I have y notifications on for facebook and snapchat but my phone won't tell alert me with a badge or a sound. I have to open facebook or snapchat to see if anything is new. I got this iphone new today so it should be working

Added (1). I have it on in notifications with sound on and lock screen on

To to settings>notifications and make sure that the alerts are turned on for FB and whatever else you want notifications for. You can pick banner style or pop up.

Setting>notifications>facebook must be on and make sure you allow badge icon sound and view in lock screen

  • Why won't my Iphone alert me when i get a text? My phone, iphone 4s, always used to show me a banner whenever i get a text. It just randomly stopped. I checked in notifications about a million times and its set to show me a banner. I haven't dropped it or done anything that would have broken my phone. I would just really like to know how to fix this without taking it to an apple store.
  • Why won't read messages disappear from my notifications tab? I've had the iPhone 6s for exactly two weeks now, and I'm continuously having this problem. One or two random texts messages a week won't disappear from my notifications tab, even after I read it. I click remove, it stays. I slide to the left and click the x or reply, and it's still there. After I turn the phone off and on it goes away, but I don't want to have to keep doing that. Any suggestions? Is this happening to anyone else?
