How to fix ‘No notification sounds on iPhone when locked’

If iPad or iPhone notifications sound not working, meaning if your iPhone (or iPad) does not let you know when you receive an incoming text message (e.g., iMessage), check here how to fix this:

  1. Make sure that you do not have ‘Do Not Disturb‘ turned on. Check this by going to Settings > Do Not Disturb. Set this to ‘Off‘.
  2. Make sure that ‘Do Not Disturb‘ is not turned on for any particular contacts. To check this, launch the Messages app where you can see your messages.  Does any message have any moon sign? If there is, this means that you enabled ‘Do Not Disturb‘ for that contact. Do disable this, tab ‘Details‘ and turn off ‘Do Not Disturb‘.

  4. Your device has a mute switch (ring or silent). On your iPhone, this switch is located on the left side of your device, on your iPad, it is located on the right side of your iPad. Make sure that the mute button isn’t turned on by pushing the ‘Ring / Silent’ switch to the ‘Ring’ position.

To check, go to Settings > Bluetooth and check if any of your Bluetooth devices are connected and routing sound. If so, disconnect or unpair that Bluetooth device. Alternatively, if you’re not currently using any Bluetooth device, disconnect devices by swiping up Control Center or turn Bluetooth off by going to Settings > Bluetooth > Off.

  1. YAHOO! You are the only one who put this “wrist notification” thing in your article. I was baffled until you helped me find this obscure setting. Thank you so much!

  2. Omg… when the blue tooth is ooff, I get the messages. The only blue tooth is my car. I have no idea how to fix this, but at least I know what the problem is now. I’m even more frustrated because it says “not connected” as I’m not in the car!
