What should I do if the old machine I bought always shows out of sync?

The endowment machine is not necessarily a functional machine. Nowadays, mobile phones are getting cheaper and cheaper, and most of the problems are solved with low-grade intelligent functions.

The old man-machine does have some defects. If it is designed for the elderly, you can buy a smart phone and download and install Yinmei's desktop for the elderly in the smart phone. Compared with the old man-machine, it has many more functions, and it can also input information by voice and read short messages. That's good. I recommend it to you.
