Two phones, one Synology share, DSM 7

Lab reconstruction / anonymized. Not a customer testimonial. No star ratings.

NAS in a cabinet, Ethernet to the desk, phones on 5 GHz Wi-Fi. DSM user album on that share only, guest off. The iPhone failed nas.local until Local Network permission was granted. After that, 192.168.1.32 was more stable; mDNS flakes on this router.

Xiaomi 14 HyperOS 2.0.5 kills background work aggressively. The WorkManager notification can stay up while the job is already dead. Reopening the app is the normal resume path.

HEIC is 44% of the combined library, all from the iPhone. The Xiaomi side is mostly JPEG. Object keys do not collide because they carry a device dimension. Do not rename the iPhone folder in File Station; the Xiaomi claim will miss the physical path.
