Sony's mobile phone will display the screen when it is cold, and just cover it with your hand when it is hot. What is the reason?

After the display screen of the mobile phone appears, turn it off and put it in the refrigerator for 5- 10 minutes, and then turn it on after it is completely cooled. If the display screen disappears, it means that the display control chip on the motherboard of your mobile phone is soldered, which means that it will malfunction randomly with the temperature change of the mobile phone itself and the surrounding environment.

If the screen is still on after cooling, it may be the screen failure caused by the internal fragmentation of the LCD panel of the mobile phone.
