My phone was on DND ( Do not Disturb). I called a friend and after the conversation, within a minute he called me back and my phone started to ring despite being on DND. Not just this, after again having a conversation and ending the call, he called again within 2-3 minutes and now there was no call screen or any popup showing up on the screen. It was by chance that I unlocked my phone and checked the notification panel and saw the call.
Don’t know weather this I is a glitch or some settings issue. Please help me out with this.
