How to Fix Ghost Touch on Your Samsung Android Phone
Introduction: My Personal Ghost Touch Nightmare (and How I Fixed It)
Recently, my Samsung Galaxy S20 started acting strange, random apps opened, my screen swiped on its own, and sometimes it felt like I had a ghost in the phone! Initially, I thought removing my screen protector would help. However, that didn’t solve the issue. Then, I noticed it happened more often when charging with a third-party cable. Consequently, I switched back to the original Samsung charger and cable. Moreover, I discovered the secret code *#2663# to update touchscreen firmware. After doing that, the ghost touch nearly disappeared. Ultimately, I learned that a combination of proper accessories and firmware updates was the key. Now, I want to share this experience with you so you can fix your Samsung phone too without the frustration I went through.
What Is Ghost Touch?
Ghost touch, or “phantom touch,” is when your phone’s screen reacts as if it's being touched, even though you're not interacting with it. Consequently, the screen might swipe on its own, apps may open unexpectedly, or text might type itself. Understandably, this behavior feels frustrating and inconvenient, especially when you depend on your phone for important tasks.
Why Does Ghost Touch Happen?
A. Electrical Interference from Chargers or Cables
First, using low-quality or non-original chargers and cables often introduces electrical interference. As a result, the screen’s digitizer misinterprets this noise as touches. Many Samsung users notice this issue particularly when charging.
B. Screen Protector, Case, or Environmental Factors
Furthermore, an ill-fitting screen protector, tight phone case, or moisture and dust trapped at the edges can confuse the touchscreen sensors. For instance, in humid conditions, sweat can trick the screen into registering phantom inputs.
C. Software Bugs or Conflicting Background Apps
Moreover, glitches in Samsung’s One UI or certain third-party apps, including gesture controls or themes can cause the screen to behave erratically. Therefore, these apps might conflict with the native system and lead to ghost touches.
D. Firmware or Digitizer Problems
Additionally, touchscreen firmware that becomes outdated or corrupted can cause responsiveness issues. Fortunately, Samsung includes a hidden code (*#2663#) to update this firmware and potentially resolve the problem.
E. Physical Wear or Hardware Damage
Finally, physical damage such as impacts, pressure, or battery swelling can harm the digitizer. Consequently, even if the screen looks intact, internal issues may generate random touches.
How to Know If It’s a Software or Hardware Issue
Here’s a quick self-diagnosis:
- If ghost touch only occurs while charging, it’s likely a charger or cable problem.
- If it stops in Safe Mode, then a third-party app is likely the culprit.
- If updating with
*#2663#helps, the issue is likely firmware-related. - If the problem persists after a factory reset and stays in the same spot, it might be a hardware issue.
My Experience:
After replacing the charger and updating firmware, ghost touch on my phone nearly vanished. Consequently, I stopped worrying about random swipes or phantom taps.
Step-by-Step Fixes for Ghost Touch
1. Restart the Device
To begin, restart your phone. This clears temporary files and background glitches. Often, a simple reboot resolves ghost touch caused by minor software hiccups.
2. Use the Original Charger and Cable
Next, always use the original Samsung charger and cable. Ghost touch frequently appears with non-OEM accessories that don’t match the required voltage or amperage.
Tip: If ghost touch occurs mostly while charging, try wireless charging (if available). That’s how I identified the faulty accessory in my situation.
3. Remove or Replace the Screen Protector and Case
Then, check your screen protector and case. If they’re cracked, loose, or trapping moisture, remove or replace them. Often, this alone can stop the phantom touches.
4. Clean the Screen
Also, use a microfiber cloth slightly dampened with distilled water to clean the screen, focusing on the edges and corners. Dirt and oil build-up can contribute to ghost touch.
5. Boot into Safe Mode
Furthermore, booting into Safe Mode disables third-party apps. To do this:
- Press and hold the Power button
- Tap and hold “Power off” until “Safe Mode” appears
- Tap “Safe Mode” to reboot
If ghost touch stops, then uninstall recently installed apps one by one to find the source.
6. Update Touchscreen Firmware via *#2663#
Moreover, update your touchscreen firmware using this hidden code:
- Open the phone dialer
- Dial
*#2663# - Tap “TSP FW Update (General)”
- Wait for the update to complete, then reboot the device
My Experience:
This firmware update reduced ghost touch by about 80%, making it the most effective fix I found.
7. Check for Software Updates
Next, go to Settings > Software Update > Download and Install. Samsung regularly rolls out patches that address touchscreen issues.
8. Toggle Touch Sensitivity
In addition, go to Settings > Display and toggle “Touch Sensitivity” off and back on. This setting helps when using screen protectors.
9. Wipe Cache Partition
To further troubleshoot, wipe the cache partition via recovery mode:
- Turn off your phone
- Press Power + Volume Up (and Bixby, if available)
- Use volume buttons to select “Wipe Cache Partition”
- Confirm with the Power button and reboot
This removes temporary system files without affecting your personal data.
10. Perform a Factory Reset
If none of the above works, back up your data and perform a factory reset: Settings > General Management > Reset > Factory Data Reset
11. Replace the Screen or Visit a Repair Center
Finally, if the ghost touches persist especially in the same area, it’s time to replace the digitizer. Visit a Samsung-authorized repair center for a professional solution.
