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
