Device Info & Hardware Test

Device Info & Hardware Test shows your phone's specs and live system info in one clean app, and helps you test the hardware step by step. Check phone info, CPU info, RAM, storage, battery health, display, camera, network and sensors, then run guided hardware tests. Useful when you buy a used phone, sell your phone, or want to understand a problem.

DEVICE HEALTH AT A GLANCE

• A device health score based on battery temperature and status, storage and RAM use, CPU load, your test results and security settings

• Live RAM usage and CPU frequency charts on the home screen

• A short note that points out the main issue, if there is one

HARDWARE TEST: 18 GUIDED CHECKS

• Display color and dead pixel check, and a full-screen multitouch test

• Flashlight, loudspeaker, ear speaker and microphone level test

• Camera, vibration, charging status, Bluetooth and NFC

• Fingerprint test, volume up and volume down buttons

• Proximity, light sensor and accelerometer checks with live values

• Wi-Fi / network connection check

• Mark each result as pass or problem; results are saved so you can see what is left

BATTERY INFO

• Battery level, health status reported by Android, temperature and voltage

• Charging status, power source, technology and design capacity

• Current now, average current, charge counter and estimated time to full (when your phone supports it)

CPU AND GPU INFO

• Live speed of every CPU core

• Chip name, architecture, ABI, cores, governor, CPU features and CPU temperature

• GPU renderer, vendor and OpenGL ES version

SYSTEM INFO

• Device details: brand, model, manufacturer, board, hardware, build ID and fingerprint

• Operating system: Android version, SDK, security patch level, kernel version, SELinux status and uptime

• RAM and storage usage

DISPLAY AND CAMERA INFO

• Resolution, refresh rates, density, screen size, aspect ratio, HDR and wide color support, brightness and screen timeout

• Front and back camera details: megapixels, flash, hardware level, focal length, aperture and sensor size

NETWORK INFO

• Wi-Fi details: IP address, gateway, frequency, signal strength, link speed and Wi-Fi standard

• Internet status, metered connection, VPN, DNS servers, interface and MTU

• Mobile network type, operator, SIM state and roaming (after you allow phone permission)

SENSOR TEST WITH LIVE GRAPHS

• See every sensor on your phone with vendor, range, resolution and power

• Tap a sensor to watch a live graph, then share or save the readings as CSV

DEVICE SAFETY CHECK

• Local check for root access, screen lock, developer options, USB debugging, unknown app installs and encryption

• See how many apps use sensitive permissions such as camera, microphone, location, contacts, phone or SMS

• Quick links to the matching system settings

APP INSIGHTS

• Browse installed and system apps with their version

• Filter apps that request sensitive permissions, open app details or launch an app

EXPORT REPORT

• Create a full device report and save it as TXT or PDF, or share it

• The report is generated on your phone

GOOD TO KNOW

• No account needed. Device details, test results and reports stay on your phone and are not sent to our servers.

• The app shows ads. Our ad partner may process data such as device identifiers; see the privacy policy.

• This app reads and tests your phone. It does not boost, clean or repair anything.

• Some details depend on your Android version, phone maker and the permissions you allow.
