Ability to customise the Android logo + related logo/brand items
At the moment there is no way to customise the Android logo this leads to inconsistent visual branding.
Enterprises/institutions often use logo variations to address official branding guidelines. For example, a restricted space version of the official logo that is mandated to be used when there is little available space. Such restricted space logos often reduce or totally remove typography to avoid issues of logo/brand integrity that occur when only 30 or 40 pixels of square space is available.
Also, assuming this functionality is added it may be worthwhile to consider placing all the logo and branding (i.e., splash screens too) setup in one central location to make it easier for your App Manager users to configure their institution/enterprise visual brand.
