Yes...A11 encrypts the files/folders in SDCARDSo basically, it seems that Android 11 is more "secure" than Android 10, speaking only about recovery accessing memory... right ?
and the Recovery software is unable to decrypt it
( unless a decrypt patch is flashed, in which case,
the phone becomes less secure, but there is more 'convenience',
eg. if flashing .ZIP files directly from SDCARD )
