Freedom issues on the Galaxy S 3 (I9300):

  • The bootrom code (which is read-only by definition) is proprietary.
  • The bootloader is proprietary and signed: GalaxyS3I9300Bootloader
Modem related:
  • 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).
    • It has no access to the other CPU peripherals.
  • 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.
