Installing Solitaire on a Light Phone III

Get the APK

Grab LightSolitaire-<version>.apk from the latest release.

Check what you downloaded

Every release ships a .sha256 sidecar:

sha256sum -c LightSolitaire-1.0.0.apk.sha256

The APK is signed with a personal sideload key. Its certificate fingerprint is:

SHA-256: 38:6E:DB:70:91:94:77:07:A8:12:58:7A:F8:C3:7B:08:73:BB:2C:DE:88:96:3E:95:20:57:4C:C4:5B:C0:12:8C

Check it yourself with apksigner verify --print-certs LightSolitaire-1.0.0.apk. If that fingerprint ever changes, the APK was not built from this repository's key — don't install it.

Install

Turn on Developer Mode in the Light dashboard, then:

adb install -r LightSolitaire-1.0.0.apk

Solitaire shows up in the LightOS toolbox. To get updates automatically, point Obtainium at https://github.com/gi-os/LightSolitaire with the APK filter LightSolitaire-.*\.apk — that skips the .sha256 sidecar.

What Light will and won't support

This is signed by a personal key, not by Light. In LightOS terms it needs the Any tools setting, which is the tier where you own getting things installed and uninstalled. It's built entirely with the official SDK and asks for no permissions at all, so it should be a candidate for the Tool Library once submissions open — at which point Light would sign it themselves and this key stops mattering.

Android only accepts an update signed by the same key that installed the app. If the signing key ever has to change, you'll have to uninstall first, which wipes the saved game.

Uninstall

adb uninstall com.thelightphone.solitaire
