Sound turns off when screen goes black

[Android Central Question]

Bought phone july 2018 and have since listened to music etc via headset. Now, suddenly the music/sound stopes after between 9-20 minutes and the screen is dark. Before that was ok and the sound continued, but not now.
I have not changed a single thing on the phone and I have tried to find the solution in the manual but so far I haven't.

Welcome to Android Central! Which phone, and which app are you using to listen to music? Any power-saving modes turned on? Is Restrict Background Data turned on for the app?

Hi thx.
It is a Samsung Galaxy S9plus
I listen to music online via a webpage or sometimes downloaded pods, sometimes radio, it varies.
No , restricted bakground data is not turned on and powersaving has been on since the very first day I bought it. As I mentioned, I have not changed a single thing....I was happy as I was...

Did this coincide with a system update?

 

[GalaxyS9Plus]

Not that I am aware...
Do you think that if so, the update would have changed something? If I only knew what then...

 

[B. Diddy]

The Pie update rolled out to the S9 line fairly recently, and as usual, it came with a number of apparent bugs (as well as a lot of major UI changes and new features that might be confusing to some).

Just as a test, turn off power-saving and see if the problem persists.

ok, I will try that again.... Thx

No, it did not change anything. Really disappointing as I use the phone for this purpose about 80% of the time. Can I undo the new update?

Undoing an update means using Odin to flash the previous firmware: http://forums.androidcentral.com/am...w-flash-stock-rom-via-odin-new-interface.html. Unfortunately, once on the old firmware, the phone will then prompt you to install the update, and probably won't let you refuse after a certain amount of time unless you root the phone and disable the system updater.

If you use an app that is definitely supposed to stay on while the phone is asleep (like Google Play Music or YouTube Music), does the playback still stop on its own? (The browser usually doesn't stay awake.)

really? well, it is not for me then... You tube stays on, even the screen. If I play musicfrom a radiostation or so ithe screen goes dark and after approx. 9 munites the music stops.Now, I downloaded Firefox last night and it seems to work there!The same radiostation never stopped in Firefox! Just when I had Chrome where I wanted it...never mind, guess I have to be happy now!

Install Keep Screen On from the playstore and run it when using your timing out app.

Hi methodman89, I am not sure as I don't really need or want my screen on, I just want to listen to things...or will thhatsort of keep the screen on but dark?
