What do you need to know about an FM radio app?
I remember that the headphone cable serves as an antenna? Does an FM radio app work with the Teracube 2e without the headphone cable?
Which FM radio app can you recommend (for the Teracube 2e)?
Please an APK App.
Hello,
I have the same question. Did you find a answer? What app (withou internet) do you use?
Thank you 
No answer found till this day. 
In the teracube forum also no answer: FM radio wanted (iodé) - #3 by wamodu - Teracube 2e - Teracube Community
I’m the wrong person to contact here.
I’m a pure, albeit enthusiastic, user, but not a member of the iodè team
neither mod, nor admin, nor developer.
It is correct here:

I have no experience with FM-Radio on Android (I use Transistor Internet-Radio App).
But have you tried this: How to Activate an FM Chip on Android: 9 Steps (with Pictures) ?
Apk for this App is found here (I personally never download Apk from such a site): https://m.apkpure.com/nextradio-free-live-fm-radio/com.nextradioapp.nextradio
Have you tried this:
A googd fork of Transistor with more enhancements
Available via f-droid izzy repo
People, please don’t boring the teracube 2e user. This thread is only for real terrestical FM radio and not for radio streams. Please clean the comments from radio stream apps.
Iode must be activate the FM radio chip in the teracube 2e in their ROM. Otherwise, there is no way.
+ a real terrestrical FM radio app.- Contains ads.- no APK, only via Google Store.+ a real terrestrical FM radio app.+ APK.- but this requires an Qualcomm processor (The Teracube 2e has an MediaTek Helio A25).First: it needs an activation of the FM chip in the iode ROM.
Second: it needs a real terrestrical FM radio app.
Please realized it. Almost 1 year has passed now. I had buy the teracube 2e in the iode shop, because it has an terrestrical radio.

Hello @miria ,
If you still search for real terrestrial FM radio apps, you can download SpiritF from F-droid.
Last version is old (2015-04-14), but it starts on my S10e with Iodé 4.15.
The problem is this app requires root. I don’t want to root my phone.
I found a workaround : according to https://www.reddit.com/r/galaxys10/comments/ob43bv/comment/hdrf7hi/,
if app is in system partition it does not require root
With a link to https://www.androidauthority.com/install-user-app-as-system-app-how-to-93522/
that explains how you can use ADB to install an app as a system app without root.
I did not install ADB either. So no FM radio for me yet.
If you decide to give it a try, I’d be curious to know if you managed to listen to FM radios or not. It might hep me take the plunge.
Cobus.
The app is not longer available in F-Droid.
True. 
But it is still available at XDA forums : https://xdaforums.com/t/app-4-4-5-150317-spiritf-spirit2-free-open-source-real-fm-radio-for-aosp-root.2951455/ (end of first post) !
Okay, but, there are secure risk discussed in the internet about this app.
