OK so I've tried this after trying another ROM on this forum called 'Potato OS/ASOP'.
- LinageOS boots quicker.
- Phone proximity/camera sensor works for phone calls (the other one didn't).
- LinageOS takes less RAM. Phone uses 1.7GB at idle Potato takes up 2.1GB at idle.

This is gonna be my new daily driver! Thanks so much for posting and updating these (and thanks to Lenny Bard for making it a bit easier to find the latest version of LinageOS for the A40 :)

I have been using the latest build, but I am having some issues:
- The phone behaves weirdly when charging. Sometimes unresponsive to buttons push, touch... Have to unplug it and reboot it to get it back working.
- Sometimes the wifi will disconnect, and will fail to connect back to any wifi. A reboot fixes it.

Anybody else?

I'm not seeing any contacts from my Google Account. Anyone else have this issue? Is everyone using NikGapps with this?

EDIT (I found the answer):
I found how to fix missing contacts. This fix is descripted in the FAQ (i'm including the link as other fixes you are likely to run into are included here)

Does anyone have issues with the top of the phone screen staying activated when the screen is off such as during a phone call? My face keeps dragging down the notification area and I keep putting people on hold haha.

Heads up. The latest build (as of this post) called "lineage-18.1-plus-20210709_122105-UNOFFICIAL-c8a2e8a-a40" doesn't work and results in it getting stuck at boot (SAMSUNG Galaxy A40 logo screen).

Here's the firmware file I used:
SM-A405FN_BTU_A405FNXXU3CUC4_A405FNOXM3CUC4_A405FNXXU3CUC2_A405FNXXU3CUC4

I tried to install versions:
18.0-20201017
18.1-20210327
18.1-20210510

All wont work. I dont even see the lineage start up thingy.
Only one that works is 18.1-plus-20210723, lineage will start, everything works. But i have NO SIM. A phone without working sim is not handy ofcourse. Any ideas to get sim or other versions working?

(or other custom rom without all google trash, i like lineage though)

    LineageOS is a free, community built, aftermarket firmware distribution of Android 9, which is designed to increase performance and reliability over stock Android for your device.

    LineageOS is based on the Android Open Source Project with extra contributions from many people within the Android community. It can be used without any need to have any Google application installed. Linked below is a package that has come from another Android project that restore the Google parts. LineageOS does still include various hardware-specific code, which is also slowly being open-sourced anyway.

    All the source code for LineageOS is available in the LineageOS Github repo. And if you would like to contribute to LineageOS, please visit out Gerrit Code Review.
