Developers tools: System Tracing tool not working correctly #2206

Open tujh2 opened 1 year ago

tujh2 commented 1 year ago

Android has built-in System Tracing tool (In Developers options). And this is not working on my device with GrapheneOS. It generates empty trace files. I tried to capture trace using Android Gpu Inspector and it stucked on "Initialising".

Also System Tracing->Categories has empty list (see screenshot).

On my other non-google device with LineageOS it has many options. (see screenshot)
