Hi guys! I wanted to participate in your experience: Recently I put some files to my Android mobile (Samsung Galaxy SII) in addition to the Ogg/Vorbis ones: Speex, flac, Opus Unfortunately it seems the Music player crashes periodically since then. (Needless to say that it cannot play speex and Opus) You'll notice that your list of albums (normally at 180) suddenly becomes very short (1 album) while the player rebuild it index (it seems). Also there is an "attention icon" in the top bar for a second or two saying the memeory card was unexpectedly removed (I had an erratic "the memory card is defective" aa long time before also) I have the impression that after removing speex and opus things get better. My memory card is the maximum supported size (32GB), and I wonder if some have similar experience using mostly Ogg/Vorbis and a large collection of titles. Maybe you can recommend an alternate player that is free (in the sense of "open") and not an ad bot or spy bot. BTW: How many level for volume control does your mobile/player have? My old Samsung YEPP has 30 levels (Good), my Symbios Moto Z8 hat 8 levels (terrible!), and the Galaxy Sii has 12 levels (barely sufficient). I want to enjoy the sound, not ruin my ears.. Thanks Ulrich
