General freedom issues on the Galaxy S 3 (I9300):¶
- The bootloader is proprietary and signed.
- 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.
- The bootrom is the first code that is executed, it's stored in a read-only memory: see freedom-privacy-security-issues for more details.
- The hardware is proprietary, and we are not aware if any its schematics is available somewhere on the Internet.
Modem related:¶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.
- The modem is isolated:
- It doesn't use shared memory with the CPU, instead it uses an "HSIC" bus.
- 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).
- It has no access to the other CPU peripherals.
- Terminal profile
- Investigate its terminal profile
