i use the new Racechrono v5.0.4 and a Samsung S3 mini. Before roughly one year (older Racechrono version) the datalogging with GPS (818XT, 5 Hz) and a DIY-RaceDAC (50 Hz) worked perfect. Now the GPS logging still works, but the RaceDAC logging stops after a few minutes or sometimes seconds. With a new smartphone (Samsung A5 2016) everything works fine. When i'am trying an other new low budget smartphone (Wiko Sunny), i have the same problem like with the S3 mini.
Do you a idea?
Best regards, Jakob
