AT&T 3G resolution - Ideos S7 General

Okay, so I've been trying to figure this out.
When I get the tablet, I was in Florida, and the 3G worked fine. No problems whatsoever. Now that I get to my home in the NYC area, the 3G doesn't work at all.
I've tested with 3 different AT&T sims and 2 different S7 tablets.
Here's what I found out.
Edge works. Edge will always work. The device has no problem initializing with the connection with the cell tower when GSM Only is set. After the device has initialized with the cell tower and has signal (Settings > Status > Mobile network state: Connected), you can switch to WCDMA (3G bands)
Data will work, but dialing out will not. This is because voice is a different channel than radio on 3G.
But if you remember, I said it worked in Florida. I believe this is because, in Florida, I probably didn't have HSPA (3.5G). I only had UMTS (3G). I have tried to disable hspa and try to get it to work on 3G only, but I haven't found a way.
Are there any AT&T users on 3G that would like to report their findings?

I replied to you a while ago over on androidtablets.net - but have you tried the Indonesian Froyo update? It includes a radio (baseband) update, which seems to have fixed all of the 3G problems I was having before.

3G on and Off

So, i have bugged folks on this forum about getting 3G to work on other carriers, and it turns out - it does work! At first i found out my settings were set to GSM only, but now i also found this weird inconsistency possibly a bug.
If i have Data Off after using 3G or GPRS for some time, when i turn it back on, phone would not connect to data service. After enabling it will simply time out.
I found that if i switch from GSM to WCDMA, and than back, 3G network would connect and work.
I don't know if it's specifically my phone, or a bug, so i'm just throwing it out there.

What carrier are you getting 3G to work? I doubt its working if its anything that doesn't run on tmobiles bands..the icon will come up and stuff but your either getting edge speeds or not getting any connection. I've had this phone show me 3G with full bars and just time out.. I can eveven put in a sim with a sidekick plan or other data plan and it shows 3G but it does not work
Well, i'm overseas and i have used it on Russian carrier Beeline and carriers in two other countries. Now, i do set my connection to WCDMA only, which gives me 3G icon. When i set it to GSM only, i see GPRS icon show up.
So, it does work, i use fring, online radio, google maps. But as far as speed concerned, i have not tested it.
Just ran a speed test using Speedtest.net tool, I get 3951kbps download, and 655 upload
thats 3G

Can a Canadian SGS be put to 2G?

I heard that sometimes switching to 2G has given some people better reception in certain areas. Can I do this on my Samsung Vibrant (Bell Mobility)? I don't see the option in the menu
The Bell Galaxy S unfortunately cannot be put into 2g mode on Bell's network, and here is why:
Bell's current 3g/HSDPA network uses GSM cell technology, enabling SIM devices such as the Galaxy S and IPhone to work on it's network. Prior to launching this network Bell used a CDMA network similar to Verizon and Sprint in the states. Bell launched their new GSM network in order to be able to get the newest phones and stay competitive with Rogers. Because Bell's 1g and 2g networks are CDMA based they are not compatible with the GSM radio chip in the Galaxy S. This is why newer Bell phones have SIM cards but older ones do not.
If the option to use 2g networks were there (and it was in my original Bell Galaxy i7500) you would completely disconnect from the cellular network if you enabled it. The option is available on Rogers Android phones and does work as Rogers has a 1g/2g GSM network that the phone can fall back on.
This isn't much of a problem in urban centres (and most places in Southern Ontario) as Bell's 3G network is quite large and reliable. You may run into trouble in rural areas where Bell may not have upgraded their towers to broadcast the new network. I believe in these areas the phone goes into roaming and utilizes Rogers 1g/2g network.
Hope this clears up the issue for you

Wow...thanks for the great info! Weird thing is, the ONLY place i have ever had any problem is at my work (a university in lower mainland). Is there anything I can do? Seems like most calls go straight to voicemail. Thanks for the great info again!
Unfortunately some buildings are just great at blocking signal due to their construction or design, I know a lot of University campus buildings are designed to block cell reception to prevent phones from being used in class. My workplace building is particularly bad at blocking cell reception. On my old bell phone which was on their cmda network I got no reception at my desk. On my galaxy S with their new network I get anywhere from 1-5 bars but never lose service. If you're in a building that does block signal, there's unfortunately not a lot you can do outside of holding the phone in a location where it gets the best signal.
it will automatically switch between G, 2G and 3G
as long as you are close enough to a window

I would of thought it was the building too....but my co-workers get full reception. No static, no dropped calls, crystal clear reception. Could it be a Bell dead spot?

very possible
some areas have towers from Fido/Rogers, other areas have towers from Bell
in areas where you get all 3 towers (signal crash)
and you get sporadically excellent signal to almost no signal for data even if you are standing outside or near a window.
if you drive a bit further away then everything is back to normal

Network dies when I turn off 2g

Anyone have this problem? It happens ever time
Sent from my T-Mobile G2 using XDA App
Hmm.... seems like your phone might be in WCDMA mode only... It should be in WCDMA-Preferred since you plan on using 3G and 2G
Go to your phone dialer and dial *#*#4636#*#*
and Diagnostics Menu should come up..... Go to PHONE INFORMATION.... Scroll down and Set Network Type to: WCDMA Preferred
see if that helps...
Thanks for the reply i am on tmobile and it is defaulted to GSM. Will changing it be any different than GSM?
my phone does that as well right now at home even though i have it on WCDMA preferred, t-mo has been having issues with their 4G towers and their DNS servers lately that has been affecting many people with newer phones/SIM cards and in 4G areas, t-mo has not released an ETA on a fix but i have been dealing with it for a month now at my home and i am about ready to switch carriers

Nope, it'll still be the same. WCDMA-Preferred means that then phone will Prioritize 3G/4G signal over an EDGE signal. So If you are in a decent 4G/3G coverage the phone will set itself into 3G/4G mode... and when you move into an area where you have a weaker 3G/4G signal...t han the phone will be in EDGE mode.
Keep in mind that if you're referring about using WCDMA Preferred in a 3G/4G coverage area - but only 2G works - then you have a network issue. This isn't so much a device issue as it is a MSISDN issue on the network or a potential tower issue.
If you get no signal on 3G/4G and signal is there on 2G - check your coverage first - then if coverage shows you should have 3G/4G, call TMO and let them know, they'll need to do a service request or trouble ticket based on the location and breadth of the issue you're having.

After 2 Weeks, I Am Throwing In The Towel

I received the Samsung Focus 2 weeks ago today. After I post this I will be heading over to Amazon Wireless to make return arrangements.
I come from a Windows Mobile (Tilt 2) and I don't think I am yet ready to transition to this type of phone. I depend too much on Pocket Informant and I couldn't find any app to replace that. Actually this is not really the reason I gave up. This is the reason that kept me on the fence.
At my work I have a very poor 3G signal indoors. The signal fluctuates between 2 bars to no signal indication and sometimes switching to Edge. With the Tilt 2 I turn off 3G and that keeps the phone happy. Several times I found the Focus showing no signal (small crossed out circle at the top left). Even after I went to an area with good 3G signal the Focus did not change from its no signal status. I had to actually turn it off and back on (soft reset, I guess) to get a strong 3G signal.
Searching on Google for means to turn 3G off in the Focus showed that only a few months ago there was such an option Settings | Cellular. Apparently now it is removed.
With 3G trying desperately to hang in there instead of just giving up and letting Edge take over, this phone is useless to me 8 to 12 hours a day. The Tilt 2 had a similar issue before I tweaked it to give me the band switch. However the Tilt 2 did not get stuck in the no signal state. I wish AT&T did not remove this from settings.
So long, Focus.
Um... there's totally still an option called Cellular in Settings. Whatever, though. If you don't enjoy the phone, there's no reason for you to keep it. However, there's equally no reason for you to share this information with us, since a large part of your issue is born of ignorance of the OS (not finding a setting that is clearly there) and your lack of enjoyment of the phone should have no effect on anyone who owns one.

Yes, the Cellular option is still there, in Settings. However, unlike screen shots or pictures I saw during my search (see this sample), I do not have the option to turn off 3G.
If your phone has it, good for you. Mine does not. Hardly a reason to call me ignorant for this though.
That's strange. My Focus appears to have better reception than my Tilt 2.
Actually, the 3G only setting is under the diagnostic menu I believe. The should have a thread in this forum on it.

For me, side by side, the 2 phones had a similar reception. The Tilt 2 got an extra bar or 2 when I forced it to Edge. However, the Tilt 2 did not get stuck with the no signal indication.

Sorry, but I do not remember the exact words. I guess I could try again later tonight after I get home. Thank you.

Yeah, that's what I got. I also got my phone from freaking Amazon.com and didn't work right. Had do alittle talking around but they me exchange it at the Att Wireless Store. Have you actually tried any other Samsung Focus Phones to see if its just the phone itself?
I got mine from att store, I'm using the org diagnostic app version, I get same error message.

I would switch phones then. The phone has to be unlocked to switch bands, even turning off 3G. That's stupid, I know. I have a Dell Venue Pro sitting here that can switch bands but that phone is VERY buggy.

FWIW: 3G = "Data Connection" on the Focus' settings menu. As far as I know, 3G has nothing to do with voice calls. I suspect that the name of that switch was changed with an eye toward future data options on cell phones. I hope that helps. (Even the person who posted that picture notes that they modified the label to be "Cellular Data". You can see that in the comments area of the image/post that you listed. )
GrayWolf is correct
These are GSM phone and voice only works on 2G.. data on 3G and Edge if necessary. that is why you can talk and use the internet at the same time. You turning 3G off does nothing for your call reception what so ever. When you turn off the Celluar data you turn off both 3G and edge. Also I believe the bars are only for the voice service.

This might very well be correct, however on my Tilt 2 I have to turn off 3g in order to get full voice bars back in the location where my room is in my house. It doesn't seem to make any sense; why would the phone's 3g connection interfere w/ the 2g voice? Yet it seems like this is the case.

Sorry. I may have used the wrong terms. After all I admit I am not really familiar with all the terminology. I am more like a user. Anyway, on my Tilt 2 phone I have a switch which turn off 3G. This puts the phone in Edge mode. Gives me a lot better reception in areas where the 3G signal is flaky. True, I cannot talk and do data at the same time. Also true that my data rate is slower. But I can receive and make calls while I am in that area.

Nope. Both voice and data work on 3G if it is available. You can tell this by the fact that once your phone is on 3G, you will not encounter the annoying speaker buzz from GSM phones.
The switch in the settings are for cell data connection. If you turn it off, it turns off the data connection, 2G or 3G. There is no separate setting to turn off 3G data only (a commonly requested feature but non-existent on all AT&T phones). You will always have to access the secret menu to select your band (WCDMA or GSM).
The bars are for signal strength, not just for vocie service.

AT&T sends both voice and data traffic over the 3G connection when in a 3G area.
The GSM radio only comes into play when the data connection falls back to EDGE (i.e., 3G signal is too weak or not present).
This is why your call drops when you switch from a 3G area to a GSM/EDGE area.
It's a hard hand off to the next tower.

Thanks - would you happen to have any links that explains this in any detail?
I looked around after you mentioned it and found that I should have ran a few more keyword searches before posting. So far, the best explanation that I've found seems to be here:
"3G or Non 3G-that is the question"
http://forums.wireless.att.com/t5/G...at-is-the-question/m-p/1544262/highlight/true
The specific/relevant portion that I'm referring to is:
Yea 3G is amazing. It's the replacement for GSM. It's a completely seperate network. When in 3G at present signal in some area's might seem a bit more week than GSM because in some area's it runs on the 1900mhz frequency which has less penetration. But AT&T has plans of phasing out GSM in the future for 3G on the GSM frequency.
But 3G on the W-CDMA side handles call's and data, GSM also does handle voice and data. But the two networks are seperate. For example. If your phone is in 3G then the 3G network is handling the call and not transmitting anything to do with GSM at all. But if you travel to a non 3G area while in the call then your phone will hand off to the GSM network to continue the voice call and the call quality will get that crackly raspy phenomenom. Hope this helps!

Graywolf,
My friend is a tower manager for T-Mobile.
He helped setup the initial GSM/EDGE network for Cingular back when they leased tower time from T-Mobile while they were making the transition from TDMA devices from the old AT&T network.
He explained how the call handlers worked and how the air interface works when handing off from UMTS/HSPA over to the GSM/EDGE network.
All of AT&T's handsets are programmed to use either GSM/EDGE or UMTS/HSPA, not both at the same time.
The point is, a handset can't have a GSM voice call and an HSPA data session occurring at the same time. The radios are not configured to allow it.
Many towers run both GSM/EDGE radios and UMTS/HSPA/HSPA+ radios.
Mainly to support legacy devices.
You will also notice that the old network is still there when you turn of the 3G radio in an iPhone or any other handset that permits it.
Yes, AT&T is working to decommission the older GSM/EDGE towers all together to recover the 850Mhz frequencies for use with HSPA+. This will give them better building penetration in large metropolitan areas.
Right now, AT&T does use the 1900MHz band for HSPA, and as the residence of NY will tell you, it sucks at going through walls.
You will have to do some digging for old AT&T press releases, but the info is out there.
Gotta give credit where it's due. I appreciate the technical detail combined with layman phrasing. I'll do more digging later but you've given me a nice high-level view of things. I did have a suspicion that my understanding was flawed somehow. Thanks for taking the time to share, rjohnstone!
Yep your right I typed it wrong.. voice and data both work on 2G and 3G, but I know I'm in a 3G area only and when I turn data off 3G goes out. Now that doesn't mean I'm only making or recieving calls on the 2G band. It just mean 3G data is off. So if you want to turn off 3G all together, I don't see it on these phones yet. When I turn the celluar data back on, the 3G symbol comes back on, because it would be pretty dumb for the 3G to be controlled by turning data on and off.

Signal problem theory/research

Hello, i live in a relatively small town where my service provider has very poor 4G signal. but pretty good 3G signal. With the Axon 7 i have a lot of signal problems that i didnt have with any of my previous phones, where outdoor signal is pretty bad and indoor signal is almost unusable. It also connects almost exclusively to 4G, and in contrast all of my previous phones connected almost exclusively to 3G. Over the last weekend i traveled to a major city where my service provider has very strong 4G signal, and the signal problem was almost non existant. I even had signal in places where other people with the same service provider did not. So my theory is the following, assuming that the hardware (antenna) used for 4G and 3G is the same, it may not be a hardware problem, but a problem with the software having a hard time knowing which band/signal it should connect to. It seems that in my case it prioritizes 4G signal and the cost of a VERY unstable cellphone service. This is also assosiated with the fact that when it connects to 3G (incredibly rare), the phone goes inmediately from 1/2 bars to 4/5 bars. I also changed the SIM configuration to leave LTE out, but either for a visual bug or a software bug, it keeps connecting only to 4G. So could this be the problem that me and a lot of people in low 4G signal zones are having? Is there anyway i can force the phone to connect exclusivly to the 3G signal to test if that is indeed the problem?
Regards!

Without knowing which model Axon 7 you are using, where you are using it, and who your provider is, there is little anyone can do to help you. All I can say is that it helped me A LOT to go into settings and turn off
VoLTE.

U model last update, using it from Argentina, and the provider is Claro. I have LTE disabled in SIM confg as i already said and VoLTE turn of as well but the phone keeps connecting to 4G no matter what i do, even if i configure it to only GSM
I don't think its a matter of position or provider (version could be if different software is provided), but a general issue with the phone and band/signal interpretation coupled with the apparent innability to go off 4G
Refards!

ok when it connects to LTE it says "4G LTE". The 4G that you are getting is probably HSPA or something. And we had someone on here a few months back using Claro in Argentina and they had to seek answers from their Claro

If "4G LTE" is 4G and "4G" is HSPA, when only a "G" appears, what band am i connecting too? Its still pretty weird that im having major signal issues in my town, but when i go to a big city my signal is even better than other phones, it seems inconsistent with the whole "bad hardware" theory. I talked to Claro and it seemed like from their end it was a non issue, can you point me to the thread to see if he got it fixed somehow?
Regards!

/Trolling a bit/
I'm always LMAO when I hear US people talking about that 4G scam (which is H+ for real btw)
G is for 2G
E is for 2G+
3G is 3G
H is 3G+
H+ is 3G++ (an intermediary protocol up to 42MBps)
4G is LTE (up to 150Mbps in the EU most of the time)
4G+ is LTE-A (which is available in most of the EU, SK & JP) - up to 600Mbps, 200MBps in most tests
I've not heard of an app that could modify the way the phone "clings" to 4G LTE, since that might likely be the modem firmware doing it on its own.

Then this is even weirder, because is G is not 3G, but 2G it means that the phone NEVER connects to the major band that all of my previous phones and Claro users connect to. Is there anyway to force to only connect to 3G?
Regards!
i have the G european model, in my town i have bad lte signal 1/2bar, when with my previously xiaomi mi4c was got 4/5 bars (maximum). In the big town i have got in the most of cases 4/5 bars. I think the "signal problems" are relatives of a lack of somehow software. i told this because i've read with the china model with the last updates an improvement of the signal reception of the phone.

You can however force a specific protocol indeed, but you will lack the ability to autoswitch networks. Just download 4G LTE Switch (here) which is a glorified secret code dialer. Just click on prefered network and change at your convenience (4G LTE only, WCDMA only - H+ - and so on). Remember that if you force 4G LTE in an area in which you have no coverage, you won't have internet, and no 2G/3G fallback (so no texts, no calls)
I don't know if this is the same problem, but my wife has an iPhone 6+ and I have an A2017U on B29 stock root. We both use the same network (Movistar Mexico) and while her iPhone often registers LTE, my A7 often registers 4G or even E in the same place. The A7 is receiving the same bands but appears to be "choosing" or locking into the slower protocols more often.
EDIT: NEVER MIND… an xposed module was messing with my network settings. Fixed it. Now I get LTE right away.

Which module?
What if flash any Custom OS?Would it give better signal ?
