Google today said it is introducing updated file sharing features that will make it easier for Android users to send files to iPhone users. Quick Share is already compatible with Apple's AirDrop feature on select Android devices, but Google says the feature will expand to Samsung, OPPO, OnePlus, Vivo, Xiaomi, and HONOR devices in 2026.
I would actually assume the opposite. Transferring apps is relatively easy: get a list of installed apps, check the Play Store for the equivalent Android version, and download it.
Transferring app settings is potentially much harder because it depends on how each app handles settings. Could be a minefield of incompatibilities.
