Question about CM updates on Indian version. [re:eek:TA vs Manual Updates] topic

I apologize if this has been asked, a brief search didn't show anything related.

So due to the recent development it seems like handsets sold in India won't be getting CM updates, but users can manually perform updates, correct?

Has anyone been doing manual updates over the OTA updates? Is the process tedious?

[Q] Ambient Display vs Manual brightness topic

What do people find the most efficient way of deciding between ambient display and manual brightness?

Ambient display gives a pink tint when on low brightness manual does not.

Manual brightness is a little brighter than ambient display so is this having a negative impact on battery.

What are your thoughts on this?
