2. Camera Not Working

The camera may crash or show a “Can’t connect to camera” error.

Fix:

• Install a third-party camera app like Open Camera (works reliably).
• If the stock camera is needed, replace libcamera.so with the version from the stock Samsung firmware (requires root).
• Pro tip: Disable “Zero Shutter Lag” in camera settings to improve stability.

Fix 1: Correct APN Settings

To fix data connectivity issues, ensure that your APN settings are correct. Go to Settings > Mobile networks > Access Point Names, and verify that your APN settings match those provided by your carrier. You can also try resetting your APN settings to their default values.

Fix 2: Update Kernel and Firmware

Ensure that your kernel and firmware are up-to-date and compatible with your device. You can check for updates in the Settings > About phone > System updates menu.

Important Notes Before Flashing

• This is an unofficial build – no guaranteed OTA updates.
• Always make a full TWRP backup of your current system.
• Use TWRP 3.2.x or newer for flashing.
• Recommended baseband: G531HXXU0AQA1 or later.

2. Bootloop After Installation (April 19 Build Specific)

If the device is stuck on the LineageOS boot animation after flashing the April 19 build.

The Fix: This usually happens if the existing Vendor partition is outdated.

1. Download the latest Stock Firmware for the SM-T531 (use a tool like SamFirm or Frija).
2. Extract the NON-HLOS.bin file from the stock firmware (this is the modem/vendor partition).
3. Flash this file via Odin or TWRP to ensure the vendor partition matches the LineageOS expectations.

1. RIL / Mobile Data Fix (3G Connectivity)

Many users report that mobile data (3G) does not activate automatically after flashing this build.

Fix:

• Go to Settings → SIM Cards → SIM 1 Settings.
• Tap Access Point Names (APN) → select the three-dot menu → Reset to default.
• If that fails, manually add your carrier’s APN.
• For some variants, flashing the RIL-Fix-gtel3g.zip (available on XDA) right after the ROM resolves the issue.
