What is replacing com.oem.autotest with \0om.oem.autotest in /system/vendor/lib64/hw/com.qti.chi.override.so for? #2

I ran strings on my com.qti.chi.override.so and com.oem.autotest is nowhere to be found.

What is it for?

sean6541 commented 3 weeks ago

com.oem.autotest is the package id of a internal app OnePlus uses for testing. It gets access to a bunch of hidden camera API's. When an app accesses the camera, strncmp is called to compare the package id to the string com.oem.autotest. strncmp only compares up until it reaches a null character, so by replacing the first character of the string com.oem.autotest with null, all apps get access to these hidden API's.

As for why it can't be found, what device is your file from?

Ah, so you're saying that com.oem.autotest is the super-priviledged package that we all now imitate?

OnePlus Ace 2 Pro

I guess it how has some different options for restricting camera access.

Yes, exactly. Unfortunately, full resolution is restricted differently depending on the device and chipset.
