Nexus 6 connectivity/LTE issues - Nexus 6 Q&A, Help & Troubleshooting

With Verizon I started to have drops in signal all together and rarely could connect to 4g. I went and activated a sprint account and it first things seemed fixed. Now 24 hours later my phone will not connect to 4g even though signal monitors show a LTE connection, I have to force a 3g connection to have internet. This is happening in areas with great 4g coverage for both providers. Would you consider this a defective phone? Has anyone else experienced these issues? Any help would be great both Verizon and sprint seem to be at a lost about what's causing this.

[Q] 4g data problems at home

It seems I have very good 4g signal at my work but when I am at home, it gets stuck on either 1x or 3g, according to sprint, there is 4g coverage on my house.Does anyone have problems with 4g not working properly? Its getting me annoyed since I use hotspot at my house. Any suggestions would be helpful.
I've noticed it'll show 3 bars of 4g at home, but if I actually start browsing it drops to 3g. My friend had done nothing but complain about sprints network so I am just assuming it's their problem.

I'm having the same problem! My friends iPhone gets better reception, and we both have Sprint. He gets LTE at my house in my office, but I get 3G or 1X. It's very frustrating. I may return the phone, or leave Sprint altogether, as I didn't have these problems with my Verizon Note 2.

I have used sprint chat with an agent and followed every troubleshooting method and still 3g. I will check the store to see if I can exchange it for another phone or see whqt happens
Could just be a week signal. Note that the signal bars on your phone are NOT for 4G. Check out this helpful write up over at S4GRU could help you determine what is up once you check LTE signal levels.

[Q] AT&T 3G signal fluctuates

Just curious on other peoples opinion/theory.
So while using my HTC One on AT&T the 3G signal jumps around. I assume its two towers one obviously being farther away and the phone doesn't seem to stick with the one that's closer. So if i force the phone to connect to WCDMA (3G/HSPA) no celluar service works on the device. Eventually I switch it back to 2G and then it starts receiving calls/sms etc. I have been to locations in the area where there are full bars of 3G constantly yet the phone fails to connect properly eventually I give up and switch to 2G at some points the phone drops down to GPRS.
On an international HTC 8X it maintains a strong connection to 3G/H+ using the same simcard. Only thing that has changed is the actual device. I've tried literally all the radios available for the HTC one and all have the same result.
If using a T-Mobile simcard and I go into an area that has been refarmed I pick their 3G/H+ just fine.
So it's not the simcard and its not the phone. I've called AT&T and all they do is make me turn off the phone while they resend the signal from the tower (so they say) then thats when the phones sticks to 3G and functions correctly but eventually it stops working and returns to how it was.
Right now AT&T offers the stronger call/sms coverage while T-Mobile doesn't so I'd rather stick with AT&T even if they suck.
So my question is.
Anyone else experiencing or has had this issue before on the HTC one or another device? If those who have had this was it resolved?
Was it a simple device exchange or were you bumped up the change of tech support eventually reaching some one who knew how to fix the issue or atlease gave more then "Please turn the device on/off, it will fix all your problems"

[Q] Quick to roam, reluctant to stop roaming

I have a Moto X on Sprint, with the latest OTA. Compared to other phone models on Sprint, my X has been very quick to roam when the Sprint 3G signal fades... This is good, and I like it. However, it takes a while to switch back, sometimes taking a few minutes in a -85ish Sprint 3G area before it stops roaming. I presume this behavior is for battery life reasons, to prevent it from hopping towers every 5 seconds in a fringe area.
Has anyone else experienced this? I also think I'm seeing a tendency to stay on 3G when LTE is present, but that may just be intermittent LTE availability as they test NV?

HTC One M8 reception worse than M7

I just got my new M8 today. Did the update, activated it, did the profile & PRL update, etc.
I am constantly getting the message that I am roaming on data. It seems to go back and forth between roaming and not roaming. Even outside I only get 1 bar of LTE and the LTE signal is a good 10dBvm worse than my old M7. My M7 never switched to roaming in the same location.
Anyone else noticing worse reception on this phone than the old HTC One?
I'm having the same issue.

I was worried bout the same myself. In the office with the M7, I wan't able to get LTE, but luckily with the M8 I am able too. I would have your phone checked at a corporate Sprint Store to see if it's faulty

I had the same issue yesterday when I upgraded my radios to the new version (1.54). I was stuck in 3G roaming at my house which was normally low end LTE service before the upgrade. After flashing the radios I did a Profile and PRL update using WIFI, then restated my M8. After the restart I am back to having LTE coverage floating around -90-95 dBvm. I also notice that if LTE fails to connect swithing airplane mode On/Off helps as well as dialing *18 from the dialer. Hope it helps.

I already did the profile/prl updates, and my phone isn't stuck on 3G. It will go 3G roaming, then 3G on sprint, then LTE. Seems to not be able to make up its mind. On my old phone it would usually toggle between LTE and 3G in this area, but NEVER did it go roaming. Even when I'm on WIFI I still get the annoying roaming notification in the notification bar every 5 minutes.
I also noticed my WiFi download speed on wireless AC is significantly worse than my M7. I used to be able to get 70mpbs on a speed test, this phone won't even break 12mbps. When I first turned the phone on it would only work on WiFi for the first 3 seconds after connecting and then it would stop. I had to keep connecting and disconnecting to WiFi to limp the software update download along. After it updated it at least stays connected and working on WiFi, but a lot slower than my old M7.
This phone was purchased on a SWAC account so I'm not sure if a Sprint store (which is 40 minutes away for the nearest one) would swap it for me.
Moved to Q&A...all questions should be posted in Q&A.

CDMA-Less Device on Verizon (Amazing!)

One of the great things about this device on Verizon's network is instant LTE service. In my house I have dead areas which cause my signal to drop. When trying to get LTE back it can sometimes take 30 seconds or more because once I get to an area with service it will first go to 3G and then sometimes get stuck on it and I'll have to toggle airplane mode to get LTE back in a timely manner. With the OnePlus6T as soon as I have service it goes instantly to LTE! This is the first time I've ever had a device connect to LTE so fast. All my previous devices over the past 5 years since I've had LTE in my area have annoyed me because they always go to 3G first even though I have strong LTE service where I live.
I've always wondered why companies can't make their phones instantly connect to LTE when it's there and why they always favor 3G -- but this is no longer an issue since the OP6T doesn't have 3G on Verizon

What now happens in the areas where you only had 3G on your old phone? On your new Oneplus 6T do you just have no signal at all since it is only a LTE phone?

Well, I'm assuming that in none LTE areas I'll have no signal at all. But, Verizon's whole network has been converted to LTE as far as I know. I never go anyone where I don't have LTE (and I live in the sticks). But in the off chance that happens I have 2 lines and my Pixel 2XL is still in service.

I too am on Verizon, and in my office at work, one of the places I had zero service on Axon 7, I still get calls and text and one spotty bar of LTE. At my house, in the basement bedroom where I have missed countless calls and txts, I have 3 bars of signal and no issues with calls, txts, or LTE.
I drive all around my county for work, and so far, I havent hit a no service area. on the Axon 7, they were evident. It could just be better coverage due to glass back vs metal (the real reason OEMs have switched to glass back imho) or the better modem of the SD 845, but hands down, the cdma-less VZW is far superior for me IRL usage so far.
This is obviously subjective, but despite living in a rural area, I have no need for cdma so far. Vzw is the only carrier with good coverage where i live (upstate SC) and somehow, cdma-less is better.

LTE only in *#*#4636#*#*
2g/3g/4g in Preferred Network Type
Yeah I was in a spot Friday that goes to 3g or no signal often. I still had some sort of signal. It had an R and an H on the signal bar I believe. It worked fine and was still pretty fast online. Signal is way better than any of the Pixels was.
When I select LTE only I get two signal icons in the status bar.
Just curious will wifi calling / VOLTE work on Verizon?

Volte has worked for me since the moment the tech I chatted with switched my sim to CDMA-less. Case and point, I am in the section of my house with the worst reception, a spot where the Axon 7 I came from got zero service on tmob and Verizon. Yet, much to my heart's content, I have service and VOLTE in the downstairs Faraday cage that is my house.
To the second part, no, Verizon doesn't support wifi calling on this device yet. Hopefully, they will work that out soon, but so far, I am having the best network experience I have had yet with Verizon.

Wow, just reset mine and noticed. I guess I had defaulted back to LTE/CDMA/UMTS, which apparently works fine. When I switched to LTE only, you are correct, double LTE icons in the status bar. I don't remember it doing that on 9.0.4. That being said, the other, default setting works perfectly fine for me.
Did y'all not have any problems sending/receiving MMS (not SMS) when your phone was in LTE only mode? I had to manually switch back to the default preferred network type from the dialer menu in order to fix that issue.
I had no problems at all I did the following.
1.Ordered new SIM card
2.Turned off old phone and took out SIM from old phone
3.Went on my Verizon account put in info on BYOD
4. Insert New SIM in 6T
Finish Setting up in your Verizon account then turn on the 6T
Done all working
I was worried because my old phone was 3G but the LTE is everywhere I always have signal.
