Why is my iPhone 16 camera control buzzing with electric shock?

Hello!

Neither bug nor feature. It’s a hardware issue. Take it to an Apple Store or Apple Authorized Service Provider (AASP) and have the issue diagnosed, before the issue gets worse:

• Genius Bar Reservations: Genius Bar Reservation and Apple Support Options
• Locate Apple Stores & AASP’s: Find a Reseller 
• iPhone Service & Repair: iPhone Repair and Service - Apple Support

Have a great day!
