Common Camera Problems 

Modern smartphones usually have multiple cameras — front, rear, wide angle, telephoto, macro, depth sensor — which means more parts that can go wrong. Here are the issues we see most often:

1. Camera app shows black screen

2. Shaking, buzzing, or blurry image

3. Camera will not focus

4. Front camera not working

5. Flash not working or stuck on

Common Face ID Problems 

Face ID is far more complex than most people realize. On iPhones, the Face ID system includes several components: infrared camera, flood illuminator, and dot projector. If any one of them fails, Face ID stops working.

Here are signs of Face ID hardware failure:

1. Face ID not available message

2. Face ID not working after screen repair

3. Cannot set up Face ID

​

What Causes Camera and Face ID Failure?

• Drops or impact damage

• Liquid exposure

• Incorrect screen or battery replacement

• Flex cable damage during other repairs

• Manufacturing defects or aging sensors

• Faults in the logic board or connectors

Face ID in particular is very fragile. Once damaged, it cannot be replaced like a simple camera. Repairs often involve micro soldering and sensor calibration.

​

What You Should Do First?

Before bringing your phone in, try these steps:

• Restart the phone

• Update to the latest software version

• Test in other apps (some third party apps use different camera APIs)

• Try setting up Face ID again in settings

If none of that works, you are likely dealing with a hardware problem.
