Part 1: What Causes Huawei Mate 20 Lite Ghost Screen?
Having an idea of what might be causing Huawei Mate 20 Lite ghost screen is important for effective troubleshooting. There could be many factors leading to this problem. Here are some potential reasons:
Dirty Screen
If the screen is dirty, the touch sensor may misinterpret the inputs, which may cause ghost screen issues. Over time, residue from dust and oils build up, causing unintended touches or areas on the screen that do not register.
Defective Charging Cable and Adapter
Electrical issues that influence the functioning of the screen can stem from utilizing a faulty charging cable or connector. Touch screen issues may also occur due to irregular power supply or voltage spikes, causing ghost touches and unresponsiveness.
A Worn Screen Protector
An old or improperly put on screen protector can cause touch sensitivity issues. With time, scratches, bubbles, and wear and tear can affect the ability to read the touch and this is how ghost touches occur.
Misbehaving Third-Party Apps
Some third-party apps make the screen not respond due to system overload or conflict with the phone software. There are some apps which run background processes and keep interrupting with normal functionality of touch screen, causing ghost touches.
An Outdated OS
So, if you are on an outdated operating system, this can create compatibility issues or bugs that affect how your screen performs. Since software updates usually contain bug-fixes, missing from it may cause your device to remain vulnerable to bugs such as ghost screen.
Electromagnetic Interference
Nearby electronic devices may cause electromagnetic interference that disrupts touch screen functionality. Microwave ovens, wireless routers, or even other phones can send out signals that disrupt the screen’s touch response.
Hardware Issues
If there are hardware issues like a damaged digitizer or some internal component then you might end up having persistent ghost screen issue. Drops or moisture exposure can cause physical damage that keeps the screen from registering touches properly, resulting in ghost touches.

Having dirt, oils and other residues on your hands or the screen can cause accidental touches. Softly rub the screen with a microfiber cloth to remove dirt or smudge. Make sure your hands are clean and dry before using the device, so that you don’t confuse it with the touch sensors.
✨Remove Any Screen Protector
A damaged or worn screen protector can create touch sensitivity issues. If you are using a screen protector, remove it to see whether it is the cause of the ghost screen issue. If the problem gets fixed, you may want to replace it with a new protector.
✨Take Off the Phone Case
A very thick or poorly constructed phone case can also sometimes cause accidental presses on the screen – if it pushes up against the contact points for the touch sensors.
