Aauto, where can I set up to delete spam messages faster?

How does Aauto clean up the cache and garbage faster?

The steps are as follows:

1. Open the Aauto Quicker app, click the three horizontal icons in the upper right corner of the home page, and click Settings.

2. Click Storage Space.

3. Click the cleaning behind the cache and the management behind the draft box, click the three points in the lower right corner of the draft box, and then click Delete.
