Why doesn't the screen of Pioneer e9 1w mobile phone download and install software show wet?

You mean that when downloading software, the downloaded software is not displayed on the desktop.

Well, in that case, it has something to do with your mobile phone settings, and it is set as a silver bin.

Mode, this can be changed by yourself.

I used to have this problem with my mobile phone.

But then I downloaded an app on my mobile phone, and then I could display it on it.

Come out and ask for something to download

Everything I downloaded was downloaded from the App Store.

You can download this software on your mobile phone and see if it can be displayed.
