Signal problem theory/research - ZTE Axon 7 Questions & Answers

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 ?

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.

quantum reception??

hello everybody...just received my quantum 2 days ago (i live in italy)...it was locked to at&t so i unlocked it with a code...but the reception is very bad, so i wonder...if i debrand the phone from at&t perhaps it will get better reception...what u think? because the signal only shows g/3g and no 3g+ or H....i'm a bit worried about that...help please! =)

If the phone is showing 3G at any time, then you are set up for the appropriate bands to get high(er) speed data transfer and 3G voice. If you only see E, then your carrier is using the other bands and unfortunately, there is no way to reconfigure the phone via firmware.
As far as general reception capabilities of the Quantum, I find it to be superior to the S-E X10 I used to use (I still have it), so I don't think there is anything wrong with the design. What phone were you using before?

i had an omnia 7...but it's the first time i use a phone that comes from the US...dunno, it's weird, because when the omnia was under hspa, tha phone showed me always 3g+...and with tha quantum it shows me always 3g, and very poor reception (only 1 bar)....but the most of time the signal is under gprs only....it's pissing me off =(
You are correct. This phone has really bad wifi and wireless reception. I had flip phone before this and in places where I had 1 or 2 bars before with LG I have nothing, no signal. Yesterday I had to leave Ikea building and turn phone off/on just to get reception because if after spending 2 minutes outside he couldn't lock the signal.
Regarding wifi, at home I have hi-gain antenna on my router. I can take my laptop outside on the parking lot, sit in my car and still browser on the internet. This is around 30m distance through 1 thick concrete wall. This phone is struggling to get signal on the opposite side of the home, behind 2-3 drywall walls.
I constantly have signal changing between 3G and H. Were unhappy with reception.
AT&T phones don't show H+ (3G+), it just reports it as 3G. Signal wise I live out in the middle of nowhere and I got pretty decent signal with it. You can change your primary band settings under the MFG app though (because its AT&T if 2100 is available it automatically swaps to it, although where youre at 2100 may not be a primary band).

Low signal - not the phone

So I've been using this Omnia 7 for a while now. Fantastic phone. I bought it from a dealer in the UK and have been using it in Canada.
The phone works great with my carrier, but it drops signal every few minutes and refuses to get it back for a while. It's on the latest version of Mango Zune finds. If I leave it sitting in a spot, it gets full 3G+, is blazing fast, sends and receives texts instantly. But if I'm on the move, it's constantly dropping signal.
Anyone have any idea how I could fix this? It's becoming really annoying.
I know it's not the phone's hardware - I sent in the previous one because I thought it might be, and I had the exact same issue.
don't know what frequency your carrier uses but on att in US it doesn't support all the bands.. it's usually good for me though but some areas I have to disable 3g and I get better and consistent signal on edge. needs to be unlocked use samsung tools to enable 3g toggle
My carrier supports tri-band HSPA (900/1900/2100) and GSM. I regularly get 3G+ or full-strength 3G around the city - however, it seems that if I move around it drops signal right away.
For the 3G toggle, do I have to do a Chevron unlock? Or is there a simpler way?
I've had this problem for a long time and there simply doesn't appear to be a fix.
Oh, man. That really saddens me. I love this phone, and it's perfect when it works!

yes you need chevron unlock to install the xap, it will add the toggle to your "cellular" settings menu

It's bizarre, truly. My city isn't that big, and my provider has a pretty good network. There are moments where I'm on the road and I have blazing-fast 3G+, then the next second no signal at all, repeat. I know it's not the carrier, because my old phone (using the same SIM) had no such issues, and I know it's not the hardware, because this is the second Omnia to do this. Gah!
I'm wary of Chevron unlock because everything already sort-of works, and I already have a Data toggle... I don't want to make it work less, especially because I have no idea what firmware I would restore to if I mess up.

Manitoba Telecom Services in Canada. I checked, and they have the exact same network type as T-Mobile Germany, which is where this phone originally came from. It should work fine but it doesn't!
strange issues, sorry but i believed you were from Europe, anyway the phone should automatically switch to E (dge) when it's not covered by 3G+, at least this is what happens to me, but i'm on different carrier

I think it's just low signal strength - it's typically out of reception in buildings, tunnels or basements, even though my old phone had reception there.
I live in London, I am on T-Mobile, with a T-Mobile branded handset which i chevronned to Mango.
I have lots of signal problems, which I posted about previouslty.
Would love some help - generally my signal either gets stuck on GPRS, or zero. I rarely see 3G in places I used to get full 3G+

Network mode problem

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.
