Notifications sound low

Hello karthiban176,

If you have checked your volume from Settings > Sounds & Haptics as mentioned in Adjust the volume on iPhone - Apple Support and this continues, check Attention Aware Features next. This feature can lower volume if you are looking at your iPhone. You can disable that from Settings > Face ID & Passcode. Check out Turn Attention Aware features on or off on your iPhone or iPad Pro - Apple Support.

Take care.

Hi karthiban176,

Thanks for contacting Apple Support Communities!

We understand that your notifications aren't as loud as you'd like. Does it make a difference if you adjust your iPhone volume? This resource will show you how: Adjust the volume on iPhone - Apple Support

If you're still unable to hear your alerts as you'd expect, check out the additional troubleshooting steps outlined here to help you to isolate this behavior further: If you hear no sound or distorted sound from your iPhone, iPad, or iPod touch speaker - Apple Support

We hope this helps.

Cheers!

There is no way to fix it. Don't waste your time touching things. It is the way it is and I hope Apple does something about it because I have been missing whatsapps and gmail notifications since March when I got this phone.
