You can install a Tencent mobile phone housekeeper to clean up the garbage. It has a special one-click optimization function, which speeds up the cleaning of your mobile phone with one click. But don't worry, it will only clean up the unnecessary data release space in your system and won't delete your important information. In addition, remember to use Tencent Mobile Manager to close the background program when using the mobile phone, which can also effectively improve the speed of the mobile phone.
