I see you're having some trouble with your ringtones. I'd be happy to help..
Something I wanted to take a moment to clarify is how you're selecting these ringtones. Are you going to Settings > Sounds & Haptics and selecting what you want from there, or are you setting up ringtones for specific contacts? If you're doing both; great. If you're only doing one, let's make sure they're both set up. Here's how, just in case:
Use tones on your iPhone, iPad, or iPod touch - Apple SupportChange your ringtone
- On your iOS device, go to Settings > Sounds & Haptics.
- Tap the sound that you want to change. You can change your Ringtone, Text Tone, New Mail sound, Calendar Alerts, and more.
- Tap on the name of a ringtone or alert tone to hear it play and set it as the new sound.
You can also set a Ringtone or Text Tone for a specific contact. Find the person in Contacts, then tap Edit in the upper-right corner. Tap Ringtone or Text Tone, then choose a new sound.
Once you have them both configured, restart your iPhone like this:
Restart your iPhone, iPad, or iPod touch - Apple SupportHow to restart
- Press and hold the Top (or Side) button until the slider appears.1
- Drag the slider to turn your device completely off.2
- After the device turns off, press and hold the Top (or Side) button again until you see the Apple logo.
- Your iOS device has a Top button or a Side button. Either way, they do the same thing.
- With iOS 11 or later, you can turn off your device by going to Settings > General> Shut Down.
Afterwards, test the ringtones and see if there's any change. It'd also be helpful if you let me know how these ringtones were obtained. Did you download them through the iTunes Store, or were they downloaded through a third-party source? I'll take it from there.
