I just did. And eventually it died. It seems like if I leave it on the preference of LTE, then I get the exclamation point. If I force it to be 3g only, then I get the situation where the icon claims it's 3G, and the signal looks good, but I have no service.

I have the same problem with sprint, they couldn't give me a solution either...
[Nexus 6 Q&A, Help & Troubleshooting] rbox:
Did it just start, or have you been having it for a while? Has anyone tried using the radio image from 5.0?
[Nexus 6 Q&A, Help & Troubleshooting] mnsportsguy1978:
Just since 5.1 I believe, at least didn't notice it before...
[Nexus 6 Q&A, Help & Troubleshooting] YankInDaSouth:
Been having signal issues as well lately (T-Mobile) and now that I think of it it's very closely timed to when that Google Connectivity app showed up! Just disabled it to see if I notice a difference
[Nexus 6 Q&A, Help & Troubleshooting] rbox:
I've disable mine and so far so good... but who knows. What version do you have? I see I have A.1.0.1, but on the play store I see an update for B.1.3.3. It doens't show up in my list of apps to update, but if I do a direct search, it shows up as an update.

---------- Post added at 04:59 PM ---------- Previous post was at 04:56 PM ----------

Of course I had to just go and jinx it. It just got the problem again. But I did also reenable the app for a short while before disabling it again. Maybe it's related...
[Nexus 6 Q&A, Help & Troubleshooting] YankInDaSouth:
Not sure if the version I was running assume that it was the latest, but it uninstalls updates before disabling ...

Seems like the affected users are on T-Mo. Have you gents considered tower maintenance/upgrades?

I'm on T-Mo as well. I've had a few similar instances over the last few months, but the problem resolves in the areas it's happened, and now the reception is better.
[Nexus 6 Q&A, Help & Troubleshooting] rbox:
For a whole week? It's defintely a signal strength issue, I just can't figure out why. The way the building I work in is laid out, there is a hallway along the edge, and I get great LTE there. then I walk into the room a few feet away from the window, and it's fine. Then I go behind my cube wall, and it starts to get weaker. Than as I move a few feet away from the wall, it drops to 3G.

Also, it looks like disabling Google Connectivity Services didn't do it for me. I had rebooted with it disabled and evenutally it still died.
[Nexus 6 Q&A, Help & Troubleshooting] jbdan:
Very odd. I've been having some weak LTE signal issues at home, but only at home. Wife's S6 stays connected to LTE -110dbm here while my N6 hunts and switches back and forth between 3G and LTE. Started happening about 2-3 weeks ago. I've been hoping it's T-Mobile, not my phone
[Nexus 6 Q&A, Help & Troubleshooting] midwestkel:
I've had that happen as well.

Tried that and it didn't do anything for me.

It just started this week for me. I've had 5.1 for over a month and haven't had this issue before Monday.

I've tried disabling the Google Connectivity Services (v B.1.3.3) app and that did nothing for me as well. I also switch my APN to IPv4/IPv6, it was on IPv6 only but it didn't make a difference. I also did a test by taking the phone to a location that I know has strong LTE while it have the ! icon and it would not reconnect to any network. I tried toggling airplane mode but it didn't refresh the cell/data radio either. After rebooting I had full LTE service.

I talked to Tmo reps and they didn't see any maintenance on the towers in my area but they opened a ticket for me.

It seems like something is bugging out while it jumps between LTE/4G/3G and then the radio crashes. At home it's solid LTE and I don't have any issues.
[Nexus 6 Q&A, Help & Troubleshooting] jc0187:
Yea but its frustrating when T-Mobile acts as if there isn't a problem. That they have NEVER heard of this issue before. I've called 3 dozen times to T-Mobile customer service and each and every one of their service specialist say the same thing; that I am the only person on their network experiencing these issues.
[Nexus 6 Q&A, Help & Troubleshooting] duradrinx:
Verizon let me exchange for an S6 today. I couldn't take this lack of support and service any longer.
[Nexus 6 Q&A, Help & Troubleshooting] meh3884:
Were you beyond your exchange period? I asked T-Mobile for this exact exchange and they offered me a $300 trade in value and an extra $100 credit toward an S6. And this was their "best" from a manager in their "loyalty" department. They actually want another $300 from me to get a different phone that actually works! I am now filing consumer protection complaints hoping to get my full $699 + tax back.

Here are my answers:

1. Yes, this does affect my data connection

2. Yes, this does affect my voice calls

3. I tried toggling airplane mode, turning off data connection but found rebooting the phone works.

I am using a Nexus 6 on TMO network in the Portland/Vancouver area. I am on TMO's 5.1.1 LYZ28E. I am noticing the "!" it more since getting LYZ28E and enabling WiFi Calling and selecting WiFi preferred.

I also noticed, while rebooting, my N6 is telling there is no SIM card inserted in. I would say about 10 to 15 seconds later, I get the signal meter outline then I got service. That happens with or without being connected to WiFi
[Nexus 6 Q&A, Help & Troubleshooting] h4xdaplanet:
Can confirm that there is no fix with the latest update, problem happens when in HSPA coverage or when forced to HSPA connections. I plan on writing an email to executive support at T-Mobile to see if we can get some response. Nothing back from Googs on the forum page.

Unfortunately this issue has left me with only one choice if I want reliable cell service. Switch phones. Luckily I'm on JUMP1. Tried the GS6, boo. Gonna give the LG G4 a shot. Still have my N5 in case. Gonna miss vanilla android and ff speakers :( (at least until Oct/Nov - next Nexus release)
[Nexus 6 Q&A, Help & Troubleshooting] meh3884:
Doesn't it piss you off you have to pay out of pocket extra to get a phone that works? There shouldn't be anything wrong with the one you have. No way I am paying anything out of pocket for a new one. They sold the phone that doesn't work, even if this problem is Google, T-Mobile owes me a $700 phone that works on their service I pay $100 for every month.
[Nexus 6 Q&A, Help & Troubleshooting] jbdan:
Heck yeah it pisses me off. Just ask my wife! But I don't have time to go through it all. I used too when I was younger and had no kids, not now :sly: I respect your fighting it and believe Tmo is in the wrong if they don't address your issue to your satisfaction. Wishing you good luck
[Nexus 6 Q&A, Help & Troubleshooting] Unclean009:
Thanks Mark. Do you have any updates on the situation over there that you can provide for us? It's been almost a month with this issue and it's starting to infuriate me.
[Nexus 6 Q&A, Help & Troubleshooting] meh3884:
I hear ya, it's been a damn nightmare at this point. More than ten calls to support. I have filed consumer complaints with my state and the BBB. Waiting for T-Mobile response. It is amazing to me that they will let me and my $100/month walk away over a $300 credit on my phone. They not even offering me the trade credit I could get by selling on eBay or what they will sell the refurb for. They're bent on getting more money from me and making a profit on my dud trade in.

All I asked was an even exchange for a comparable/equal value phone.
[Nexus 6 Q&A, Help & Troubleshooting] jbdan:
They should do the right thing and give you a new device of your choice at ZERO charge. I'm hoping they see the light and hook you up :thumbup:
[Nexus 6 Q&A, Help & Troubleshooting] h4xdaplanet:
So I ran adb logcat with the phone in HSPA/3g mode and waited for the fail to happen, which it did. One thing I saw that might be related is this line

E/QC-QMI ( 455): qmi_service_send_msg: timeout error for conn_id29, service_id=1, client_id=31

E/QC-QMI ( 455): qmi_service_send_msg: timeout error for conn_id29, service_id=1, client_id=51

When I google conn_id29, there are posts on xda related to connectivity issues (specifically cell network) and some show related messages.

I am able to trigger these to happen by going to the test screen and triggering the turn radio off button. about 30sec later this shows up in the logcat. I couldn't find exactly where the issue started happening - I'm not a dev and wading through tons of logs isn't my specialty.

I have reached out to T-Mobile's executive team for help with this. What is hilarious is when they tried to call me, my phone was stuck without a connection. Gonna try the dev M build and see what happens hah

I'm doing the same thing on T-Mobile. I'm using my Jump1 early. The other night my wife, 8 months pregnant, fell and was on the ground over an hour. With no way to reach me on my cell because of the ! . She had to reach me through my work number, which added an extra 30-40 minutes to me finding out what happened. I called T-Mobile and told them I was finished with them. They kept making excuses and sending out replacement devices, only to have the problem return. So...they upgraded me to the Jump1 and made me eligible foran early upgrade. I just wanted a full refund, but oh well. It sucks you put your trust in a device/cell phone provider and they let you down.

I also upgraded to Android M yesterday, and it just happened to me this morning.

NOTE: At home, I am not seeing this issue. I am getting "!" only my work, since TMO is using the towers from AT&T and my works internet connection for their data (which AT&T is as well). So I already had crappy mobile data.

[Nexus 6 Q&A, Help & Troubleshooting] h4xdaplanet:
They offered to let me get a new phone on EIP with a 30 day return, no restocking fee (the rep seemed to know that the Nexus phones are not the same as any other). At the end of the thirty days, I could either send the new phone back or send my N6 back and they'd wipe my N6 EIP (450ish dollars). Seems like a pretty good offer when it isn't really their issue. She also said that she would run up my info to her Google contact, and called back asking for more information so I'd like to think something is happening here. For now, I just sold my n6 and am going to use my n5 until this clears up. No use holding onto a device with a declining value when it will just sit in a drawer.

Update

I decided to try something I should have done before posting... I reinstalled the stock N6 5.1.1 image from T-Mobile(1). There's some problems with their batch script but the instructions at ibtimes(2) helped resolve the install issue. The key was getting the bootloader and radio images updated before installing CM12.1 (it doesn't include radio for Nexus devices).

[Nexus 6 Q&A, Help & Troubleshooting] meh3884:
I had a voicemail from the Executive Response Team yesterday. Not sure if it is a response to my BBB complaint or just my account in general; I won't hear back until Monday. Your offer doesn't seem that great to me, though - it seems similar to my offer where they were willing to give me $400 toward a new phone for my N6 (my N6 is paid in full).

I'm not sure whose issue this is; whether it is all Google or a Project Fi interference that neither Google nor the carriers are dealing with. I wish I understood more about it, or that Google/carriers would say something/acknowledge a problem. I've been watching the Project Fi threads and noticed that no one in the Seattle/PNW area is getting an invite yet - seems interesting when people all over the country are getting them and Project Fi is supposed to have perfect coverage here in Seattle. Tells me Google does know there is a problem, at least in this area. It's really disappointing. Everyone could be saved a lot of grief if someone would suck it up and say there is an issue and we're working on it.

Forced 3G only working.

It's now been 2 days since I changed settings to 3G ONLY and the "!" problem has gone.

On Monday (I'm in UK - so forget all the posts about local cell towers/cities etc) I'll change it back to 4G and see if the problem returns within 30 mins.

What is really pissing me off is the absolute silence from Google and Motorola about this.

I'm 101% convinced it's a software OTA problem as everybody started to get the problem, around the world, at about the same time and the chances of hitting the same hardware problem, around the world, at the same time is ... well, winning the Lottery would be easier.

I spoke with the Executive Response Team today in response to my BBB complaint. They called me back timely, she was sympathetic although I don't think entirely sure this was T-Mobile's problem, they agreed to allow me to return my Nexus 6 with all packaging and accessories, and upon inspection, give me a credit for the full value of the phone. I can use the credit to buy a new phone, pay my bill for several months, or request a check once it's applied. This shouldn't have taken so long, but I'm happy to finally be done and to be able to stay with T-Mobile. Now I need to figure which phone I want to get instead.
[Nexus 6 Q&A, Help & Troubleshooting] contradude:
I had been experiencing this issue very badly and was just about to try and warranty out my nexus 6 and jump asap and I was able to partially (and possibly full resolve the issue). I flashed the full T-mobile 5.1.1 system image (all partitions), rerooted and reinstalled Chroma rom. I then set my T-mobile APN to IPv4. since doing all of this I had zero ! point moments at home (in LTE coverage) and I'm testing in a HSPA+ coverage area. will update you guys if I lose connection again. just updating my radio baseband didn't do it, one of the other partitions did it.

I have an unlocked T-Mobile 32g N6 on Verizon if that makes any difference and hence why I decided to try out the VZW modem.

[Nexus 6 Q&A, Help & Troubleshooting] nhizzat:
I've been experiencing this as well on Verizon running rooted stock 5.1. Reception, in general, has gotten worse especially in areas with weak signal. What's worse is that reacquiring a signal once entering a known area for strong signal takes entirely too long, much longer than just a couple of weeks ago.

I thought this was an isolated issue with my replacement N6, which I received a couple weeks ago, because I didn't notice this behavior with my original N6. It only started once I activated this replacement N6.

I'm going to see if I experience the same thing with my G3. I'll report back in a few hours.

I cleared apn type and got "!" for a couple seconds. I then got LTE back. I will run it this way tonight and see if the "!" comes back. I will report back tomorrow.

Edit: SSDD. I continued to get the "!" after clearing apn type. Odd thing is it seems like I have no problems with service at home, but when I get out to the airport, that's when the "!" stays popping up regularly. Seems like it happens more when service is spotty.

For my N6, changing the APN has worked for me. Like what useltonm said, at home it works just fine, but when the service is spotty it happens more.
