While wiping the screen, make sure you don't get moisture into any openings.

Apple recommends avoiding window or household cleaners, as well as cleaners containing abrasives or hydrogen peroxide, as these could erode the oil-resistant coating Apple puts on your iPhone's screen.

2. Take Off Your Screen Protector

Screen protectors are thin layers of glass or plastic that you can attach to the iPhone's touchscreen to protect it from scratching or cracking. While they're often useful, they can disrupt how the touchscreen operates if they're of poor quality.

You should, therefore, try removing your screen protector to see if it fixes ghost touch problems. Remove your iPhone's screen protector very carefully and slowly. Start at one corner, then gradually peel the protector off the iPhone's screen.

If the protector has been cracked or damaged at all, it might be safer to take your phone to a suitably qualified repair shop (or to Apple) to ensure you don't cut yourself on the cracked glass.

You should also consider contacting the manufacturer of the screen protector. The manufacturer might be better placed to recommend the best method for removing the protector and may be able to refund you if the screen protector caused your iPhone's ghost touch problems.

Don't forget to clean the screen again after removing any screen protectors.

3. Remove Your iPhone's Case

A slightly twisted screen is another possible cause of ghost touch issues on an iPhone. If your iPhone has such an issue with its screen, you might be able to solve the problem by removing any hard case you're using. Sometimes, a hard case may twist the screen, and these cases can also get twisted after an accidental drop.

As such, it's worth trying to remove the hard case if your iPhone has one.

4. Maintain Good Charging Habits

Do you often put off charging your iPhone until the battery percentage drops to single digits? Or perhaps you frequently let the battery die, and your iPhone has no choice but to shut itself down?

Poor charging habits can also cause ghost touch issues on the iPhone. Therefore, it's best to plug in your iPhone to charge before the battery drops lower than 20 percent. Consider adopting the smartphone charging habits we recommend.

5. Keep Your iPhone Away From Cold Surfaces

Although Apple states that an iPhone works fine in ambient temperatures between zero to 95 degrees Fahrenheit, it's still best to avoid leaving it on cold surfaces for extended periods.

For example, I used to place my iPhone on the tiled floor next to my bed when I went to sleep. As the air-conditioning filled up the room throughout the night, the tiled floor naturally got colder.

Unaware, I did this for almost a week, and my iPhone started to have ghost touch issues. Once I left my iPhone on my wooden desk instead, the ghost touch problem stopped, and my iPhone worked normally again.

6. Restart Your iPhone

It's always a good idea to restart your iPhone whenever it has a problem. This also applies to ghost touch issues, since it's possible that clearing your iPhone's short-term memory by restarting it could fix any glitch causing the screen to play up.

Similar to restarting your iPhone but noticeably more drastic, you could force restart (or soft reset) your iPhone. You can do this if your iPhone's ghost touch problem is so severe that you can't even turn it off properly.

7. Update iOS

If ghost touch is still a problem, you should update your iPhone. This is worth doing because ghost touch could be caused by a software bug that Apple has fixed in a recent update.

To update your iPhone, go to Settings > General > Software Update. Tap Update Now if a newer version is available.

If ghost touch only happens when you're using a third-party app, you should update that particular iPhone app as well to get the latest bug fixes for it.

8. Perform a Factory Reset

If restarts and software updates don't stop your iPhone's ghost touch problem, you should perform a factory reset on your iPhone. This is a good way of removing any underlying software issues that might cause ghost touch.
