Battery, Mic Test: DeviceGPT

🔍 WiFi speed test, battery health, mic test, 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. Nine AI platforms. Your scan stays on-device unless you share it.

🚀 WiFi & Network Speed Test
• WiFi speed test — download, upload, ping, jitter
• Network speed test for cellular + Wi-Fi
• Real-time signal strength and bandwidth
• Latency and packet loss for gamers

🔋 AI Battery Health — What Android Doesn't Show
Android has no built-in battery health screen. DeviceGPT fills the gap:
• 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 — see which apps you use most (Android does not report per-app battery use, so this ranks screen time, not battery)
• Charging behavior and cycle tracking
• Battery tester for fast vs slow charge comparison
• Export battery data to CSV or Ask AI for explanation

🎤 Mic Test, Hardware Test, Sensor Test
• Mic test — input level, noise floor, instant playback
• Phone hardware test: touchscreen, speakers, camera, GPS, accelerometer
• FPS monitoring and frame drop detection (Choreographer API)
• Touch latency measurement
• 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

Asked "is my phone hacked?" — the Zero Trust Dashboard gives you a scored, structured answer.

🤖 AI Explains Your Phone in Plain English
Other diagnostics apps show numbers. DeviceGPT explains them:
"Battery is overheating — close background apps."
"Mic was used last night — revoke app permissions."
"Wi-Fi jitter may affect gaming — restart router."
We prefill a smart, context-aware prompt for your AI of choice.
