Are anyone getting complaining on phone calls about too much background noise? Perhaps the noise cancellation mic is not working, but I don't know how to test it (pls tell me if there is how to).

In fact noise reduction mic (that one on the back) is not working. I've got another call and complaining about noise, and covering that mic with my finger didn't show any change on background noise.
Did anyone reported this before? Is there any workaround or aokp version with mic working?

Is it needed to toggle off-on 'enhanced 4g mode' in settings to enable voLTE on every reboot to get it work or does it work straightaway?

If you search for enhancement in settings it will be there in search results but it will not be available if you select that. Calls are not connecting

Is f2fs recommended for external storage too?

No, if you use external sd card as probable storage because if so, your Windows PC won't read that file system, idk about Linux,

And if you use SD card as internal, it probably when you boot up Android it will again ask you to format SD as internal, this may be changed back to ext4.

Idk I didn't tested but this should be result

I noticed that the volume for headphones has slightly decreased. Even at max I get a really low output, lower than this I can barely hear the music. Is there a way to fix this? The only I know is by installing viper, which overloads the output.
Edit: Intalled Viper here, it is working great now.

    [ROM][OFFICIAL][7.1/8.1][A6020] AOKP-ROM - Lenovo Vibe K5/K5 Plus | OMS/Substratum, ROM for the Android General

    Source Code: https://github.com/AOKP/device_lenovo_A6020

    ROM OS Version: 8.x Oreo
    ROM Kernel: Linux 3.10.x
    ROM Firmware Required: TWRP 3 Recovery
    Based On: AOKP

    Version Information
    Status: Nightly

    AOKP Gerrit: http://gerrit.aokp.co/#/q/status:merged

    This ROM now implements OMS.

    What is OMS ?
    OMS: (Overlay Manager Service) was designed by google. It's a layer/theme service which is used by Substratum: https://play.google.com/store/apps/details?id=projekt.substratum&hl=fr

    So basically, if you install Substratum, you will be able to apply any theme on the ROM UI because OMS has been implemented.

    For the record, on PAC MM or AOKP MM, they were using CyanogenMod Theme Engine for theming the UI, but since CMTE has not been implemented for Nougat, many choose to use OMS & Substratum instead.

    AOKP Oreo (8.1) is now official for this device.

    Big thanks again to @Harry8242 and his great development and contribution !

    Hello guys,

    Here we go for Official Nightly builds made by AOKP Buildbot : https://basketbuild.com/devs/aokp/A6020

    Enjoy !
    Finaly I could install this ROM. This is what I found for now. Maybe some of them was already listed, but anyway, there are:

    1. Shotcuts on lock screen desapear from nothing, the top ones or the righ bottom;
    2. Alarm icon and some others desappears after reboot, and after re-enable them appears a blank space at right of battery icon;
    3. Notification led don't turns green when fully charged;
    4. Notification led don't stay lit, it always pulse even if I disable this on settings. I uncheck this, go back, and if I return to this setting, it is re-enabled itself. I have to add personalized led notification to each app I want to keep always lit;
    5. I don't have a warning telling an alarm is next, like PAC-ROM;
    6. "Don't disturb" (or "Do not perturb") keep some sounds even it is enable only priority alarms. As well, the icon for schedule time for "do not perturb" is different for manual "do not perturb" (from the status bar pull down menu): the scheduled is a "plus" sign, the other is a "minus". Can anyone tell the difference or how to have always "minus" scheduled, please?
    7. Some calls still alive after some seconds even when I terminate them;
    8. I use a PIN for lock my phone. If I configure a direct call to lock screen, it dials the number directly, don't asking for PIN. Any other shortcut ask for PIN;
    9. I can't find the icon to change the screen off timer on status bar pull down menu. I have to go to settings to change this timer;
    10. How I can 'centralize' the listings? They always appears at bottom of screen;
    11. Date and time aren't correct after a reboot. I have to keep automatic date and time from network in settings;
    12. After a reboot, battery mode is always at 'balanced', even if I configure to 'performance'.

    Other issues:
    1. I haved to use TWRP R2 instead R4, because R4 shows two 'data' partitions. With this, R4 always returns erros about can't mount or format data;
    2. System is very low in free space, so I used TWRP R2 to backup the whole ROM, and just after I restored it, like sayed before. I gain about 1,2Gb of free space, and can move some user apps to system partition;
    3. There are translation errors, at least for brazilian portuguese: a lot of words are still in English.

    Even with these, the ROM is the best I used until now. Is really fast, camera works fine, and there a lot of options to personalize. Very, very thanks for the ROM.

    I'm using 12-12-2016 build on a L36 variant.

    Thx for this great and detailed feedback.
    I made a new build today, with somes fixes, let me know how it's going:
    * Fixed system and other partitions size, so you should be able to flash micro or mini Gapps for example now.
    * Added the LiveDisplay in the kernel
    * Divided light sensor returned value by 10 this is much much closer to what we get from the Moto G4 Plus sensor
    * xxhdpi density (tks to Dinokin)
    * Tethering should be fixed
