Capability Lab

• Device Capability Lab 1.0 — an Android hardware and software capability inspector.
• Fifteen labs, each reading from the real system service rather than a lookup table: Android platform, display, graphics, CPU, memory, storage, cameras, media codecs, audio, sensors, connectivity, USB, biometrics and security, DRM, and hardware features.
• What makes it different Most device-info apps collapse three very different situations into one "not supported". This one keeps them apart:
• Queried — not supported by this hardware. The API answered, and the answer was no. Requires API 34+ — this device is running API 28. The hardware may well have it; the running Android version has no API to ask. Not exposed by Android. No API exists at any level. Named anyway, with the reason. PackageManager.hasSystemFeature("android.hardware.uwb") returns false on Android 9 — not because the device lacks ultra-wideband, but because the platform has never heard the name. Every feature row here is gated on the API level that introduced its constant, so an older device says so instead of answering no.
• Every row shows the exact API call behind its value, so any claim in the app can be checked against the platform documentation.
• Also in this release Dashboard scorecard across eight domains, with no invented "performance score" Filterable capability matrix over every check Snapshots you can save, rename and compare — the diff reports added / removed / changed / unchanged Export to JSON, plain text or self-contained HTML Instant search across values, API names and explanations
