStore), tamper-evident, with a shareable verification code.

🇧🇩 Bangladesh — Is This Phone Official? (BTRC IMEI Check)
Before you buy or sell a phone in Bangladesh: dial *#06#, type the IMEI, and DeviceGPT checks the digits, then opens BTRC's check — SMS KYD to 16002, *16161#, or the NEIR site. The answer is BTRC's, not the app's. Shown on phones in Bangladesh or with the app in Bangla.
