I was running Lineage on the tablet and I am usually very careful about what I allow. I have no idea how it got set to take over main screen at charging time.

Btw, all these distributions (Lineage and Cynogenmod before that) don't benefit from automated updates. So that is another headache to remember to manually reflash/upgrade.

> don't benefit from automated updates

That varies by the ROM. Many do support automated OTA updates. (https://www.androidexplained.com/lineage-os-ota-update-locat...)

Kind of unrelated, but what phones do you use? Also, can you still use Google apps?

You can still use Google Apps, but they must be sideloaded as part of the installation process before you boot LineageOS the first time.

I haven't found a LineageOS device that will pass the SafetyNet checks yet, though.

Is LineageOS still signed with testing keys?

My Galaxy S5 with Lineageos 16 and Magisk passes safetynet.. Thanks to Magisk.

No, and I consider that a feature :) I have Zuk Z2, which incidentally is still the only phone in the world that matches my small list of requisites: reasonably modern, not huge, has Lineage support.

I didn't check properly before I bought a Moto G5... the only Lineage image there is crashes its sound server whenever you connect a Bluetooth headset. I'm trying to get the dev to share their build steps so I can look into what is happening there, but they're not responding :(
