Hi Guys,
I recently switched from the Nexus S forums to the Nexus 4 forums
I'm loving my N4 so far
Perhaps too much, because I've been ignoring a problem that I've been facing. My phone drops the mobile network for a few seconds, once in a while.
I was able to find a way to replicate it. I think this happens when the N4 tries to switch on data on 3g or H.
To replicate this,
1) I installed the Network Signal Info app(can't post link here )
2) Next I tried to switch off wifi. As soon as the wifi is disconnected, the phone tries to connect to mobile data network and my phone disconnects completely for a few seconds. See attached screenshot for logs.
Anyone else facing the same issue?
Thanks,
Spaccount
Note that I can't replicate the issue every time. However it does occur very frequently if you first keep it on Wi-Fi for at least 10 minutes.
Thanks.

Note that you need to be on wifi for alteast 10-15 mins before this works..
I tried loading the browser to show the problem(no network).. but I also get an error if I try calling or texting..
Can someone please try to replicate?
I'd like to know if this is an isolated hardware issue. I just finished 2 weeks on my phone.. Hopefully I can get it replaced
How long is mobile data disconnected? You do know that if you are on wifi mobile data is disconnected on all phones, it reconnects when you either turn off wifi or go out of range of the wifi network. It will take a few moments for it to reconnect to mobile data and vice versa, its not an instantaneous reconnect, it can take 10 seconds or a minute or two.

you are correct!
However, during this time period(as in the video), I'm completely cut off. I cannot even send a txt or make a call.
I didn't demo this because I wanted to keep my call list out of the video.

Okay I see what your talking about now, I had removed Network Signal Info off my phone and just reinstalled it. And no my phone doesn't totally drop signal, it drops but not by much when it switches from wifi to mobile data. Are you on stock or custom ROM or Kernel. Its like your radio is turning completely off during the switch to and from wifi, If your on a custom kernel I would suspect it to be the problem. If not then it might be a hardware issue.

Happens on my iphone 5 on t-mobile when is goes from edge to 3g or 3g to edge, I think it's cause of the phone switching the bands

Interesting! I'm on t-mobile as well.
I just did a factory reset(the google lady told me to) and I still have the problem.
Is there anyway that you can get hold of a Nexus 4?
Also where are you based out of? I'm in Ohio. Not sure if that matters?

So maybe its a carrier issue, I'm on ST AT&T. You on T-Mobile by chance? I had signal issues when I had them and dropped them in 2 weeks. Could only get a weak signal in my living room and then would get no network detected in my bathroom 10 feet away.
Okay not sure what caused this but I had my phone off for about 20 minutes and when I turned it back on to retest it I got no signal, then turned off wifi and signal came back, then turned off wifi and signal remained the same. Not sure if this effects my ability to send/receive voice or text. Its probably just the phone saving battery by turning off the cell radio.

I am on t-mobile.
However the network is OK around here. It would be great if someone on t-mobile and N4 can try to replicate this.
I had this issue with my previous defective device. If gps was on the mobile connection would crash. My new device does not have this problem.

I had this exact same issue when I first received my Nexus 4. I thought it may had been a faulty sim card, so I replaced that, twice, same result. I went ahead and formated the phone back to stock, same result. Checked and made sure APN settings were correct, same result. Contacted T-Mobile, they reset my phones service and the data in my area, same result. After both I and T-Mobile ran out of ideas I decided to contact Google for a replacement. Turns out it was a faulty antenna and my new device has been working fine since.

Thanks for sharing this!
I just called google and requested a replacement.
The lady said I should get an email in 2 days. I'm on day 13, so I'm cutting it close
Also wanted to add that I ran the same test(as in the video) while on a phone call. It dropped the call and locked me out of the network for 10 seconds just like in the video.
I logged to XDA to report this issue it so annoying and the biggest proplem that my N4 seems to stuck on 3G and won't open internet untill it connects to H
it also happens when connected to E as I dont have 3G coverage over there and it also drop many times
mine seems to cut the radio off for seconds

Based on the following link, this might be a software issue. I know the issue described in the link is not exactly what I experienced, but is similar in some ways:
http://code.google.com/p/android/issues/detail?id=40514
It's supposedly fixed in 4.2.2
Will let you know if I get the update before I RMA(don't want to force the update).

Hi All,
I wanted to share an update. I got my replacement device yesterday. It works just fine.
So this is a hardware issue.
Thanks for all your help with my questions!
Similar problem on Galaxy Nexus
Hi all,
first of all, I know that there's a different forum for the Galaxy Nexus, but since I have a similar problem as discussed here I thought maybe someone can help...
I also have random disconnects from my mobile network, but since I almost never use WLAN it might not be the exact same problem as discussed here, right?
I'm running cm-10.1-20130416-EXPERIMENTAL-maguro-gerrit-35930.zip, and - as I said - my phone randomly disconnects (shows the "no signal" sign in the status bar) and relatively quickly connects back to the mobile network and everything works like normal. The whole reconnection process takes about 5s or so, I don't have to re-enter the PIN or something...
Any ideas how I could figure out what the reason might be?

Has anyone been having issues with the G2 Data? This morning and another morning this week my data failed, I tried going into airplane mode then restarting the phone completely still no signal and no cell signal either. My friend has a hacked and unlocked iPhone and his is working fine so I know its not a network issue with the towers... As well another co-worker has a myTouch 3g with no reported issues. Thankfully I have a wifi signal here at work.

That unlocked iPhone your buddy is using is EDGE only, obviously. That's going to give a better connection inside. Try running 2G only mode next time you get that issue.
I bet it was just a brief network outage in your area. It happens sometimes.
Not brief if it's a network outage... my connection is still gone... both my friends have theirs and one is on a myTouch 3g...

Sounds like you have a problem then. I haven't experienced that on my G2 yet. My N1 forever had data connectivity issues.
Are you using the new simcard that possibly came with your G2? I have no idea if that makes a difference, but just asking...
Call T-Mobile and see what's up. Maybe they can refresh you on the network.

Good luck.

Tmo has been having issues, there are several reports of this and all my demo phones are unable to get online(though regular signal is fine) I would call care to let them know you are having issues too, ask them to make a ticket and/or send an engineer

I had to exchange a couple until I got one with a solid 3G connection. Previous G2's had no connection or were in Edge 90% of the time.
Nothing wild here.
It seems to work as its supposed to.
Would love to see mine switch to 3G. Been on Edge 100% since I got it Tuesday. Advertised in a soled 3G area, but no luck. T-Mo CS politely told me I will love Edge. Will be switching to Sprint Epic if nothing changes in next few days.
Mine does that too. I have to restart it.
Wonder if the supposed OTA-vapor new radio will fix that.
I've been having data issues too, seems like it has to do with how my phone is held (HTC antennagate?) I hope the mythical OTA comes with a radio fix (if that is the cause) and/or a vorpal blade....

I have a ticket open with tmobile about my data issues.
I'll have my phone on the desk and it'll have 1 or 2 bars of H and then I'll pick it up and its goes to G then to E then to nothing. Its worse when I open the keyboard.
I love this phone so much I hope its just a software fix. Is the OTA going to have radio fixes?

Exact same problem here. It's so frustrating. I've already exchanged it once and spent an hour on the phone with tech support. If it keeps up, I don't know what I'm going to do.
I am not liking the data issues.... I love the phone besides.
Fixed with a soft reset but that has to change...
There are a bunch of us with signal issues. I live in Vegas where we have great HSPA+ coverage and Im still getting a lot of issues even with 3G, that I didnt have with my Nexus One.
Check out the thread on the T-Mobile Forums. (I cant post the link since Im new here )
My issues are simply the phone works one min then the next there is ZERO signal, if I dont move but restart the phone I have full signal again. Some times the signal comes back on its own then other times it doesnt and I have missed calls after the restart.
I bought my dad a G2 as well (upgraded him from his G1) for his birthday, and he is having similar issues. I went into my local t-mobile store and they replaced the sim card 2x now and that didnt help. What I did find that helps is that if you set it 2G mode the phones seems to work fine. This is a temp fix but its retarded that T-Mobile's fastest phone is being forced to run in 2G mode.
I hope someone on here can figure out the issue or t-mobile comes out with a OTA fix asap.
Wow, the rep just tried to tell me I live in an area that is only covered by edge. I asked why I've had 3g hooked on my phones for the past 2 years and why my girlfriends phone says 3g. She then said I was wrong and she didn't know why the last rep told me I was suppose to have 3g. She then directed me to the coverage map where I pointed out to her how wrong she was.
....and she's a PDA specialist.
What upset me was how she was trying to convince me I lived in an area where 3G was not available. Despite having had 3G at this location for years. I told her I'd just call back tomorrow.
Edit: She must be on drugs, I see that I'm back on 3G.
The rep on the T-Mobile forums is asking you to PM them your info:
Hi everybody!
If you are experiencing this, we would like to hear from you. Please send me a PM with a few details. The location information requested is particularly important.
(Do not post your private information here in public.)
1. Describe your signal indicators when things are working well. For example, "Full signal with an H."
2. Describe your signal indicators when you are experiencing the issues in question (No signal, one bar, E, G, etc).
3. Provide a location where you are experiencing issues (city, state, zip code)
•Are you aware of other T-Mobile phones experiencing or not experiencing these issues at the same location?
•Are you indoors or outdoors when you are experiencing the issues in question?
4. Provide a location where things are working well, if available. (city, state, zip code)
5. The T-Mobile phone number in question.
Thank you!

I've had prevalent connection issues as well. For me, turning off Bluetooth and WiFi fixed the issues and I was able to get data via mobile network again. Bluetooth seems to be the main offender.
This exact thing used to happen with my N1, and this was fixed with rooted builds (Cyanogen/Enomther) from what I saw...... *grumble*
Sorry to resurrect such an old thread here, but I'm having data issues today in the Chicagoland area. Anyone else having problems?
I first thought it was an issue with the latest CM7 nightly I flashed last night, so this morning I reverted back to CM6.1.1 and still having problems with data. It shows I have 3G/H and strong voice signal, but no data is coming/going. When I reverted back to CM6.1.1 I did a complete wipe and then nandroid restore.
Thoughts?
I've had my Atrix for a couple of days now, and twice internet connection with AT&T just stops working.
Going into airplane mode and then back to normal still does not fix the issue. Wifi works, however this should not be the solution.
Besides AT&T Gimping our HSUPA speeds and not providing an app for the FM Radio, the loss of internet connectivity is pretty annoying.
So far the only way for me to resolve the issue is to shut down or restart the phone.
Has anyone else experienced this? I have not rooted my phone yet because I want to see how things work stock.
Any information would be appreciated.
Thanks!
I had this happen to me 3 times already..among all the issues i am seeing with this device.
You are correct, nothing helps but a reboot.

Gimping the HSUPA is...but how are not providing an FM radio app and the connectivity problem you're having AT&T's fault? Nobody else seems to be having a problem losing connection (meaning it's either you or your device that's gone bad) and the FM Radio not having an associated app is Motorola's fault.
Assign blame where it's due, plz.

Because AT&T is the APN providing internet access to our phones. Motorola has the FM hardware built in, AT&T is not making use of the FM Radio hardware which is already provided by Motorola.
If I was the only one with this problem, then others would not have stated they have the same issue.
So I blame AT&T when there is no connectivity on my phone because I'm paying them to be my service provider. AT&T also has restricted many features on phones which have applicable hardware.
Besides, you are not the authority as to who I wish to blame. If you don't have anything useful to post, then I suggest you just stay quiet since your reply is just wasting our time.

Mine has done it several times. It seems to happen after the connection drops for a weak signal. Then for some reason never comes back on. It is not just my internet connection, it is my entire signal that never comes back. I can't make calls either.
Same here, several times... id expect a patch coming shortly to remedy some of this BS.
i think all of these network issues all arond may be due to a deadline att has not met and is severely late on its 4g. Its prob updating its system. Just speculation.

I had the same problem today. I turned my wifi on because I was home and then I wanted to test my 3G speed at home. Turned wifi off and then I lost the data connection. It showed the H+ symbol and full bars but not the arrows below the H. I had to reboot the phone to fix the problem. Airplane mode didn't help.

Hi All,
Long time follower, first time poster..
I have a very annoying issue with my Nexus 4(4.2.1 and rooted on Tmob).
I use wi-fi connection at home and work and in-between I switch to HSPA or should I say, I was able to..
Lately I have been seeing that If I leave the Wi-Fi area, the phone doesn't switch to cellular data and the connection gets lost.
Switching to airplane mode and back brings it back most of the time but it's really annoying having to do so..
I did find an issue #40514 on the google android code page( code.google.com/p/android/issues/detail?id=40514)
Tried the suggested work arounds like "Auto Network" setting and it didn't seem to help..also have tmob in the APN settings. Still the only thing that works for me is toggling the airplane mode.
This happened to me once on my previous Gnex but with N4, it started to happen all the time.
Does anyone have a better solution to this issue?
Thanks
Oz
even I face the same issue with this new Paranoid 4.1.2 ROM for Atrix 2. I've noticed only one ROM gave me consistent data 24/7, it was from same dev altered his NUMA B2.
But other than that, this has been a repeating problem in all ROMS. Data stays on for hours without issue but suddenly drops and never comes up, other than air plane toggle. Somebody mentioned it is with the network and trust me it is not..
but I'm also eagerly waiting for a solution

Just throwing in my two cents; I starred the threads that I *think* are related on the google tracker. My experience is like this:
I start up Sirius on my phone before leaving home (On wifi)
Driving to the end of my development and then lose WIFI which in turn turns my 3g/4g gray for about a half mile
Picks 3g/4g back up eventually
As I'm driving to work if I end up picking up any open WIFI spots that have a login, once that happens I lose 3g/4g again then have to either wait till that access point is out of range or just turn off my WIFI before data will pick up again
It's pretty annoying; probably going to have to create a tasker profile to turn off wifi when leaving the house and back on when I get home.
Same problem on an LG F6 Optimus
I just got a brand new LG Optimus F6 and I'm noticing this same issue. The phone is stock and runs 4.1.2
Anyone found a solution?
the issue continue in n4 with 4.4?
My note4 almost always has a white 3g above the service bars. However, even though I still have 3G and there is no change in service bars, periodically my text messages will not send and internet will not work. Keep in mind that my phone constantly says it is connected to 3G. It also happens that the signal bars disappear. After reboot both are OK. *
I do not have any malicious*apps*and my phone is not rooted. Have messed with network settings and have seen no change.
And YES my mobile data is turned on.
Any help is appreciated!

I would hazard a guess that it is sim card related.

If have exactly the same issue !!!!
Start with full signal strength and going down to the lowest strength and minutes later no signal !!!
Reboot or Airplane mode can undo this, but the cycle starts allover: Full strength, less strength and no signal.
Tried with 3 different carriers !!
And 2 Note 4's !!
I have the Snapdragon version SM-N910F
What is going on ??
Have this issue with my exynos variant in australia its imported and full 3g signal and slow or no data throughout and sometimes h+ even g or nothing
Next week samsung will come to me and bring my phone to their service and will check whats going on. Anyway I think it's more like hardware issue than software.
I have the same issue with exynos variant I bought the fone from the official dealer in my country,
My data service was not working at all.
I got it working by going to mobile network and choosing WCDMA/GSM option instead of LTE/WCDMA/GSM. although now i cannot get 4g but at least the data is working on H or H+
I think its software as a few people have had this issue both variants also
Same problem here, Exynos factory unlocked SM-N910H. All of a sudden I look at my phone and I discover it's showing "Emergency calls only", sometimes H or H+ but no internet. A reboot OR Airplane mode OFF and then ON will solve both problems. That's ridiculous... I've literally tried everything, factory reset, changed sim, messed with the APN settings. I've had this problem since day 1, even before I rooted it. Darn this, I never had any problems with my HTC One X, and I am using it ATM until Samsung come up wit a fix with an update or something. I hope it's not hardware related as my Knox warranty is void 0x1. :crying:
The same issue happened to me. I have 910c variant from Lithuania. A week ago phone started to lose 4G and after few minutes "no signal". Few reboots and it is working again, but after some minutes there is no signal. What I did notice is that there was no signal problem in my city centre where 4G signal is very strong, but when I did some speed test there, it was only ~2-3mbit (before this problem it was ~50-60)... Unfortunately I did not test this issue by turning off 4G. I did deliver my phone to warranty service 5 days ago and they send phone to Latvia to do 4G tests. I refused to repair my phone and demanded to get new phone. Waiting for the answer
Also rooted my phone so no warranty for me. Changed carriers today and they are doing upgrades so stuck with useless service :/ but i think either it's something to do with root or software i dont think its hardware

Fuxas plz reply to.this thread when you hear back thanks
I dont think it is software, because I tried factory reset and it did not help.. Of course, when I get the results I will share them here.
If anything it's NOT the root because I am having this issue before I ever rooted it. My best guess it's the software and I've researched a lot about this problem, seems it's specifically related to some samsung devices and not only the Note 4.
Yup its a samsung problem and hopefully it gets rectified
Hello everyone,
I just bought a Moto G4 16 GB with Amazon Ads for my wife, but we are facing a very annoying problem: the carrier signal always dies after 24 hours give or take. We tested with a different SIM card and the same thing happened. When this happens the device only shows "Emergency Calls Only" and we have to reboot the phone in order to get the signal back.
So, is anyone else facing this problem? Is this really a problem with this phone in particular or every moto g4 has this problem? Should I return the device to amazon?
Thank you very much for any information you can give me!

No problems here since I got my phone last week and I have T-Mobile. You might have to check your apn settings with your carrier.

I tested the SIM card in a different phone and it worked flawlessly (I also use T-Mobile). The strange thing is that the phone gets the signal very well during more or less one day, after that I have to reboot to get signal again.
Well, this is probably a problem in the device. I already asked Amazon to send a replacement.

Try my APN settings to see if it helps, but locations very important

Thank you, but I just use the t-mobile network. In fact, my carrier is called campusSIMs and it is a MVNO that uses t-mobile network. So, my APN configs are a bit different from yours.
However, I didn't know about this mobile data thing. I didn't touch the developer options. Maybe, it can be a good idea.
Thank you!
It won't be your APN settings since that controls your data settings. If the sim is ok then it could be your phone.

I'm seeing a similar problem with the data portion of the network (also on T-Mobile). While I'm able to send and receive calls and texts, data doesn't work. There's no indication that it's attached to LTE or even 3G (just a standard signal bar with no other information). I moved the SIM card back to the old phone it was in and it works fine.
Things actually worked yesterday, so something happened overnight to break it.

That could possible be the APN settings. Although usually it's the opposite, they don't work at first then they update from the network later on. Most times the APN settings will set themselves but on the odd occasion they need to manually edited. I don't use T-Mobile but the APN settings are easy enough to find.

Sounds like you need to manually enter the APN settings. What you describe is exactly what happens when it hasn't loaded an APN.
I'm "kinda" having an issue here. It's a little different though; the phone works ok for a while (for me about 3 hours, usually), and then I still get an LTE indicator, but have no network connection (get errors in apps/"No internet" page in chrome).
Other times, I lose LTE and get locked in 3g (H indicator), and can only get LTE back by going to Settings/More/Cellular Networks/ and toggle preferred network mode to 2g or 3g, let it connect (H or E), then toggle back to LTE.
Motorola responded to a bad Amazon review requesting I post asking for help on their forums.

I'm active over on their forums also and it's good to post over there in case you ever want to do a soak test. They look at your posts there when they ask for soak testers. As for your problem, I've seen it shift back and forth if you are in an area between towers and one isn't sending out LTE. If it were that I wouldn't think you'd get it back so easily. There's an app, don't remember the name, that will show the towers and signal relative to your location, If might be interesting to look at that.
Having the same issue with radio. Just replied to your post, Kalash.
Ok, we got a new phone from Amazon and it has the same problem. So, I believe this phone does not work very well with MVNOs.
I notice that the problem is that the phone cannot reconnect to the network after losing the signal. For example, if you go to an area with bad signal and, eventually the signal vanishes, the phone will not be able to reconnect to the carrier network. The phone only reconnects after reboot. Airplane mode does not solve the problem.
This does not happen with my Blu Life One X. So, I think it is a software problem.

That's not true on all mvnos' apparently. My wife's phone is on Consumer Cellular, an AT&T mvno and it's never done that. We've been in a no service area several times and it's always connected immediately when getting service back.
