Anybody can recommend me an AirDroid alternative? AirDroid is only recognizing about 11 GB of my 64 GB SD card for some reason. A little online research shows me that this is a known flaw with some phones. I just got the S4 Active and I'd like to transfer over my music connection wirelessly if possible. I had no luck with iSyncr and DoubleTwist (both wired connections) when I owned the G Pro for a few days last month. Keep in mind I'm using a Mac, if that matters. A huge thank you to anybody in advance if you can help me with this.
