On the Galaxy Z Fold6, the inner big display uses an Under Display Camera (UDC), which is designed to blend into the screen. If you notice that the camera cutout has become more visible in the last few days, don’t worry, this is usually not a fault. A few things can make it more noticeable:
Brightness / Background color – On light backgrounds (white/grey), the UDC can appear more visible.
Screen protector / Dust – If dust or a screen protector edge is near the UDC, it can make it stand out.
Software / Display settings – Sometimes after an update or display mode change, the blending effect may appear different.
What you can try:
1. Clean the main screen gently with a soft microfiber cloth.
2. Check if you are using any third-party screen protector that might interfere.
3. Restart your device once.
4. Make sure your phone is updated to the latest software (Settings > Software update).
If the UDC still looks unusually visible all the time, I recommend running a quick test in the Samsung Members app → Support → Phone diagnostics → Camera test.
If it continues, please visit the nearest Samsung Service Center for a proper checkup.
