Second batch of open source Linux phones Librem 5 “Birch” to start shipping

The Librem 5 Linux phone, codenamed Librem 5 Birch, delivered a second batch of devices to consumers yesterday with batch iteration shipping. Librem 5 Birch was scheduled to ship two weeks ago, but had to delay shipments due to a lack of resistance that prevented the USB port from functioning properly. This issue has now been fixed and Librem 5 Birch was officially shipped yesterday.

Officially, from the first Librem 5 Aspen to the present Librem 5 Birch, the team has provided many hardware improvements, such as optimizing antenna design, adding shield protectors to all components on the PCBA, using rubber bumpers to enhance the tightness of the components, and using solid clips to stabilize WiFi and cellular data cards, use shorter cables to clean up cabling, control more precise overall tolerances, and increase heat efficiency.

Although hardware improvements have been made, Librem 5 Birch still has some software issues. Officials say work on software improvements is under way, and the team has identified two software issues during testing: power-on delays and call routing errors. Specifically, to start Librem 5, you need to disconnect it from the power supply and press and hold the power button until the phone starts. A call routing error means that even if the current call is established (e.g., the two sides of the call are connected correctly), but the call is not routed (neither party can hear or send a voice), the team indicates that it will take several days to fix the error.

In addition, the team hopes to address thermal and battery life issues through software updates. For more information, check out Puri.sm.
