I have the same issue. iheart radio with constant skips and various times between skips. I tried many of the so called solutions here but to no avail, nothing works! 1000$ phone you have got to be kidding me.
This is part of the solution: "They finally exchanged the phone. New phone worked till software update and now has same problem."
Seems to me that one of the software updates is actaully causing this problem to manifest so we have no choice but to deal with it.
Samsung, you need to find out which part of the software update is causing the issue. No amount of having it 'repaired' will make any difference when a brand new phone has the same problem AFTER being updated. You will need to have one of your technicians analyze the problem starting with a new non-updated phone and go from there. Similar complaints here. https://eu.community.samsung.com/t5/Galaxy-S9-S9/S9-Plus-crackling-stuttering-audio/td-p/441387/page...
I've also found YouTube video's with many of the same complaints.
I'll try reinstalling the app as nothing else seems to be working.
Nope, tried reinstalling app, still skipping, same as everyone else using other apps. music skips very annoying.
Update: After further testing it was revealed that the skipping problem went away after I removed the phone cover and also moved the phone very close to my 2018 model Onkyo reciever. I have to lean the phone up against the reciever or set it a foot or two away at the most, it will not stream correctly any further away than that.
It seems there is a very weak signal from the bluetooth radio on this phone.
By comparison using the same Onkyo reciever my wife's iphone using bluetooth can stream music from 40 feet away without any issues so I don't believe the issue is on the recieving end.
I just got this issue solved in my Galaxy S9+ by disabling the Adaptive Battery setting. Now my spotify music still plays even on Optimized and Medium Power Saving.
Settings - Device Care - Battery - Three dots options - Settings - Adaptive Battery (disable it).
I hope this helps someone else
