One screen.
Every readable field.
DeviceInfo Viewer is a tiny read-only Android app. It reads what the OS will surface — 15 categories, from emulator / root detection through cell towers, sensors, GPU strings, install source — and lays it out flat. No analysis, no score. Every value long-press-copyable, so what you see is what you paste into your report.

Which app do you want?
Two apps, two audiences. They're written by the same team and share the same 84K-device reference database, but they exist for different jobs.
Engineer / researcher
DeviceInfo Viewer (this one)
Raw dump of everything Android will surface, laid out flat. No analysis, no score. For debugging, privacy audits, anti-fraud research. Tiny APK.

👁️
Read-only readout
Reads system state, doesn't modify it. Nothing to persist, nothing to break. You're inspecting your own phone, not changing it.
🪶
Tiny APK, zero deps
Pure Java + framework API. No native .so,
no third-party libs. Universal ABI, drops onto any device.
📄
Values match what apps see
Same framework APIs any third-party app calls — so what you read here is what other apps read about your device.
🛡️
Risk signals up top
Emulator / Root / VPN / debug status shown as coloured badges at the top of the screen. Green = clean, red = hit.
📋
Long-press any value to copy
Fingerprint / getprop / /proc/cpuinfo / sensor list — every value is one long-press away from your clipboard.
📱
Android 5 → 16
Compat from API 21 through API 36. Fields locked down by newer Android are explicitly labelled (e.g. IMEI "restricted since Android 10").
15 dimensions, one screen
Everything on one long scroll of cards. Each section collapses independently.

Permissions
What each permission is for
Every runtime permission below maps to a specific field on the panel. Deny any of them and the corresponding fields just show "not granted" — the rest of the app keeps working.
Permission use
| READ_PHONE_STATE | Carrier, SIM, network type |
| ACCESS_FINE / COARSE_LOCATION | Cell towers, WiFi scan list, lat/lng |
| ACCESS_WIFI_STATE / ACCESS_NETWORK_STATE | WiFi + network state |
| BLUETOOTH_CONNECT | Bluetooth adapter name (one emulator signal) |
| READ_MEDIA_IMAGES / VIDEO (13+) or READ_EXTERNAL_STORAGE (≤12) | Count photos / audio files |
Strong identifiers (IMEI / IMSI / serial etc.) are locked down on Android 10+. Normal apps can't read them. The panel labels these fields as "restricted" honestly.

FAQ
Why does "debug state" show as "yes"?
That check is "is this app being debugged / built as debuggable" — nothing to do with your phone's USB debugging switch. A release build shows "no". For the phone-level USB debugging state, look under 🧩 System state → ADB debug.
Why can't I read IMEI / serial?
Android 10 (API 29) blocked normal apps from reading those. It's a system-level restriction, not a Viewer bug. The panel labels these fields "(restricted since Android 10)".
Some fields show "not granted"?
The corresponding runtime permission wasn't approved. Viewer doesn't nag — it skips those fields and shows the rest.
Grab it. Read every field.
Free. No account. Read the source truth of any Android you can install it on.
