GrapheneOS has been the gold standard for privacy and security on the Android ecosystem for quite some time, where in reality there are no 'peers'.
Any other so called (Android) 'privacy' operating system does not compare.

Apparently the gold standard for data extraction from smartphones is Israel's forensic data extraction tool from Cellebrite.
It cannot gain access to data, running an up to date version GrapheneOS on a 7th generation Pixel phone.
See leaked screenshot from a memo on Cellebrite:
Currently GrapheneOS is only available on Google's Pixel smartphones, except for the Pixel 11 series.
As of 2027 GrapheneOS will be available on Motorola's flagship phone, that being the Signature 27 series.
When a phone is first turned on, it is in a state called BFU (Before First Unlock), where data on the device is encrypted and the encryption key only decrypts the data once an unlock code is entered, where the decryption key then resides in the phones memory.
A test has been performed on a GrapheneOS Pixel in its 3 various states:
- After being turned on, with no PIN code entered, known as BFU,
- After a PIN code has been entered, known as AFU (After First Unlock),
- In an unlocked state.
Spoiler Alert: It should come as no surprise, that data can be extracted from an unlocked phone.
This is shown in the video by Aussie Cyber-security creator Ahmed Khanji:
The tools used in the video are not from Cellebrite, but rather seem to be free tools on github: ALEX and ALEAPP.
Even though Mr. Khanji mentions that the phone reboots every 18hrs, therefore clearing its memory and returning the phone to a BFU state, that setting is only by default.
Depending one one's threat model, the 'Auto reboot' function can be set to as little as 10 minutes:
The function can be found by searching for "Auto reboot" in Settings
Settings -> Security and Privacy -> Exploit protection -> Auto reboot.

GrapheneOS protections against data extraction from locked devices
It is VERY important for Aussies NOT to be ignorant or complacent about their online footprint, data privacy & security, and most importantly to be aware of GrapheneOS, as Australia has become a Socialist Surveillance State.
It's basically a totalitarian state falsely advertised as a democracy.
It's a fascist state, a corporatocracy, a 'money for mates' colony or whatever else one would like to describe Australia as.
