Any #iPhone users notice that the default keyboard sound sometimes suddenly gets louder? Very annoying, isn’t it?
The advice to get around this issue is to switch to #haptics so that you just feel a minute vibration when you make a key stroke.
I don’t find the haptics very satisfying after hearing the #keystroke click for years.
