Spotify wont stream over data connection

[Kingfry7]

Spotify wont play music over data connection. Wifi works fine. I've went into the settings and made sure the streaming setting was set to automatic. I've deleted the cache and i've also deleted and reinstalled the app and the problem persists. my data connection is strong and my other streaming services work fine over data. The songs will only play for a second or two before it stops. I have a Galaxy s7 edge. i pay money for a service that doesnt do it's most important function. I think i might cancel my subscription. I'd rather pay for google or apple music and actually be able to listen to music

From this post:

If you are using a Samsung device which has been updated (or running) Android 6.x Marshmallow it appears that they have introduced an agressive power saving option which is closing Spotify or stopping it accessing data when the application is sent to the background or the screen display turned off. The following are common symptoms caused by this:

Symptoms:

• Next song in an album/playlist is not played
• Lock Screen control vanishing
• Spotify notification disappears
• Tracks marked for offline listening fail to download
• Notifications for new followers, albums etc have not been coming up

Resolution:

If you are using a Samsung device and experiencing any of these symptoms please disable the Power Saver settings as follows: 

Settings > Battery > Power Saving Mode> In the Power Saving Mode settings disable the "Restrict background data" setting

Kudos to @Cerda45 for the tip here

If it's still not working after doing the above then disable Power Saving Mode entirely:

Settings > Battery > Power Saving Mode

Settings > Battery > Detail > Spotify >Turned off
