Andrew_Kim86, Feb 5, 2019 : Who are the users? - Android users with longer screen ratios such as in the oneplus 6t who also use apps that require more traditional aspect ratios (i.e. snapchat, instagram stories). Developers of new apps testing on these devices will also heavily need this feature. What is the proposed function? - in settings, every individual app will be able to turn on a traditional aspect ratio. When the user opens any of the selected apps, they will open with the screen unused at the top and bottom, and displaying the app as if it were on a traditional aspect ratio screen. The screen would return to the full ratio when switching to any apps without the setting turned on or switching to the home screen or recents. What is the user value? - This eliminates several issues with popular apps on snapchat and instagram. On snapchat, the quality of the image gets better and reduces how zoomed in the camera seems. Additionally, it sends and displays snaps with correct ratios eliminating the black bars displayed on the sides or the top and bottom of photos when receiving snaps. For instagram, specifically instagram stories, it eliminates the problem of stories being cut off on the sides due to the image being stretched and cropped. Overall on these two apps, it makes it easier for content viewing and sharing, however still gives the user ability to customize which apps will require the new aspect ratio and which apps are already optimized for it. Finally, developers can test what their apps look like in the two aspect ratios when testing them on a non traditional aspect ratio. This feature can eliminate the bugs that can be seen before they release the app to different screen ratio sizes. If there are existing comparable functions in the smartphone industry, how is your proposed feature superior? - There are already ways for developers to test their application on different screen sizes, but no other companies in the smartphone industry provide and easy way for average users to control these sizes. In the case of apple, instagram and snapchat are personally optimized for their devices, which is a luxury that unfortunately has skipped android users. Even so, this ability can provide more convenience to users in a new way. Youtube already partially does this by giving users the ability to watch the video in full with black bars on the side, or cropped at the top and bottom. It seems that this feature is necessary for viewing youtube videos, so it would be great to have it for every app for higher levels of customization for users.
