This may have been an issue in how we invoke the native binary from the app. I pushed an updated version of the apk on Friday morning (June 29) that should address this. Maybe you can remove the app and redownload it?

Thanks,

Ok, I did it and I guess this time it worked. I was able to see the output.
I did the test with apps closed and rebooting the device, too (as recomended in output. This was a result after restarting).

Yes, this looks better. I have seen similar output before and it seems that (some) galaxy devices disabled access to some of the files in /proc/. This makes it harder for our app to figure out when to start hammering. I will have to think about how to address this.

In general, I think that it is a good strategy from Samsung to disable read access to those files.
