Device Id

Device Id reveals everything about your Android phone—and exposes what apps secretly know about you. With over 1 million users relying on it for device information, hardware diagnostics, and privacy insights, Device Id is the only comprehensive tool that combines complete device profiling with built-in privacy scanning.

UNDERSTAND YOUR DEVICE'S PRIVACY EXPOSURE See exactly which device identifiers your installed apps can access. Device Id distinguishes between permanent IDs and resettable ones, then assigns risk badges—public, resettable, restricted, or permission-gated—so you understand what's truly trackable before granting app permissions. This privacy scanner shows you the data footprint your device leaves behind.

COMPLETE DEVICE INFORMATION AT YOUR FINGERTIPS Access Android ID, OAID, GSF ID, IP address, IMEI, serial number, and build details in seconds. Instantly view your manufacturer, model, hardware specs, Android version, and API level. Check root detection status and compare your phone specifications today against previous snapshots to spot unauthorized changes—invaluable when buying used phones or verifying device authenticity.

HARDWARE DIAGNOSTICS & REAL-TIME MONITORING Run instant hardware tests including multi-touch responsiveness, dead pixel scanning, speaker and microphone quality checks, vibration response, camera flash, and GPS accuracy. Monitor live CPU usage and frequency, thermal status, battery temperature trends, and RAM consumption. Get detailed battery health metrics including design capacity versus current capacity, charge cycle counts, and voltage readings—all updating in real time.

NETWORK, DISPLAY & SENSOR INSIGHTS Check Wi-Fi signal strength, cellular carrier information, network type (2G through 5G), and public IP details powered by ipinfo.io. View display refresh rate, HDR capabilities, and color gamut support. Monitor accelerometer, gyroscope, magnetometer, light, proximity, and pressure sensors with live readouts.

SHARE & COMPARE WITH CONFIDENCE Generate one-tap shareable spec reports as images—perfect for selling your phone with verified specifications or providing warranty proof. Save device snapshots at any moment and compare them later to detect hardware or configuration changes. Use the resizable home screen widget for instant battery percentage, RAM usage, and Android ID access without opening the app.
