Replicant is a free Android - Custom-ROM , which is based on LineageOS , in contrast to this, however, aims to replace all proprietary components with free components.
Replicant is available for various smartphones and tablets . The operating system is sponsored and supported by the Free Software Foundation . The name Replicant comes from the fictional Replicant androids from the Blade Runner movie .
safety
In March 2014, Replicant developers found and eliminated an Android backdoor that was present in many Samsung Galaxy smartphones.
Use restrictions
Since free firmware may not be available for some hardware components, these are not available or only available via more or less short detours. The project clearly documents which functions are supported by a device that can run with Replicant.
Radio technology
Both WiFi and Bluetooth in the devices supported so far (as of August 2019) require proprietary firmware . Bluetooth cannot be used under Replicant. However, it is possible to use RepWifi WLAN via a wireless adapter and the RepWifi WLAN app integrated in the Replicant . For this purpose, the project recommends the use of wireless adapters with certain versions of the Atheros chipset AR9271, as these can be operated with free firmware.
graphic
The graphics processor of all devices supported so far (as of August 2019) requires non-free software. By default, the Android software renderer is used as the software renderer , alternatively this can be replaced by the software renderer LLVMpipe via ADB , or you can switch back and forth between the two at will.
The following problems or can occur when using the Android software renderer :
- Selecting the Panorama mode and start the video recording in the camera app brings to this crash .
- The playback of videos within a web browser or the gallery app is also not supported due to non-free codecs, but is possible with the VLC media player , which must be installed as an app for this.
- Screenshots cannot be taken with the device, but a screenshot can be created with a device connected to a computer via ffmpeg and a script.
- Only the ready-made background images can be selected; However, you can also configure your own images for the lock screen.
- If the lock screen is activated, you occasionally see the content behind it (open apps, etc.) when you unlock the device (this also happens with LLVMpipe).
- It is not possible to display preview images of the individual active windows.
- Switching between apps, apps and the app launcher and different views within an app is sometimes slow, which makes the device appear as if it is not responding.
- The Trebuchet app launcher sometimes crashes when you use it to open directory links on the home screen (this can also happen with LLVMpipe).
