I can use any headphones as radio antenna? - Optimus 7 General

I got this phone a few weeks ago and I think I discovered something special.
A few days ago I was listening to my songs on Zune using my iPod earphones when I accidentally touched the Radio button and it started scanning and playing the radio, I was shocked, I went home and tried other earphones that I've had and it all works as the antenna, without using LG's earphones.
Does it happen to you all?

Yes. Any headphones will work as the antenna.

Actually, even if you use a 3.5mm headphone jack without any actual drivers (ie, the things that make sound) on it, it will STILL work as antenna. Remember, you can switch the radio to play through the speakers though.

Regular headphones on HD2?

Will a regular earphone work on the HD2. I hate the ones that comes with the unit and would love to use my noise canceling earphones.
I don't care about making calls with the earphones. I just want to listen to the FM radio / music with it.
Since it's got connectors to control the calls, I didn't want to short out my HD2. I searched and found a thread about someone's HD2 reseting everytime the plug in an adapter to the headphone jack. He said it works for other MP3 players, but as soon as he plugs it into the HD2, it resets the Unit and will not function.
i use my ipod earphone to listen to my device
like youtube vids and FM radio
yea, i use sony headphones fine
regular wired headphones will do fine, however i dont know about anyone else, but i can't use the phone mic in calls, i have to unplug the earphones to answer calls.
Okay, thanks. I'm going to give it a shot.

FM Radio & Bluetooth

I have cause to use the FM radio but listen with a bluetooth A2DP headset. The bluetooth headset says it is connected for media and phone audio. However, the FM radio audio does not get redirected. How do I enable this? Is there an alternate FM radio app that will direct the sound to the bluetooth headset?
And before you guys jump on it, yes in fact there is a cable attached to the headphone jack for antenna. I just don't want to have to use a wired headphone to listen.
little background:
I like to listen to a particular radio station while I ride my bike. I also like to use my phone's GPS feature with a bicycle computer app while it is mounted to the stem on the bike. So it is terribly inconvenient to have a cable running from my ears to the phone while it is mounted on the bike. I built an antenna cable for the phone that connects to the stem cap bolt on the bike, using the bike's steel fork as an antenna. It works brilliantly with the phone's FM radio set to "Speaker", but when you set it to "headset", it doesn't redirect the sound to the bluetooth headset.
It seems too me that the phone is thinking (yes, thinking lol) that it has a headset plugged in and is trying too out put the audio via the headphone port... I kind of know how you feel because wires while riding a bike is quite cumbersome. It clearly seems like an overlooked problem, but most definitely can be fixed via software. I've been looking at bluetooth headsets for a while now, and this seems relavant to my interests... Good luck...

How to listen to FM radio using loadspeaker?

Good afternoon
I have been pulling my hair out over this for a bit.... basically i cannot get my Defy to play the FM radio out of the loadspeaker! When i access the media app in homescreen 2 on the right, it plays radio flawlessly, however i like to listen to it via loadspeaker until i sleep. There is a button for the headphones, i have tried pressing this and it turns off the headphones, if i increase the volume after this it just tells me the ringer volume is going up!
Any ideas?
Am i missing the blatently obvious?
Am i a useless freak?
Am i mildly insane?
any help advice suggestions greatly appreciated
Thanx!

Calm, calm... it's not your fault. The radio won't work without the headphones being jacked-in because they act as the antenna. I believe this is the reason.

Yep. Smartphones don't have a built in FM antenna (none I'm aware of anyway) so yeah...unless you are under the broadcast tower you don't have much of a chance of getting any stations.
I have the touch pro which has the same issue. I think someone could likely make a hack to use the speaker, but you would still have to have the antenna present.
Hi guys... thanx but I don't think you are quite understanding my issue . I have the heaDphones plugged in to get reception, however I would like to play the radio through the loudspeaker...whilst leaving the headphones plugged in I could do this with my nokia 5800

When you plug in the headphones it MUTES the main speaker. I think it's a physical thing. I don't think there's an app that can over come it. Unless you've listened to some other source that plays through the main speaker with the headphones also plugged in -- then there should be a way to over-come it. According to a Motorola tech the radio's designed to turn off when the headphones are removed.
ahh!
so it is simply not possible with stock firmware... i shall investigate how to overcome this

Actually I'm just saying I don't know how to do it. But if it's a mechanical connection then I'm not sure any firmware would make it work.
You could try toggleheadset widget from here:
http://code.google.com/p/toggleheadset2/ or the original version http://code.google.com/p/toggleheadset/
It is on the Android market but you have to pay for it.
It was originally developed for the G1 because sometimes it was not recognising that the headset was plugged in. It enables you to toggle between headset and earphones. I had the same problem on my Hero. Although it says it is for Android 1.6, I had it working on a 2.1 rom, but don't blame me if it blows your device up!
crazy
thats retarded of motorola, the stock radio app should have a button to switch the audio from earphone to speaker-phone.
An alternate solution, if you have a good data plan or reliable wi-fi by your bedside, is to just stream the same station over the Internet. Get XiiaLite from the Market and queue up your favourite streaming station. You can set a timer from within the app to turn off after a specified number of minutes or even to fade out slowly.
Very clumsy but incredibly complete is "Radio Time", which Sonos uses as their radio source. It's streaming though.
There's an app on the market called "Sound route switcher." Anyone try that?

Instead of using the headphones as an antenna, you could try using an FM antenna wire like the ones that came with car navi's. It has four seperate sections at the mini jack; it uses the headphone slot on my navi and does not switch off the main speaker of it (probably bridges the contacts that are unbridged by a headphone three piece jack).
Cannot try it here; I have the antenna but no Defy here.

Actually it`s not a physical thing, it can be routed via software to the headphone or the speaker, you can test it by connecting the headphones and them calling to your phone, it will ring through the speakers not the headphone. The Milestone have a standalone radio app and let you hear fm radio through the speaker.
FM Radio loudspeaker fix
I installed a FMRadio.apk on my T-Mo US Defy and it works fine. Just copy to root of SD card and use Astro File Manager to install. Loudspeaker works fine with headphones plugged in. Hope it helps.

Confirm with 2.2 Pays-ROM
Also since it's possible send audio on loudspeaker may it be possible route it on BT headsed?
More than that - there a lot of phones with radio (samsung, for example) which have built-in radio works with earphones plugged in, and i've used pathces on their firmwares to make radio works WITHOUT headset. Ant it worked. @City with good signal, at least.
I too am interested in this, routing audio through my bluetooth headset could be achieved on a Nokia E51, is it possible to do the same thing on Android?
As I known - FM Radio Speaker is an easy-to-use tool that can turn on the speaker to play when the headphones are inserted.

[Q] Bluetooth headphone connection to DVP

When I use my sony MW600 bluetooth headphone connect to DVP, I found it worked on dial,answer and enjoy the music. However, when i turn to viedo the sounds came out from the phone, and back to music the bluetooth headphone work again.
Does any body have the problem with it?
Its a WP7 problem, audio from videos is not sent via A2DP. We dont know yet if it will be marked as a feature never to be changed or identified as a bug and fixed in the future.

This bothered the hell outta me. I have the Sony DR-BT21 and DR-BT101's and I loved the sound quality that I got out of the phone with either of them. When it came to video, I realized Bluetooth audio playback for video was a limitation of WP7 rather quickly and I ended up carrying the stock headphones whenever I wanted to watch a video from BitBop and Netflix.
The solution I came up with was to buy a Nokia BH-905i. Definitely not the cheapest pair of Stereo Bluetooth Headphones you can buy (MSRP is ~249.99-299.99, I got them from Amazon *using the WP7 app* for $179), but there is a 2.5 to 3.5 cable that comes with it (actually two, one's for the iPhone) that will still allow you to use the Active Noise Canceling (ANC for short) and not switch headphones.
Pros: 25Hr BT Battery Life; 13 if you have the ANC on
Con/Trade-off: No FF/Rew/Play functionality when plugged into the 2.5mm.
Interesting bonuses: You can charge your headphones AND listen to music; Even if the battery died, you can still use the headphones with the 2.5mm Jack WITH ANC for 15 hours!
I had a pair of Motorola BT Headphones about 3 years ago that were cheaper (think $50 to $75) and wrap-around your neck and also featured a male 2.5mm jack. If I come across it again I'll post the model number for you/anyone else that's interested.
Hope it helps.

Here are the headphones I mentioned, I hope this helps.

FM Radio works fine over Bluetooth headset

I know this is going to sound stupid, but I wanted to listen to FM Radio on the Moto G using my bluetooth stereo headset.
I took an old earphon and just cut it, leaving about 8 inches hanging from the audio jack. It worked fine as an antenna.
For some odd reason, my Bluetooth headset wasn't getting any audio from the FM Radio app. I started another audio app and played a MP3. Then the audio from the FM Radio started getting mixed with the MP3. I closed the MP3 and then the radio played fine.

Can you elaborate on the exact steps and software you are using to get this to work? I've connected external headphones/speakers to my audio jack to act as an antenna, starter the FM app, then started another MP3 playing app (Apollo, poweramp, Google Music) and cannot get the 'mixing' affect you are describing. Am using 4.4.2.
The only revolutionary thing I've discovered is I can use the Google Play "HF Button" to route the FM radio out the moto g speaker rather than external headphones.
Would love to get FM radio routed out my bluetooth headphones.
I want the moderator to ban me.
