Executive summary
The headline point: deleted Android data frequently survives in SQLite free space and journals, recoverable
until overwritten, but the depth of acquisition decides what can be reached, and file-based encryption and
flash TRIM mean that classic unallocated-space carving works far less often on modern devices, so recovery
depends on depth, the device's encryption and storage, and prompt preservation, with the estate as the route
around what the device no longer holds.

Why does the depth of extraction matter so much?
What are file-based encryption and TRIM, and why do they matter?
So is deleted data on a modern Android phone unrecoverable?
Why does preserving the phone quickly matter?
What if the phone genuinely no longer holds the deleted data?
