## FAQs
### Q: Which operating systems can the PinePhone Pro run?
A: The device ships with postmarketOS, an Alpine-Linux-based mobile OS, and is designed to let users install other Linux distributions as well.

### Q: How much internal storage does it have?
A: Wikidata lists 4 GB of storage; users can add more space via the microSD card slot.

### Q: Is the hardware open source?
A: Pine64 markets the PinePhone Pro as open hardware, giving developers access to schematics and the ability to modify drivers and firmware.

### Q: What processor powers the phone?
A: A Rockchip RK3399 SoC provides the computing power for the device.

## Why It Matters
PinePhone Pro is significant because it is one of the few smartphones built from the ground up for Linux rather than Android. By pairing an open hardware platform with mainline-friendly components like the Rockchip RK3399, Pine64 gives developers and privacy-minded users a phone whose software stack they can audit, modify, and redistribute. The inclusion of postmarketOS—an active mobile distribution that reuses standard Linux packages—means owners receive security updates and new features on a timetable driven by the community, not a carrier or OEM. In an era of locked bootloaders and opaque firmware, the PinePhone Pro serves as a reference device for mobile Linux advancement and as a daily-driver option for enthusiasts who refuse to cede control of their personal computer/phone to proprietary vendors.

## Notable For
- Ships with postmarketOS, a rare Linux-first mobile OS
- Open hardware design invites community firmware and driver work
- Uses the well-documented Rockchip RK3399 SoC, easing mainline kernel support
- microSD expansion plus USB-C provides flexible storage and peripheral options
- One of the few 2021-era smartphones explicitly marketed to Linux developers

## Body
### Hardware Overview
The PinePhone Pro centers on the Rockchip RK3399 SoC, combining dual Cortex-A72 and quad Cortex-A53 cores. The device includes 4 GB of RAM and 4 GB of on-board flash, plus a microSD slot for additional storage. External interfaces consist of a USB-C port and a 3.5 mm stereo receptacle.

### Software Stack
postmarketOS, derived from Alpine Linux, is the default operating system. Because the hardware uses components with existing mainline kernel support, users can build and boot alternative Linux distributions with minimal vendor blobs.

### Open Hardware Approach
Pine64 publishes schematics and assembly files, allowing researchers to inspect the design and create custom firmware. This transparency aligns with the goals of the broader open-source community that maintains postmarketOS.

### Community and Documentation
The project wiki, GitLab repositories, and chat channels provide build instructions, safety guidelines, and software images. The 20 sitelinks associated with postmarketOS reflect an active documentation ecosystem that supports both developers and end-users.
