I FOUND THE SOLUTION! :laugh:

I tried with all radios, all apps, everything and here the solution:

Install Xposed + Intelli3G Module (you can find it in PlayStore)

the problem lies in changing networks (Lte to hspa) and this module fix it.

In Power Saving network mode set GSM Only (2G)

In Fast Network Mode select LTE/WCDMA

The exclamation signal dissapear and the connection its OK (If the exclamation signal appears, only switch to power saving mode, to fast mode)

Working on my nexus 6 with Pure Nexus 6.0.1 rom (with latest modem). :good: :good: :good: :good:

I get the error message that Xposed is not compatible.

How did you manage to get it to work? :confused:

Never mind, I see that you went with a custom ROM.
[Nexus 6 Q&A, Help & Troubleshooting] nickoArd:
wich rom do you use? I Recommend you Pure Nexus ROM or CHROMA (im on purenexus)

Xposed is compatible with lollipop and marshmallow (Custom ROMS - Rooted)

Go to this link: http://xdaforums.com/showthread.php?t=3034811 and download this version: xposed-v79-sdk21-arm.zip and xposed installer.... flash the .zip and install the APK.

Tell me if this solution works for you

If i helped, hit the thanks button :good:

New to xda and nexus 6. I'm having the same data drop issue as most on Sprint. I'm on 6.0.1 unlocked and not rooted. If I root m is there a good ROM to fix this problem or am I better off going back to KitKat and rooting. I see there hasn't been complaints of the problem on KitKat. Thanks in advance.
[Nexus 6 Q&A, Help & Troubleshooting] Backtoback1:
thanks nickoArd

i have some questions :

- i must rooted my phone nexus 6 for install xposed ?

- and before install xposed i should install custom recovery and open the bootloader?

- can i do that without root the device (i'm not want to lose the waranty )?

thanks al ot
[Nexus 6 Q&A, Help & Troubleshooting] nickoArd:
For install xposed, your phone must be rooted. After this, you can install xposed.

whatever you do, you will lose your warranty.

without root, you can do nothing.

Change radio's. That solved my problem when it was happening to me. ROM can also effect it sometimes.
[Nexus 6 Q&A, Help & Troubleshooting] rbox:
Well this makes me feel better that it's not just me and it's not just my phone. I downgraded to the 5.0 radio today and when I'm back at work on Monday I'll see if it helps. I too have tried APN, airplane, everything. One thing I found that did work, was dialing the 4636 dialer code and hitting the "turn off radio" button. Unfortunately only once did it switch to "turn on radio". The other times I tried it it never switched back to "turn on radio" and I wasn't able to turn it back on. If things aren't better on Monday I'l be calling tmobile up as well and mention that I've heard of multiple people having the same problem and it all started at the same time.

I am having the same problem with my Nexus 6! I was hoping my phone wasn't messed up. The problem started this week and I am in Phoenix AZ.

Same exact problem here! My friend also has it. He is on Sprint and my self Verizon. It's not carrier specific.
[Nexus 6 Q&A, Help & Troubleshooting] mnsportsguy1978:
I'm on sprint in Minnesota with the same issues
[Nexus 6 Q&A, Help & Troubleshooting] TaintedByte:
Also in Arizona (Mesa here). Started having these issues about three days ago. Phone was perfect before then and since I didn't change any software on it I was worried that it was a hardware issue. I'm glad seeing this thread since that's not the case (unless all of our phones are catastrophically failing in unison.)

I went into T-Mobile today and told them about it, the reps told me they actually had two other people come in the past couple of days with the same issue. One of the guys that works there also pulled out his N6 and showed me he's having issues too. It seems like a widespread issue.

Coincidentally, the issues started when Google announced Fi.
[Nexus 6 Q&A, Help & Troubleshooting] jc0187:
Yup, I'm in Phoenix as well. T-Mobile too. Its a frustrating endeavor, having the ! appear next to my signal bars. No data when my coworkers are downloading videos from Netflix or YouTube on Verizon or AT&T.
[Nexus 6 Q&A, Help & Troubleshooting] meh3884:
Just came here to start a thread on this topic. Glad to see other's are already talking about it.

I am curious as to why folks believe this is a signal strength issue, given it just started recently? I live in Seattle, and while I had intermittent signal issues since I got the phone in late March that were quite annoying, just this week on Monday I began having prolific problems, especially near my home in North Seattle. I previously got consistent LTE signal here, despite the occasional appearance of a ! icon for a few minutes. Now I have it almost exclusively at home, and I get the ! at work right in downtown for up to 20-30 minutes at a time. I, too, show a good signal quality in SIM status whilst the ! appears. The signal quality does seem poorer compared to my Nexus 5, which also ran Lollipop. I did not have any signal issue, intermittent or not on the 5. Still, I do wonder if this new issue that seems to have started for everyone this week is completely or partially separate from the occasional !/poorer reception issues, i.e. related to a recent app update.

Has anyone else begun researching the Google Connectivity app? I haven't yet tried disabling it (I currently am trying a factory reset back to 5.0.1) I went to T-mobile on Wednesday and they were clueless, told me they hadn't heard of this issue and are sending me a warranty replacement. I am torn on whether or not to just sell the new replacement and get a different phone altogether, as it doesn't seem a new device will solve the problem. I want to love this phone very much, but it seems rather plagued with issues.

As a side note, is anyone planning to attempt trying Google Fi? I am curious to see if these signal issues are well resolved by the T-mobile/Sprint combination.
[Nexus 6 Q&A, Help & Troubleshooting] rbox:
I just assumed it was a signal issue because it only happens for me at my work and I am constantly switching back and forth between towers and 3G/H/LTE. I just flashed back to stock 5.1 M and was testing on Thursday. I had disabled the connectivity app and I still got the dead signal eventually. I was still on the original version, not the updated one from the play store too. So my issue wasn't related to an updated connectivity app.
[Nexus 6 Q&A, Help & Troubleshooting] cam30era:
I'm not optimistic. Look at post #55 here > http://xdaforums.com/nexus-6/general/project-fi-waiting-t3097939/page6
[Nexus 6 Q&A, Help & Troubleshooting] meh3884:
Fair enough, and that is pretty disappointing. I can't help but feel like all the work being done for Fi might have something to do with the ! issue we're suddenly seeing, but I can't make a logical connection between the two. BTW, I am deflated to find when I downgraded to 5.0.1 and setup as new device/no personal apps, it took only a few minutes to go back to getting the !. Google connectivity services is not compatible with 5.0.1 so it seems, like others, I can eliminate that variable.

12 Google apps updated immediately upon setting up the phone before it failed to keep updating the others. There were no interesting apps that got updated that would point to causing this problem (it was maps, keep, docs, etc), but it could have been a system app like play services that isn't listed in the play store as recently updated. I may factory reset again and prevent any of the immediate Google app updates.

I have until Wednesday before my warranty replacement arrives to decide if I will try the new device or get a different one and sell the replacement.
[Nexus 6 Q&A, Help & Troubleshooting] meh3884:
FWIW, I spoke with Google support chat today. Despite the correlation with Google Fi service and the somewhat similar problems early users are seeing there, the support tech was very apt to blame this issue on T-mobile, especially after reading this thread which I linked him and seeing mostly T-mobile users. He had little advice, as expected, and nothing I hadn't already tried with T-mobile. He told me I should trust that T-mobile said there are no issues on their end and the warranty replacement should work right.

I am really not expecting the new device to work properly, but as of right now I am missing several phone calls and text messages each day/night I am at home. I will be requesting a bill credit from T-mobile as the phone has been little more than a wifi tablet for a week now. I would sure feel a lot better if someone - T-mobile, Motorola, or Google acknowledge a problem here.
[Nexus 6 Q&A, Help & Troubleshooting] meh3884:
Your tech was more tedious than mine. The guy I spoke with didn't try to make me redo anything, excepting making me put in my address to T-moible's coverage map. I am losing hope as well. Eventually they'll fix it, but how long are we supposed to wait? I am further infuriated that I told T-mobile I could not make or receive phone calls with my phone, but they thought it was fine to go ahead and UPS Ground me a new one, which is in the middle of taking 7 days to get here. I just missed the phone call for my building for a package I really, really needed and paid for Saturday delivery for. I'm about ready to scream.
[Nexus 6 Q&A, Help & Troubleshooting] Q9Nap:
I've been having the same issue as well, although it's been intermittent over the past couple weeks.

As it has started happening only recently, it is doubtful that the issue is hardware related.

Can't help but think the issue is network related, and possibly/probably a result of integrating project fi.
[Nexus 6 Q&A, Help & Troubleshooting] va2azerik:
My job where I have the problem is around 40th st and Roeser. I wonder what changed?
[Nexus 6 Q&A, Help & Troubleshooting] jbdan:
Mine has gotten worse with time unfortunately. I got my N6 the day it launched in tmo store and its been perfect signal wise up until few weeks ago. I've just recently missed a few calls and SMS. IMO something is going on with tmo network and the N6 (in my case)
[Nexus 6 Q&A, Help & Troubleshooting] JohnCorleone:
Damn it! I was going to get the Nexus 6 on Thursday. I am on the HTC One M7 and this started happening to me in late JANUARY! I can't make or receive calls on LTE, I lost 3G altogether and I have to toggle to 2G to make and receive calls. Its obviously a T-Mobile issue. I called in early February and they said that they were doing "network improvements" in my area that may take a while. I am currently in Costa Mesa, Southern California. Now I am going to demand a new SIM and to test the calling before I leave the store on Thursday...of course I will probably encounter the issue on day 15 with my luck. Its not a device specific issue guys. It could be Fi if Sprint people are having it as well. If anyone on Verizon is having it, I am lost because only T-Mobile and Sprint are initially a part of Project Fi from what I have read.

I've been experiencing this myself on T-Mobile since last monday, and just factory reset to the newest build LMY47I (coming from LMY47D)... Reboots kind of worked and occasionally airplane mode switches throughout the week... Only been about 12 hours since the flash but I havent had any issues since.

Also should note that I'm in Phoenix as well...
[Nexus 6 Q&A, Help & Troubleshooting] meh3884:
Do you have T-mobile? I am on LMY47M, the T-mobile OTA 5.1 build. I will definitely try the factory image LMY47I if you're saying its helping solve the problem.

Me too - on Verizon

Two of us here on Verizon and we thought we were going crazy!! This just started for us while vacationing in Orlando, FL... but continues to occur randomly back home in Washington, DC.
[Nexus 6 Q&A, Help & Troubleshooting] lesbox:
Yes, im on T-Mobile... And I'm not sure if its a solid fix, but no issues in the last day... And previously it was bugging out every couple hours if not more frequently.

So hopefully it's resolved?.... No way to know for sure without some more usage. Might not hurt for you to give it a go.
[Nexus 6 Q&A, Help & Troubleshooting] meh3884:
Right on. Doing a backup and trying now. Fingers crossed. Just spoke with my local T-mobile shop on the phone a little bit ago, I can't even to convey the issue; they really aren't getting it. I encourage everyone to hammer their carriers and Google until someone admits an issue.

In any case, wish me luck.
[Nexus 6 Q&A, Help & Troubleshooting] coldconfession13:
Yea I just had this issue earlier I rebooted which fixed it. For me it was coming off WiFi to cell data I had the ! And had to reboot. I'm on Verizon
[Nexus 6 Q&A, Help & Troubleshooting] meh3884:
Sounds like most of us on T-mobile are getting the issue consistently since about May 4th, even after reboots and resets. Let us know if you see it come back again, I'm curious if other carrier's are seeing the same constant connectivity loss or just sporadic problems with the similar but temporary ! symptom. For the first month I had the phone with T-mobile, I got occasional ! symbols and connectivity loss but they only lasted a few minutes, also when coming from Wifi or a no signal area (like elevators). Now I get the ! for most of the day since last Monday, and the reboot only works for a few minutes. Even when I have connection, I am never seeing LTE anymore, despite it previously being a solid LTE signal here in N. Seattle.
[Nexus 6 Q&A, Help & Troubleshooting] mademan420:
Seems to be a pretty wide spread issue, but not all. Also not just the N6. Seems to be affecting other nexus devices as well. Saw one reviewer mention that he hasn't had this issue since going to 5.1.1

[Nexus 6 Q&A, Help & Troubleshooting] meh3884:
Good, really glad to see this getting some attention beyond some disgruntled XDA members. I wonder if this is why there has been a delay in announcing 5.1.1 for the Nexus 5/6.

Also, total no-go for me on LMY47I. I was hopeful - was able to do all updates and app downloads over LTE which I hadn't seen for days. Then gone.
[Nexus 6 Q&A, Help & Troubleshooting] JohnCorleone:
Ironically, I was going to Hawaii for my birthday in January. I put my phone in airplane mode and when I landed, it started happening on my M7. I have tried ALMOST everything... different firmwares, hboots, radios, etc. The ONLY thing I haven't tried is the last full T-Mobile ROM RUU that was released but that only brings the device to 5.0.2. Unfortunately, the M7 is no longer going to be getting updated so I know that its time to get a new device. I was hoping that the amount of radio bands available might help avoid the issue (maybe roaming on AT&T towers if necessary) but if the majority of problems are on T-Mobile and not isolated to one device, I am confident that a solution will be found. Hasn't someone from T-Mobile been tweeting about another upcoming update that enables WiFi calling and texting in the near future?

Edit...I know that it was a Google Services Framework update in the Play Store that conflicted with the HTC software on the M7 and M8 that started the problem with those devices in late January
[Nexus 6 Q&A, Help & Troubleshooting] mademan420:
So with that being said, do you think its more than likely a lollipop bug since its happening across multiple devices as well as different software revisions? I dont have an N6 yet but I do have a Note 4 still running 4.4.4 so I cant really comment on this issue in regards to my device.
[Nexus 6 Q&A, Help & Troubleshooting] TaintedByte:
I'm glad AP picked up my tip (and thanks for backing me up in the comments! Most people thought it was a generic issue.)

As far as that build, I can also report it didn't work for me either :(
[Nexus 6 Q&A, Help & Troubleshooting] meh3884:
Yeah! I hope I didn't come across as tearing down other folk's problems, just wanted to convey the gravity and specificity of our issue relative to moderate annoyances like the momentary "!" when turning on data, needing to toggle airplane mode, etc, and to clarify over all the anecdotes about other phone's occasional problems last December (lol). Anxiously waiting for some kind of official response.

edit: Just spoke with Google support chat again and linked him the AP article. He said he consulted with his team and database and said they have not received enough reports to "bug" the issue. Again, I encourage everyone to take a minute and report problem to Google. It seems they will just give us a "deny, deny, deny" line until they can't ignore it anymore.
[Nexus 6 Q&A, Help & Troubleshooting] JohnCorleone:
OK question for you all since I don't have the device yet. Do those of you who have VoLTE have the option to turn it off? If so, try turning off VoLTE and "OK Google" voice command and see if that sorts out your issue. It did for a few others on different devices like the M8 and another I can't remember

Well, since the car battery is dead and I've got nothing to do but watch hockey, I'll keep trying the new stuff. These fixes didn't solve it for me. I already had the VoLTE stuff turned off, and turning off the Google now voice commands didn't help. Thinking of trying Chroma's ported 5.1.1 ROM for kicks.

OK, now I am getting scared to get the N6 on Thursday.... I have been dealing with this problem for months and it only gets more frustrating over time. I toggle over to LTE to troll around XDA and I toggle back to 2g only to find out I missed 2 calls. Sometimes I don't get the missed call icon right away either

Are you using the Chroma 5.1.1 ROM? If so that shreds my last idea, lol. I am so tired of being pissed off over this, I'm starting to think its funny. Then I remember the package call I missed last night and needing to use Google voice to call my mom for Mother's day today.

I heard from another user in North Seattle that is having the problem starting the exact day my problems started. Starting to look like it is happening in bunches around specific regions. I wonder if there is a specific band/frequency in Seattle and Phoenix? And I wonder if it is the bands/towers being used by Project Fi?

Great idea! I posted a thread on the official Google Nexus forums here:

Click on "Me, too!" at the bottom of my post. I also encourage everyone to report the issue to Google either through your Nexus 6 or through chat. Let's do both if possible but I feel like chat will be more helpful. The more chat reps hear of this issue the more likely it is that it will make its way to someone who can address the issue at Google.

Remember that this issue is not happening to the entire Nexus 6 userbase so it's up to us, the minority, to make ourselves heard.

Having the exact same issue since May 4th. Tmobile is clueless about it. I'm on LMY47M in Phoenix, AZ. Replaced SIM, factory reset, was about to downgrade the radio as well. Looks like nothing is resolving the issue. Will be watching this thread closely!
[Nexus 6 Q&A, Help & Troubleshooting] JohnCorleone:
Guys, something truly strange happened today. After I posted in this thread earlier today, my phone worked for 2 calls in a row for the first time since January on LTE....then stopped again. There is a problem between the handoff of LTE and whatever they call their 3g (HSDPA) for me because this device doesn't support VoLTE. Mine drops to 3G in call.

So is it all west coast so far? A T-Mo tech support guy told me months ago (early FEBRUARY) that there were known issues in the Southwest area. If its effecting newer devices, account credits are in order

I'm in Seattle, and another user posted on T-mobile support thread that they are right here in my same N. Seattle neighbourhood and started experiencing the issue on the exact morning I started seeing mine. Interesting, eh? That's why I am wondering if there are clusters of folks in certain areas that might be using a particular band/frequency. I don't have this issue nearly so much when I travel 9-10 miles south to downtown. edit: Still, I have friends and coworkers in the area on T-mobile and they aren't having problems (they also don't have Nexus 6s)
[Nexus 6 Q&A, Help & Troubleshooting] JohnCorleone:
Yeah this started in late January/early February on the M7 and M8 and HTC released an update because Google broke it with their Services Framework update. The voice features broke some HTC software for calls. There was a hot fix a developer came up with. Now since they expanded and rebranded. the app it has spread to other devices but the fact that it could cause problems on a Nexus device is troubling. It does seem to be a west coast problem though.

I contacted qbking77 and a few dev friends in the Midwest and East coast to check on their Nexus 6's. I was shocked that after several months mine briefly worked so its OBVIOUSLY with the carriers software bumping heads with Google's ever expanding intrusion into every aspect of the phone

Edit..a friend in NYC had one problem with LTE calling today on his T-Mobile S6 Edge. I hope that this isn't going to become a problem of an overcrowded network. Project Fi was delayed and someone who is testing had all kinds of drops in signal as well
