The fourth beta of iOS 14.2 and iPadOS 14.2 does not bring anything new, but it improves performance and fixes some bugs. Currently, these betas are available for developers only. This new beta, however, introduces a series of photorealistic backgrounds designed by artists from all over the world, also compatible with the dark theme found from this link.
The most important novelty of iOS 14.2 is the integration of Shazam in the Control Center. With a simple tap, you can easily identify songs without even installing the Shazam app. Additionally, the Control Center in iOS 14.2 also offers revamped new media controls, with content hints when no song is playing. If you are listening to a podcast, at the end of the episode you will see more suggestions directly in the Control Center, and you can play them directly from that screen.
