[Sony Xperia XA2 ROMs, Kernels, Recoveries, & Other] moderom:
Overall, the Lineagos system is definitely a better alternative to the stock system and there is no need to dwell on that :) Fast, clean, but with some flaws that will hopefully be removed. Thanks to LuK1337 for their time and to Xleng who contributes and helps with the discussion.

OTA Upgrade to Lineage-17.1-20200723-nightly-pioneer

ran properly with the same applications, settings and data as used to be the case.

For obvious reasons, I don't use gapps, store, gmail or google cloud. Perhaps this is where some of the problems come from? It is worth for the creators to look at this dependency.

In the above edition of the system, I confirm that the gestures in the first "Navigation using gestures" option (with the cog on the right) work great and eliminate the mindless bottom bar with buttons. As a result, we have a screen that is 6-8 mm longer and a larger field of operation.

The dark mode is very trendy and obviously desirable because it improves ergonomics. Any self-respecting application has this option. On reedit / lineageos I was rebuked for such attention. That's why I don't really want to write there. The lineageOS team is laughing, she is MEGA insulting and cannot accept comments :)

As for the noise and the Bravia engine ... it's a pity that you can't add the keys and thus activate the stock camera. I will test the LoS camera ... especially since it no longer clutters the image with the "green stripe". I will continue in a dedicated topic:

I have crossed out the lines with previous comments that have already been fixed.

Still not fixed:

*

disappearing phone book .. just like in previous LoS releases, it just suddenly disappeared in this one. As I remember correctly, it happens once or a few days after uploading a new system. After that, it's quiet. At the moment I am protecting myself with the built-in * .vcf contact export option

I think I found a solution: slot 2 (it's on the second, deeper tray) does not support data transmission, because after swapping cards, the internet appeared. This is confirmed by the card statuses after entering the code:

* # * # 4636 # * # * - Test menu (phone information, battery information, usage statistics, Wi-Fi information) one of the cards has the annotation "enable transmission". I don't know if I can turn it on safely? thus get rid of the problem.

New BIG faults:

A

SMS when the screen is locked, it seems like a delay, because the signal and the icon appear only after unlocking the screen. the error occurs intermittently.

B

defeat - it is not possible to disable one card!

tasker supposedly does the trick, but that's not the way to go. after all, this is the basic functionality! in addition, the preferences of sim 1 & 2 cards should be in the "SIM cards" tab and not thoughtlessly duplicated under each of the numbers in the "network and internet" menu. In previous systems, e.g. LoS 16, it was more logically arranged:

Another thing, the two tabs "network and internet / given number" and "cellular network" lead to the same settings window. Unfortunately, the need for another click and the "advanced" tab are still not gone. After all, everything fits quietly in one area of ​​one window. Due to such organization of tabs, searching for a given function takes a few or a dozen more clicks. Unfortunately, the loupe does not always find something and, importantly, it does not suggest the header of a given menu, but immediately the execution line.

Original Android 10 (on Samsung s9) has those options:

so wheree is it ?!?! :)

C

no possibility to choose several preferred network modes ... there was a whole list in LoS 16

D

light intensity sensor ... sometimes the screen is too dark in relation to the environment and other times the intensity is enought.

E

sometimes it is impossible to answer the call by pressing the green protocol button that appears at the top of the screen. only by unfolding the upper beam and pressing the inscription answer, it is possible to answer the call.

As I wrote before, until a full and clear instruction on how to send logs from the system with an * .txt attachment appears, I will write here. The advantage is that other users can see your reports and communicate with them.
