Please explain your issue in details. Like how it worked on stock rom and whats not working in this rom....
The problem with headset volume buttons is that in stock ROM works as expected. I mean it turns the volume up and down when pressed.
In this ROM the up/dpwn buttons acts as a click on the first item in a list. I mean If you are in settings>security and press the up/or down volume button, it selects the first item -Google Play protect- and if you press again it enters in that option.
Of course, I've tried not only one but three different headsets and they work fine in other phones.
This same behavior happens in another AOSP based ROM, so is not related only to this one.
There is also another strange issue with SIM 2: If you turn off that SIM, sometimes is set to on after you shut down the phone. This doesn't happens if you reboot the phone. Similar behavior on another AOSP ROM, althouhg in that ROM it seems to happens always..
I'm not rooted. If you need some other information or logcats, don't hesitate to ask me.
Apart from this, I'm impressed with the options available and overall performance. FOD works like a charm. I'll check battery drain during this next days.
Thks for your work
