I’m looking for a suite of open source tools to test android devices. Ranging from general screen / sensors / gps etc along with cpu / storage / memory and gpu stress testing for diagnostic purposes. I have found https://github.com/rohanagarwal94/Hardware-testing and wondered if it is reputable as the apk is hosted on dropbox. It looks like it will do much of what I am looking for. But I am having trouble finding open source hardware stress testing software for cpu / storage / memory and gpu.

I am running grapheneos and only want to run open source software. I have yet to experiment with multiple user profiles where I could have the option of running closed source applications but just thought I’d mention that in case for hardware testing that is the only option.

Thanks for reading.
