This project provides an adapted AOSP/LineageOS GSI specifically optimized for the Samsung Galaxy A03 Core.
The base system uses the LineageOS GSI by Andy Yan, with device-specific adjustments for better compatibility, stability and overall user experience.
You install this at your own risk. I am not responsible for any bootloops, data loss, soft-brick, or hardware damage.
If you are not comfortable modifying your device — stop here.
I am not the original developer of LineageOS or the GSI itself. I only maintain the unofficial adaptation specifically for the Samsung Galaxy A03 Core.
Updates may include:
- device-specific optimizations
- kernel/vendor compatibility fixes
- my optional AIO optimization module
- stability improvements
- Device-specific optimizations for the Samsung Galaxy A03 Core
- Removal of unnecessary components not used on this device
- Hidden Treble Settings for a clean full ROM-like experience To enable Treble settings: ```bash su -c "pm enable me.phh.treble.app/.TopLevelSettingsActivity"
- Offline charging automatically reboots the device (prevents being stuck at the Samsung logo on some kernels)
- VoLTE is not supported
- Incorrect mobile signal bar display (always shows 2 bars regardless of actual signal strength)
The author may release a Magisk module in the future that could fix some of these issues.
