YES — Runs, barely
Grade C · 47/100 · formula estimate
What this means
Our estimate says Fara 1.5 27B should fit, but there is very little memory left for the operating system and other apps.
Download the Q4_K_S version, which is about 16.5 GB. We expect it to use about 19.8 GB of the roughly 20 GB available to a model on this phone.
At the estimated speed, a roughly 300-word answer may take about 3 minutes to finish.
This result is calculated from the phone and model specifications. It has not been measured on this exact phone and setup.

Make it bearable
1
Drop context to 2K — saves ~1 GB of KV cache and a little speed.
2
Close every other app before loading — the 0.2 GB headroom is real; Android may kill the app otherwise.
3
Expect throttling after ~10 min of sustained generation on a phone chassis.
