hi all! not sure if anyone has experienced this. i tried a number of tracker apps for sports like endomondo, sportstracker, my tracks, and none of them seem to get past 3 mins in sleep mode, when the gps signal goes dead. i can't find any settings to alter neither on the phone OS or on my app killer (taskmanager 2.1.2). Anyone has got a clue where to look? cause 3 mins ain't much of a work out!
