Samsung S20U camera focus issue often stems from misaligned OLED screen holes, which prevent the camera from centering properly. If your S20U
original-size OLED assembly has off-center holes and the camera can’t focus, here’s a quick fix.
First, check the top back of the screen for the small sponge pad that secures the camera module. This pad keeps the camera aligned with the screen’s
cutout. If it’s missing, the camera shifts, leading to focus failure.
Simply reattach the sponge pad to its original position, then reassemble the device and test the camera. This small component is critical for maintaining
proper camera alignment, and restoring it usually resolves the focus issue without further repairs.

This cost-effective fix helps avoid unnecessary part replacements and ensures your S20U’s camera works as intended.
