Keyboard sound and heptic is not working

Welcome Abhishek1902,

Sounds like they keyboard clicks and Haptic Touch isn't working on your iPhone. We'll do our best to help out with this.

We'd isolate the behavior further by trying to play some audio. You can use a variety of apps to test this, including the Music app. If you do not have any sound at all, see steps in: If you hear no sound or distorted sound from your iPhone, iPad, or iPod touch speaker - Apple Support

If you hear no sound or distorted sound from your iPhone, iPad, or iPod touch speaker

If you can't hear a person's voice clearly, hear crackling, hear static, or have issues with sound quality, learn what to do.

1. Check your sound settings

If your device has a Ring/Silent switch, move the switch forward—toward the device's display—so that orange isn't showing. If you're using an iPad, you can also swipe down from the top-right corner to view Control Center and make sure that Silent Mode is off. 

Open Settings > Focus > Do Not Disturb and make sure that Do Not Disturb is off.

2. Clean your receivers and speakers

Remove all screen protectors, films, or cases from your device. Check the speaker opening to see if it's blocked or dirty. On iPhone only, make sure that the receiver is not blocked or dirty. If necessary, clean the speaker or receiver opening with a small, soft-bristled brush. Make sure that the brush is clean and dry.

3. Check the sound on your device

Go to Settings > Sounds (or Settings > Sounds & Haptics), and drag the Ringer and Alerts slider back and forth a few times. If you don't hear any sound, or if your speaker button on the Ringer and Alerts slider is dimmed, your speaker might need service. Contact Apple Support for iPhone, iPad, or iPod touch.

4. Try making a call

If you hear sound, try making a call with your iPhone and turn on speakerphone. On iPad or iPod touch, make a FaceTime call. If you still can't hear, or hear static or crackling, then your network or reception could be the issue. Try to call again later, or from a different location.

FaceTime isn't available in all countries or regions.

In case it still doesn't work after these steps, then we would recommend bring it in for an inspection: iPhone Repair and Service

Get prepared for your visit: Get your iPhone, iPad, or iPod touch ready for service

Select your region and search nearby for locations: Find Locations

If you don't have any issues with sound using other apps, is your ring switch on the side of your iPhone enabled to ring or set to silent mode? When silent mode is enabled, you would not hear the keyboard clicks. What happens when you attempt to use Haptic Touch? See: Change 3D or Haptic Touch sensitivity on your iPhone - Apple Support
