Why is my mobile phone short message sent so slowly?

The fundamental reason is that the background running space of the system is filled with trivial junk files, which leads to the slow running of the system and the phenomenon of sending SMS cards. Giving some advice to the landlord can solve the landlord's problem perfectly.

1. Back up all the phone books and useful files in the machine to PC or memory card, and then enter *#7370# in standby mode, that is, the format command, which can solve the problem immediately, but the same problem will appear after a period of time, because junk files will always be generated;

2. Go to Nokia's after-sales service department and brush a system with version 4.0642.5.05 to solve this problem. I use this method, and it is still very smooth.

3, to develop a good habit of using mobile phones, especially smart phones, when you quit the menu and other operations, you should completely quit. Don't press the hang-up button directly, so sometimes the program is still executing in the background. If the landlord likes surfing the internet, remember to know the cookies of the mobile phone regularly.

After the answer, the above are the solutions and my suggestions. I hope the landlord's problem can be solved as soon as possible. It doesn't matter if it really doesn't work.
