The screen did not respond in the cold
There were many reasons why the screen did not respond in a cold environment. Taking the iPhone X as an example, its LCD touch screen would temporarily malfunction at low temperatures, and the touch screen would have difficulty recognizing the user's finger swipes and other gestures. This meant that the screen was sensitive to temperature changes, and low temperatures could affect the normal working mechanism of the screen. From a technical point of view, the screen of an electronic device depended on components such as the internal circuit system. The low temperature environment may affect the performance of the circuit, such as causing changes in the parameters of the electronic components, reducing the stability of the circuit connection, etc., which may cause the screen to fail to respond to operational instructions. In addition, from the perspective of device construction and material characteristics, different screen materials may have different performance at low temperatures. For example, some screen manufacturing materials may shrink and become brittle at low temperatures, which may also affect the touch function of the screen. In order to avoid the screen not responding in the cold, you can minimize the exposure time of the electronic device in the cold environment, or take measures to keep the device warm (if feasible). If the screen is already unresponsive, you can try moving the device to a warm environment and wait for the temperature to rise before checking to see if the screen is back to normal. However, the specific solution still needed to be determined according to the type of equipment, structure, and the specific situation of the fault. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The phone appeared when reading a novel, from the edge of the black screen to the middle of the black screen
This situation was often referred to as the "reading mode", which was a protection mechanism of the novel reader to prevent the user from losing the device's response due to accidental operation while reading. When the user entered reading mode, the phone would pause all running programs and lock the screen in one place to ensure that the user could not slide the screen, click on the elements on the screen, or let the phone fall from a high place. If the user accidentally triggered the reading mode while reading a novel, the phone might turn black from the edge to the middle. This was because in reading mode, the phone would lock the screen in one place to prevent the user from performing any interfering operations. If the user tried to swipe the screen or click on an element on the screen while reading, the screen might unlock and trigger a black screen. If the user finds that the phone has a black screen while reading a novel, they can try to turn off the reader or reopen the reader to cancel the reading mode. In addition, you can also try to place the phone on a stable desktop or adjust the brightness and contrast of the screen to avoid similar problems.
Why is there no sound when the phone is red and the screen is black?
The reason why there was no sound when the screen turned black was probably because the phone had entered energy-saving mode when the screen turned black. The power-saving mode would limit the phone's power consumption in order to extend the phone's lifespan. The phone wouldn't make any sound when the screen went black because the sound sensor needed light to detect sound. If the phone entered the power-saving mode, the black screen might silently suggest to try to restart the phone or switch back to normal mode.
There are black lines on the screen when the phone takes pictures
If a black line appeared on the screen when the phone was taking pictures, there could be several reasons: ** 1.
