[Q] NxS jumping between 2G/3g?

Anyone else having a problem with the NxS jumping between 2G/3G network all the time?
I tried 2G-only and it seems the it does interrupt connection less often, but it still does. I'll exchange the sim card tomorrow to rule out the last option (I can think of) I got before returning the NxS and asking for a replacement.
(i9023, stock rom/kernel/radio, tried 3 stock roms with diff radios (KA3, KB3, KD1))
Maybe anyone got an idea or a hint.

Sounds like ur in a weak 3g area so it keeps goin back to 2g

Granted I'm not in the best 3G area, but I usually get 3 (of 5) bars in 3G and then it just pops back to 2G.
Might be network pumping (or w/e it's exactly called), gonna exchange the sim anyway to track down the problem further.

Are u on orange in the uk

I have this problem aswell. Thing is 2 3g bars are way faster than 4 g bars. I cant change it to use only cdma in the service menu. Anyone know why.

So does change of simcard help?

I got it fixed for me. I tried n3 and n5 sim cards, no changes. Problems were caused by faulty antennas, after being fixed by the carrier problem was reduced to a minimum. Now to get rid of the so called network breathing, which is a problem of the used communication method itself aka can't be fixed. University ftl!! Simply too many smartphones

Poor reception on S3 somewhat fixed

So let me start off by saying I have pretty bad reception at home with 4g.
I had an iphone 4 with a 3g range extender before I got the S3 and it worked great.
Found a free app called phone info
Went in under device information, selected cdma auto (PRL). I restarted my phone.
I now have 5 bars and perfect clarity.

You get 4g in CDMA auto (PRL) mode?

I am usually about 2 bars where I am. Making this switch didn't change my number of bars or dbm. I'm glad it worked for you however.
I expect by making this change, you are basically downgrading to 3G until you set it back.

If you have a network extender for 3G then that's the fix. Not turning on thst option.

I am downgrading to 3G and my range extender only works for 3G not 4g. Verizon claims to not have a 4g extender yet.

Not exactly. The phone will stay in 4g with one bar even if 5 bars of 3G is available. So forcing the phone to switch to 3G is the only way I got the call quality I needed to make calls in my house

What's the make and model of this range extender?

Unstable 3G performance
So I've had my S3 for a little over a month and have noticed the poor call reception that people have mentioned,especially in my office building. My old droid 2 global never had a problem, but when I receive calls on the S3 i have to walk to A window down the hall to keep the call from dropping. In an attempt to stay on the more stable 3G coverage in the area I installed phone tools and forced 3G. The problem I have now is that when I'm out of the office or house and not on wifi, I pull the phone put of my pocket to check something and there is no data connection at all now. Even if I open my browser and try to force a connection I get nothing. If I set the radio back to include LTE I have a reliable data connection everywhere but my calls are still poor.
Am i missing something when setting the phone to be 3G only? Thanks.

Ok i tried that phone info program and set it tup cdma auto or whatever, and no improvement. How do i get back to stock? I tried setting to lte/cdma/evdo but it does not stick. I tried uninstalling the program and the phone would stick to 3g. Help!

Just download the phone info app and switch it back to lte/CDMA/evdo when you switch it turn off the radio at the bottom and wait for a couple secs then turn it back on

I wish Verizon and Samsung would just get together and try and resolve why their phones don't work well on Verizon's network. I figured they'd learn what they did wrong with the Nexus - pretty upset they never resolved it with the S3. I'm hoping the DNA/DLX from HTC doesn't have this issue. I liked the Samsung S3 in just about every way but the reception is wretched compared to Motorola phones.

yea I agree...the reception is awful. Literally can't use the phone for business. Everything else about it is awesome though

I'm missing something. How does 3g/4g have anything to do with your calls? The phone works with data turned off. Are you using Skype?

It has to do more with your location I think..I work in the tri-county are of Detroit and my reception is excellent. Had a Cappy on ATT before my GS3 on Verizon and could not even get a signal in our office building..now on Verizon I'm at least 4 bars and full strength pretty much everywhere else..

It seems to have to do with the technology of the Verizon towers in your area. In LA with a motorola phone I lock on no problem and get great reception. With the S3 you'll switch from 4 bars - drop the call and switch back to 4 bars even when stationary. Motorolas don't have that issue with Verizon's network. I know several people with the S3 including people in CT and TX - all having the same issue on Verizon's network.

Nexus 5 dropping me off Network ??

So I got my nexus 5 on Friday and its perfect none of the mentioned defects was having some small issues with the notification light but that's all. However I noticed once a day since getting it I go to use my phone and it says emergency only / Rogers and I won't be able to make calls or receive calls. Anyone else experiencing this problem ?

I'm on Bell and for some reason sometimes I'd have no signal out of no where then it'll jump back to full bars the next second... Really annoying unless this is a normal thing for the Nexus 5

I'm on Rogers and I get this too. I usually fix it by going into network mode and change it to 3G and back to LTE immediately.
I still get incoming calls even though I can't dial out until I do the above change.

Its network problem not the nexus 5

I have the similar problem i'm on rogers and if the signal gets weak it will show signal strength in the home screen, i can surf the internet(data), but will not send text messages or make calls, if I try to make a call it say "cellular network not available", if i turn air plane mode on then off it reconnects right away. this has never happened with my GE Galaxy S4

I have the exact same issue guys, I hope that it has nothing to do with our nexus 5's.

im getting this error too. darn! its not normal for a phone to be like that. never happened to my previous one.
there must be something wrong with the phone.
im on Fido.
but its only happening to canadian network? weird.
maybe they're torturing people who didnt buy from them? lol

It looks like I have a similar issue.
My connection sometimes gets lost. Some sort of hiccup when connected to mobile network.
No issues found on WIFI

I'm on a hspa network in Canada and wanted to report that I get worse reception with the N5 than I did with my Galaxy S2. I hope it is easy fixable with a new modem flash or other update.
Just wanted to contribute in case there is anyone working on this and wanted some more info.

I had to change my data plan because, according to T-Mobile (US) it was not compatible with the phone. I could get emails and SMS text messages but could not get Internet data services (kept being prompted to log onto the network and presented with the T-Mobile logon screen). Lost my unlimited data, which I was grandfathered into (but found out that they were throttling me at 5 GB which I don't usually hit). I knew they would eventually make me change my plan anyway and was able to get a new 4.5 GB plan at the same price. Since T-Mobile will be offering this phone very soon (tomorrow? they're taking pre-orders now), I guess a lot of long-time customers will be pushed off their unlimited data plan.

I have the same problem!! It's really annoying - mine gets dropped every 2-5 mins! Is there a way to fix it? Is it the N5 or Rogers network?

I have the same problem in Belgium:

If you are constantly getting poor signal it might be the handset. If you have good signal, and can use data, but have "Emergency calls only" instead of a carrier name, it's probably a carrier issue.
I am on Fido and have randomly had the same problem. There's another thread somewhere, and most if not all people reporting the problem are Rogers/Fido customers.

good point though... i don't see anyone from other canadian carriers complaining.

I also have this problem. I am on Fido in BC. Sometimes it will completely cut off the network signal from full bars to no service, similar to no sim card installed. It goes back to normal in about 5-6 seconds by itself but its definitely annoying.

It is a software issue. I switched to a different ROM and kernel.
Cataclysm ROM and bricked Kernel.
So far, the connection is solid with this combo.

LTE and phone calls

I am in an area where there is the eCFSB gap problem. For those not aware this is basically where my area has lte but triband devices can't get it. So yesterday I was surprised that I was finally connected to lte. I thought it was finally fixed. Now my problem is I can connect to lte but I can't make phone calls. What happens is I'll try and make a call the lte will disappear like it's supposed to and it will say call sent. Then it will immediately say call failed and lte will reappear. If I turn lte off and back to 3g then phone calls work. I can receive calls just fine on lte I just can't make them. Anyone else with this problem? Thanks.

Could you provide more detail? Service provider, kernel, Rom, if your SIM card is an LTE one or from an older phone that didn't support lte.

I have the same issue, but only in some areas. I do not get any incoming calls when I am in LTE area, if I change it 3G i get the calls.

You are not alone. I'm on MetroPCS gsm which is basicly T-Mobile. Anyways, I forced my phone to stay on LTE only and I was not able to make or receive any calls whatsoever. Make sure your phone is on automatic mode and not force LTE on becuase that was the only way i was able to get the issue to occur was through force lte on. There's a few threads regarding this issue that might be a good read especially for sprint.

Phone doesn't reconnect to LTE after dropping to 3G?

Anybody else having this issue? LTE works fine until..it doesn't, and then even if I was getting LTE in the exact same spot, it never jumps back on it. Once it's in 3G, it stays 3G until I restart. Any way to fix this?

You are in a area where they have not fixed circuit fallback. ... they made the phone do this so you would get calls and text ... triband phones use cfbs to push through calls so if your connected to lte you will not get calls and text.

I get what you're saying, but I don't believe that's it-- I stay on 4G most of the time, but once I get a call and it shifts me back to 3G, it never moves me back to 4G after the call. It just sits on 3G until I cycle airplane mode or restart the phone.

Actually, if you read, it's not. If I wasn't in a CSFB market, then I wouldn't connect to LTE at all except for a moment, and then drop off. I do connect to LTE, and receive calls without a problem. But let's say I pick up my phone and walk into another room where the LTE signal isn't as good, and my phone drops to 3G-- when I come back to the good LTE reception room, it should reconnect, like my previous phone would. Instead, it doesn't. It has nothing to do with CSFB.

Ok well good luck getting help fixing this problem with an atittude like that. Since I've had this phone, I mostly see 3G but with my S4, I never saw 3G. I can get it to be on LTE all day long when det to LTE only. Its something to do with 3G/LTE hand off and the single band data/voice radio.

My "attitude" was simply to correct you, since you either didn't read the article or didn't understand what I'm talking about.
I can agree it's probably something to do with the hand-off and/or the radio/how aggressively it decides to change connections, but that's not CSFB.
