Three things about the PinePhone workflow are easy to hit and currently undocumented: - The adb forward is tied to the connection to the modem and is silently dropped when that connection is re-established, so the web UI stops answering while `adb devices` still looks healthy and recording continues. - `pinephone-start-adb` and `pinephone-stop-adb` write `AT+QCFG="usbcfg"`, which resets the modem even when the requested composition is already active. The modem needs about a minute to boot and the phone has no cellular service meanwhile. Retrying faster than that keeps the modem in a reset cycle, ModemManager never finishes its QMI probe, and mobile data stays down until the modem is left alone. - Where ModemManager or eg25-manager manages the EG25-G, it holds the AT interface and enabling adb fails with `detach_and_claim_interface ... Resource busy (os error 16)`. Document each with the symptom and the way out.

While installing Rayhunter on a PinePhone (Kali, phosh), I ran into three specific behaviors that are not currently mentioned on the PinePhone page. Each of these required significant debugging time, and one temporarily disabled my mobile data, so I believe they are worth documenting.
I observed all three issues on a PinePhone with an EG25-G running Rayhunter v0.12.0:
This update is for documentation only. I have added three short sections to doc/pinephone.md covering the symptoms and the fix for each issue. No code changes were made.
