Tools/raw materials:

Huawei P40

EMUI 10.0

Set 8.0. 1 1.

1. First, open Settings on your phone.

2. Select "Apply and Notify".

3. After jumping out of the next interface, select the first option "Application Management", click the arrow at the back to open it, and the software downloaded from the mobile phone will be found here.

Now let's take a software as an example. Now what is displayed here is "186M", which is the memory occupied by this APP.

5. After clicking in, you will see the description of authorization authority and storage memory, and click the option behind.

6. There are two contents: "Delete data" and "Clear cache". "Clear data" means that the software has created memory in the mobile phone, occupying memory space; "Empty the cache" is the garbage generated by the running of this software. Since you want to delete it completely, choose both.

7. After selecting "Delete Data", an interface will pop up to confirm whether to delete it again, because selecting "Delete Data" means completely deleting all data, including the logged-in account (the account will not be deleted), and you need to log in again manually.

8. When you return later, you can see that the cache has changed to 0.
