New phone. From 3 days ago. Each time I try to listen to voice mail messages on WhatsApp or Viber or play music on Sound Cloud app, the sound stop 1 or 2 minutes from the time the lock (black) screen turned on. Contacted WhatsApp and other apps. Said..it is a phone not app issue. Also check if any app sleep function is on and turn it off. I did every suggestion and solution mentioned on web. Nothing works!
