[Nexus 6 Q&A, Help & Troubleshooting] erismaster:
While you may be right about the throttling, I believe it would be more related to the Nexus 6 showing up as an unrecognized device. I forced my N6 to 3g and just ran a speedtest and got 1.20 Mb/s down and 0.61 Mb/s up. I ran another test on LTE and got 11.09 Mb/s down and 6.56 Mb/s up. I'm starting to think that maybe there was an issue with Verizon's LTE network last night rather than throttling. I did a reboot and another speed test to make sure that switching to 3g then to LTE didn't improve the situation and that speedtest result was 4.65 down and 6.65 up. I switched back to 3g and then back to LTE and ran another speedtest and saw results of 15.79 down and 7.48 Mb/s up. So switching to 3g and then to LTE has had a positive effect for me. Can someone else try to replicate this?

So maybe switching to 3g and back to LTE after a reboot will help some? I'll report back in a few hours how my signal and battery are doing.

Well got the phone in the mail today all I can say is it socks I'm gonna give it a day in the wild but can't see it working. Had it out a bit tonight picked up 4G in spot where I no I can get it but had to force it. It held it for awhile but no Internet most times it was 1X with no data. I'm in a crap signal area but I get mostly no signal. Very disappointed it's probably going back for a flip phone lol. Sorry for rant but it's so disappointing.
[Nexus 6 Q&A, Help & Troubleshooting] TheAmazingDave:
I've been noticing this a lot with mine too. I believe it happens when switching wireless bands/signal types. As has been noted, it never drops a call and voice is crystal clear. I haven't been actively using data when it happens though, so I don't know if I'm dropping internet or not.
[Nexus 6 Q&A, Help & Troubleshooting] wooddale:
I think voice may be a little better I rode around with Advance signal on so I could actually see what it was doing. It wasn't good like I say I'm gonna give it another try tomorrow but I'm very doubtful. I also have a Note 4 there is no comparison the Note is probably the best android phone I have had to date. I'll post tomorrow with my findings.

After testing a lot yesterday seems like it can grab the radios good enough but even though it says 3g or 4g it has no internet. I don't think it has much to do with the bars either . I use an app called advance signal and you can see the bars disappear but the signal doesn't change. There is however still the problem signal is dropping. What to do?

Got the update now signal bars still doing same thing but seems yo be holding 3g and 4g better. Seems to be about the same as my 2013 motox was except grabs more 4g.
[Nexus 6 Q&A, Help & Troubleshooting] Arikara:
Does anyone have a exclamation point in their signal bars? works fine on wifi and exclamation point then disappears. But when you shut down wifi you can't access your data? It says your offline or no internet connection? I flashed Liquidsmooth 1/23 update and from there the issue went from there???? reset APN, reflashed, reset, ?? Lost need help!!!!
[Nexus 6 Q&A, Help & Troubleshooting] wooddale:
I'm stock and have same problem but always get data eventually. Getting a replacement phone to see if its any different.
[Nexus 6 Q&A, Help & Troubleshooting] steve841:
IMO... It's a Motorola thing.

Wacky signal meters going back to my Razr days.
[Nexus 6 Q&A, Help & Troubleshooting] wooddale:
It may be a Motorola thing but its for real you can watch your dB's fluctuate as well.I'll no more when I get replacement to compare.
[Nexus 6 Q&A, Help & Troubleshooting] GFinger240:
I don't know if anybody else was having the same problem I was having, but my signal would change from having signal to disconnected every 30 seconds or so. I confirmed this by booting into safe mode and looking at the status page. The service state would keep bouncing from in service to no service along with the signal reading. IT hit me to check the APN's, and it was set on MetroPCS instead of TMobile for some reason. reset the APN's to default, and it seems the problem is gone. I was missing a lot of calls and texts didn't want to send right away. I just changed the setting, so I'll know through the course of the day tomorrow if that was the fix. Again, don't know if anybody else who is rooted with custom roms is having the same problem.
[Nexus 6 Q&A, Help & Troubleshooting] antman8969:
I had the same issue with my rooted Sprint model (using Ting). For some reason, disabling USB debugging and restarting the phone fixed the issue. It also seems to stop SuperSU from working as my Power Toggles plugin can't restart my phone anymore, but I need service more than root right now.
[Nexus 6 Q&A, Help & Troubleshooting] wooddale:
I'm on Verizon I got another phone same deal. I thought you were missing signal when it happens but I'm not sure it does. I'm in a crap signal area most times so its hard to tell. When I am in a strong signal area even though bars go away signal is still there try an app like Advance Signal and it will tell you. Again I'm on Verizon don't know if your problems are same but it seems like it is common to all carriers.
[Nexus 6 Q&A, Help & Troubleshooting] Namolas:
For whatever its worth I never did get to the bottom of it on Verizon. Was getting up to 60% time without signal, texts failing, unable to complete calls and everything, and we have spectacular Verizon LTE where I live. Eventually went into the local store and tried to get help after I had tried everything else I could think of but they wouldn't help because its not a Verizon phone (and because Verizon are complete A-Holes.) I left the Verizon store in a huff and drove down to the AT&T store and ported our 3 lines over. Haven't had it happen again since switching. Nexus 6 maintains 0% time without signal on AT&T.

Personally I think Verizon has marked as many of these as they can in their system and purposely feeds them a sh!t signal. All IMO of course.
[Nexus 6 Q&A, Help & Troubleshooting] wooddale:
Lol you might be right. Like I said when I'm in my crap area its hard to tell. I have noticed when I get in a strong signal area it works well. One thing I have noticed though sometimes it gets like a brain fart when switching bands and just locks up I need to do a late recovery to get it back. I don't have the option to switch here its either Verizon or US Cell. US Cell is only good in Wisconsin. I wonder if anything is gonna change when they finally get the Nexus.
[Nexus 6 Q&A, Help & Troubleshooting] collegencmc:
Okay let me start with what I'm on:

N6: 64gb blue

Rom: Stock

Rooted: Yes

Any other modification: No, only think I did was unlock and do chainfire su root.

Network: VZW

I have had this phone since Dec with no issues other than random reboot every so often.

Now to the problem I had, I went out to the middle of MO for a weekend get away (on Feb 14th). The whole time I was out there it showed 1x even though I was still getting LTE speed. Didn't think much of it until we moved further into the hilly parts of MO were I lost service. Thought it was just where we were at, and thought it would come back once we got back to the hotel we were staying at. It never did. It would say "No Network found" only allow 911 calls.

Spent the next 4 days working With VZW with several trips to the store, and talking to tech support. They made sure my IMEI was not blocked on their side. We used several sim chips, they would all do the same thing, quickly connect then disconnect and go back to no service.

So I did a factory reset, still didn't help. I finally did a fastboot flash of 5.0.1 stock again, this fixed the issue. Until I used titanium backup to restore my sys setting. Then it would drop and not reconnect after the reboot. So I did fastboot flash again and it hasn't happened again since last Thurs Feb 19th. I just restored my app's again to make sure it wouldn't fail to connect over the weekend, and rebooted several times. No issues so far, but I called Motorola and they are RMAing me a new one, because I don't have any trust in this one anymore. They are out of 64gb ones, and they will get back to me in a week.

Questioned to anyone who has gotten a RMA from Motorola:

Are their "like new" replacements okay? I got a few from them when I had my droid x, and they were crap. So I wasn't sure if that is still the same for the N6 or not. I have a feeling its not, but just wanted to get other peoples input on that process.

Thank you for creating this thread, and for everyone's time!

Edit: Had the same issue network wouldn't work, however WIFI, Location, Bluetooth would.

Not sure whats going on with this phone, its still spotty at times.
[Nexus 6 Q&A, Help & Troubleshooting] wooddale:
Think your phone is jacked that's not a signal no signal problem. Anyway about the RMA I did the credit card deposit thing so I could compare phones. I stayed on them like fly's on poop. They told me they were out of stock I said that was in acceptable. I ended up getting a brand new in the box phone and all I had to to was just send them the old phone only back so I got the extra charger and cord. When I was quizzing them about what kind of phone I would get back they said they dont fix phones the phone I would get would be one that was used for testing at Moto I find that hard to believe. So if you got the time to stay on them and you get the right guy you can get a new phone. There not bad guys just hard to understand sometimes but if you tree them like a bud you can get what you want.
[Nexus 6 Q&A, Help & Troubleshooting] collegencmc:
Hey wooddale, Thanks for letting me know and the tip! I have been in contact with them to get me a new phone. Hope to get it soon as I don't know when the current one will start the problem again.
[Nexus 6 Q&A, Help & Troubleshooting] wooddale:
Good luck.Be demanding but nice.
[Nexus 6 Q&A, Help & Troubleshooting] wooddale:
So how is everyone doing with new OTA signal wise? Not to good here I flashed the new radio yesterday and not only did it not change signal no signal but it was worse dropped signal a couple times was in a place where I normally get a signal and got nothing. I'll find out more today I have already switched back to old radios. Maybe it will be better if I do the O T A instead of just radios but it never has before.
[Nexus 6 Q&A, Help & Troubleshooting] cam30era:
Carrier? LTE or voice?

Fwiw: I'm on AT&T. In very weak signal areas the 5.1 radio (flashed ota) has better LTE reception for me. Voice is basically unchanged, or possibly a little worse in weak signal areas.
[Nexus 6 Q&A, Help & Troubleshooting] wooddale:
LTE on Verizon voice unchanged
[Nexus 6 Q&A, Help & Troubleshooting] ChristianLife21:
I just RMA'd my Nexus 6. i cant spend $750 and not have a working phone. :( just not gonna work.

with my Galaxy S5, i could always use data and voice at the same time. cant on the nexus 6. HD voice or VoLTE whatever, wont work for me because i cant accept or make calls to any landlines, only cell phone to cell phone work.

So sad to see my Nexus go. but it brought a multitude of problems for me.
[Nexus 6 Q&A, Help & Troubleshooting] wooddale:
Not in same boat as you dont mind not having phone and data. Im disapointed in OTA didnt do anything to help made it worse. Volte is way ahead of itself like you say can only talk to other Volte. Im gonna take the note out tomorrow maybe its Verizon jacking things up
[Nexus 6 Q&A, Help & Troubleshooting] aewig:
I just initiated a replacement as well. Given that it isn't appearing to be too widespread (in terms of number of users), crosses carrier boundaries, and has been an issue in the only three iterations of Android available to the phone - I'm hoping it's a weird hardware issue.

I'll try to report back if the replacement helps when it arrives next week. Some people say they are going to get a replacement but never return to say if it fixed it - not too helpful :)
[Nexus 6 Q&A, Help & Troubleshooting] wooddale:
Unfortunately it won't help signal no signal even 5.1 doesn't help.
[Nexus 6 Q&A, Help & Troubleshooting] krash2k77:
WOW motorola and google. 750 bucks for a phone that the radio doesn't even work well?

SO, I am on straight talk att towers and my phone does the same thing i can watch it go up and down in and out, it doesn't seem to interrupt me but i am not happy with it, my s4 stays solid i gave half that for it when i got it new "weird story i wont go into" so anyway google locks down a phone not being able to use the leds built in and just says piss on you and your customer care we dont care. Motorola will never get a dime from me again if this keeps up.
[Nexus 6 Q&A, Help & Troubleshooting] ChristianJay:
Was having this same problem and fixed it. Go to Cellular Networks/ Network Operators and click on "Verizon" (or anything I suppose to disconnect your current connection), that disconnected the network, then I went back and selected Automatically select network at which point it searched for a minute and then, TA-DA, connected me with great strength and showing LTE where as before it was only 3G. It changed my preffered network type to LTE/GSM, but I switched it to LTE/CDMA and the phone now works great. ﻿
[Nexus 6 Q&A, Help & Troubleshooting] slider112:
Just curious if any of the new 5.1 builds or radios (95R or 98R) have solved this problem for anyone? Specifically the signal dropping suddenly to zero bars, without actually losing connection, then back. Signal (DBM) would remain constant, but ASU would read 99, which technically only means "unknown signal", not actually dropping signal. Haven't seen any posts about it in a while here.
[Nexus 6 Q&A, Help & Troubleshooting] wooddale:
I've been on 95r went back to 5.0.1 radio sucked for me gonna try 98r shortly. I never noticed ASU just signal db its hard to say but it looks like it holds on to it but really doesn't have it if it only cuts out for a short time it recoups with out you even noticing other than the bars disappearing. How ever if it stays off long enough you will drop signal
[Nexus 6 Q&A, Help & Troubleshooting] ChristianLife21:
2 days of cell history here. i compared with the Galaxy S5 history sitting right next to my Nexus. S5 was just about all green.

I've since returned my Nexus to Google and am done with the Nexus. :( it disappoints me to say that, but i cant spend 750 bucks on a phone and it not work good.

I tested mine. i missed calls, and dropped calls. my data connection drop from 7mb download to 10k then go back up to 5mb down. then drop to 0k. then go up to 6mb and drop to 30k. the signal loss is substantial.

BlissPop rom is a great rom. it has a speed monitor that you can add to the taskbar next to the cellular data icon.

this is how i measured my signal loss while watching the speed disappear.
[Nexus 6 Q&A, Help & Troubleshooting] slider112:
Yes, this. I also believe tower switching or band switching is what is causing ASU to drop to 99 (unknown) and thus the signal bars to "drop out". This doesn't happen often, but it also doesn't have to necessarily be fringe areas either. The switch can occur anywhere, even in strong signal metro areas, if you're traveling around enough. Signal isn't actually being lost (dbm stays constant), but it's being reported that way during the hand off, thanks to the 99 asu report. Would be nice to be able to revise the way that android reads that and not drop bars for it each time. Either that or have the ability to force to a particular band/tower to avoid the switch.
[Nexus 6 Q&A, Help & Troubleshooting] BlackKnight23:
I've exchanged the phone for three different new phones. I've had three different Sims and reset default network to LTE preferred and it had correct T-Mobile APN settings. I still have the issue. I've had the issue on 5.0,5.0.1, and now 5.1. Google or Motorola needs to admit and fix this issue.
[Nexus 6 Q&A, Help & Troubleshooting] BlackKnight23:
Just curious the factory images that Google post LMY47E is older than the T-Mobile OTA LMY47M Correct? Why is the updates still running 95R radio setting if we have a new bandwidth enabled?
[Nexus 6 Q&A, Help & Troubleshooting] kenvan19:
I've been reading around for a few days and haven't seen anyone posting anything quite like what I've got going on but maybe I've missed it.

I work in an Army Medical Clinic on base. I was on Verizon but had terrible service (all of the hospital/clinics are known for having crappy service) so I decided I'd switch and see. Initially, my N6 was fantastic and I had service inside (albeit usually 1x) and then starting a few days ago the radio would simply stop. There are two variations of what happens but both have the same net result and are fixed by a reboot: 1) It shows either 3G or HSPA but if I try to use any data it errors out with "Not connected" 2) It shows simply a "!" on the bar and won't connect. I've tried messing around with APNs, done 2 factory resets, tried *#*#4636*#*# (though it actually doesn't bring up a menu), and most recently rooted so I could potentially try another radio if needed. I vaguely remember having issues on my Nexus S wherein the radio would die. If I remember correctly the issue stemmed from a time when the radio went without a signal for X amount of time and then simply was not able to reconnect regardless of available signal. The workaround, if memory serves, was to toggle on Airplane mode if you knew you were going to be without service for any length of time and I bring this up because I've been using this workaround on my N6 with success. If I toggle it on before I enter the building and leave it until I exit, once its back off voila! Service. The problem is that while doing this I've missed several important messages that I *should* have been able to recieve and in the military "phone issues" doesn't really work as a valid excuse. I'm far outside of my trial window and to be honest, I do really like the N6 (aside from the obvious) but this is getting to be unacceptable.

Has anyone else seen/read/telepathically received reports of anything similar? Is it possible my phone just crapped out?
[Nexus 6 Q&A, Help & Troubleshooting] longshot21771:
I am on Sprint and have had just as much problems with the N6 as everyone else. . I was originally on stock rooted and one night the ! appeared beside the signal bars and would not leave. I tried the *#*#72786#*# to refresh the config and it would come up to configuring data and voice box and nothing would happen. Ended up having to have Sprint push it and it worked. Later I ended up installing this rom http://xdaforums.com/nexus-6/development/rom-android-l-5-1-v1-0-0-t3075065 staying close to stock rom as much as possible. Then setting the LTE (Recommended) setting back to Global, reason is...around here for Sprint there is no LTE service as of yet. So far my speeds have been more consistent and battery life was never an issue with mine. Still the update device config and update prl won't work, it just sits there saying wait, nothing happens, till I call Sprint and they do it on their end.
[Nexus 6 Q&A, Help & Troubleshooting] kenvan19:
I forgot to mention what I'm running/what I've tried.

I was previously stock, locked, unrooted but have since rooted with stock with no change.

The only successful fix is a full reboot and airplane mode circumvents the issue. I have tried changing the APN, force changing the network, changing the preferred data, using *#*#4636*#*#, toggling off/on cellular data, toggling off/on airplane mode (once the radio is dead) and a hot reboot (which only results in a no sim error).

The only thing I can think of is that since it only happens at work it has something to do with the network here specifically. Though, I haven't had signal problems anywhere else so its difficult to tell. Its a bit conspiracy theory-y but I've thought that perhaps the issue is related to an IMSI faker like a sting ray but even that is hard to support since its only in the hospital/clinic. As I'm sure is evident I'm damn near my wits end here with this and any input would be much appreciated.

[Nexus 6 Q&A, Help & Troubleshooting] patmw123:
Does anyone still have this issue? I'm not referring to the ! issue many people are currently facing as of late, but I'm referring to the 99 asu issue where the signal bars drop and asu signal drops to 99, but doesn't actually affect data connection or cell signal. I have had this issue since I purchased my Nexus 6 back in November. It is still the only issue I have had to this day. I have tried every build/radio combination possible but don't know what could potentially be causing this. Has anyone found a potential fix? It is super annoying.
[Nexus 6 Q&A, Help & Troubleshooting] ryanallaire:
If calls and data still work and it's just an annoyance than it has a slim chance of getting fixed, more than likely there's hundreds of lines of code that would have to be gone through and they probably just won't do it...
[Nexus 6 Q&A, Help & Troubleshooting] patmw123:
It just seems like it's such a widespread problem that Google would certainly have the resources to fix it.
[Nexus 6 Q&A, Help & Troubleshooting] wooddale:
Think about it I think if they could they would have. I think it is what it is.
[Nexus 6 Q&A, Help & Troubleshooting] patmw123:
Maybe so - but I still don't see why Google would be completely unable to fix it.
[Nexus 6 Q&A, Help & Troubleshooting] wooddale:
Im not an expert here but I have had a ton of smart phones. My experience has been when it doesnt get fixed in the first or maybe second ota its probably hardware or just cant be fixed. Like you say it is not wide spread it is a problem some people who are in good signal area just font notice it or its just not a problem for them so they dont care. Also you have to understand us tweakers are in the minority of people that own the phone.
[Nexus 6 Q&A, Help & Troubleshooting] patmw123:
Yeah I have had a ton of smartphones as well - which is why I don't understand why it would be an issue that Google couldn't alleviate. You're probably right with it not getting fixed since we have already seen multiple OTA's, but I don't see how it could be a hardware problem as it is essentially a visual issue as opposed to a function issue. Us being "tweakers" doesn't really have anything to do with it in my opinion. It has nothing to do with rooting or unlocking the bootloader or anything of the such. This has been an issue since I received the phone and I only run stock rooted. At first I was 100% completely stock and that was when I initially noticed the issue.
[Nexus 6 Q&A, Help & Troubleshooting] Ryjabo:
I am on T-Mobile and after having the phone for nearly 4 months, I can say without a doubt that the only time I ever have this issue (signal bars displaying as discussed in this thread) is when I am in an area that gets crappy signal. The building I work in, for example. When I'm outside, it's fine. So to me, it's not a big deal.
[Nexus 6 Q&A, Help & Troubleshooting] wooddale:
When I said tweakers I kind of meant people that know whats going on I would bet 3/4 the people that own the phone dont even know there is a problem. As far as Google goes I dont know but there must be a reason maybe not hardware but something major in the software thats not worth there trouble to fix. Were probably gonna buy the next one anyway lol.
[Nexus 6 Q&A, Help & Troubleshooting] patmw123:
All very true and all good points
[Nexus 6 Q&A, Help & Troubleshooting] backdown00:
Just got an unlocked n6 and using it on verizon - same issue as here. My question is, is this a hardware issue, have others tried to replace the device and the replacement still has the issue? My phone does jump around a lot but it never actually drops service completely. I can still get great speeds with LTE with 0 bars and call quality and still perfect.
[Nexus 6 Q&A, Help & Troubleshooting] wooddale:
Same here it is just what it is I have went through all the OTA,s and no fix so I figure hardware or they just don't care they know it happens.
