In my home area the 4G reception is very good. Good coverage with no 'black spots'. My private phone (Samsung S8) has 4G connection ALWAYS.
But with my work phone (this Nokia, dual SIM version on latest security patch of Android 9) on some occasions, the phone just loses 4G reception and falls back to Edge ('E'). And than it will stay there for at least 10 minutes, before getting a 4G fix again. Switching plane-mode on and off doesn't fix it and a complete reboot only sometimes seems to bring 4G back.
Does anyone know what can cause this behaviour and how I can (try to) fix it? It's driving me crazy!
Cheers

I've noticed this over the past month and thought I'd share and see if anyone has been having the same experience with 4G data.
I'm in Miami Lakes, which is a suburb of Miami, and while Miami officially has 4G now, my suburb isn't listed in Sprint's coverage map as being covered by 4G yet. However, I've been getting a 4G signal at home for over a month now.
I have noticed, though, that I can't download/received MMS messages while on 4G but as soon as I switch to 3G, they download just fine.
Another thing I noticed is, it takes a second or two for 4G data to actually wake up. What I mean is, when my phone locks (screen turns off) and I turn it back on and go into an app that needs a data connection (i.e. Facebook), about 50% of the time I'll get a message from the app saying that there is no data connection (eve though the 4G icon shows I am connected to 4G) but if I back out, give it a second, and go back in, all of the sudden everything is fine. Just like my MMS issue, that doesn't happen with 3G either.
I think it's safe to assume that these issues are due to the fact that 4G isn't officially implemented in my area yet and they are still configuring and installing these towers I'm getting signal from.
I thought it'd be interesting to see if anyone else is having these issues in their "unofficially" 4G-covered areas or even if some people with 4G officially have experienced these issues.
I should also note, I've experienced these issues with both my EVO and my Epic.
Hey everyone!
I was wondering if anyone else is having the problem where if you toggled your 4g to turn it off, you would lose all data entirely? I currently running winner's kang-cm9 and when I try to turn off 4g through the toggle or through the settings, I only get gray signal bars. I'm assuming I should still have 3g after turning off 4g. Is this someone that everyone is experience or is it my phone?
I'm having a similar issue (stock ROM). I notice it every morning when I leave for work. I leave my place and wifi disconnects (lack of signal). Since I don't have LTE outside, it seems like it try's over and over to obtain LTE signal. LTE is spotty in my area, so it will go in and out. However, 3G sometimes fails to connect and I sit there without any signal. It's incredibly frustrating...
Last night I just flashed to Apex ROM/Kernel. This morning I waited for my car to warm up a little bit and by the time i plugged in my phone, it had a 3g connection. I will be continuing to look out for this, but I have been able to replicate the issue in my first paragraph over and over again... something is definitely wrong with the radio on our phone (CDMA).
Oh that happens to me a lot too because I get bad 4g in my area so a lot of times when its switching back and forth I lose data for a while.
The problem I'm having is that I would try to disable LTE/4g to save battery but would end up losing all data (Only calls and text work). On my friends thunderbolt he was able to disable 4g and retain his 3g data. As for me, I lose all data and I have to restart to regain data again when I try to disable 4g data

That's an interesting point. I was wondering how the other LTE VZ phones handled this situation... I think VZ/Google needs to address this in a fix ASAP.
I work in a largish company in Seattle area. We have ~5000 engineers working in the area and I posted the same question since my Verizon GNexus would completely lose all mobile data for hours at a time every 3-4 days. From what the results I got, they said that in our area they are all seeing those problems and they had different devices. I got responses from OG Droid, Droid Charge, GNexus, DroidX2, Thunderbolt.
I've been seriously considering returning my phone since this is clearly a verizon data network issue which is not limited to LTE as their press releases would have you believe.

Well see, i can get data if i toggle airplane mode or cdma to cdma/LTE. it takes me forcing the phone to start looking for 3g instead of LTE.
Very serious issue. Slow reconnects on a toggle that should be unobtrusive between 4g-3g. I suffer from the same issue.
What's worse. The reception in general is terrible. And dropping from 4g to 3g ..the phone either never reestablishes 4g or take.....a. VERY long time. Like, 10-15 minutes. Unbelievable
I'm trying desperately to get google to be aware of this and I'm PRAYYYIINNGG this is a software issue.
P.s this is my third nexus... so I believe this is everyone

Yep... I have two other friends with this issue as well. I just got off the phone with Verizon, and they acknowledged the data connectivity issues... they said an update is in the works and is tentatively sometime Jan/February.... for the record, i'm on 4.0.3 (axi0m rom); not that it should matter ...
What I'm seeing is similar but sounds like it might be slightly different. I have a thread on it here:
http://forum.xda-developers.com/showthread.php?p=21352288
I'm not sure if what I'm describing there is "normal" and the thing they are working on an update to address or if I have a bad radio/phone. Any thoughts?
In my case, it will go: 4G->no_data->4G in the span of about 30 seconds or so. The 4G indicator will still show for a few seconds but I'll get "no connection" kind of messages. Then I get just a solid gray triangle. About 30 seconds later, I see the bars, then the 4G indicator, then the bars turn blue.
Anyone else seeing this? This happened to the phone before this which I swapped due to this problem. What are the chances I got 2 bad ones in a row? Or is it just a similar issue to what you all are describing?
Hello,
I have a Verizon edition of the Galaxy Nexus, and both my initial phone and my warranty replacement have had the same issue: specifically, they both will occasionally drop all data, be it 3G, 4G, or EDGE. Occasionally they will even drop voice signal altogether. (I've also had the second phone reboot randomly - not often, but it did when I tried to use Wifi Tether, for instance).
This does not happen everywhere, but since my job takes me all over town it happens a reasonable amount, (and notably, not with the Sprint EVO 4G work phone I have). I am based in Sacramento, CA.
My phone is rooted. I have heard that the phone may have issues with switching towers? It is able to reclaim a signal reasonably quickly once it drops, (10-15 seconds) although sometimes I have to do nonsense like switch in and out of airplane mode to force it to grab a 4G signal.
I'm coming up on my return and refund period within a day or so and would like to know if I should dump this phone for an HTC Rezound, or if this is something I can fix by installing the 4.0.3 leaked software.
Thanks in advance for your help.
I know that there is a newer base band you could try flashing, and 4.03 might also fix some of your issues, but be aware that you are pretty much beta testing new technology.
I've never had voice drop on my GNex, but I will occasionally have a drop of data. I believe in my case it is because I am on the cusp of 4g coverage at home, so sometimes it will (barely) connect to the 4g tower, and then disconnect and go back on 3g. When I'm at work and I have solid 4g coverage this issue doesn't present itself.
To remedy the situation temporarily I just switch to CDMA when I'm at home, and if I am in an area where there is 4g and I want faster connection speed I'll re-enable LTE. I know this sounds like a ridiculous solution, but I love my GN too much to return it...again, we are early adopters of new technology.
Only 0.6% of android users are even on ICS - all of this technology is very new.
I believe as Verizon rolls out 4g to more areas that currently only have 3g coverage we will see less and less drops in data (greyed out bars). Hopefully Google/Verizon/Samsung will improve on the radios, etc and make things more smooth for us.
As far as wifi tether goes, I know they JUST got it working on Galaxy Nexus recently, and it is still in beta phase, so I wouldn't count on it being bug free...I had a reboot once when using the beta 10 version, so I don't think what you are experiencing is all that uncommon.
I had a similar issue but only when I was in 4G coverage. I would randomly completely lose signal for about 30 seconds and then it would come back. Usually happened quite often..about 4-5 times an hour. I ended up taking it back for a new one and a new SIM card and haven't had that issue since.

I bought a new GNex last week and immediately ran into bad connectivity issues when preferred network mode is set to LTE/CDMA. Basically no signal all (3G or 4G), even though I live in downtown Boston where there should be 4G. When I switch my preferred network mode from LTE/CDMA to CDMA, the 3G network works fine with no connectivity issues.
On the phone, Verizon told me that a software patch in May will fix the issue. A staffer at the Verizon store told me that I could already find the patch online and that it would solve the problem... I assumed he was talking about 4.0.4. I flashed 4.0.4 yesterday fully expecting it to solve my LTE connectivity problems but ..... no luck. I still get no signal using the LTE/CDMA setting. I can't even make or receive calls unless I switch back to CDMA.
Do I have a hardware issue? Are other people having the same problem? Should I trust Verizon and hope that the 4.0.5 OTA update fixes the problem? Is there anything I can do about it now?
I am in the same boat as you. Just got a replacement from Verizon but it had a horrible purple tint to the screen so its going back. Didn't even get to see if its better at 4g. I think its a hardware problem as I've read that some people were able to get a replacement phone that actually works.

My problem is similar. I can get 4G and use it sometimes but after a short time of data usage all my data is cut off until I reboot the phone. No calls, no nothing. I logged a ticket last night and will be calling back today for an exchange.
edit:
I stopped into the VZW store after calling customer care and getting everything all setup. They swapped out my gnex for a new one and so far my experience has been positive. I'm seeing improved signal everywhere and last night the phone didn't drop connectivity once or even get warm. The old phone would get hot to the touch in the upper left of the screen, the new one stayed cool throughout 30 app downloads with 2 bars 4g. Here's to hoping my problem is solved.
I'm getting a similar issue with connectivity dropping ice had this phone for three weeks and the signal drops terribly. At my house because I live on a mountain by a Penn state campus I know there isn't much in the way of signal because of the distance from the towers without interference. But even with being in other areas with 4g I still run into the signal dropping...I thought it was just me so it's good too know I'm not the only one having issues

My Galaxy Note 5 SM-N920I purchased December of 2015 can no longer make or receieve calls. My provider is TracFone via the Bring Your Own Phone program. I use their SIM card and it has worked all this time. Until recently the phones features have stopped working. I think they have been disabling the 3G in my area, as everyone is converting to 4G now.
Note 5 is supposed to support 4G but it's definitely been having issues. Text and internet still works. however texts are sometimes delayed on occasion, not always, usually it's fine. Data speed just now was tested at 10 mbps down, 3 mbps up. Signal bars are consistently low, regardless of physical location; inside, outside, other side of town, SIM status shows signal always between -108dBm and -118dBm. This is likely why I cannot make or receive calls, but the question is, why is this happening?
Like I said, I suspect they are shutting down 3G in this area, so the best theory I've been able to come up with is this: perhaps 4G has always sucked on this phone but I never noticed because it would fall back to the good 3G connection. Now that 3G is gone in this area, all I have to use is 4G which is a shoddy connection.
Further research has found in the early days of this phone there were numerous reports of weak/no signal. See these threads:
Fed Up With Terrible Reception
Hey all, I'm kind of venting here and at the same time hoping for some sort of direction because I'm absolutely fed up with my S6. I upgraded roughly a month and a half ago from an S4. My phone usage was below normal for the first week or two as I was busy with a variety of projects. As my...

No signal/network on my note 5
Hi everyone, so I just got this note 5 N920P last two weeks but I noticed its OS was lollipop...waited for updates for 7.0 but nothing so I went ahead and downloaded Odin with latest firmware from samobile and did it my self, now here the problems start to show first of all this hands free...
forums.androidcentral.com
One theory was that the 4G antenna they used in the Note 5 / S6 was of poor design. Causing weak signal.
Things I have tried and did not work:
-Contacted TracFone. They confirmed the device is supported and provisioned correctly. They recommended a new SIM card.
-Replaced the SIM card with a brand new one
-Factory reset the device. It's running the stock Android 7.0 Nougat which was the last up to date version available.
-Tinkered with various service menus including *#2263# and *#0011#. Messing about with the LTE band settings didn't change the signal strength ever. Regardless of the LTE band, it stays in that -108 to -118 range, too weak for calling.
What can be done to fix this? Possible ideas:
-Internal antenna replacement, but this seems either expensive to have someone do, or extremely difficult to do oneself. Would it even make a difference? Has anyone tried this?
-Software. Could the issue have been introduced during one of the software updates? Planned obsolescence perhaps? Could we revert to an earlier firmware to potentially resolve this? has anyone tried this?
-Firmware. Could we upgrade the firmware to a later, unsupported version safely? Perhaps the issue was fixd in later Android versions but has not been adressed in older devices that are no longer updated.
I'm the kind of person who likes to use my things until they absolutely die. This Note 5 has been perfectly fine until recently. There is nothing wrong with it. It's still modern, fast, and has a great camera. I would HATE to have to replace a phone for such a stupid reason. Not only is money tight, but it's such a waste when this thing is still perfect apart from this weak 4G signal.
Has anyone else had this issue? Have you resolved it? Any help appreciated. Thank you.
Try a network reset.
Clear sim toolkit data.
Clear system cache.
The access point profile may need updating or maybe the sim?
