For following two reason's

1. Either you are in roaming and data roaming disabled.

There no FM radio on CM12.1

What I do to have FM radio?
[Samsung Galaxy Core Prime ROMs, Kernels, Recoverie] AtomR:
Nothing. You've to live without it if you're on CM12.1.
[Samsung Galaxy Core Prime ROMs, Kernels, Recoverie] Girouette:
Hello,

I have been trying your rom for a few hours now, and here are some problems that I found:

- When I tried using root mode in file manager, the app froze.

- I got the bluetooth problem when I turned on bluetooth from quick setting panel, expanded it and open bluetooth setting. After that, bluetooth wouldn't turn on unless I restart the phone, and if I turn off bluetooth, the problem returns. So I replaced the libbt-vendor.so file with your file (and fixed its permissions, ofcourse) and it kinda broke the UI: The status bar turned black and wouldn't display some notifications, the notification and quick setting pulldown background turned pitch black whenever I pulled it down, and in the recent panel, the only the name part of the cards was visible, whereas the preview part was invisible. At first, I thought it was a problem with the theme engine, but after reinstalling one by one, I found out that it was the libbbt-vendor.so file.

Also, I think that an fm radio app would be very much appreciated, because I believe not all of us have unlimited data or access to wifi for online streaming, and that this app could be very important in many situations, like natural disaster, for example. I have tried apps like spirit fm but none of them works. I don't know if it helps, but I have seen fm radio app on other CM 12.1 rom before, on JustArchi's CM 12.1 for Xperia M. Speaking of which, I also think you should consider implement JustArchi's optimizations for CM 12. If it could work wonders on my friend's Xperia M, I think it would benefit this rom a lot.
[Samsung Galaxy Core Prime ROMs, Kernels, Recoverie] Girouette:
Here are 2 screenshots of my phone to demonstrate the problem from the libbt.vendor.so file. As you can see, the phone was connected to my laptop but there's no icon on the status bar. The lockscreen is also screwed up.
[Samsung Galaxy Core Prime ROMs, Kernels, Recoverie] doesntexits:
The blacked-out lock screen, actually it was caused by using "ro.config.low_ram=true" flag in build.prop. Remove it or change the boolean value to "false"

Second, FM app never exist in CM12.1, but we got it in CM13. The reason you saw an FM app in other ROMs was the developer implements themselves, if the SoC supports FM radio feature. Here in our stock, Sammy use frameworks jars for it, which is very hard for me because I don't have any knowledge at Java, just C/C++, so if you want to use FM, get a 3rd-party app for it

And about JustArchi's Optimization, well it makes the ROM fails to boot, that's why I don't implement it
[Samsung Galaxy Core Prime ROMs, Kernels, Recoverie] Girouette:
It works! Yay! :D

See, as I mentioned above, I have tried 3rd-party apps but none of them works. But if CM 13 have it, then I simply cannot wait for a stable build.

That's unfortunate, I guess. Is there no other way to make it work, to make it fit this device?

There's some hope lol. I know a bit of Java (still studying). I could take a look and try porting FM, if someone posts stock framework.jar, /system/lib/libfmjni.so, system/lib/libfmcust.so, fmradio.apk, fmradio.odex.

other files could be required idk. I have to look into it and then ask.

I am on cm 13 so I don't have stock files.

This is .apk file and .odex file

[Samsung Galaxy Core Prime ROMs, Kernels, Recoverie] Girouette:
I have encountered a few more problems:

- Changing theme with the theme engine make the phone stuck at boot animation when reboot. Also, changing the bootanimation.zip make the boot animation disappear completely. But I think someone already mentioned this.

- Whenever I reinstall the rom, there is always a shortcut for screencast on the quick settings panel. However, when I go to Setting to rearrange them, there is no screencast shortcut in setting, and if a shortcut is moved, the screencast shortcut will just disappear and can not be found anywhere, and after that, the shortcuts just won't display correctly around the position where the screencast shortcut used to be.

How can I restore Samsung memo's memos

What I have > TWRP BACKUP

What I did trying >

1-extracted the app and the data

2-added the app in system app folder and rebooted (I know it need libs / odex in folders but at least tried

3-after reboot it installed but as expected "memo has stopped"

4-moved the data to data/data folder (more silly step) and still stop

[Samsung Galaxy Core Prime ROMs, Kernels, Recoverie] rms112:
You probably won't be able to restore memo because that was for 4.4.4. Your best bet is to look in the data and open any database files .dB or whatever file memo writes to like XML etc and copy the notes. if not install stock then copy the notes to another app.

You can provide me the data files zip and I will help you restore them into plain text files. Please note that if you've set password, your files would be encrypted and I cant do anything. You should use stock rom in that case.
