What this means
The checked Q4_K_M version should run, but replies are likely to arrive slowly. The smaller Q3_K_M version is the safer choice.
Download the Q3_K_M version, which is about 4.7 GB. We expect it to use about 6.2 GB of the roughly 9 GB available to a model on this phone.
At the estimated speed, a roughly 300-word answer may take about 49 seconds to finish.
This result is calculated from the phone and model specifications. It has not been measured on this exact phone and setup.

Drop to Q3_K_M (4.7 GB) — it runs comfortably here at ~8.1 tokens/s. Recommended over Q4_K_M.
2
Drop context to 2K — saves ~0.3 GB of KV cache and a little speed.
3
Close every other app before loading — the 1.8 GB headroom is real; Android may kill the app otherwise.
4
Expect throttling after ~10 min of sustained generation on a phone chassis.
