My Iphone 4S doesn't make notification noises?

All my settings are turned on for my phone to make noise whe I receive notifications. However, when I do receive any notification from any app it appears on my lock screen but doesn't light up my screen or make a noise, what could possibly be wrong?

Go to Settings-> General -> Reset -> Reset All Settings
And redo your personal settings choices, it will work surely

I would check Setting > Notification Center and make sure thateach of the notifications are turned on. A complete reset is always possible but rather drastic. If you have just done a IOS upgrade, it is possible that the defaults didn't make it when the upgrade was done.

  • Why doesn't my right headphone doesn't make sound? I have the iPhone 7 EarPods (not the Bluetooth ones ) They were working just fine until one day I realized that there was no sound coming out of the right side. I already cleaned it but doesn't work. How do I fix this?
  • Why doesn't it make a noise when I get a Facebook notification on iPhone? There's a noise when I get a message but not when I get a notification like when someone writes on my wall or something. I have it set to but it only does the noise if I upload a picture or something? Is anyone else's iPhone like this?
  • Why does my PC make clicking/popping noises? It's not the speakers themselves, as it happens with headphones too. It seems like when the PC is heavily taxed, any audio playback will sometimes contain sporadic pop noises. It happens from a midi playback program, from iTunes, from Youtube videos - anything. I definitely notice an increase while I'm recording something. What can I do?
  • Why does my iPhone not make any noises? My iPhone does not play sounds through the speaker when I get the call. I also can't hear people when speaking to them in a call and it does not play music through the headset. How can I fix this?
