2. Galaxy device touch issue: ● Kindly check if the device's touch screen is physically damaged: The phone touch screen could stop working due to physical damage.
● Physical damage: The touch screen is broken or damaged. High temperature, cold, moisture, magnets, and static electricity can all damage the touchscreen of Android phones. If your screen is damaged, you need to carry your device with its ''original accessories'' to the ''Samsung authorized service centre''. If your screen is not damaged, Restart the phone by pressing the Power button and then tap on Restart. Note: If you use the Fingerprint security feature, the phone will require your backup password to unlock after rebooting.
● Review touchscreen tips and tricks. Certain factors may affect how well the touchscreen on your device performs. Please keep the following in mind when using the touchscreen:
•If a third-party screen protector or accessory is attached, the touchscreen may not work properly. In particular, it may not work well if there is dust or air under the protector, if two or more protective films are attached to the screen, or if the protective film is peeling near the edge of the screen. Remove the screen protector or film if it is peeling or has debris underneath it. If you are keeping the screen protector or film, you can enable the touch sensitivity option to help with taps and touches. Open Settings, then tap Display, and then tap the switch next to Touch sensitivity.
•The touchscreen may not work properly if you wear gloves, have dust on your finger, or touch the screen with fingernails or a ballpoint pen. It may also not work if a conductive object, such as a coin or key, is close to the screen.
•If the screen is wet, the touch sensor may not work properly. Even for waterproof models, some touch functions may not work if the product is used in water. Gently wipe the front and back of your device using a lint-free, soft microfiber cleaning cloth or a camera lens cleaning cloth. Do not apply too much pressure when cleaning the device.
•If you are having issues with the S Pen, refer to our S Pen troubleshooting.
● Check your charger. If your charger is damaged, it may not supply power to your device, which may cause the touch screen to malfunction. In this case, use a different, undamaged charger to prevent this issue. It’s also a good idea to avoid using the touchscreen when the device is charging.
Note: To complete Steps 4 through 6, you can try connecting your device to a computer or monitor. This will allow you to navigate the device even if the touchscreen isn’t working.
● Disable gestures: When using the full screen gesture function, touch input may not be possible because the touch is recognized as a gesture. To stop this from happening, disable the full screen gesture function. Open Settings, tap Display and then tap Navigation bar. Tap Buttons to disable full screen gestures.
● Disable Touch sensitivity: If the Touch sensitivity setting is turned on when no protective film is used, the touchscreen may respond too sensitively and therefore malfunction. To disable the Touch sensitivity feature, navigate to Settings, tap Display, and then tap the switch next to Touch sensitivity to turn it off.
● Perform a factory data reset. Resetting your device to factory defaults should only be used as a last resort and after trying the previous steps. A factory data reset will remove all data and content from your device. Before performing a factory reset, be sure to back up your personal data, so you don't lose it all.
Path: Navigate to and open Settings, then tap General management, and then tap Reset. Tap Factory data reset, then swipe to and tap Reset, and then tap Delete all. Enter your Samsung account credentials to complete the reset; your device will reset, and you will need to perform the initial setup process.
