How to get rid of the cloud on the desktop of Coolby mobile phone?

Click on the blank part of the desktop, and then there is a free weather below. Just click in and click the first one that doesn't work.

Is Coolby a different brand of mobile phone?

Not really. It's also a domestic brand. I used to be famous as a function machine, but later I came out with a smart phone. His skills can't keep up. The produced mobile phones all run on the memory of 1G, and the resolution is 960x560, which is not cost-effective.
