On the stock messaging app, I have a notification on the badge/icon/widget that won't go away. I've received messages over the last few months that were undeliverable, I cleared the notification on the bar at the top of my phone but the icon still shows the messages as unread. I've tried deleting the conversations from the senders of the undeliverable messages, I've tried clearing my cache & restarting the phone (which worked at first, but then as soon as I received a new text message the notifications came back), tried disabling the messaging app & re-enabling it, tried a hard reset (holding down the screen lock button & up volume for a few seconds), turned off notifications & turned back on. Nothing is working! Any help would be much appreciated!!
Try changing your default SMS app to Hangouts and see if you can find an unread or corrupt message (should be marked with a red "!") in that app. Delete any that you find and then change the default SMS app back to Messaging.
You can change the default SMS app by going to Settings > More > Default SMS app.
1. Tap the Application screen icon. 2. Find and tap Settings > Apps. 3. Swipe to the All tab. 4. Find and tap on the messaging app. 5. Tap Force stop > Clear data. 6. Restart the phone
