# Can I run Phi-4 14B on Samsung Galaxy S25 Ultra (16GB, 1TB config only)?

Updated: 2026-06-15

**Yes, but tight.** Fits at Q4_K_M (~10.8 GB of ~12 GB usable) but with little headroom, close other apps.

- Model: 14B, Q4_K_M 9.05 GB
- Device: 16 GB ram, ~12 GB usable for weights
- Needs ~10.8 GB at Q4_K_M; recommended quant: Q4_K_M
- Best tool on Android: PocketPal AI

Estimate. Method: weights + KV cache + ~0.8GB overhead. Sources: https://ollama.com/library/phi4, https://ollama.com/library/phi4/tags, https://huggingface.co/bartowski/phi-4-GGUF, https://lmarena.ai/leaderboard.
