If your Galaxy A36 starts tapping or scrolling on its own, you’re likely dealing with ghost touches. These random screen actions can make your phone almost unusable. The problem can be caused by a dirty screen, software bugs, or hardware interference, but most of the time, you can fix it at home.
Why Ghost Touch Happens on Galaxy A36
- Dirt, oil, or moisture on the display surface.
- Faulty screen protector or poorly fitted case.
- Software glitches or outdated firmware.
- Overheating or hardware-related touch issues.
- Using the phone while charging with an incompatible cable or adapter.
Clean the Screen and Remove Accessories.
Dirt, moisture, or static buildup can interfere with the touch sensor. Even tiny smudges can trigger false taps.
- Power off your Galaxy A36, and then wipe the screen using a soft, dry microfiber cloth.
- Remove any screen protector or case, and then restart the phone before testing again.
If the issue disappears, try replacing your screen protector with a high-quality, ultra-thin version designed for the A36.
Disconnect the Charger.
If ghost touches occur only while charging, the problem may be your charger or cable. Using non-Samsung accessories can send unstable electrical current to the touch panel.
- Unplug your charger, and then check if the issue stops immediately.
- Use the original Samsung charging adapter and cable, and then charge again to confirm.
Update the Software.
Outdated software may contain bugs that affect the touchscreen response. Updating ensures your Galaxy A36 runs the latest touch firmware.
- Open Settings, and then tap Software update.
- Tap Download and install, and then follow the prompts to complete the update.
Boot in Safe Mode.
Third-party apps can sometimes cause screen interference. Safe Mode lets you check if the issue is app-related.
- Press and hold the Side key until the Power menu appears, and then tap and hold Power off.
- Tap Safe Mode, and then wait for your phone to restart.
If the ghost touches disappear, uninstall recently downloaded apps one by one to find the cause.
Calibrate the Touchscreen.
Sometimes, the screen’s sensitivity can drift over time. Recalibrating helps the system relearn accurate touch response.
- Open Settings, and then tap Display.
- Tap Touch sensitivity, and then toggle it off and on again to refresh calibration.
You can also use Samsung Members’ diagnostics to test the touchscreen. Open Samsung Members, tap Support, and then select Phone diagnostics to check for touch irregularities.
Reset Settings.
If you’ve tried everything but the screen still acts up, a full settings reset can clear corrupted configurations without deleting personal data.
- Open Settings, and then tap General management.
- Tap Reset, and then select Reset all settings.
Your Galaxy A36 will reboot with default configurations while keeping your apps and files intact.
Ghost touches are annoying, but most cases are caused by simple issues like static buildup, a bad screen protector, or a buggy app. With these fixes, you can restore your touchscreen’s accuracy and stability.
FAQs
Why does my Galaxy A36 touch screen move on its own while charging?
It usually happens because of a low-quality or incompatible charging cable that sends unstable current to the screen’s digitizer. Always use the original Samsung charger.
Will a factory reset fix ghost touch?
Yes, in severe cases where software corruption is the cause. However, try the steps above first before performing a full factory reset.
Can overheating cause ghost touches?
Yes. When the phone overheats, it can affect the screen’s capacitive sensors. Let your phone cool down before using it again.
