Background technique

With the development of technology, the functions of mobile phones are becoming more and more powerful.

At present, most mobile phones are equipped with high-resolution cameras, and some mobile phones also have an original image engine, through which several high-resolution photos are synthesized into a high-definition original image, although a high-resolution camera can capture Very clear photos, however, this kind of photos also take up a lot of space, which makes some flash memory cards (such as TF cards) due to their own hardware limitations, the writing speed is much lower than the photo requirements, so when using high-pixel When the camera takes pictures (such as continuous shooting), it is prone to stuttering, or even data backlogs that cause the system to crash and crash. In addition, the theoretical value of the long-term evolution (LTE, Long Term Evolution) download rate will reach 20 megabits per second, and it will be higher in the future. Usually, the mobile phone will download data to its flash memory card, because the download speed determines the write rate. Speed, which also makes it easy to get stuck when downloading data to the above-mentioned flash memory card, or even cause the system to crash due to a backlog of data.

At present, there is no relevant solution to prevent the problem of the mobile phone freezing and crashing due to the slow reading and writing speed of the flash memory card.
