Question:

“What are the expert-recommended steps to resolve the ‘ghost touch’ issue on Samsung phones, where the device seems to autonomously open apps and input text? My phone has been exhibiting this behavior for several weeks. Previously, I managed to stop it, but I can’t recall the solution. Currently, the issue only ceases while the phone is charging, which is not a viable long-term fix. Could you provide guidance on how to permanently rectify this problem?”

Answer:

The ‘ghost touch’ phenomenon on Samsung phones can be a source of frustration for users. This issue, characterized by the phone registering inputs and executing actions without any user interaction, can significantly hinder the device’s usability. If you’re grappling with this problem, rest assured that there are several expert-recommended steps you can take to resolve it.

Your Samsung phone comes with a touch sensitivity feature designed to enhance screen responsiveness, especially when using a screen protector. However, this heightened sensitivity can sometimes lead to ghost touch issues. Navigate to your phone’s display settings and toggle off the touch sensitivity option. Additionally, accidental touch protection is available in One UI to prevent unintended interactions when the phone is in your pocket or bag. Enabling this feature may mitigate the ghost touch problem.

2. Update Touchscreen Firmware and Software

Outdated firmware can often be the culprit behind ghost touch issues. To update the touchscreen firmware, open the Phone app and dial *#2663#. Tap on ‘TPS FW update (General)’ and wait for the phone to reboot. It’s also crucial to install any pending software updates for your phone, as these can contain important fixes and improvements.

3. Allow Your Phone to Cool Down

Overheating can affect your phone’s performance and lead to various issues, including ghost touch. If your phone is hot to the touch, allow it to cool down before using it again.

4. Scan for Malware

Malicious software can interfere with your phone’s normal operations. Use a trusted antivirus app to scan your phone for malware. If any threats are detected, follow the recommended steps to remove them.

5. Clean the Display and Remove Screen Protectors

A clean display is essential for proper touchscreen functionality. Dirt, dust, or an improperly applied screen protector can cause ghost touch issues. Remove any screen protector and clean the display thoroughly.

6. Change the Charger

A faulty charger can cause electrical interference that leads to ghost touch. If the issue occurs only while charging, try using a different charger and cable to see if the problem persists.

7. Replace the Phone’s Broken Screen

If your phone’s screen is damaged, it may need to be replaced. A broken screen can cause persistent ghost touch issues that won’t be resolved through software fixes.

In conclusion, the ghost touch issue on Samsung phones can usually be addressed through a combination of settings adjustments, software updates, and physical maintenance. If these steps do not resolve the problem, it may be necessary to consult with a professional technician or consider a warranty service if applicable. Remember, regular device care and maintenance are key to ensuring a smooth and responsive touchscreen experience.
