Hello! First, make sure your iPhone is up to date:

1. Open Settings
2. Tap General > Software Update
3. Download and install any updates

If you've recently gotten your iPhone serviced, check if it was fixed using genuine parts: iPhone parts and service history - Apple Support.

The recommendation is usually to take your iPhone to get serviced by Apple or an Apple Authorised Service Provider: https://getsupport.apple.com

Have a great day!
