🧪 Tested Releases (Tester Log)

LineageOS 23 (Android 16)

  • Build Date: Dec 21, 2025
  • Maintainer: anna-adnana
  • Status: NOT RECOMMENDED for Daily Driver.
  • Issues: Call reception is broken. The device receives the signal (remote caller hears ringing) but the local UI does not trigger. No call history logs.

crDroidOS 11.12 (Android 15)

  • Build Date: Dec 23, 2025
  • Maintainer: anna-adnana
  • Status: RECOMMENDED.
  • Notes: More mature IMS stack. Best option for users requiring functional telephony.

ℹ️ Essential Fixes & Post-Install

1. Fixing Inbound Calls (IMS)

To attempt fixing radio issues on Samsung hardware:

  • Go to Phh Treble Settings -> Telephony.
  • Enable "Request IMS Network".
  • Enable "Allow binder thread on incoming calls".
  • Workaround: If calls still fail, set Preferred Network Type to 3G to force legacy voice protocols.

2. Performance & Battery

  • Deep Sleep: Verified 2% drop over 8 hours with Fingerprint active.
  • Graphics: Disabling HW Overlays improves UI smoothness on Helio G85.

3. App Verification (Telegram/WhatsApp)

Since SMS reception is unreliable on early A16 builds:

  • Use Google Account Authentication for Telegram login.
  • Alternatively, use a secondary device to receive the SMS and enter the code manually on the A06.
