On an iPhone, there is no built-in option to adjust the keyboard volume separately from the overall system volume. The click sound you hear when typing is controlled by the general system sound volume, which includes other interface sounds like lock/unlock noises and notification alerts. This means you can only mute or adjust the volume of keyboard clicks by either:
- Turning down the system volume,
- Using the mute switch (Silent Mode),
- Or disabling Keyboard Clicks entirely in Settings > Sounds & Haptics > Keyboard Feedback.
If you're looking for more granular control, such as adjusting just the keyboard volume without affecting other system sounds, you'd need to install a third-party keyboard app that includes custom volume controls. These apps can offer more personalization options, including sound volume, pitch, and even custom typing sounds.

The app developer may not have updated their software to ensure compatibility with the iOS version your device is currently running.
If you encounter any challenges with third-party applications, the best course of action is to directly contact the app developer for further assistance. Here's a brief guide on how to do it:
- Identify the app developer.
- Visit their website or app store listing.
- Look for their contact information or support channels.
- Clearly describe the issue you are facing.
- Provide any necessary information they may need.
- Follow their instructions and provide feedback.
- Be patient and follow up if needed.
By reaching out to the app developer, you increase your chances of receiving accurate and personalized support for the challenges you're experiencing. To contact an App developer --> How to contact an app developer - Apple Support
