h2. General freedom issues on the Galaxy S 3 (I9300):
|8||1||Denis 'GNUtoo' Carikli||
* The bootloader is proprietary and signed.
|9||9||Denis 'GNUtoo' Carikli||
* Some peripherals do require proprietary firmwares to work, some of which have to be loaded by the system: See the "Missing without non-free firmwares" status in [[ReplicantStatus]].
|10||11||Denis 'GNUtoo' Carikli||
* The bootrom is the first code that is executed, it's stored in a read-only memory: see "freedom-privacy-security-issues":http://www.replicant.us/freedom-privacy-security-issues.php for more details.
|11||12||Denis 'GNUtoo' Carikli||
* The hardware is proprietary, and we are not aware if any its schematics is available somewhere on the Internet.

h2. Modem related:
|14||6||Denis 'GNUtoo' Carikli|
|15||5||Denis 'GNUtoo' Carikli||
The modem runs non-free software, which is loaded but not shipped by Replicant.
* When using flight mode, The main CPU has to ask the modem to power itself off.
|17||1||Denis 'GNUtoo' Carikli||
* The modem is isolated:
** It doesn't use shared memory with the CPU, instead it uses an "HSIC" bus.
|19||12||Denis 'GNUtoo' Carikli||
** We are not aware of it being able to access the GPS, but it woulnd't be surprising if it still could (by having a direct connection to it: since no schematics are publically available we have easy no way to check).
|20||3||Denis 'GNUtoo' Carikli||
** It has no access to the other CPU peripherals.
