[Q] Signal drop - Nexus 5 Q&A, Help & Troubleshooting

Hi all
I bought a Nexus 5 yesterday. All good but today, the signal (that is, mobile signal) dropped and even with a flight mode on/off and re-scan for networks it did not pick up. In the end, I had to reboot.
It is completely stock 4.4.2 and I'm just wondering if this sort of thing is a common issue. The only thing I can think is I was definitely in a no signal "black spot" for maybe 15 minutes prior to the drop so it's almost like it "froze" and didn't want to pick up the network when it returned.
Thanks
James

Same exact issue, Sir.
It seems to be common, but I have minimized it by installing a custom ROM (I'm using the Cyanogen Nightlies) It is a known issue though from what I have heard.

I think Google will fix this issue on the next update,so don't worry,it's known issue,and enjoy your device!

set your "preferred network type" to 2G (even if "data enabled" is not enabled), you will notice that signal will be stronger

Thanks for the advice, guys. Like you say - as long as it's a known issue then hopefully a future update will resolve it.
For the "set to 2g only" advice - I only get the option of 3g or 4g? I already set this set to 3g only as I don't have a 4g data contract anyway.

Try flashing a different radio. It makes tons of difference on signal quality.

[Q] Nexus S 4G - DATA DROPS

I have been having this problem with both of my Nexus S 4G ever since I got them 2 months ago.
My data drops out frequently and takes a while to get back up. If I have 4G enabled, then I have to manually reconnect it as it will not do it on it's own. This happens inside AND outside. Driving down the road or just standing in one spot.
I've tried all of the radios (basebands) and about 7 different ROMs and versions.
I've refreshed the data profile, PRL, and even tried the roaming Verizon PRL and Hybrid PRL.
Gone back to stock and tried everything from scratch. Still the same problem.
Dallas/Fort Worth Area
Network: Sprint
Baseband: D720SPRKE1
PRL Version: P:40447
I contacted Sprint and they just told me to update the profile & PRL.....
Any suggestions?
I'm not familiar with the CDMA nexus s, but are you able to change APN's? At one point I'd be able to connect to 3g (I have an I9020A), but every minute or so it would drop, so I fixed up the APN's for my carrier.
iv had a few data issues
forcing PRL and account updates has fixed it a couple of times
i'v bought used phones that iv had
to have sprint force update
im on LC1
[altho i cant tell any significant difference here]
and my prl is 61086
[a business account]
im currently on slim
make sure your mobile network
is set to roam
is not set to home only
Am I the only one with this problem? As I'm typing this I lost data but still had 3 bars. I never drop calls but only data.
Help please. This is driving me nuts.

no
i go thru periods of it acting bizarre
try disabling wifi and reboot
this USUALLY fixes mine till wifi is re-enabled
and i drop the sprint connection a few times
riding around
it then fails to re-acquire the IP address.
look in your status and see if you still have an IP
when your data fails
fwiw
I never use Wi-Fi. Ever.
Happens while using both 3G and 4G.

4G is worthless here...
i dont even bother with the switch
does it do the same thing if you disable 4G?
I almost always have to use 4G (if possible) since 3G speeds are slower than dial-up.
I've tried rebooting and leaving 4G off, and still the same. Even tried going back to Gingerbread.

If going back to GB doesnt help, maybe it is hardware related?

In the original post, I stated that was one of the things I've done.
have you checked to see if you have an IP address
when data fails?
mine shows "unavailable" when it's wonky
and wont re-aquire till i reboot.
i'v seen this on 2 phones
off and on including on oem 2.3.7
fwiw

I have the same problems. From what I understand, its a problem with the hardware. I can confirm that's probably the case, because I've tried many different ROMs (stock, cm, etc...) and they all have the same radio issues (3g/4g and wifi)...
I have an NS4G in the DFW area and haven't seen the issues you're reporting. I'm currently on 4.0.4 with D720SPRLC1 baseband. Maybe I'm just lucky and have a good signal at work and home. It's very rare that I find an area of DFW where I don't get any data signal at all. Not sure what to suggest.
I get random drops too and i hate it. My 3g speeds are fairly good even above 1 mbps. Highest i ever got on 3g was 1.51 mbps
Mine will lose data if I'm in a coverage free area for an extended period of time, when I'm back in range 3g icon will show up just never reconnect. A reboot fixes it
Certain Areas
There are certain areas where I live that data just disappears. Although this is just a network thing I believe. It's weird though when I am driving it's like a 10 second drop and then all is good. Hope you get a solid fix!:victory:
Backup 4g Partition
REMOVED - was a bad idea.
I've actually replaced BOTH of the phones with brand new NS4Gs and they shipped with ICS.
Still the same problem.
This is driving me nuts. I was driving and trying to download Maps for the new phone from the Play Store and it took 6 tries. Kept saying RETRY.
What I've come to believe is happening is:
When 4G connects, 3G disconnects. When 4G drops (which is does frequently), 3G has to reconnect.
***Is there a way to keep 3G "on" in the background while 4G is connected?*** Maybe a way for the radio to transition back and forth?

Data Randomly dropping but signal fine

This is driving me nuts so if anyone has any ideas, I'm all ears
My Nexus 5 keeps dropping data. The Signal bar will still display full with H, but nothing will connect. If I'm running a ping it'll just stop and then eventually kick back in with 10000ms or something - Anything else i'm trying to do just plain won't connect. Could understand if I was losing signal but I don't seem to be.
Haven't had a chance to try the sim in my old phone yet to find out whether it's the network or the phone - was just wondering if anyone had experienced anything similar? :S

happening to me with sprint 3g on the unofficial cm 10.2. have to toggle airplane mode, not sure if its a CM thing or a sprint thing since i literally flashed CM the next day i got it lol
still happens
a few cm11 updates and almost a month later its still happening
I just started experiencing this same thing in the last week. Real frustrating part of it (beyond the obvious) is that there is no way to tell this is happening unless you are actively using the network at the moment the signal is lost. So if the phone is in your pocket and not being used, you'll really have no way of knowing whether you are missing important phone calls/text messages simply by looking at the display of the phone. Each time I only notice when I am trying to load a web page and it says I'm not connected to the internet (even though it shows that I have a strong LTE connection). Talked to both Google and T-Mobile about this and both basically pointed their fingers at the other. I'm pretty convinced that the problem is on Google's/LG's end though.
Getting my third RMA in the mail next week. Will likely take them up on their refund offer if this continues. Believe it or not, the intermittent loss of data isn't even the reason I set up the initial RMA (or the reason I sent back the first two RMA's I received).
I have this on both Three and GiffGaff in the UK. I also had this problem on my old Galaxy S2, so maybe it's an android problem?

[Q] Signal drop/No service

Just wondering if any one else gets this, sometimes my signal just drops out and I get no service.
Then it comes back it does not happen all the time, I live in a big city Leeds infact so signal is quite strong.
Just wondering if it could be a fault with the phone?
Thanks
I've noticed it happens to me too.

I was wondering if its my device because I live in the city and the signal is excellent around here, my other phone HTC sensation never had this problem. Was concerned it could be software/hardware problem possibly.

It is definitely possible.
I'm on AT&T and have the correct APN settings and have called AT&T with my IMEI. I have significantly worse signal than with my HTC One X. I am not comparing bars to bars, but rather where the signal drops completely. In places where I had low signal but still connected I now have nothing.
Straight talk using at&t Sim and notice radio drops..

T-Mobile on stock ROM i had my first signal drops.
I was fine (or at least never noticed them) from the time i got my phone (day one) without any drops here in orlando.
Drove over to Tampa/Venice Beach area this past weekend and noticed some drops. Had about 6 drops according to my battery stats in 2 days. i had good to excellent coverage the entire time except when it would drop comlpetely (outline of signal bars)
would connect in a couple seconds, but i noticed over night, it would drop for a pretty large amount of time (like 10-15 minutes at a time.)
Mmm defo seems like were all having the same issues, wonder what it could be

I had this issue too, and here's how I fixed it:
By default LTE is enabled, meaning the phone will periodically scan for a LTE network. If you're in a big city, you're likely to find one. Your phone will attempt to connect. However, it fails, meaning it will have to rescan the HSPA bands to connect back. That results in a few seconds of no service. Why can't it connect to LTE? Because by default, the APN is not the LTE APN, for Rogers at least. I'd assume AT&T would be the same. You can test this by dialing *#*#4636#*#*, selecting phone info, and selecting LTE only. You'll see that there is no service. I tested this in an area I knew had great LTE coverage, and that led me to the conclusion that it's LTE causing the signal drops.
So how to fix? Simple, just change your APN to the LTE APN for your carried. To do that go to Settings -> More -> Mobile Networks -> Access Point Names. If you're experiencing this issue on Rogers, change the APN field to ltemobile.apn. If you're on another carrier, you'll have to search for their LTE APN configuration.
After doing this your phone should start connecting to LTE again, and you won't get those annoying signal drops.

So yeah the next update will probably fix the issue. It's not so bad in the meantime, Lightflow sill notify you that your nexus has lost signal, and you still get the internet and incoming calls.
We're not alone. Supposedly Google is "aware" of the issue.
i've hcanged my setting from '4g' to '3g' to see if i notice a difference (hopefully will) then when 4g is released or i get a 4g sim, can move it back up
Yes, I'm having issues too. The real problem is the fact that I have a Wilson cell booster in my home (supposed to have up to 5000 square foot range) and my n4 had full bars most everywhere inside. With my n5 It shows 1 to 2 bars if I'm lucky and quite often drops to none! The only way to get full bars Is to stand right under the indoor antenna. Not impressed, and I sure hope this is fixable!

I hate to revive a dead thread, but I was wondering if people were still having problems. Once or twice during the day that I can see I will lose signal for a few seconds only to have it reconnect. Running 4.4.2 so the latest update did nothing to help the problem as far as I can see and I have messed with my APN settings. On AT&T. The Google thread seems to have a lot of different problems on the same thread, and it is a bit unclear if people are still having this problem. This is very annoying for such an otherwise spectacular phone. Thanks and sorry again for reviving the thread... :fingers-crossed:

Actually, there have been several threads on the issues associated with this (emergency calls only, missed calls, no signal,etc.). Ongoing and unresolved for some.

Appreciate the speedy reply. Hope Google gets on this fast. I also have LTE connection issues which has plagued both this and my original device so I am pretty sure its a radio issue. The phone loves to stay on HSPA+ even when there is a decent LTE connection: it's last in the pack to connect to LTE and first to disconnect when compared to others on AT&T.

My N4 with a combo radio sticks to LTE a tad better than my N5 with stock radio. Sadly, morrislee hasn't fiddled and combo'd N5 radios, and I'm not sure they've been tested and sussed out like the N4 radios. Citing the fact some with issues have flashed all the radios so far with minimal success means we wait for Qualcomm, after Google kicks them in the you know where.

Goofy Network Mode Switching - CM10.2

Hey guys,
For the past month, I have been fighting reception issues at my house, which isn't in the best of locations for cell service. With 3G/LTE enabled, I would get 2-3 bars and then the signal would disappear and stay that way. I used to be able to move the phone an inch in one direction and the signal would change. Then, the phone started developing an issue where it would drop the signal and not even try and pick it back up again until I cycled the airplane mode. It got so bad that I would cycle it and 10+ messages and voicemails would come flooding in and then the connection would drop again.
Well, I've played with multiple roms and am now on CM10.2 for a overall stable platform. I've tried just about every APN setting there is out there, and just last night I stumbled on a little trick. Normally when changing network modes, the change doesn't stick, and I have heard of this being common. Well, somewhere on the net, a guy mentioned to go under "Settings > Wireless & Networks (more...) > Mobile Networks > Network Operators and select AT&T when it shows up, then try and change Network Mode. Well, that worked great and now I have a very reliable EDGE connection through-out my house (4-5 bars). Even the connect to 2G only toggle works as well. At this point, I definitely prefer leaving it like this, since I get a very reliable connection and it looks like possible better battery life as well.
My question is, why does it do this? Is there a bug in the switching part of the network mode selection? I'm definitely ignorant to how that side works and any information for the subject would be fantastic at this point. It would be nice to have EDGE be a priority at my house, but out and about where 3G/LTE is available for the phone to properly pick it up. Are there external apps that help control such switching? Thanks!

Phone won't switch back to 3G from 2G

Hi everyone.
I'm having a strange issue with my internet connection. The phone connects to 3G fine, but whenever a go into a zone with no or bad 3G coverage (at work for example) and the phone switches to 2G, it'll sometimes stay in 2G even after going into a good 3G coverage area (at home). It doesn't happen every time, but happens a lot. The only way to make it switch back to 3G is by forcing "WCDMA only" through the *#*#4636#*#* menu. I could just leave it there, but then I'd have no connection at all when I'm at work, so I switch it back to "GSM auto (PRL)".
Usually, when the phone parks in EDGE, the network settings don't change, it stays in "GSM auto (PRL)" but it just won't switch to H. Today, though, it switched to "GSM only" by itself, which it had never done before.
I had this same issue with my previous phone (Huawei ascend P6), so I thought that it was probably a problem with the SIM card, so I asked for a new one but nothing changed.
I've seen a few posts regarding similar issues but most of them are very old and none of them have been very helpful. I hope someone can give me a hand here.
I have a Nexus 5 running Android 5.0 - No root
Thanks.
My phone sometimes gets stuck in 3g instead of handing off to LTE. I just toggle airplane mode on and off and it immediately goes to LTE. I know it's not a fix, but it is a pretty quick way to get your data back.
Data connectivity issues are by far the most irritating, considering how much it costs to have a device like this...

Thanks for the suggestion, but unfortunately that doesn't work for me. The only way is through the #*#*4363*#*# menu.
That sucks man.
I'm not sure there is a fix for this. Other than Google fixing it in the baseband. You would think that if the problem were in the source code that this would have been resolved by some of the devs here on XDA. I have had these problems for a few years, and on other devices as well.
I guess I'll have to live with it. Thanks anyway, man.
