YouTube may soon enable users to upload thumbnails for custom playlists they create based on a report. Currently, the platform allows uploading thumbnails for individual videos but not for playlists curated by users. This could change soon with a new option being tested for Android devices, as discovered from an APK teardown of the YouTube for Android beta app.
A detailed analysis revealed that code indicating the possibility of users uploading thumbnails for their playlists had been found. The APK teardown of the YouTube for Android beta app version 9.26.33 uncovered a potential feature code-named "CustomThumbnailCreationActivity,” which points towards this new capability.
Additionally, the code includes strings for “upload failure,” which might inform users to retry in case of unsuccessful uploads. There may also be dimension requirements for thumbnails, as small dimensions were referenced as a possible cause for upload failures.
At present, users can only upload custom thumbnails for videos on YouTube for Android, but not for playlists. The current thumbnail is usually derived from the first video saved in the playlist, which can only be changed to another video. This upcoming change could offer greater customization, allowing users to set any image as their playlists' thumbnails rather than being constrained to the existing video thumbnails.
The video streaming platform is also reported to be working on a sleep timer for its Android app. This feature would enable users to set a timer for video playback before it stops automatically. This feature may also appear as a notification on the smartphone’s home screen.
This characteristic was discovered during a dissection of the Android version 19.25.33 APK for the YouTube application. Despite the fact that this capability is already integrated into YouTube Music, it is likewise expected to be incorporated into the video-streaming application.
