NOTES:

• Don't forget, use bitgapps only, opengapps probably does not work.
• 4 big cpu cores offline is absolutely normal, this is for power savings, the cores will turn on automatically when CPU load is increased.

Is this same as lineage os 16 hyper? I mean is there any other difference?

Clearly, the difference here is that there's VoLTE in this build while Hyper LineageOS does not. Also some other performance optimisations have been added and few drivers in the kernel have been updated.

Thanks so much for keeping this device alive, sorry for the question, do you intend to update it periodically?

I did not know I had to install another type of gapps now my phone does not start and does not hate to delete anything, what do I do now?

You need not to delete anything. Just wipe data and system then proceed to install ROM and bitgapps.

I thought that I am never gonna see volte supported pie ROMs. You did what was seemingly impossible thing. Thank you for your work. Volte works fine but the people on the other end are complaining that they barely hear my voice.
I flashed Android mic fix magisk module still the issue persists.

I managed to fix the problem, the rom seems to be wonderful just did not like it because I could not back up all my google data, on the microphone I have not tested.

I am using it since a week, and not even single freeze. You need to under clock cpu in order to extend battery little more.
