- hardware identifiers like IMEI, SIM or phone serial number?</a>
+ <a href="#hardware-identifiers">Can apps access hardware identifiers?</a>
</h2>
- <p>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
- <code>READ_PHONE_STATE</code>. Apps must have the
- <code>READ_PRIVILEGED_PHONE_STATE</code> 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 <code>SecurityException</code> error, and any older apps simply get
- an empty value if the <code>READ_PHONE_STATE</code> permission has been granted to them,
- or a <code>SecurityException</code> 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.</p>
+ <p>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
+ <code>READ_PRIVILEGED_PHONE_STATE</code> whitelisted can access these hardware
+ identifiers. Apps targeting Android 10 will receive a <code>SecurityException</code>
+ and older apps will receive an empty value for compatibility.</p>
- <p>GrapheneOS does <i>not</i> utilize Advertising IDs, even though the Advertising ID
- normally seen on Android and iOS devices is resettable.</p>
-
- <p><code>ANDROID_ID</code> is persistent between application installs but is resettable.
- Pull requests are welcomed in this area.</p>
+ <p>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.</p>
