    - What does GrapheneOS do about non-resettable - hardware identifiers like IMEI, SIM or phone serial number? + Can apps access hardware identifiers?

    -

    Starting with the Android 10 specification, apps can no longer extract the phone's - IMEI or Serial Number, SIM Card Serial Number, Subscriber ID, MAC Address or other - non-resettable unique device identifiers, even if granted access to - READ_PHONE_STATE. Apps must have the - READ_PRIVILEGED_PHONE_STATE new to Android 10 in order to get access to - any of these non-resettable, persistent device identifiers. Apps using the Android 10 - API will recieve a SecurityException error, and any older apps simply get - an empty value if the READ_PHONE_STATE permission has been granted to them, - or a SecurityException error if they don't. MAC Addresses are randomized - per WiFi network on GrapheneOS. Apps, even if granted full network access, cannot read - nor change the MAC Address.

    +

    As of Android 10, apps cannot obtain permission to access non-resettable hardware + identifiers such as the serial number, MAC addresses, IMEIs/MEIDs, SIM card serial + numbers and subscriber IDs. Only privileged apps included in the base system with + READ_PRIVILEGED_PHONE_STATE whitelisted can access these hardware + identifiers. Apps targeting Android 10 will receive a SecurityException + and older apps will receive an empty value for compatibility.

    GrapheneOS does not utilize Advertising IDs, even though the Advertising ID - normally seen on Android and iOS devices is resettable.

    ANDROID_ID is persistent between application installs but is resettable. - Pull requests are welcomed in this area.

    +

    GrapheneOS only makes a small change to remove a legacy form of access to the + serial number by legacy apps, which was still around for compatibility.
