Version (14.1): This build is based on Android 7.1.2 Nougat.

Release Date (20180419): This specific version was compiled on April 19, 2018. The Not-So-Good:

Status (UNOFFICIAL): This means the build was created by an independent developer (often found on community forums like XDA Developers) rather than the core LineageOS team

. Unofficial builds do not receive automatic "Over-the-Air" (OTA) updates from LineageOS.

Codename (gtel3g): This is the internal device identifier for the Samsung Galaxy Tab E 9.6 3G (typically model SM-T561). Key Considerations

Installation Requirements: Installing this ROM requires an unlocked bootloader and a custom recovery tool like TWRP. Samsung devices specifically often require tools like Odin or Heimdall to flash the initial recovery.

Stability: As an "Unofficial" build from 2018, it may have hardware bugs (e.g., issues with GPS, camera, or specific sensors) that were never patched.

Security: Since this is based on Android 7.1 and dates back to 2018, it lacks years of critical security patches. It is not recommended for devices used for sensitive tasks like banking.

Google Apps: LineageOS does not include Google services by default. You would need to flash a separate "GApps" package (like OpenGApps) immediately after the ROM to use the Play Store. Modern Alternatives
