In the update notes, Apple says users can “experience spatial audio and enter a new dimension in sound on compatible devices.” In a support document, Apple adds that you’ll “need an Android device that supports Dolby Atmos.” You’ll also need a pair of wired headphones since Apple doesn’t support spatial audio in AirPods on Android devices.
But while Apple says “built-in speakers on an iPhone XS or later (except iPhone SE), iPad Pro 12.9-inch (3rd generation or later), iPad Pro 11-inch, or iPad Air (4th generation)” as well as AirPods and most Beats headphones will support Dolby Atmos, the same isn’t true for Android phones. For example, the Pixel 5, which was released last October, doesn’t show the Dolby Atmos toggle. The Galaxy S10 does, however.
Lossless, however, is available on all Android phones, though you’ll need an external DAC—or possibly an LG phone with a built-in DAC—to hear the highest-quality recordings. And of course, high-res lossless tracks will consume more data due to their size.
Michael Simon has been covering Apple since the iPod was the iWalk. His obsession with technology goes back to his first PC—the IBM Thinkpad with the lift-up keyboard for swapping out the drive. He's still waiting for that to come back in style tbh.
