It is highly frustrating when a software update breaks a critical feature like your touchscreen, but this is a known software glitch that happens when a system update clashes with system caches or temporary files.

You can fix this issue by applying the troubleshooting steps below, ordered from quickest to most advanced. 

1. Perform a Force Restart

A temporary system freeze often happens immediately after an installation. A force restart clears the active memory without deleting your data. 

• Press and hold the Volume Down and Power (Side) buttons simultaneously.
• Keep holding both keys down for 10 to 15 seconds.
• Release them only when the Samsung logo appears on the screen.

2. Turn on Touch Sensitivity

Software updates can sometimes modify background display calibrations, reducing your screen's sensitivity to touch—especially if you have a tempered glass protector installed.

• Connect a wired USB computer mouse via an OTG adapter to navigate if your screen is completely unresponsive.
• Open the Settings app.
• Select the Display Menu.
• Scroll down and toggle on Touch Sensitivity.

3. Clear the System Cache Partition

Corrupted residual update files in the system cache partition are the most common culprit behind post-update touch failure. 

• Turn off your Samsung device completely.
• Connect the phone to a computer or your bundled USB earphones using a USB-C cable (this is required for newer Samsung models to enter recovery mode).
• Press and hold Volume Up and Power buttons together until the Samsung recovery screen appears.
• Use the volume keys to highlight Wipe Cache Partition and press the Power button to select it.
• Select Yes to confirm, then select Reboot System Now. 

4. Check for Patch Fixes or Boot into Safe Mode

Sometimes bugs affect specific features like the Multi Window feature on devices running One UI, or conflict with third-party launcher apps.

• Check for immediate hotfix updates under Settings > Software Update.
• If you suspect an app conflict, hold the power menu, long-press the onscreen Power Off icon, and tap Safe Mode. If touch works in Safe Mode, delete your most recently updated third-party apps.
