Working with the lineage-14.1-20180419-UNOFFICIAL-gtel3g build for the Samsung Galaxy Tab E (SM-T561) can be tricky because it is an older, unofficial release. Many users face issues with the camera, GPS, or general stability on this specific version. Fixing Common Issues

Camera Connection Issues: If you see "can't connect to camera," first check if your baseband is correct for your region. If the problem persists, a clean flash is often required: wipe the /system, /data, and cache partitions before reinstalling.
Video Stuttering: On the 4PDA forums , a specific patch for "video stuttering and sound sync" issues is recommended for the Tab E series. Correct Installation Guide

Flash GApps (ARM 7.1 Pico is usually recommended for this device).
Flash the keys.zip file often included with this specific build.
Post-Flash: Do not restart immediately. Go back and flash Magisk (v11.6 or later) or SuperSU if you need root access for the WiFi fixes. Should You Update?
