I just noticed a problem with Astro. I am using a SD card brought from several phones with the last 2 being HTC EVO and 3D. I have several apps backed up on the card but in the Epic 4G Touch although the files are present on the card Astro does not show any backed up files. This is not a major problem because I can install these apps from other sources or the market. A big problem though is I have a couple of apps with the data backed up and those programs do not recognize there backups either. I am wondering if Samsung's media scanner process is interfering with old data stored on the card. Previous images and music files are available though. Bluetooth, I have noticed that when my phone is connected to my car audio via 3,5 MM cable I no longer have bluetooth capability through my earpiece for phone communication. As soon as I unplug the audio cable bluetooth returns to the earpiece. Any thought or suggestions on the above would be greatly appreciated.
