Well the causes of this ghost touch vary, one of the most common cases is, buying a fake lcd, why buying a fake lcd can make the cellphone screen get ghost touch ? well that's because the fake lcd does not provide protection to its components when it is charged at a significant and continuous voltage position, so the longer it is charged while being used, of course the engine will get hotter, then the components in the lcd become damaged and are able to target the touch screen.
Therefore, there are a lot of people who use fake lcd and end up with ghost touch, well there are also several other causes why cellphones can be attacked by this ghost touch disease, well what are they ? let's take a good look at the explanation below:
1. Using Fake Chargers
Fake chargers are chargers that are made simply without calculating how many watts go into the charger and how many watts come out to charge the cellphone, well this charger also does not have a protection system in it so it is very prone to damage both the charger and the cellphone itself.
Now when this fake charger is always used, then usually the first component that will be affected is the flexible lcd, the flexible lcd will be disturbed because some of the flexible is damaged and unable to deliver the touch effect on the mainboard.
The effect is that the movement or touch will play around by itself, well at this stage the cellphone has begun to enter the ghost touch stage, and that's why the use of gas lighters containing low static electric lighters can make the ghost touch cellphone normal again even though this does not prove that the ghost touch disease disappears permanently.
2. Cell Phone is Often Crushed by the Body
If you always carry a cellphone while sleeping, then pay close attention to the location of your cellphone, because you may fall asleep while scrolling Reels/Shorts or tiktok or watching some films, the effect is that you accidentally overlap the cellphone you have on the mattress.
Now this overlapping effect is in fact very influential on the LCD on the cellphone, if the cellphone has a fingerprint LCD under the screen then the possibility of getting ghost touch disease will be greater, but some LCDs other than that are rarely affected by the ghost touch effect because of this overlapping effect.
3. Touch Screen IC Component is Damaged
Well this component you can get right in the screen or screen, well so behind the lcd screen precisely below near the flexible, you will see some ic material collected, well one of them is the touch screen ic, well most likely the touch screen ic is damaged.
The effect is that when no one plays it, the screen actually moves on its own without stopping.
4. Mainboard is Damaged
Well when using a fake charger for too long, then most likely the mainboard is also damaged, the effect of this mainboard damage is the ghost touch and some parts of the board are burnt.
But usually what will be damaged is the flexible plug, so even if you replace the lcd with the original version, the ghost touch effect will always be there because the flexible plug that connects the lcd to the damaged mainboard
Conclusion
Well maybe that's just 4 causes why the phone can move on its own, actually there are a lot of factors why the phone can move on its own, one of which I might not mention is, the fall of the phone into the water so that it affects the mainboard and flexible lcd itself, that's all from me, hopefully this information is useful for you.
