How to remove the power by android logo on vivox5m boot

There is no way to remove it! Unless you can start from the bottom and modify VIVO's system.

Google (Weibo) is a household name, but although Google's Android operating system occupies a large market share in the global smartphone field, Android itself is not well-known enough. Google allows hardware manufacturers to design their own user interfaces based on Android, so it is difficult for ordinary users to find that Google Nexus 5, HTC One M8, and Samsung Galaxy S5 actually use the same operating system.

Google hopes to change this situation, and one of its measures is to require new mobile phones to display the slogan "Powered by Android" (meaning "Android Power") when starting up. When turning on the HTC One M8 or Samsung Galaxy S5, users will see this slogan clearly displayed below the company branding. And these two phones display more than just text. Both HTC and Samsung use the classic Android LOGO, which is the picture used in the startup animation of the original Android phone HTC G1.

This is the regulation proposed by Google in the "Google Mobile Services Agreement" for new Android phones. Google has proposed special regulations for the "Powered by Android" slogan. Hardware manufacturers' new smartphones must display this slogan if they want to use the Google Play app store. HTC and Samsung have come up with new ideas when launching new phones with the tagline, but the feature was requested by Google.
