The code *#2663# on a Samsung Galaxy S23 (possible also S24, S25...) opens the firmware update menu for the touch screen panel (TSP/TSK firmware update). It allows you to check the software versions for the touch screen, touch keys, MCU/BINFW, and Wi-Fi. You can also attempt to update the touch screen firmware, which may help resolve issues with its responsiveness Caution: Use this code carefully. Updating the firmware can affect the display's functionality, and in rare cases (e.g., a failed update), it may cause issues like an unresponsive touch screen. If the screen is working fine, avoid updating unless recommended by a service center.
If you're experiencing display issues, you can also try other diagnostic codes like #0# for hardware tests or contact Samsung support.
