Make it bearable
1
Drop context to 2K — saves ~1.1 GB of KV cache and a little speed.
2
Close every other app before loading — the 1.9 GB headroom is real; Android may kill the app otherwise.
3
Expect throttling after ~10 min of sustained generation on a phone chassis.

Run it on this Huawei phone
Use PocketPal's official APK. This manual route is for Huawei phones that still run Android APKs. HarmonyOS NEXT devices cannot use Android apps.
1
Open PocketPal's official GitHub Release. Use the developer's release page, expand Assets, and download
app-prod-release.apk. Do not use an APK mirror or a similarly named third-party site.2
Install that downloaded APK. Android may ask you to allow installs from your browser or Files app. Allow it only for this install, then turn that permission off again. If the phone says Android APKs are unsupported, stop there.
3
Add the exact model in PocketPal. Open Models → + → Add from Hugging Face, then paste
ibm-granite/granite-4.2-30b-GGUF.4
Choose the Q2_K GGUF file. The download is about 10.9 GB. Use Wi-Fi, keep the app open, and avoid mmproj, vision-projector, or other helper files.
5
Tap Download, then Load. Start with a 4K (4096-token) context and the default Android backend. Send “Explain why the sky is blue in three sentences.”
6
Check offline use and future updates. Turn on airplane mode and ask again. If it replies, the model is local. For later updates, return to PocketPal's official GitHub Releases page.
