I'm using ArcGIS Online and have users trying to access an ArcGIS Instant App, using the Nearby template, on their mobile devices. They have the option within their phones, on both Android and iOS, to download the app, to make it accessible from their home screen directly. This app is basically just the browser version but without the browser controls surrouding it - basically in a full-screen mode.
When you download the app, it defaults to being called 'nearby' and has a logo which is a white background, with a grey square containing a cross (+), as seen in the attachment; this isn't a logo I recognise at all - not our organisations or the Esri or Instant Apps one, althought potentially one specific to the Nearby template. On iOS you have the option to rename the app to something more sensible, however this option doesn't exist within Android, and neither have the option to change the logo. This is really poor for our end users, making it very unclear what the application actually is without them opening it.
Is this something we can alter? We already have the logo and title set within the Instant App configuration, and looking on ArcGIS Assistant I can't see anything in the JSON or the media that would relate to those items.
We currently do not have support for this in the apps but we can look at adding support for this behavior in a future release. Would you want a custom icon? Or just an icon that more accurately reflects the app? Same with the displayed name - would the app header title be appropriate in your case?
I think the best option would be to use the logo and title used in the app by default, but also have the option to configure it seperately too, given it's probably a different aspect ratio icon and a long title would be truncated.
