Lg G3 F400K antenna feature - G3 Q&A, Help & Troubleshooting

I heard the antenna isn't useable outside korea.
but what if somebody hacked it and made an radio app?
btw sorry for my bad english

There's already an FM radio app in the G3, and it uses the headphone as antenna.
I don't think the Korean antenna can be used for this purpose as its frequency is hardcoded.

awhh thats to bad. I thought maybe we could use the antenna for the radio instead the use of a headphone anyway thank you

Radio Murata for Diamond?

Which die hard tried the radio Murata for a better radio?
Mate. do not even try. ok?
Diamond is MSM 7500 platform, while Murata radio is for MSM 7200 platform. no chance, do not even go there. Well.. if you would, mak sure that you know how to un-brick the damned thing.
I am sorry fo being too much straight forward.
I hope it helps
Please do not sorry the fact that you are too much straight forward. i only want to know if its possible to use it and if not, if someone plans to make such tool for the Diamond

I thought the exact same. What a very random thing to say.
An application which makes the radio better like Murata did? Or an modified radio. Simply because everyone has problems with the signal of their GSM.

for that you'll have to wait for HTC.
it is possible it is a hardware limitation (don't know how the antenna is put in) but most probably the 0.93/1.00 radios are just a bit too early releases.
Let's hope for a better release then..the TC and TD are almost the same, so my guess is that it's not the signal for hsdpa or 3g which sucks down the reception.
Wierd but the reception on mine is very good (T-mobile US). Better than my touch or Nokia N78.....
Could you tell me which radio you have, which band you use and if you can use hsdpa etc.?
thank you very much!
1.00.25.03 Radio
1900 mhz on T-mobile

Ah, de EDGE is doing it. If i put my phone on band GSM i have full signal also, but i want my hsdpa ofcourse
I've tested with batterystatus and when the diamond have 1 signal bar it says 46%, 2 signal bar it says 74%...

Bad Reception on 3g....

Diamond is well smartphone,the problem for my experience is reception on 3g is very bad bad,on gsm is good that sam other smartphone,have smartphone asus m530w on 3g is good
Thank for reply
what radio are you using
best bet is to play with other radios and find whats best for you where you are

[Q] Official Gratia cover on Aria Phone & vice versa

Hi, does anybody know if the Gratia and Aria covers are interchangeable?
My wife has an Aria and is happy with it. I was thinking of getting a Gratia, but swapping cases so that she can have a white one on her Aria.
Given the antenna is in the cover and the phones are for different markets I wondering if the antennae might be different? Does anyone know for sure if they are interchangeable?
Thanks
I'm not 100% positive the covers are interchangeable, but I think they are. However, they aren't both compatible with the same wireless networks. You can use them both, but the Gratia won't be 3G in the U.S. because it utilizes different frequencies. It will still get data, but it will be at EDGE speeds.
Yes I realise the phones are for different markets and operate at different frequencies but I'm wondering if that means the antennae are actually different.
I noticed Expansys USA has the Gratia cover listed under accessories for the Aria,
But then what they quote for the Gratia "Mfr Part #:" is 74H01655-11M, whereas HD-Mini is 74H01655-02M (nothing listed for Aria, but I think it is also 74H01655-02M)
I'm only really interested in data in the UK on both devices, as I prefer not to pay bucket loads to the phone company when roaming, but my wife wants a white phone!
There are countless innovations of technology nowadays. There’s a fast pace of technology development even on phones. Some finest innovations of phones today are aria phones from LG and cordless phones. People keep on inventing gadgets on how to make life easier.
Doesn't the antenna just collect the signal? Surely whether it will work on a particular frequency is determined by the radio hardware in the device?
I'm just thinking - an antenna is an antenna isn't it? Same way you can use a coat hanger to pick up FM or even TV transmissions, it's all just about capturing the radio waves right?
I could be miles off base here but I honestly would have thought that the antenna that's built in to the back cover would NOT be specific to a particular GSM frequency.
Would love to know for sure though.

AFAIK, right. If the contacts are in the same place the cover should work quite well.

That's technically not true - GSM antennae are most certainly tuned for particular frequencies - if you look online, you'll see different ones with different specifications, like 850 thru 900, or 1800 or 1900. However, through some trickery, a single antenna can be tuned for more than one frequency at a time.
That being said, I have no idea what the antenna in the back of the Aria or Gratia are tuned for - it's possible they might be dual band specific to the carrier (ATT 850/1900 or Euro 900/2100) or it might be a universal one capable of picking up all 4 or more frequencies.
I'd say best bet is to get one of the other ones, try it out and see. And let us know - I'd considered getting a green one for use in the US...

I hear what you are saying but I think people are confusing the antenna with the GSM radio built in to the phone.
Whether a phone utilizes 850/1900 or 1900/2100 bands would surely be a funtion of the radio in the phone that is hard coded to those frequencies.
Isn't an antenna just "fishing net' that actually gathers the signal?
Again, could be miles off base here, just applying my own brand of common sense.

It really depends on how the antenna was designed. Resonant frequencies are generally a factor...so antenna length could matter. Polarization and radiation patterns are also taken into consideration.
That said, until one has both covers (or finds some internal design docs), it's hard to know if there is any difference.

Unfortunately, common sense doesn't really apply when it comes to signal theory.
I'm not an expert by any means, but from what I remember from a signals course I took a few years ago in college, johdaxx's and M1m3R's posts are both spot on.

Both the Aria and the Gratia work for the 4 bands of GSM, so there's really no problem if such tunning was a factor to consider.
The quality of HTC Support on this was really quite shocking, e.g.
Thank you for contacting HTC regarding the swapping of Back cover. In short to your email. Yes buy [sic] swapping the back plate can have effect on the device's perfomance. Which is why we recommend original products. Mohammed - UK Ireland Support (Tech)

When challenged he came back with:
"It does not matter which cover goes on because the real difference is the internal components."

Then...
"I can confirm that the back cover is just a bit of plastic. If the connectors will allow you to plug the new back cover in then it will work." Jason [UK - Ireland Support (Tech)

When I pointed out there were some metal contacts...
"Those connectors are there so that the phone knows that the back cover is on the phone. It has nothing to do with the signal as the antennas are up the top of the phone. "

I pointed out HTC's own support website says: "the antenna for the HTC Aria ™ is located in the battery cover."
"There is nothing more we can do, as we will be going in circles regarding this matter." Mohammed (again)

idk man, for me that's the typical quality. I dont expect any help from any large company. For example ask any carrier's seller about batteries, they all gonna say you should fully discharge it before charging, like the old batteries. They know nothing.
But, again, both phones uses the same gsm radio freq. The only real change in hardware is the umts radio freq and I'm pretty sure the covers doesnt change cause of that. Hell, every GSM phone has a different antenna solution and they all work with the same quad band freqs
OK Back to to casing now where can u buy a white back for the HTC Aria and know that it'll work, I would love to have a white back on my Aria...
I would love to get a fluorescent green one.....

Weak signal for Korean version F180L

Hello,
I have bought my Korean version of LG Optimus G but I'm living in the Europe and have problems with signal. It is very unstable - in the same place it can be full signal but after a moment it goes down to only one blue line or even without it! That is very frustating because I had normal signal on my previous phone. Can the problem be the fact that I have cut my Mini-SIM card to Micro-SIM? (http://howto.cnet.com/8301-11310_39-57484847-285/how-to-cut-your-own-micro-sim-card/) Maybe I have to install another baseband or ROM to my F180L?
Is there any sollution or suggestion?
Thanks!

I think its a hardware related, fortunately in my case both the hardware and baseband is compatible in my country.

I don't think so. I think that it may be a baseband error. Also the Wi-Fi signal is unstable.

Baseband issue

Hello. I have an unlocked i9195 on CM13 official. I currently live in the north of England, and I use the network called giffgaff (O2). I would like to know if any baseband would do or there are specific ones for these circumstances, like os version, location, network. I have bad signal most of the time. LTE does not work 98% of times, WCDMA around 50% and GSM works almost always. Any suggestions are welcome.
Thanks for your attention.
i am also on Giffgaff in the midlands. i9195LTE
running TWRP 3.0.3.0 , AOKP official rom 20170202 , remix N v0.6 kernel.
baseband I9195XXUCPI1.tar.MD5 [Vodaphone] latest for this phone ( i believe). from sammobile/firmware ( saw thread here XDA about updating Baseband)

I have the latest BTU version of the baseband installed it's from around 2015 been working fine here.
Its probably a coverage issue I recommended trying other carriers to find out which suits your needs best.
I myself am using unlimited data plan on Three, works wonders.

Any should work, though generally it's recommended you keep your ROM and baseband to a similar release date, especially if you are having issues. Are you still on the original baseband?
You should be getting good converge on O2 or are you in a remote hilly area or near some other source of interference?
Else it could be hardware eg damaged component or poor grounding of aerial or pcb to phone ground plane. (cleaning contacts and/or tightening screws may help)

No I am not on the original baseband. I9195XXUCPE1 currently. Regarding the coverage, I checked on their website and the area its pretty well covered for 4G reception, nonetheless I believe there is probably something wrong with the phone itself, I will probably just give up on this phone and spare myself some days of calamity.
Anyways thanks for your reply.

yes, sounds likely that it is hardware. A quick test you could do is pop the back cover off and connect a small wire to the test connector (at bottom level with the speaker) bypassing the actual antenna, if your signal strength improves then it is proof it is your antenna circuit where the problem is or the contacts.
You can also test by pressing down where the "touch" connectors are., see vid, sometimes it improves reception showing it's a bad connection with contacts.
This is often easily fixed by removing the inner cover & cleaning the contacts or applying a little more pressure to them with a little piece of plastic between them and the cover.
You can see from this video that the antenna are simply a "touch" connection to the main assembly.
about 2mins into the vid
should be a cheap fix at a repair shop if you don't fancy trying it yourself, if this is what it is.
