Signal drops since 4.2.2 - Nexus 5 Q&A, Help & Troubleshooting

Hi everyone.
I owned a Nexus 5 one month ago, but unfortunately, it does not work as expected. On 4.4.0, I had multiple issues concerning network already (unable to switch to 3G networks only, very variable HSPA signal reception (from 4/4 bars to Edge exactly at the same place), ...). This issues were supposed to be fixed with 4.4.2 and most of them are, excepting HSPA signal which is still very weird. However 4.2.2 brings my phone another issue that I didn't noticed on 4.4.0 which is a very annoying and repetitive complete signal blackout (no reception at all (Edge/HSPA), even for emergency calls I guess). Signal drop can happen twice in an hour, twice in 10 minutes or may not happen at all 3-4-5 hours long. It's completely unpredictable. After a while, Edge signal (not HSPA !!) gets back by itself. If I wait 10-20 more minutes, HSPA comes back again, until it drops again.
Moreover, at phone boot, just after typing my PIN Code, it usually takes 2 or 3 minutes to catch a signal. Very slow isn't it ?
It does not seem to be a network issue, since my Samsung Galaxy S III doesn't encounter this using the same SIM card.
I read on Google forums and probably some XDA threads that I was not the only one to face this kind of network issues, even on 4.4.2, but issue description was each time a bit different from mine, thus I tought that it may be useful to post a new thread to describe precisely what was my problem.
Edit : My Nexus 5 is unlocked and rooted, but issue is present on untouched 4.2.2 also.
Edit 2 : http://forum.xda-developers.com/showthread.php?t=2525583 is probably my issue.
Do no hesitate to answer if you're thinking that you have the same issue (or kind of) or if you think that you know something that may help.
Thank you .

You can flash the radio from version 4.4 that helps a lot, I'm at work just search this forum the directions are here, it's easy.

^^ He appears to be talking about the link below. You can flash different modems that may work. Some people say different modems helped but I've had no such luck. I've flashed every modem available and still don't have data almost everywhere I go. I have data at home but that doesn't really matter since I don't need my phone at home.

Did you try flashing your carrier's specific radio?
Team Nexus 5 sucks

Were would one find the carrier specific radio? I'm on T-Mobile but have only found the thread with modems. Nothing carrier specific.

Thanks for your answers. Unfortunately, flashing different modems does not seem to help .

i've read, the .15 is good with t-mobile.
i'm testing it today too. my problem is not only a signal drop, i have only edge too and my modem won't switch back to umts or hspa(+).
i'm in germany with t-mobile (congstar).

[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.

[Q] HTC One S, CM11, and poor data/cell signal (if any)

Hey everybody:
This is kind of a last gasp for me. My HTC One S suffers from the usual that you read about - "Preparing SIM" messages, constant error reports on bootup, random reboots. I honestly hate the phone.
So I installed a custom ROM. I unlocked the bootloader via HTCDEV, then I used the 12/20/13 CM11 (KitKat 4.4.2) with the 12/15 GAPPS.
The phone worked OK except now I was able to see what I've read about, and probably unknowingly experienced with the stock ROM, and that is the phone constantly flipping between Edge, 2g, HSPA, HSPA+, etc.
So, I decided to try a new radio. Did it a million times on my old G2. In order to get S-OFF to update it, I used the RLL to bring it back to stock Jelly Bean, then Moonshine to set S-OFF, SuperCID'd, and restored it with CWM. Then I installed the 1.20.x radio and at that point, all heck breaks lose with the data network connectivity and even cell signal. I might have no cell or data signal. I might have a cell signal with Edge. If I get up and move, it might go to HSPA, then I might lose everything again. This is much more pronounced than what I witnessed when I first installed the CM11 ROM.
I've tried reflashing the original 1.13 radio and it's no better. I went back to the 1.20 radio and even wiped and reflashed CM11 and GAPPS from scratch. Still very inconsistent data connectivity, so I'm not necessarily convinced it's the version of the radio because they're both pretty darned bad including the original version.
Has anybody been through this and gotten it straightened out? This is strange that even going back to the old 1.13 radio doesn't seem to help.
Thanks for any ideas...
Type: HTC One S, S4, S-OFF, SUPERCID
HBOOT: 2.15.4444 (Moonshined)
Image: CM11 (12/20/13 - 4.4.2)
Radio: 1.20.50.05.16_10.31.50.08L
Who is your carrier? If it is TMOUS you will probably need to make some adjustments to your /system/build.prop file. When I flash a new ROM I have to make the following additions/changes before my data connectivity is stable:
Code:
pm.sleep_mode=1
ro.ril.hsdpa.category = 24
ro.ril.hsupa.category = 6
ro.ril.hsxpa = 4
ro.ril.radio.svn=19
ro.ril.fast.dormancy.rule = 0
The setting "ro.ril.fast.dormancy.rule=1" probably already exists in the file, so it will either need to be edited or removed. The other settings should not exist.
The changes that actually allow the phone to maintain a data connection (as I recall) are "ro.ril.radio.svn=19" and "ro.ril.fast.dormancy.rule = 0". "pm.sleep_mode=1" allows the CPU to completely power off, and the "ro.ril.h*" settings set max speeds for different data connections. I'm going off of what I've culled from various posts and forums, so I may be off the mark on some of my descriptions.
Here's one post briefly talking about these settings:
http://forum.xda-developers.com/showthread.php?p=48276115#post48276115
You will need root access and your /system partition will need to be remounted as read-write to make the changes. Ask or search if you need help with those. Of course if you're not on TMOUS, then I have no idea...
Yes, T-Mobile US is my carrier. There's another thing I found. If it go into the phone's testing facility (*#*#4636*#*#), I notice that it's set to WCDMA preferred. If I set it to WCDMA Only and give it a few, it does go to an HSPA/HSPA+ connection. However, that setting appears to be lost between restarts.
What I don't get is that when I first flashed the CM11 ROM, I at least had the intermittent E/2g/3g/HSPA connections. How, if I go into that testing facility, it is stuck on Edge (and more consistent since my last flash). I will read the thread you provided a URL to. Thanks very much!

OK, I did these build.prop edits. Unfortunately, they've gotten me nothing. Then I went and investigated them a bit more and tried two other minor changes to build.prop (one of your parameters and added another). I'm still stuck on the Edge network. If you do a lookup, you'll see plenty of others. I think this phone is pretty much worthless - as it's been from day one. It will be my last HTC phone. By contrast, my old G1 and G2 are still working. There are tons of reports about One S phones suffering serious issues like this.
I appreciate your help and certainly, if anybody has a eureka moment, I'd love to hear about it. For the time being, I'll most likely see about getting my old G2 reactivated. Others have reported that the only way they've gotten this fixed is sending it back to HTC under warranty. Mine is out of warranty, which is the only reason I decided I'd do it. It was such a bad phone, I had nothing to lose. The next one I buy will most likely be the Moto X.
Thanks again for the help. I absolutely appreciate it.

Sorry I can't be of more help. I'm still fairly new to this phone, but I quite like it. I suppose I've been more fortunate than others in that I haven't had any real problems with it.
It's not a problem and I'm grateful for you trying. The information you provided was also interesting from a learning perspective.
I reran the RUU on it, just to see if it would make any difference. This made it so I USUALLY have 2g connectivity, but that's as far as it goes and it's not good enough. I have lost that at times, but for the main part, it's consistent with 2g.
T-Mobile is sending me a new SIM to get my old G2 reactivated. While it's only about a quarter of the One S speed, it'll suffice. Unfortunately, the SIM it had couldn't be used because too much time had elapsed since the phones last use. That should be here Monday and that particular phone was WAY more tolerant of different images and radios (knock on wood!). It's currently running a Jelly Belly image of Android 4.2.2 (if I remember), so this should be interesting.
As for my HTC One S, I'll most likely give it to my son to use for games and media. With nothing more than 2g speeds, it's worthless to me. This phone has been a complete and utter piece of garbage since the day I got it. It's funny that my excellent experience with the T-Mobile G1 and G2 by HTC was my reason for buying the One S over a Samsung model. Now that phone is the reason I won't be getting another HTC. Strange how that works.
Again, thanks VERY much for the help!

Weird, I had a desire z (same phone as g2) and it had really bad reception while holding it. Would lose all signal in the house. All my other phones used have been fine and pretty well equal - nexus one, desire hd, one s, my girlfriend's iPhone are all about the same.
This summer at a cottage my sister gs3 had no service all week, same network and the one s and iPhone
4s both could squeak some signal if you didn't touch them. A slight edge going to the iPhone most of the time I think.
Probably either a radio issue with that phone on your provider or defective hardware?

It's not the provider (T-Mobile). My wife's Samsung has 4g here in the house - no issues. I took the One S out and had 2g everywhere. It's the phone.
I'm also guessing it's most likely the radio, as in a bad chip. Once you try to burn a new firmware into it, it finishes it off. Don't get me wrong, I'm certainly no engineer. It may or may not be that, or may be WAY more involved. Some people said the only way they got it fixed was by HTC replacing the main board.
The phone was a POS even before installing a custom ROM. Random reboots, constant startups with messages asking if I wanted to report the errors to HTC, random instances of NO data connectivity and then a message saying the phone is "Preparing the SIM card". I finally realize now that the occasional drops I would get while working remotely in Mexico (using a Movistar SIM) were most likely a result of this thing losing it's data connectivity while "Preparing the SIM card." The issues with this phone and the fact that it was out of warranty were the only reasons I took a chance on installing a custom ROM.
I'm sorry that I most likely sound like I'm ranting. However, I've searched all over and found SO MANY issues with this phone, that there's no way they should NOT have been recalled. Even T-Mobile told me there were many reported issues with these things. Both companies failed their customers.

Here in Canada we don't even have 2g on Telus, Bell, virgin mobile and koodo (I am on Telus), so the several phones that seem to have network problems on 2g or switching back And forth only have those issues on Rogers/fido or the small carriers like wind.
A guy I knew from highschool years ago works at fido and I remember him telling me last year this phone had some reception issues.
When telus had this phone on their website still they had pretty well all 5 star reviews. So my phone would probably be a piece of **** on a 2g/3g network too luckily they work perfectly on hspa only.

Interesting. It's nice to have the option in the case of there ONLY being Edge/2g/3g service available, but not to be stuck on it when HSPA is there.

True, at least around here though the amount of area without service for Telus/bell or Rogers seems to be pretty equal. So I'm happy not to have the issues with switching between 2g, 3g and LTE. It's hspa or hspa I guess.

[Q] What is a modem and can it solve my reception issues?

hey guys
i tried understanding by myself what exactly the modem does in a cellphone but since the term/word modem is so common it was hard to get results for the exact thing i want to understand.
my reception issue is this:
im from israel in a network called "Golan-T", using my previous phone, a nexus 4, i had great internet access and cell reception, 90% of the time i had 4/4 bars and the internet was H+ with speeds of 5-10Mbps (normal speeds here in israel)
now on my nexus 5, im there is a constant issue with the above
the bars go from 2-3 RAPIDSLY, meaning they could switch between 1-3 bars every 2-5 seconds, which i suspect not only means a terribly low signal, but also destroys my battery life
2nd, for some reason i NEVER get H+, but i assume the icon for + just might no be there in the nexus 5, but i get the same every few seconds change cycle with 3g (which gives me speeds of under 1MBps and i cant do ANYTHING not even google now searches) and H, which also changes every few seconds.
yesterday i drove for over an hour with Waze and didnt have internet for even 1 second.
so - after the above long story
i was wondering what could be a solution and someone tossed my way that the modem could be the issue and that it can be flashed, so i was hoping i could get some guidance here
ty!

The modem handles all cellular connections much like old internet dial up modems. Its what connects y you to your phones provider.
When it's referred to on xda it's most commonly talking about the radio firmware. Something which can improve or worsen signal depending on what has been changed in the revisions to it.
However your problem sounds more like an antennae issue than a modem problem.
Usually the radio only gets updated with an ota or factory image flash.
If you want to test you can flash the various factory images from Google which also contain the radio's or you may be able to find a collection of radios here on the forums to flash.
The factory images are flashed by using the flashall.bat included in the download. (Bare in mind this will also erase all data on your phone)
The radio images in the forums will usually be flashed in the bootloader with fastboot using the command
Fastboot flash radio xyz.img
Where xyz is the name of your downloaded image

[Q] No signal strength all of a sudden

Hello,
I bought my Nexus 5 on the 11th of December 2013 and it had been working flawlessly ever since. Since last week, I started noticing the occasional signal drop and I'd be out of cell reception but would usually be back up within no time. However, yesterday, out of the blue I'm travelling on the highway and my signal strength disappears never to come back again. I've tried the following:
- Restore old backup (including EFS)
- Went back to stock from PA
- Upgraded to the latest radio
- Took back cover off to see if anything was wrong but found nothing.
- Tried another SIM card
Nothing worked. My SIM card works fine in another phone. Everything else such as WiFi and Bluetooth works flawlessly but I just don't get any reception.
This is very disappointing and I have my fingers crossed hoping someone can help me with this since I didn't plan on getting a new device for at least another year especially after paying $520 USD for my phone here in my country.
Thank you for looking.

Flash stock firmware with fast boot. If its the same, its a carrier issue....call them to see. Or its hardware failure.

Then it is a carrier issue....cause on Telus in Canada....never had an issue with any radio version. ?
telus would have a stronger overall signal but uses AWS band for lte which is different than mobilicitiy 3g aws...
I'm not disagreeing.... Just saying its the carrier....not Google.

are you saying mobilicitiy is purposely weakening their cell signal cause they are almost bankrupt ?

Just saying that unless many have the issue with the phone or radio, then its an issue.....if not, it isnt .
So in this case, it leaves hardware or carrier....assuming a stock flash didn't help.
If flashing another radio helps the OP...awesome!! But the new radio does work fine for the mass majority.
Hope it does work for him tho!

Wrong signal strength reporting on G920i?

Weird issue I'm having on a G920i. In Settings -> About Device -> Status, the signal strength is being reported incorrectly. When I first boot the device, it will show accurately and will vary from -90 dBm to -100 dBm when I am at my house, which is consistent with every device I've ever owned. However, after 30-45 seconds, it will start reporting at "-113 dBm 0 asu" and it will simply stay there and will never change, even as I move about. The number of bars in the signal strength icon on the status bar will even change, but in the Status menu, signal strength simply stays at "-113 dBm 0 asu" permanently. Connectivity seems to be fine--I have no problems making calls, browsing the web, etc. The signal strength in the Status menu simply seems to revert to and stick at 113 dBm 0 asu with no explanation or other impact on the phone.
For what it's worth, I've tried both the New Zealand and Singapore AOD1 firmwares from Sammobile.com. Same problem on both. I'm on AT&T in the U.S.
Anybody else seeing anything like this?
Yes it seems both the g920i and g920f all have this problem. Every single device. Please get in contact with Samsung about it, the more people that complain the more likely it will be fixed.
@mupet0000 & @phositadc I've seen you guys in a few forums talking about the Galaxy S6 SM-G920I signal issues... Mine is the same! Swapped 2 phones already and they have awful lte reception... I was hoping a different modem/baseband would help but it looks like it doesn't....plus a few soft reboots as well what's going on? Have you guys experienced any reboots? Can this be fixed with a software update?
OK checked mine and its yes your right. -113 in status however if you type *#0011# in your dialer you'll see the better reception reported. Interestingly this did not happen when I was on the Cricket towers(At&t). I just switched to T-Mobile and I now have the -113 status. My speeds are great but I can't side-by-side compare the radios to anything to know if there is a real problem.

No reboots here. I flashed the aod3 modem last night and things seem a little better on AT&T. On the aod1 modem, I was not getting LTE in a bunch of places that I've always had LTE before. I know the g920i has frequency support for AT&T LTE bands, and I do get LTE, but I must say so far the experience has not been as good as other LTE phones I've had. Not sure if that's the modem firmware to blame or the hardware itself. Probably firmware.

Hey all, I'm in the UK and I have the SGS6 edge on the 3 network here. I use my phone for tethering at all times as I do not have wifi in the house. with my SGS5 before this I could easily run my PC , Tablet my son mobi and his gaming PC all at the same time with no issue. The S5 would run a full signal and load very quickly HD content.
My brand new S6 is disapointing singnal wise from straight out the box. I noticed my signal level fluctuating up and down but very rare dose it show a full signal level. and as for teathering I am finding it very hard to live with.
I will be suprised if Samsung sort this out with firmware. I just had a 150 MB firmware update yesterday and my signal level is the same.
I remember my Nokia N96 having this same fault, and although it was all over the internet back then, Nokia did nothing in all the firmware updates I had. I was going to sell my pristine 7 month old S5..... but I think I will hang on to it for now.
Hey guys, I am on the latest OTA released by Samsung (AOE3 built May 7th) and the problem is still not resolved. LTE signal still awful and LTE signal strength still -113. So far so bad. I have contacted Samsung again, and tomorrow I have a phone call with their support where they will remotely access my phone so I can show them the problem. I will show them and see how it goes, and I'll report back here.
I will make it clear to them that the signal strength is worse than my 2 year old S4, and I will demonstrate the incorrect signal strength value to the support agent. If they tell me it's a non issue or they make some silly excuse instead of investigating, I will simply sell the S6 and get another phone.
This is a huge issue and I'm disappointed that there aren't many people noticing this or reporting it to Samsung. The more popular the S6 gets, the more people will notice that their old phone holds a better signal.

I think it is a widespread issue... I always have 1 bar lte and under my signal status it say - 113dbm which is zero service... It never moves... I'm gonna try custom rom and see if that help but it obviously a antenna/modem baseband issue... Also someone mentioned it could be because the Galaxy S5 uses Cat 4 lte and the S6 uses Cat 6.....its very disappointing! Hopefully it gets fixed or I'll return to the S5...i really want to like this phone..... But Samsung is making it hard to
I don`t think there is anything wrong with the signal. even if I only have 1 bar the phone is perfect during calls and my LTE/4G download speed is even over the provided speed my carrier provides, I think it`s just a bug that it`s showing less signal then what it actualy has.

This is true. It's simply a bug that shows the wrong signal strength - mine shows -113 but I'll have 3 bars so that makes no sense. However, if you ARE getting a bad signal, that is a different issue altogether.
(btw I started a thread about this already several weeks back)
Spoke to Samsung on the phone, they didn't need to remote access my phone to see the issue. They had an S6 in their office and they told me they saw the signal at -113dBm just like mine. They say they have passed this onto the relevant team and hopefully it will be fixed in an OTA and I should stick to the United Kingdom BTU firmware (the correct firmware for my region).
We will see if this gets resolved. They definitely know about the problem now and have seen it with their own eyes, so I'm hopeful.

Ok.. Thanks... I already read through that thread too... Been trying to figure out if it was just me or alot of people..... Seems like the 920f is getting more updates that us.... 920I......The latest is AOD3 right? Today I'm gonna flash a custom rom for 920f and see if there is any change....
*edit* just checked Samsung live update... AOE3 was just released for 920I for TTT I guess is a country called Trinidad and Tobago... But that is the firmware I've been using.... Hopefully this will help... Let Ya guys know
*edit #2*...ok guys just updated to AOE3.... Bars still show low but the signal status is working and it's showing that I have a better signal than with *#0011*... The - dbm and asu is now extremely close to my S5... So in conclusion the signal is strong it just doesn't show it in the bars like previous Galaxy's
