Observed result
Both phones recorded approximately 212 seconds before an intentional hangup. Sampled playback logs reported zero loss, underrun and CRC-drop counters.
Method and conditions
A short-range, two-device RFCOMM voice call. Two-wall separation was reported by the tester; both phones used the debug build. The periodic logs showed average jitter-buffer depths of about 199–203 ms.
What this establishes
Evidence of continuity in this single setup. Zero sampled counters are not a universal 0% packet-loss claim. Distance was not measured; this run does not establish a range guarantee, heavy-obstruction performance or end-to-end voice latency.
