I hope this thread hasn't been posted yet, but if it has I apologize... I recently picked up my SGS3 a week ago (used to have a thunderbolt) and I love it. However, I am having issues with a few apps closing when I am attempting to "screen save" my phone... I run and lift everyday and when I attempt to use endomondo, it works great- right up until I shutoff the screen to start my exercise, in which case it just closes the application! The same problem happens with my Sirius XM radio! I refuse to believe I have to keep the display on at all dimes for these applications to run as it would just destroy the battery. Someone please help me fix this!
