When receiving an incoming call the volume is low on my iPhone

Hi Jamoid,

Welcome to Apple Support Communities. We understand that you're having an issue with the volume of your ringer when you receive an incoming call. We'd like to help so you don't miss an important call.

Does this issue happen on all incoming call or only specific ones? Have you tried to change the ringtone to see if that changes the behavior? Use tones and ringtones with your iPhone, iPad, or iPod touch - Apple Support

Are you using the Attention Aware features on your iPhone? This can reduce the volume of your ringer if you are: Turn Attention Aware features on or off on your iPhone or iPad Pro - Apple Support

What are Attention Aware features?

Even if you don’t enroll in Face ID, the TrueDepth camera* intelligently activates to support Attention Aware features. With Attention Aware features, iPhone can check whether you’re paying attention to your device and automatically take action. For example,

* When you’re looking at your device, your display will not dim until you stop looking at your device.

* If you're looking at your device, it will lower the volume sound of your alerts.

We hope this helps. Have a great day!

You are very welcome, Jamoid. Please let us know if there's anything we can assist with in the future. Have a great day!
