iPhone XR makes weird buzzing noise

I got rid of the nuisance buzzings.

I went to the Apple store. First backup your iPhone. Then go > settings>general >transfer or reset iPhone >reset network settings or reset all settings. I think he did reset network settings, yet he may have done the latter.

note: you will have to reinstall your Wi-Fi password once you do this. Good luck.

Remove the keyboard that you think is producing the annoying noise.

• Go to Settings > General > Keyboard.
• Tap Keyboards, then do any of the following: Remove a keyboard: Tap Edit, tap next to the keyboard you want to remove, tap Delete, then tap Done.

• Restart the device. That's it.

Add the keyboards you require.

• Go to Settings > General > Keyboard.
• Tap Keyboards, then do any of the following: Add a keyboard: Tap Add New Keyboard, then choose a keyboard from the list. Repeat to add more keyboards.

My iPhone XS started to do the same two days ago.

It really is discomforting.

Note to level 10 offering a fix:

One can only delete the Emoji keyboard and is not given the option to delete the remaining QWERTY, AZERTY, or QWERTZ keyboards.
