I'm going to change phone brands if you don't put ringtones back where it worked!

See Use tones and ringtones with your iPhone or iPad - Apple Support

Nobody here cares if you change phone brands. You have many to choose from and would recommend to find one that best meets your needs.

If you are looking for Support with an issue, then it would be best to describe what has changed for you. Apparently you are using an iPhone 7 Plus with iOS 15, so also include what version of iOS 15 you are using.

If you want to send Feedback to Apple, then that is done with the link below as they will not see your post here.

Otherwise it just appears to be a rant on a 10 year old vintage device that has served others quite well for a long time.

Hello~ It’s working fine for me. What seems to be the issue? Technical details please. Oh…just a word of advice…we are your fellow forum members and to be honest ultimatums have little affect here.

This is a user-to-user forum. Apple will not see your ultimatum.
