@andr68rus Could you fix 1)the sim change after reboot. I can't turn on data unless I go to settings and do it manually by selecting data over "ask for permission"
2)on aggressive idle, system terminates white listed apps too.


EDIT: After reboot, both Wi-Fi and data don't activate from notification titles. And on-call sound is really low.
++ Wi-Fi can't connect it says connecting and then the network gets tagged as "disabled".

If I understand correctly, the BaikalOS installation should be as follows:
1-we put on the phone: LEX820 (X2_CN) 20s, rom Baikal, TWRP, GApps and Magisk
2-reboot: install new TWRP, then LEX820 (X2_CN) 20s
3-wipe
4-Flash ROM BaikalOS and GApps
5-Reboot to ROM and finish setup
You can not install this rom directly on the installed lineage, aex or pixel. Does the phone have to be treble.

Must be trebelized, the phone must have the vendor-partition.

Battery rock solid like frozen Baikal ?! :D.
Edit: Installed. Any way to remove the headband "search" bar other than using another launcher?
Battery power saving is not finished yet as we want it to work :) But soon it will be best :)
I will work on stock launcher soon, this is in ToDo. But as for me stock aosp launcher is has very weak functionality in compare it with for example Nova. And no profit to using it at all - it no faster, no less battery. But thats IMHO :)

Could make out what you mentioned about battery. At present moved back to Nitrogen where I get close to 5 hours SOT with mixed usage. The attached screen shot from Nitrogen 12/01 is my usage with only few secs for GPS, good amount of browsing and rest my daily mixed bag.

    Sorry man, but from all which You wrote until now, 100 times ask one the same question about SoT and bilions request to colleagues to give You screenshots about that, but in same time You do not want to test roms and check it by Yourself and choose what is the best for You, only logical conclusion is, You are not exactly normal human, some problem exist.
    Please do not spam here anymore !
    I appeal to admins and mods to keep and save us from this !!!
