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.
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.
Hello,
I am casting a broad net on the internet here to get a consensus with what is going on with the LTE problem many are having with their S5''s
Does anyone NOT have an issue with their phone going from 3G to LTE then back again. A lot of people (including myself) have to toggle airplane mode on/off just to pick up LTE. It does not automatically connect for some reason.
For added information, I am in a non LTE launched city but have been testing by a known LTE tower. when I drive up to it the S5 will not switch over to LTE. When I toggle airplane mode it works.
I guess long story short. Is there anyone out there that does not have this issue?
Thanks a ton for any information!
I don't have that problem I always have LTE unless I travel far out of the city which is normal with all the LTE phones I have had.

Think it's an issue with your provider, I've tried LTE/3G with four different providers here in Denmark without any problems.
Could be an issue with the SIM.
Also, which version of the S5 do you have? EU, US, Asia, etc? BRanded? Unbranded?

I do not believe it is actively searching for a LTE signal all the time. It takes a min or two for my phone to pick up a LTE signal once I'm in a known coverage area. I've done the airplane mode toggle before as well..... It forces the signal search right away.
I'm sorry I should have mentioned that I am on sprint. I will be going into a launched LTE city here today and will do more testing.

Yeah I'm a Sprint user too. All of my Sprint LTE devices have behaved similarly. It takes a few minutes of being in a known LTE coverage area before my phones (both IOS and Android) would connect. Its because the radio isn't actively searching all the time.... I'm not sure what the actual search interval is, but it's not constant. And again my Iphones behaved just the same as my current S5.
My Evo 4G was constantly searching for a wimax signal when I wasnt in a coverage area.... it really sapped the battery because that radio was always on the hunt for that wimax signal.
Got no issues of this kind
im on tmobile im having the same issue ,never had this problem with my s3lte
I don't have this issue, however on one occasion at work I lost 4g signal which is usually at 2 bars, and it sat there and didnt connect to 4g again until I did airplane mode, then it came back fine. But this is the one and only time I have had the issue.
this is a sprint issue
you need to wait until they finialy decide to update their towers to handle the new triband phones, they claim they will be done with all the updates by the middle of the summer, i got sick out their sub-par coverage and took all my lines over to verizon... no regrets
details about their issues are here, it is a long read but good:

S5 LTE Hand-off Loss of Signal
I'm a Sprint customer on Long Island, New York and I've been having the issues as well. I had to deactivate the S5 because it would lose data and even phone service sporadically without any warning. Sprint's solution is to go into Airplane mode for 5 minutes then back, but that's 5 minutes without service after noticing that the service is gone (and losing how many calls/messages). My girlfriend has one too and probably misses about half her calls (and texts come in late constantly) What happens in an emergency? I recently blogged about this. Isn't Sprint opening themselves up to liability by selling the phones while these issues are known internally?
Im in Denmark too, and i have the problem with Telenor, but did not have the problem with Telia, unfortunately i have to stay with telenor, work phone

You didn't do a forum search or you would already know that it doesn't affect everyone. There are myriad threads about this and the concensus is that it is carrier dependent.
Open a support ticket with your carrier. Also, the 4.4.3 update is said to address this bug, so that is something that you might want to look into.
.
Just a little update, put on download booster, and after that no problems whit disconnect from network, will see later when i leave home to see what happens then.
Hello.
I have a note 3 n9005 and when the network mode is WCDMA/GSM or LTE/WCDMA/GSM, my phone stays on GSM often. 3G signal is good in the area, and when I check my friends' phones, I find out their phones are on 3G network but mine is on 2G.
When I choose WCDMA Only, phone registers on 3G network and works without any problem. But switching back to auto connect, cause the phone to register on 2G again after some time.
So is there any configuration that tells the phone to stay on 2G if 3G signal is weak?
Please help if you can.
Thanks in advance.

The cell tower does this by signal quality, and most of the time distance dictates quality. I myself have asked around for AUTO 3G/4G only, but it seems like a subject where nobody has done any research.
Does your 3G signal differ from WCDMA only compared to Auto mode? If so, try updating to a newer firmware, could be a modem/baseband issue that may has been fixed in the mean time.
Technically it should grab the highest network of the three. So LTE has priority over WCDMA, which has priority over GSM. So even if WCDMA has one bar, and GSM 4, it should grab WCDMA until it completely loses that signal.
Have you tested another SIMcard in your phone? It may very well be a SIM problem.

You say it is fault of the cell tower?
So why phones of my friends are ok about this issue and register on WCDMA?
I flashed 3 different lollipop ROMs but nothing changed. ?

Yes. That's exactly what I expect my phone to act about switching between network types.
I never tested another SIM in my phone. So I will check that as soon as possible. I will post the result. Thank you.

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.
