Over the past few weeks, my Samsung phone has started developing a noticeable screen issue. There is a faint but visible flickering across the display, especially when the brightness is low or adaptive brightness is active. At times, parts of the screen appear to dim unevenly, creating a patchy effect. Additionally, I've experienced random touch unresponsiveness, requiring me to lock and unlock the device to regain normal operation.

I've already tried basic troubleshooting steps — including restarting the device, clearing the cache partition, and running a full diagnostics test through Samsung Members — but the issue persists. It's particularly frustrating because the device is otherwise functioning perfectly and has not suffered any drops, water exposure, or physical damage.
