The volume up button is not clicking, every button not regestering

you can try if your volume buttons aren't working:

• Restart your phone: Restarting your phone can help restart your phone's software and background services.
• Check for physical damage: Look for dents or scratches that could be preventing the button from working.
• Clean the volume button: Sometimes a button gets stuck because it has collected dust and debris.
• Use soft keys: You can use soft keys to increase and decrease the volume.
• Create a sound widget: This allows you to adjust the volume on your home screen.
• Reset your phone: A full reset might work if your volume button stops working after an app download or a jailbreak attempt
