Of course it works. It can clean up the cache garbage of the mobile phone and improve the speed of the mobile phone. I don't know what's in your mobile phone. I use Tencent mobile phone housekeeper, known as the mobile phone acceleration artifact. It has a special one-button acceleration function, which can make your mobile phone accelerate with one button. But don't worry, it will only clean up the unnecessary data release space in your system and won't delete your important information. And its acceleration rocket, the average acceleration is 35% of the mobile phone. Very easy to use.
