Does anyone else have this issue? When using Google Nav for more than about 15 minutes with GPS on, the nav app would freeze up and need to be FC'd? Also, when using apps that require GPS for more than 15 minutes like Cardio Trainer, the app will also freeze up and FC? It appears to be a pattern with GPS locking up my apps... The only task-killer-type of app I use is MinFreeManager and set to Aggressive. Could that be the problem? What exactly does that app do besides doing some magic to free up mem? or am I totally off?
