  • Original Camera Video Recording application - as it's the LineageOS camera app, it doesn't save. This is now replaced by Aperture camera application from LineageOS 20 which will save video. It's not the fastest but works - hey it's an old device.
  • DRM level 1 (no HD definition). It is practically impossible to achieve level 1 for HD definition. If you need HD definition for your streaming media, stay with stock Samsung ROM.
  • WPA2+WPA3 wifi security on a wifi access point results in no wifi connection. Logcat displays - "WPA: Failed to select authenticated key management type" It's in external/wpa_supplicant_8/wpa_supplicant/wpa_supplicant.c at line 1586
  • Please Note there are crashes due to Mali graphics driver. This occurs in games esp. Clash Royale which will lock up tablet completely. There are crashes occurring in browser, browser based google maps - pinch zooming in/out , and may occur in other graphics intensive operations.
