I'm not sure what to do but when I receive a text message, I receive the notification. But the message sound notifies me 10-15 seconds later. Even if I've already read replied to the message. I've already cleared the messages cache and data and I've force stopped it. I even restarted my phone. But the issue still persists
Ok try this. Go to settings/apps then select that app and open it. Go to the battery section and open that and choose the radio button "Unrestricted". See if that helps.
