[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's likely the radio software.

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.

Please Help! Nexus 5 Signal Issue(Not rooted)

I just got my Nexus 5 and I haven't root it yet. I notice that everytime I don't use my phone 5-10 minutes or hours, the signal will be lost and asking to reboot my phone. I can't tell when it's up or not. Sometime I take multiple reboot to get signal back up then it happens again and again. Is there a way to fix this problem without rooting? I don't think it's the Sim Card because I used it on my nexus 4 without any problem. or Just my device isn't good one. Please help!

I didn't root my phone yet, and I'm running 4.4.2 now. It's annoying to keep losing signal and it's back again. Even I have signal, I only have 1 bar compare to my old Nexus 4 has 3 bar or HTC one full bar.

I don't want to root it if its not solve this problem, I will have to return it.

There was an issue on 4.4 where it would randomly give you the "emergency only" message. You would have to turn on airplane mode and then turn it off, or reboot. But people have been saying it was fixed with 4.4.1/4.4.2.

The radio however sucks in 4.4.2 and was better in 4.4.1
perhaps we may see 4.4.3 to fix this?

I think it might be overall worse, but luckily I actually didn't see any decrease in signal in my area. I was really worried about it because I already have really bad signal in my house but 4.4.2 doesn't seem to be worse for me.

You guys forget to mention that Google cheaped out on the antenna to cut costs. Best you can do is to flash your carrier's radio over the generic one

I'm sorry, but you're dead wrong. SO much misinformation here. First off, there is no "carrier" or "generic" baseband. There is only one baseband. Second, antenna design requires a lot of engineering to maximize signal efficiency when you're dealing with interference from such things as wifi, nfc, Bluetooth, metal construction in the phone, etc.. I'm not sure what magical material you think that cell antennas should be made of that will solve issues?
I just got off of the phone with Sprint. They show that there is an internal memo on the issue and LG is aware of it. They will be pushing an update as soon as it's ready. Sprint will also be pushing an update for the Airave to help with the issue. The support rep told me that it is an issue where the wifi and LTE radios aren't playing nicely together and causing a conflict. That's why everything seems to work fine when 3G is set as a preferred network.

It's an issue that still hasn't gotten fix as seen here.

[Q] Any way to get WCDMA/LTE only mode?

Does anyone know if it is possible to get a "WCDMA/LTE Only" mode on the Nexus 5?
I basically want to stop the phone dropping to 2G. Recently LTE has been made available here and before that I used "WCDMA only" and it worked fine but that is no longer a viable option since I want to use LTE.
Thanks in advance

Can't you just switch off 2g dialing 3646?

I do, but I can use 3G to do this. I mean I don't want it to drop to EDGE.
The reason is, in Ireland the network provider Three does not have a 2G network and roams to Vodafone when it 3G isn't available. It then will not automatically change back to 3G. You need to manually select the Three network again.

you have no option then. you have either lte only, which gets you data and no phone calls, or you have lte/gsm. on gsm/lte, itll switch to whatever is your best signal.

Wouldn't it be easier to choose the operator manually?

It still jumps to vodafone when there is poor signal, even when manually selected. If there was a way of forcing it to stay with one operator or disable roaming completely, then that would do but there doesn't seem to be an option.

Not on the Nexus 5, as far as I'm aware. I think it just disables data anyway. I need to be able to disable roaming completely or restrict to WCDMA and LTE.

When looking in SlimKat (admittedly not stock), it is @fergietime suggests, national data roaming and would still allow the phone to roam to another operator when there was no signal on the existing operator - just with no data. However, I am not seeing a problem with that. It only roams nationally when there is 0 signal for voice on your operator?

Yes, but it happens me quite often due to certain places that I pass through. My operator does not have a 2G network at all so roams once it drops below 3G. The main problem is, I need to manually search for networks and select my network to get it back to 3G/4G. It's a network issue that Three Ireland refuse to acknowledge. It has been happening for 4 years at least. I am just looking for a workaround.

I see.
I am also on Three (UK though) so also have no 2G coverage. and yes, when it fails over to 2G (Orange in UK) it is a pain to get it back.

It's a very frustrating issue. It actually NEVER jumps back to Three and it changes to Vodafone nearly every time I go inside a Tesco or somewhere like that. I then have to search and wait for it to find networks so I can select Three. The only time it seems to work correctly is when using a device bought from Three or a Three rom, which obviously for the Nexus 5 doesn't exist. And even then people complain about it so it's a bit hit and miss.

Does anyone know if it is possible to add a "WCDMA/LTE Only" mode into a rom?

[Q] Roaming icon on 4.4.3?

So as everyone in here, i'm a early adapter. Once 4.4.3. was released yesterday I had to have it.
For now, I wanted the stock 4.4.3. installed and so I did, but now I have this one annoying thing, my phone keeps telling me i'm roaming.
I'm on a Dutch virtual network Telfort which uses the network of KPN, I think it has something to do with that. Anyone else experience this "problem"/"feature ?
Better yet, does anyone have a workaround to turn this off?
I tried enabling/disabling Roaming , didn't work. Soft reset, re-install etc.. None of those actions worked unfortunately.

No-one has this problem?

why is it a problem? its letting you know that its using a different carriers towers. unless you are getting charged extra, id ignore it.

Me to, also telfort. Have no clue what has changed...

same problem here
Same here, have to keep roaming on...
So no clue if I have 3/4G...
Any solutions??

This is a problem because a lot of people live close to the border. With roaming enabled, you connect automatically with a foreign provider. at high costs.

I've managed to solve it using a work-around:
Downgraded both the bootloader and radio to:
bootloader: hhz11k
Radio: 1.0.25.0.23
wipe(!)
Kept WiFi off & skipped Google account set-up
Saw an H instead of an R above the signal icon
Tested: it works
Data Roaming box is unchecked.

I have got the roaming icon too. I have got Tele2 which uses the network of T-Mobile. I noticed that this is the case since I updated to 4.4.3, so it must be new since then.

Does the carrier affect GPS performance?

So I was with several AT&T MVNOs using my Moto G3 (rooted stock). No issue. I switched to a T-Mobile MVNO. Later I noticed my GPS acting up. The GPS just couldn’t come up with a solution even whith good signal from several sattelites. Even when there was a solution, the error was between 40-100 meters. I thought there was no way changing carrier would make a difference. I almost trashed the phone for a new one. I switched back to the AT&T MVNO because of cell coverage issues (not GPS issues). But I noticed my GPS is working just fine once again. Does this make sense to anyone? How could the carrier make a difference?

Hi mate,
I am not 100% sure, but I believe GPS works without a carrier so I don't believe it would be affected by the carrier.
Have you tried looking for some firmware updates?

Most phones use cell towers and GPS for location unless you go into Location settings and change it to use only GPS, so if you don't have a good cell signal your location accuracy might be affected by that.

I was aware of that (strong signal in both cases), and of the AGPS which I routinely update. I can't figure it out. I even restored an old ROM when I knew the GPS was good, but the performance remained poor. And it was not a fluke as now with the AT&T MVNO the GPS remains good.
