Hi andras17,
Welcome to Apple Support Communities. To help troubleshoot haptic feedback further, our recommendation is to update the software on your iPhone to iOS 16.6.1. This is the latest update that's available and may help as it provides software improvements. If needed, here are the steps on how to update the software on your iPhone:
Update your iPhone or iPad wirelessly
1. Back up your device using iCloud or your computer.
2. Plug your device into power and connect to the internet with Wi-Fi.
3. Go to Settings > General, then tap Software Update.
4. If you see more than one software update option available, choose the one that you want to install.
5. Tap Install Now. If you see Download and Install instead, tap it to download the update, enter your passcode, then tap Install Now. If you don't know your passcode, learn what to do.
This information is outlined in this article: Update your iPhone or iPad - Apple Support
In addition, you'll want to make sure that "System Haptics" is turned on. This is an additional step that can help. To verify that please open the Settings app > Sounds & Haptic > System Haptics.
Following these steps may help and we look forward to hearing back from you with an update.
Best regards.
