Over the past months, we have been asked a lot whether Replicant is going to be running on the Fairphone. The goal behind Fairphone, as its name suggests, is to build a phone that is “fair”. This covers a lot of different aspects that the Fairphone company took care of: such topics as using fair and conflict-free resources, ensuring that all workers along the supply chain get a fair wage, improving the handling of electronic waste, being transparent about the cost of each part of the device, its technical specifications and encouraging open and flexible designs.
We are really glad to see a company producing electronic devices taking care of such many important aspects as social conditions of workers, ecology and handling of e-waste as well as transparency and being “technically open”.
What we are especially interested in, at the Replicant project, is how good the device will be when it comes to software freedom. Hence, we have spent some time investigating the device, even though it is not out yet. Thanks to the cooperation of Fairphone, we were able to draw a quite complete picture of it.
The Fairphone will ship with a modified Android 4.2 version. An overlay interface was developed for the device and should be released as free software, but what we are really interested in is the parts that deal with the hardware. First, the Linux kernel source code for the device will be released (it is copyleft software so this is an obligation). It will also be possible to build the kernel from source and install it on the device without the need to sign the kernel with the manufacturer’s key. Actually, there should be no signature check on the Fairphone for the kernel or the bootloaders. Some of the bootloaders (maybe all of them; we cannot tell for sure at this point) are free software and it should be able to replace them with a free build. We are a bit worried that the tools to flash the Fairphone may be proprietary, but if the bootloaders are free and/or there is root access out of the box, there will be ways to work around this problem. On the system side, some of the libraries that deal with the hardware have been released as free software for devices that use the same platform (Mediatek 6589), so the basic required features such as audio will likely work. We are also confident we will be able to handle the modem with free software (that means telephony and such will work).
Fairphone is really trying hard to get Mediatek to release as many components as free software as possible, but they don’t have the source in the
