My 10" Samsung Galaxy Tab4 has quit sending log data during my testing. My 7" tablet is still sending log data when I test the same code there. I have tried installing and logging with different apps but am not getting log data on the 10" from any. It has been logging today but has now stopped. I'm compiling in release mode with vers 3.8. It stopped during my testing trying to get device info using the logic in beginners guide. I have not changed any tab settings (I know, I've heard that one many times, too). The only setting I can find anyway is the accept changes from external sources and that one is checked. I've tried re-booting the tablet. I even wrote a one button click app and it won't log on the 10" either but will on the 7".
