LOLLLLLLL Samsung? Don't get me started on OVERRATED Samsung Wind. lol I owned the S5 and the S7 (also S7 Edge for a couple weeks). S7............the audio quality on that phone was ABYSMAL. Saying it was awful would be too nice. The call quality was complete TRASH too, and that was WITH HD Voice. The speakers rendered drum sounds like shots from a laser gun! They're like the worst-rated phones for audio. Plus if that wasn't enough, the S7 had a bug in its MicroUSB driver, so when I'd connect my Oppo HA-2 amp/DAC through it, it would cause "skips" in my music every 3-5 minutes. I had that phone for 4 mos, and I couldn't WAIT to get rid of it after 2-3 weeks. lol Only kept it to wait for new Sony and HTC phones that were coming out soon. I hope now that they bought Harman Kardon (which also owns AKG) that they'll improve that, but as of yet, I've read nothing to indicate that they've improved anything.
Ok back to your question lol................I think I already answered this earlier, but DON'T WORRY about playing "Hi-Res" music. Just worry that the player and the phone are built with QUALITY parts, including audio tech. LIKE the 10. lol If you or someone you know gets a phone that isn't like this, then just buy a solid amp/DAC like the AudioQuest DragonFly Black or upgraded Red, and be done with it. lol
