I have observed a fluctuation in screen brightness when utilizing the front-facing camera on the Samsung Galaxy S26 Ultra mobile device. This phenomenon consistently occurs upon activation of the front camera.
This usually happens because the phone is adjusting exposure and screen brightness together. The phone uses sensors + camera to brighten your face for selfies and to adjust screen brightness dynamically So when front cam opens it recalibrates lighting
