💡 Installation & Troubleshooting (Android 13/14)
Heimdall is distributed directly on GitHub for now as we don't have a Google Play Console developer license yet. Because you are sideloading outside the Play Store, Android will show standard security checks on first setup:
- Allow Unknown Apps (Chrome / Files):
- Settings Path: Phone Settings → Search for "Install unknown apps" → Select Chrome or Files → Toggle on Allow from this source.
- (Or from the install prompt: Tap Settings on the popup → Turn on Allow from this source → Press Back → Tap Install).
- Google Play Protect:
- Tap More details → Tap Install anyway (Heimdall is 100% offline with zero internet permissions).
- To pause scanning: Open Play Store → Tap Profile icon (top right) → Tap Play Protect → Tap ⚙️ Settings (top right) → Turn off Scan apps with Play Protect.
- Restricted Permissions (if SMS toggle is greyed out):
- Open phone Settings → Apps → Heimdall → Tap
⋮(top right) → Tap Allow restricted settings → Verify with fingerprint/PIN.
- Open phone Settings → Apps → Heimdall → Tap
- Set as Default SMS App:
- When Heimdall launches, it automatically prompts: "Set Heimdall as your default SMS app?" → Select Heimdall → Tap Set as default. This grants SMS access and loads your existing inbox.
