The Pi/e/ test ROM e-0.8-p-20200413-UNOFFICIAL-h850 comes like the official downloads /e/ for h850 dev (nougat) without an analog FM radio app, although the hardware is designed for it. With LG stockROM Android 7.0 & 8.0.0, FM Radio App version 6.20.6 is shipped (Image #4)
Lineage has recently listed it in Device info under Peripherals : FM radio, but has not (yet) implemented it in the current builds. It seems to me that the software features not integrated by Lineage do not appear in the /e/ OS build either.
For testing purposes I installed the software & app FMRadio FM2 Lineage-16/AOSP which works with AOSP Pie ROMs. The screenshot #1 next to the weather app on the bottom right shows the FM Radio icon.
Even though META-INF, AndroidManifest, classes.dex, resources.arsc, etc. is installed next to the FM2.apk, the FM2 app does not work. The reason for this will be that “fmradio.lib” is not enabled in the kernel and “libqcomfm_jni.so” is not located in /system/lib64.
I also found the app in the package list of my buildfolder… i wll try a build with specified fmradio to be build in script, lets see if that changes things…
The much-maligned camera module LG CAM Plus (CBG-700.AEUASVP) does not work with any custom ROM: lineage-17.1-202004* or /e/ dev (nougat) or /e/ OS Test build e-0.8-p-20200413-UNOFFICIAL. Too bad, because the camera takes great pictures with srockROM Oero 8.0.0.
