Re-branded KalturaDeviceInfo to provides GSF id (needed for Google uncertified devices) and checks about Widevine, Treble, a/b & media decoders (and all others possible device system definitions).
uses-permission android:name=
android.permission.WRITE_EXTERNAL_STORAGE android:maxSdkVersion="18" 
This app is a basic json example, it shows how much any app, can silently retrieve devices characteristics, but also simply provides :
  • testing any device sample, without Dev./Options unlocked, before purchasing (live or via email request to the seller)
  • add-on for static passive reporting in AOSP roms (conversely to active stats)
  • Treble advanced reviewing specifics
  • all-in-one floss without internet leak
(*.json can be easily browsed/parsed with FirefoxPC)


If you want some added, let me know, but due to privacy, I won't add any requiring <INTERNET> or <READ_PHONE_STATE> (or <READ_LOGS>)

° New Version: detection getprop for Treble & A/B seamless update + designation Soc & Kernel version
° JSON report doesn't include any {action}->privateIDs ; feel free to Post everywhere
° ... SharedLibs, Features, SecurityProviders, /proc/meminfo, GLESversion +...

° Services & init_svc & {action}-> getprop
° New Treble checks (ro.vndk.version) & ScreenMetrics
° improve gps.conf & treble + matrix
°/vendor detection, mounts, camera & cameraAPi2... (and Matrix_bug)
NEW RELEASE RC6: CameraAPi2 global specs, Display HDR modes (and etc/gps.conf miss in "private" dialog-box))

nota: works on JellyBean and up ; with Oreo, Android_id is discontinued, and Serial_id deprecated due to <read_phone_state> permission.

Can you explain what the purpose of this is? What we would use this for?

Hi, thanks for your interest, I'm huge xda{news} fan (everyday congrats), and was referring to
-GSFid , this app throws a json on screen with finger touch copy/select/share; so users can copy it, also if Firefox is installed ( Fennec or Klar), on Lollipop and up, the share button to Firefox will straight open Google re-certification page (1st link in json).
-Widevine real level : (and others Oneplus5...) thanks to Kaltura prim-origin, the app tests all possible drm inclusions.
-cpu soc64 without arm64 support: (thx to @mattwhite7102) some low cost oem provide devices with arm64 cpu without arch64 support
-Treble detection
-A/B seamless update

I will do my best to get this app auto-built by F-Droid, thus before buying a low cost device (example Treble project), buyers can ask sellers to process it, and send them this json by email. ( ? same for each new xda forum's device heading ?).

Finally, every (closed source) app with <internet> permission can leak this data to the net: it just visualizes this.
In that same purpose I'm also on releasing an upgrade of ApplicationsInfo with multiple additions, and without <internet> or other "excessive" permission : . (but untested on new Pie Update Inactive Apps screen to show buckets )

Matrix ckick causes freeze
@oF2pks thanks for this! I'm no beginner when it comes to Android modding and such (check my sig) but the amount of info your app provides is overwhelming. More stuff for me to learn

PROBLEM: When I click on "Matrix" the app freezes, then I get the error "Kaltura Device Info is not responding".

MatLog output attchd

BTW, I learned about this because of link at
