Why does my mobile phone sometimes show that it is loading as soon as I open the text message, and it can't be opened all the time, so I have to restart it to recover?

It takes time for mobile phones to read SMS data. Before the phone has finished reading the data, it will show that it is loading. There are several possibilities for slow reading. There are too many short messages to load data so slowly, two kinds; The cpu of mobile phone is too low to process data slowly, third; There is something wrong with the cup, which will lead to unreadable or quite slow, four kinds; There is too much data running in the mobile phone or too much stuff in the memory. I suggest you clean up the garbage and text messages in your mobile phone to see if it is fast. If it still doesn't work, it means there is something wrong with your mobile phone cpu. Remember to give points. thank you
