This time vivo is still quite wronged! I just tried it with the vivo mobile phone in my hand, I can't find the app treasure in the vivo app store, I can only search in the browser, and the installation will prompt "unofficial app store APP", but it can be installed normally. This reminder seems to be that all mobile phone brands, as long as it is downloaded and installed through unofficial channels, there will be a prompt, right?

This phenomenon is widespread, unofficial stores download the app, when installing the app prompts the risk, and then will jump to the mobile app store to let you download the app store, also to protect the user's safety. And each brand has its own store, vivo mobile phone with vivo's own app store, reasonable. What do you think?
