I have a samsung A30 cellphone that runs Android 10 and I basically need to recover my deleted files. In order to do that, I need to know the filesystem because forensic tools require such information. I made a small research, but I couldn't find any information on Android 10 OS's file system. So what I am asking is what file system does Android 10 have and do file systems depend on Android versions? Any help will be appreciated.

  • if your device is rooted it's ext4 otherwise it's encrypted (and recovery pointless) – alecxs Nov 27 '20 at 13:01
  • Thank you both @beeshyams and alecxs. I will try to root my device now and lets see how it goes. – KontrCode Dec 4 '20 at 10:23
  • let me clarify: you can not recover files because your device is encrypted. once the encryption keys are wiped, data is unrecoverable. this is true for FDE full-disk-encryption on factory reset, and for FBE file-based-encryption on deleted files. be aware rooting involves factory reset (see step 4). no hope, sorry – alecxs Dec 6 '20 at 11:59
  • @alecxs so you say it is impossible to recover an unrooted android mobile phone, right? Recovering a wiped (factory-reset) cell phone is possible only on rooted devices. – KontrCode Dec 6 '20 at 12:38

according to this TWRP the Samsung Galaxy A30 SM-A305F is shipped with Android 9.0 (Pie) FDE full-disk-encryption

BoardConfig.mk

# Filesystem
TARGET_USERIMAGES_USE_EXT4 := true
TARGET_USERIMAGES_USE_F2FS := true

The file system type depends on ROM and can be F2FS or EXT4
