A friend of mine got herself a new Xperia 10 and wants to encrypt the SD card. It seems this option is no longer available - previously there was a “Encrypt SD card” option in settings - but no more. Apparently it was also possible to use the SD card as “Adoptable storage” - but no more.

Is it at all possible to encrypt an SD card on Android (15) or is de-googling the only option?
