Hello, my mobile phone is Mi 1S Youth Edition. It was recently discovered that it always deletes messages automatically.

This may be due to data conflict when the old stable mobile phone leaves the factory.

Please don't worry. I suggest you back up your important data first, and then brush the whole package (I suggest you brush it to the latest development version) before using it to see if there are any problems you described.

Please brush the machine according to the brushing tutorial. The sixth method is line brushing:/thread-3104435-1-1.html.

At the same time, please download the line brush package suitable for your mobile phone:/topic-mirom.html.
