The PinePhone Pro is a smartphone developed by Hong Kong–based computer manufacturer Pine64. The phone is the successor to the PinePhone released in 2020. The default operating system is Sailfish OS (previously Manjaro, with Plasma Mobile as the user interface). The device is a developer platform with open hardware specifications but with unfinished software. The target group of the device is free and open-source software developers who will develop the software. The device was first shipped to developers in December 2021, and in February 2022 devices were made available to consumers. The PinePhone Pro was officially discontinued in August 2025, as it didn’t sell well enough to keep production going.
The phone has hardware Kill switch for shutting down network connections, microphone, speaker, and cameras. The device has Pogo pin for attachable backs compatible with the original PinePhone.
Das U-Boot is used as the default Bootloader and it supports booting from an SD card. The bootloader can be replaced, as there are alternatives, such as Tow-boot. The main image sensor driver has been added to the mainline kernel by Sony. Modem firmware of the Quectel EG25-G is based on a proprietary Android userspace, though an unofficial open-source version exists (actually mostly open-source: the custom firmware replaces most proprietary components, except for baseband firmware and the TrustZone, which is signed by Qualcomm).
In the middle of 2022, the software stack was under development, resulting in the hardware not supporting the software. The first images from the camera were taken in May 2022. Most widely-supported hardware is in a heavily patched downstream kernel called Megi kernel. There is alternative operating systems focusing on mainline Linux kernel support, such as PostmarketOS.
