Hi @graz did you try flashing the LOS 16.0 build on your device. The roll back from Pie to previous versions is known to cause issues on most devices. Can confirm this because we have been testing Pi/e/ builds the last couple of weeks. The way we are flashing the test Pi/e/ ROM’s is first flash the latest stock ROM through Miflash which would be on Pie and then flash the Pi/e/ ROM ( format + wipe system + data + cache).
