Mute iPhone Imagine this: You’ve double-checked your phone to make sure the ringer is on and you’ve turned the volume all the way up because you’re waiting for an important phone call, and when the phone rings, you’re going to hear it. Minutes go by and you glance at your iPhone, only to find out you’ve missed that important call! Totally irritating! So, what could be the reason why it happened so? 📱 Most of the time, the reason an iPhone doesn’t ring for incoming calls is that the user has accidentally turned on the Do Not Disturb feature in Settings. 📎 How to know if you turned on the Do Not Disturb feature: 🖇 In the upper right hand corner of your iPhone, just to the left of the battery icon, you’ll see a small moon icon there. 📎 How to turn off Do Not Disturb feature: 🖇 Swipe up from the bottom of your phone to reveal Command Center. Tap the moon icon to turn Do Not Disturb on or off. That’s it! As easy as 1 2 3. 📱 If you disabled Do Not Disturb feature and your iPhone isn't still ringing, there’s a good chance you may have a hardware problem. 📎 Often times, when gunk or liquid gets into one of the ports (like the headphone jack or lightning / dock connector), your iPhone thinks there’s something plugged into it, when in fact there isn’t. Do Not Disturb feature is one of those great features that comes in handy if you know how to use it, but it can be really frustrating if you don’t. So be careful and be much aware of its use.
