I was reading this http://www.droid-life.com/2011/08/2...ail&utm_campaign=Feed:+DroidLife+(droid+life) and took a closer look at the specs when I noticed that is says the Charge has FM Radio. I know I can stream FM Radio from the Internet but that is not the same as an FM Radio.
If its not a mistake, then it is news to me also, but I'm sure its a mistake

alright first off before i ask my question i think all of you should know. i am an extreme newb to cell phone hacking and moding so please excuse my arrogance 2nd thing i do most off my posts off my cell phone so please excuse the bad grammer and spelling. anyways as i have been reading in the forum people list the mods to their phones and i notice one listed radio? so could someone educate me on what a radio is i figure that it is what keeps you conected to the service provider but other than that i am clueless so when you mode it do you physically open the device and replace something and 2 what is the point of changing the radio do. so could an expert educate me and feel free to tell me everything you know rather than just answering my 2 main questions.
I guess thats its the radio you use to listen to music, news etc... Most phones nowadays come equipped with built-in radio function. I hope that helps. =)
im not too sure about the exact thing you are talking about
however thats what a buddy of mine working in a cell repair shop told
for the radio(the one that broadcast phone signal not the radio you listen to)
you know that in order to use a 3g phone in the US or elsewhere
[but the problem is mainly US cuz here we use special 3G band compared to the rest of the world] you need to get the good frequency
however most of the time manufacturers only design and produce different radio chip for different region if they really have to
cuz you know running those factories is not given to anyone
and why redesign a phone when you already have one
a phone is like a computer.. "change a part, gotta change the whole part" concept..
however a phone might not work in certain 3G frequencies not because the radio cant but because the manufacturer didnt pass the regulations in those regions and it happen that the phone can be 3G but its locked in the ROM
so you need to mod the ROM to make 3G radio work
like the omnia
some ppl argues that it might be dual-UMTS but the US 3G is locked in the ROM
because samsung didnt pass the FCC(Federal C??? C?? the agency that rules communication) at that time(when the first omnia shipped)
so they couldnt put US 3G
same thing for the touch diamond but it was GSM that needed to be rom-unlocked

This is what i understand about radios (the cell phone kind )
Your radio is what communicates with the tower and can affect how many "bars" you get. Not having the correct radio will also cause your phone
Camera not to work, to have a black screen, and/or to have no sound or intermittent sound.
The radio chip stores information, but you can change the information on that chip by "flashing a new radio."
This is just my own understanding so if i made a mistake don't be afraid to correct me
I believe the radio part of these devices is the information that tells the hardware in the phone how to act. What frequencies to use on the cell band, how the wifi antenna acts, how the bluetooth antenna acts, etc... Even how the GPS antenna works. Hence while in CDMA land my Titan needed a GPS enabled radio to make the gps work. There was a chip and antenna in there, but the radio excluded directions for the processor to interact with it.
My mind is simple, and this may be wrong but it is how I understand how the radio portion affects the phone.
Also, feel free to correct us if we are wrong!
Wow... Where.... wow.
Radio function
Radio is the whole function of the cell phone part of your tiny portable PCs your carrying around.
Its a
Duplex (transmits and receives separate carrier waves at the same time) ,Two-way, VHF and UHF, FM tranceiver in its purest form.
The cell towers are nothing more than ham radio pioneered "repeater" stations, connected to land phone lines. 20 years before the 1st commercial cell phone, HAM radio operators were setting up their own area "club" repeater stations, and networking them much like cell phone operators do now. The biggest rush of my young electronic life was carrying a kenwood TR-2500 FM handheld with me on my Yamaha YZ-80 out to the remote areas of our trails, and making a phone-patch call from the handheld thru the repeater and to a household phone. It felt like star trek man. I felt so high tech and up to date as a 15 year old carrying a radio my license didnt allow yet. LOL The funny part was everyone who was on frequency would get to hear your conversation too. Modern cell phones are the same thing only with collars and leashes.
So , back to the PDA with a two meter radio crammed tight agaist a computer with buttons that are too small ...
Thats really what you have.
Everything that a PDA is , outside of Radio [ a patch(voice) connect or a modem(data) connect] is just a small computer.
By the way, I raised the room temp tonite by leaving a Touch Pro turned on and Idling its data connection ...
Circuit... great explanation! But how do I know what Radio version my X1i needs?
In Smartphones and Pocket PCs, 'Radio' refers to the RIL. Radio Interface Layer. An API (Application Program Interface) that sits between Windows Mobile and the hardware driving the phone. An API is a published series of functions/methods that an application or operating system can call.
Ther is a patent for it at http://www.patentstorm.us/patents/6826762.html.
It is so that the transmitter/receiver sits at arms length from WM or its apps, i.e. you can't go POKE the phone's registers directly, you have to ask pretty please through the API.
The Radio part of the ROM is the version that this API is at, for your device.
hello...m gonna flash my fuze for the 1st time and i just hard spl'd it i wanted to know whats the use of the radio?is it important?i got at&t
The radio determines how the broadcast antennae is managed, affects reception quality and battery life mostly. If you're satisfied with those things right now, I suggest you leave it as it, otherwise consult the radio sticky in the ROM section.
Hello
I have a German T-Mobile branded Touch Pro 2 which has been flashed to the WWE rom (1.86.401.0 build 67102), radio 4.49.25.17, protocol 61.44tc.25.32U.
I seem to be suffering from lousy bluetooth and wifi reception and was wondering if anyone else has had any problems,
For the bluetooth, it will struggle to work with a headset that is more than 3-5 feet away. For the wifi, it will struggle if it is more than 4-5m from the access point (with line of sight).
This is really really poor and I'm wondering if my unit is defective or whether they are all like this?
If it's a problem just with my one, does anyone know what the problem could be? I've seen a disassembly guide, which shows that the antenna module is at the top of the device and is relatively easily removed/replaced. Could it be a bad connection to the wifi/bluetooth antenna? The GSM/3G coverage is fine.
Any help appreciated.
Thanks,
Andrew
I have the same situation with my phone.
Mine is a US unlocked Touch Pro2 flashed with the WWE rom (2.07.401.1 build 80303), radio 4.49.25.88, protocol 61.44tc.25.33U.
Any suggestion?
I broke the screen on my old phone recently and bought a new Touch Pro 2. The new one is fine in terms of reception, so I imagine the first one (and possibly your one) are faulty. If you have the opportunity to return yours and swap it, I'd do so.
I'm going to take the old one apart to replace the screen. If I find out what's wrong with the reception along the way I'll let you know. I suspect the aerial is not properly seated/connected on the contacts on the motherboard.

I have tried to troubleshoot my issue thinkin it could be my Altec headset. I paired it with my buddies phone "HTC Epic" and has clear connection for over 80 ft. Not the headset. I can't tell what it could be.
I have an EVO running Calkulin's EViO 2 ROM v1.2
Maybe its not that but not sure if its the Kernal or what.
My Wifi connections rock.
I just picked up a T-Mobile S7 to play around with and, as you all know, the G930T on T-Mobile USA has FM radio enabled.
However I've noticed that the radio reception is absolutely horrible with a lot of static, crosstalk from other stations, and dropouts. I tried two other FM-supporting phones that I have (Verizon Moto G and unlocked Xperia Z5 compact) and they're both clear as day with no issues. Note that this is in the same location, with same headphones, and same station... just a different phone.
Does anyone know of any fixes for this? Is it a chipset issue, build issue, software issue?

It could be anything from a faulty component -such as a bad rf amplifier circuit- to an implemented chip/circuitry revision, to a change in component suppliers. If you just purchased the S7 and are under warranty I would exchange it for another one to see if the FM broadcast receiver sensitivity is better. I know there was a big problem with the FM receiver sensitivity on the 930U model devices. I went through several of those and they all demonstrated the kind of horrible reception that you've described. Whereas each of the 930Ps and 935Ps (Sprint model) I've used have demonstrated wonderful FM reception.
Does the Verizon SM-S908U have the necessary hardware/software to receive over the air FM radio reception?
This device does not have an FM radio, sadly. However, now that TuneIn offers local radio stations, it is somewhat of a replacement though it does use up cellular data.
Use Radio Garden and Wrat 95.9
