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.

When challenged he came back with:

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.....

Can anyone tell me if it is possible to change the HTC from a Euro phone to a North American phone by perhaps changing a chip or programming to support 850/1900 here in North America? I live in an area where 1900 is a bit spotty and I lose signal, especially inside buildings. I love my Uni, but I have too many people complaining that I'm not getting their calls and I don't get signal where other's do.
I'm afraid I don't have enough hardware experience to be qualified to even venture a guess. But shouldn't it be as easy as changing a chip or a crystal or something?
It's just a matter of both the range of the tower you're near, as well as possibly your PRL. The priority roaming list tells the phone who's service you're allowed to use. So if there's a tower within range, but not in the PRL, chances are your phone won't use it OR it will show up as roaming.
I know you can affect the 3G part of Android phones by changing the modem firmware when using Odin, and even them I'm not sure what change is made if truly any. I don't have 3g yet with my provider, which uses the 850/1900 as well, but I currently have a Euro firmware on my phone using XW Euro firmware. I'm not sure how it will affect my 3g until my provider enables it.
Other than that, I think it's a limitation of the radio chip in the phone. It may be a firmware/software setting, or it could be hard coded into the chip.. again I'm not sure
Have you seen the previous post date? lol.
Anyway thanks for your reply
Lol, true it's old, but if anyone has a solution I'd accept it. However, I've since moved on with 3 different phones including the PPC6800, the Omnia II and presently on the iPhone 4.
Thanks anyway,

No it is not possible, it´s a hardware related stuff.

you have to change the part which contains the Radio hardware
Since I was a dumb and bought a Tmo TP2 to use on ATT, I was wondering if I could buy the antenna from the ATT version and swap it into my phone. Though I doubt it is, I was curious if this is feasible?
Since both networks are UTMS, not CDMA, and thus use similar frequencies, why, therefore, would you want to disassemble your phone and mess with the antenna system, which should work perfectly well on both networks?
Frankly, it sounds to me like you have a different problem: Your phone is most likely locked to T-Mobile, meaning that it cannot use the AT&T system.
Your problem is therefore contractual, not technological, in nature.
I think the OP was actually asking if he could switch his radio, since the T-Mobile radio will not get 3G speeds on AT&T's network (discussed quite a bit here; do a search).
The answer is no. Although it may be technically possible, it would not be practical. Far easier to just sell your T-Mobile version and by an AT&T one.
Ok yea I guess its the radio. Thought it would be the antenna. Could you please explain the difference. I guess the antenna is solely reception and the radio is what interprets the signal? Is there a broken down pic where you can point out the radio.
I was hoping I could just get this http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=250525496122&ssPageName=ADME:X:RTQ:US:1123
Radio: The electronic hardware used to convert electromagnetic radiation signal (radio waves) into usable electrical impulses to decipher to either data (ones and zeros) or audio (speech, music, etc). May also use software systems to further enhance or aid the deciphering of the received signal.
Antenna: The hardware (often as simple as a long wire, sometimes as complex as an array of directional beam antennae) used to gather said electromagnetic radiation signal, and direct it to the radio electronics hardware.
Hope that helps
Thank you for your replies.
So Im guessing the radio is either expensive to buy or requires to replace the whole motherboard?
Hello!
New user here and well, I was wondering if there's any chance that we'll be able to unlock phone bands in this device!
I also know it's probably still unclear as the phone is still new but another user said in another topic that there might be something considering OPO had some tools to unlock bands! So if anyone knows anything about this issue it'd be great!
I'd love to have B28 available on the OP3!
Thanks!
I'd say the reason of the limited LTE band selection is no other than to reduce costs in the hardware. Every band requires it's own amplifiers so making the devices regional it's an easy way to cut corners and not affecting people much (if they don't travel)

I can understand the reason, but it still seems meh to me.
But who knows, maybe there will be a workaround!
hey, ive been looking at buying an OP3 but did read that band 28 is missing which is used for faster and longer range 4G in australia and also common in the rest of asia & some of europe
weird, in this teardown it says the radio can do band 28 ? maybe its just disabled/unsupported?

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

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.
Hello.
Sorry if this comes from nowhere, but I read a lot here, but post little to none, so I'm doing this because I truly don't know what to do or what is the problem with my device.
The thing is that my device (Galaxy S9 SM-G960F) has a really weird behavior regarding LTE mode: it has decent download speed (around 30-40-ish Mbps in every operator I've tried it), but it has really poor upload speeds (around 0.2-0.5 Mbps in those same operators). It happens in every operator in my country, and in every band (B2, B4, B7), EXCEPT for B28 (APT 700 Mhz). On that band, my phone behaves normally (20-30-ish Mbps in download and 10-14 Mbps in upload). 3G, on the other hand, works extremely well in every operator, giving me speeds around 14 Mbps download and 5-8 Mbps upload.
I've tried everything: downgrading/upgrading the modem firmware, flashing official firmware, changing the CSC to the one that has most bands compatible with my country (Chile), flashing Alexandr firmware, using different operators, etc and the problem persists. I'm beginning to think it has something to do at hardware level.
Does any of you has had these kind of problems before? How did you solve it? If this really is a weird case, does it mean it's probably at hardware level? Is it the modem? Amplifiers? Antennas?
Thanks in advance.
I think its just a case of signal fluctuations or antenna switching in the wrong times, i guess its gonna be like that.
May well be hardware.
Not necessarily the antenna or mobo although it's possible.
On the 10+ if the C port PCB is from the wrong 10+ variant it will have no internet or mobile connection. The parts look identical except for P/N.
Well, aren't you full of information.
But yes, he is correct. But I wouldn't like that to be true lest he has to give it in for repair.

It could be. I bought this as a refurbished phone and I don't know what parts they used to make it. To be sure though, I ordered a connector PCB from aliexpress (they were cheap...like US$9) that has the antenna amplifier and stuff just to be sure its not the motherboard (which costs a lot more than 9 bucks).
I'll be updating if I have any news regarding my issue. Does any of you have experienced something similar?
Well, my iPhone keeps fluctuating from 1 bar to 2 bars to 3 bars sometimes.
So who knows? ¯\_(ツ)_/¯

Just what I saw on my 10+ when the wrong variant killed the mobile connection.
It charged A-OK though
Hopefully that will get it... doesn't hurt to have a parts queen for spare parts if you really like that model.

Update: opened my phone, checked everything, even the amplifier board (the one that also has the charging flex) and couldn't see any damage. I'm about to throw the towel on this one and send it to a technician, though I highly doubt it will have any spare part, since this is a G960F and in my country, the model sold is the G9600.
Last time I make a mistake this big on Aliexpress. lol.
