[Sprint][Android 6.X] Constant LTE Data issues, dropping off network - Nexus 5 Q&A, Help & Troubleshooting

Hey, I have been having constant data LTE issues, and I am not sure if it is a problem with hardware, or something that I just can't figure out.
Issue:
What happens is that the LTE Data just drops off, it still says I am connected, but no traffic can pass through. When this issue usually occurs, it isn't that a DNS error occurs, or it can't probe the DNS, it just seems like my traffic is being restricted from moving across the network. Along with that, I can't seem to achieve any speed (for the most part) over 2.5Mbps/4Mbps (Download/Upload) in high signal areas (both Urban and Downtown neighborhoods). This happens in multiple cities (San Francisco, Raleigh, Dallas, Greenville), on one of the sole times I got a decent speed was in San Francisco after disabling LTE Band 41. Enabling and disabling LTE seems to help this issue temporarily, but when doing so, sometimes it hangs on to the Sprint network for ten minutes or so before finally acknowledging it was dropped off.
What I have troubleshooted:
Sprint Store- had them reset SCRTN, new SIM card, and check TX/RX Power (they said everything looked fine)
Disabled LTE Band(s) - other than the exception, to no avail
Updated Profile/PRL
FDR Phone
Clean upgrade from 6.0.0 to 6.0.1
I was wondering if anyone else was having issues since the upgrade, if there was any known issue with Sprint/LTE and Marshmallow, or if anyone had any other ideas, or could offer any advice on what would be causing the constant network issues with this phone. The phone itself is out of warranty, so I can't replace it from Google or LG, if I have to get a new phone, I was thinking of getting a Nexus 5X or 6P but without actually being able to see them and hold them, I am a little concerned about purchasing one out right.

Fed up with 3G/HSPDA Issues!

I have been having some really annoying issues with the 3G capabilities of the Touch Cruise. I actually think it is something AT&T is doing on the network, but can't be sure. Anyone experience anything like this? Here are the symptoms:
1. The TC worked great on the 3G network when I first received it. Averaged around 700k speeds.
2. I flew across the state and the phone was unable to make or receive calls. I noticed the 3G/H symbol just fine, but no voice, no data. On a whim, I turned off the 3G and went back to Edge and everything worked fine, slower - but fine. I noticed this behavior on several subsequent trips. Coverage maps show 3G capability.
3. I've been to numerous other cities and experience varying 3G speeds, but the phone definitely works.
4. Lately I've noticed the phone almost seems to experience 3G "fatigue" by the end of the work day. In my home area where it seems to work fine, I'll look at my phone and it will either have no service, or it will not be working on 3G (no calls or e-mail). By later in the evening, it appears to be back to normal.
5. A reset will normally bring things back at least temporarily.
6. I have been trying out new ROM's and Radios posted here, but don't think they are the source of the issues. I've upgraded and downgraded with the same results.
Is this the AT&T network? Could it be with the proliferation of 3G devices, the network becomes saturated particularly by the end of the day?
More importantly, if 3G is for some reason unavailable the phone should degrade gracefully enough to allow it to continue to operate on the Edge network without any interaction by the end user.
Anybody else experiencing this behavior? Any tips? Any resolutions?
Re:
You could try to fix the GSM and 3g bands in the phone settings from automatic to your specific band. Normally that reduces ur battery usage and provides better network clarity. It might just help.
Secondly you could try the SEA 6.1 official rom as that seems to be one of the best ones so far.
I had plenty of 3G / Edge issues when i first received my TC. I spent many hours with AT&T tech support as well as a few conferrence calls with AT&T and HTC. No one was able to come up with a viable solution. Being a geek at heart I spent many hours testing roms and radios. Only a few combinations work with the AT&T edge network. My ROM is based on 18129.0.4.5 with a murata radio 1.58.21.23(must be certified murata) and has worked for me with no problems.
Hope this helps

4G LTE Data Connection "Stall"

So I have a perfectly good 4G LTE signal going, data speeds are great and all, but every once in a while it will just stop receiving data. The 4G LTE icon is still there, occasionally I see the upstream arrow flash, but the downstream arrow remains blank. A difference that I see from other people's connectivity issues is that I never once see it switch to 3G/1X when this happens.
One thing to note is that this behavior is not readily apparent until you're doing something real-time network dependent, like streaming audio/video for a considerable duration of time until it cuts you off suddenly.
Between 10 seconds to several minutes after data stops transmitting, it starts working again. Sometimes I get impatient and just toggle between CDMA only/LTE automatic to get 4G LTE working again without having to wait.
Is this a common issue among Charge owners? I noticed the reviewer at Anandtech had a near identical experience (though not always fixable without a reboot for him):
"My only complaint is that every once in a while, the LTE data session sometimes stalls briefly – sometimes for a a few seconds, other times for a few minutes. When that happens, you’ll see the uplink green arrow blink, but no orange downlink arrow. Rebooting the device fixes things."

After conversing a bit with him (he also reviewed the Thunderbolt/Revolution), this apparently only happens with the Charge, but he also has faith that Samsung would fix this through software (RIL) or hardware (firmware). Given Samsung's track record with smartphone updates, I'm not so sure they will.

Considering a month after the phone's launch we already have a Gingerbread leak I think this device will most definitely see support from Samsung. It is a DROID branded phone after all, and Verizon is statistically the best carrier for updates, they do take special care of the "DROID" phones over every other Android handset.
4G is flakey, on both devices that offer it. I have both the Thunderbolt and Charge with me most of the time, and I see all kinds of flakiness on both. It's the network.
It is definitely the network. I had a Thunderbolt before the Charge and it was FAR worse with network connectivity falling off the face of the planet despite having full 3g/4g.

I have had the same problem. I usually wait and it comes back in about 30-45 seconds, but it is annoying. It was really bad for a couple of days but has been better the past couple.
I personally haven't had to much issue with 4g dropping out. However people need to keep in mind that LTE is new for both the mfgs & carrier. So it is going to take time to get all these bugs worked out. That said I have to give props to VZW and the mfgs tho because back when they were building out 3G originally you want to talk about issues my lord was it bad.
I have had this issue, with the 3G and the 4G, but I can't say that it's a deal breaker for me, compared to the lousy HSPA+ signal my Vibrant had. It's only ever happened to me at my house, which is right on the edge of LTE coverage, so it switches back and forth a lot. But I have to give the network the benefit of the doubt for right now, it's a brand new network and a brand new device. And the 97% of the time that things work properly, it's so far above and beyond the T-Mobile network I have no regrets about switching.
I called Verizon with the same issue last Friday. Their resolution after a couple of questions was to overnight me a new (certified like-new) Charge and SIM card - the replacement was received on Monday. I haven't had any issues since, but I also stopped seeing the issue after I made the complaint.
Regardless, replacement has been better and locks a GPS signal much quicker. Maybe it's the SIM card?
SAME CRAP HERE!!!!

I tested if I have this behavior using LTE only mode (dial **583 in Phone app) and indeed I do, so this furthers my belief that my issue is not due to something wrong in the hand-off between 4G/3G.
I found out the way to actually change the data modes and tested using EV-DO Rev. A instead of eHRPD (in conjunction with LTE) and also using just CDMA 1X (in conjunction with LTE, essentially disabling 3G), but my issue of dropping data exists. The 4G LTE icon is displayed the entire time when it happens, I just seem to lose connectivity (and all three of the tests in the Phone Info area fail) temporarily. For what it's worth, I'm not moving the phone around at all when this happens.
I think I would actually be more content if when the data connection stalled, my 4G LTE icon just disappeared or if it switched to 3G because then it would make more sense to me (that I may have lost connection to the 4G service and it's attempting to reconnect to either 3G or 4G), but as it stands, all I get is a constant 4G icon with intermittent dropouts. The switch to 3G/1X seems to be the more common issue among 4G smartphone owners, but my (and the reviewer at Anandtech's) issue seems to deal completely within the 4G network, and I've tried every leaked radio to no avail.
The regularity of the dropouts seems kind of random as well; I'm not sure how I can figure out the source of the issue. Does anyone know if there are some logs that I can look into to see if something is happening to my phone at the very instant that I'm having these stalls?
Of course, I'm not discounting the fact that it might completely be on the side of Verizon's network and/or my area in San Diego and has nothing to do with my phone, and I may in a minority of users that actually continuously uses the 4G enough to notice these dropouts, which on average happen once every half hour to hour or so. Sometimes I'm able to stream something for several hours without the stalls, and other times it'll happen frequently within a short time span.
I just got off the phone with tech support for the intermittent data drop problem. After confirming that I was on EE4, and that I had tried doing a factory reset, he is fedexing me a new sim card.
Really hope it works, I love the phone but losing data for 1-2 minutes at a time randomly is pretty lame. Especially since I switched to Verizon for their reputation as the better network.

Is your problem the same as mine (data drops all while 4G icon is displayed) or is yours the more common 4G to 3G/1X transition or losing the 4G network icon data drop?

The data will stop. Then the 4g or 3g icon will disappear entirely for a minute. Then it will reconnect at either 4g,3g or 1x, I don't really see a clear pattern, it seems totally random to me.
Is there anyone who's reading this that regularly uses their 4G continuously (i.e. hours) for streaming web content (e.g. radio streams, live video streams, etc.)? If so, do you experience any occasional dropouts or is the 4G connection for you rock solid?

Tested on mine and same result.
Edit: Rebooted and it works fine been on it 20+ now, I'll be testing some more
A couple of days ago my SIM card crapped out.
Now that i have a new one my 4G signal has been more consistent and stronger than ever. I live in a fringe area and before the new SIM it would constantly switch between 4 and 3G. Now i go for hours on 4G and it even stays on 4G in places that it would always switch and stay on 3G.
Get a new SIM before getting a new phone.

After reading this thread I'm considering switching to either the Thunderbolt or the Revolution, or something else when it comes out...
Anyway, I have experienced this same thing.
The only difference in my situation is that I'm trying to use my LTE internet as a dedicated connection. The setup I'm trying to do is plug my phone into my router and have the router distribute the verizon LTE internet through my apartment. My router currently has the latest version of tomato installed and I compiled my own RNDIS module (modified to work with the charge). Everything works for the first few minutes (15-20), then I notice the 4G icon "stall", then disappear, then reconnect. After the first disconnect and reconnect, the internet connection is very unstable and will disconnect every couple of minutes until I disable and re-enable the internet again... very frustrating.
In the interim, I've been using EasyTether and this works very well. I have streamed hours of 720P video and it works flawless; not one skip or reconnect.
This leads me to believe that it is either one of the following:
The kernel - I'm currently using the PBJT kernel found in the latest version of humble. I'm not sure if the stock rom will provide better stability.
The radio - I currently have the EE4 radio installed, but am very curious to know the stability of the GB radio updates (EP1f, etc.).
Any other ideas would be greatly appreciated!
Thanks!

Data Connection Issues

Have anyone experienced data connection issues on the AT&T variant, some of my apps like Craigslist won't open, but it will on other devices?

Yes. I am having issues on my Sprint Note EDGE. The signal goes up and down and the data is very spotty only giving me any data about 20% of the time. I am waiting on my replacement but I doubt the phone is faulty.

My issue is now turning out to be one app, which is Craigslist. I can't connect via AT&T data, but I was able to use a Verizon Hotspot to connect.
I have noticed data & wifi connection dropping frequently. I have been blaming my mobile operator and internet service provider until I saw this thread.
On my T-mobile Edge i was getting Wifi drop outs every minute or so.
I am getting a replacement tomorrow and I will report back.
here is what my battery stats looked like

Firmware.....
Its a Firmware issue
Guys I am almost positive this issue is due to a glitch in Samsungs firmware. I tested the data and was able to download over 1 megabyte per second with only one bar on 4g Spark LTE.
According to the tech support person I talked to that would not be possible on only 1 bar. (btw I stopped the test after hitting 1 Megabyte per second for those that need help converting that equals 8mbps). I was in a saturated 4g Spark network with 5 towers within spitting distance from my location and it still only showed 1 bar. I'm thinking either how the tower reads the signal strength or a bad code line shows no more then 1 bar no matter what.
Now for those having dropped data. Check the Sprint {if you are on Sprint or your providers site for a similar coverage map) site to see the saturation for 4g Spark service, the phones are now setup to LOCK on and HOLD onto the FASTEST tower, which according to the tech who also filled me in on the way the new antennas work, can lead to what seems to be dropped service. She would recommend for individuals having this issue if Spark service is not fully activated in your area to switch over to CDMA only under settings to fix the LTE data dropping issue. BTW the Spark LTE service is apparently different then the old LTE service so those versions do not appear to work interchangeably (according to the Sprint service map). I'm assuming this new triband lte is new for all the carriers but maybe not...
I also noticed someone else got the new version of the firmware, which I also have and that did NOT fix anything for me. If anyone is struggling with this issue I would wait until the firmware is updated again. WHICH I hope by that point we can get flashable firmware for those of us that are rooted...???
Now for a VERY Important Fact: there will now be no way to use data while on a phone call. These phones are a single antenna model. You can either be on the phone or data... UNLESS you are making a WiFi call. That is why this is now a option. It will keep the antenna set to the data side of things and make it possible to use data for the internet at the same time.
I hope this helps.

Thank you for the info. I agree it has to be a firmware issue. I am getting a replacement handset tomorrow to verify that but I can see all these hansets being bad. I am in areas all day long with strong lte/spark/and 3g but my data connection constantly drops. I do also see the cellular signal shooting up and down but have no issues with my call quality at least. Have to reboot...toggle airplane mode....or shut data off and on just to get a little bit of 3g service for a second or two. I really hope the firmware update comes soon. I also went under networks in setting and set it to CDMA only and it as at least seeming to give me a steady 3g connection for now...will reply if that changes
signal
I had the note 4 for 3 weeks before giving it to my wife and getting the edge....the note 4 in all my normal travel was perfect....now with the edge i have horrible data so its something i hope they update quickly
I don't rely on the stock signal bars, they are not really reliable in my opinion. Instead if you install SignalCheck Lte or SignalCheck Pro (for those that are rooted) from the play store. It accurately shows the true signal strength of your connection.
I like the Pro version since it allows to reset the connection quickly if need be.

SMJ700h stopped working, how much of the Samsung official line is true?

this is the phone from the https://forum.xda-developers.com/galaxy-j7/help/4g-lte-sm-j700h-t3543821 thread. I had become used to this phone not being 4gLTE supported.
But over the last month, almost all data usage has become so excruciatingly slow that data has in effect stopped. Most pages seem to stop at about the 15% mark. Waze wont pick up any signal at all and even CoPilot gives arcane errors when it is accessing data as opposed to GPS.
Samsung sent me to their 837 Washington repair location where on an absolutely minimal 'inspection' the bloke there identified that I have an international phone which he announced will not work and cannot "for hardware reasons" be made to work in the US. He said it has the wrong radio to work in the US. (dont I remember updating the radio as a software feature on my Cingular 8525 reasonably regularly? This is j700hxxu3bqc2)
I wondered whether this hardware impossibility could be the case if it had been working for 9-10 months, if a bit slowly. I said the problem had only started over the last month. He said T-Mobile had been changing things within all their transmission towers about a month ago. After which my SIM1 is now admittedly in constant "Roaming" mode on the home screen, although SIM card status shows tmobile in service, EDGE, not roaming (and mobile network disconnected with a signal strength of -87db, 13asu whatever that contradictory info means???).
Can I do anything about any of this please? Could I achieve anything by rooting and flashing?
None of this has anything to do with Smart Manager being in what it calls ultra data saving mode does it?

Wildly intermittent data connection

Starting about two weeks ago my phone started dropping 4G signal down to 3g with no apparent reason. This is in the same locations that I've been in multiple times in the past and had excellent connectivity. To make it more interesting, my wife has the exact same phone purchased on the exact same date. standing next to her she will be on 4g and I will be on 3G. This is on the Verizon service. So far I have been to Verizon and replace the SIM card. Reset data connection. And done a factory reset. If I cycle the airplane mode four five times in a row many times but not always it will restore 4G service. Any guesses at all?
Open 'About Phone' under settings on both phones and compare various versions. One may have received a new update before the other.
Ever since the March retail update my signal indicator seems to constantly bounce from Edge to H, H+ and LTE(xt1955-5 on TMO). When I am in an area with good reception(I live deep in the sticks), the download rate(1-4 MB/s) does not waiver despite the signal indicator changing every 10 seconds. When reception is known to be sketchy, and it indicates I have LTE, I am still lucky to get 100 KB/s max down.
Is your phone rooted? If so, what ROM are you using?
Some ROMs (and perhaps stock firmware) have an option to choose the preferred network type for your phone to connect to. Perhaps the setting was changed to 3G on your phone.
Replaced
Never did get to find out what the problem was. I was able to get a warranty replacement. Thanks for all the suggestions. I did look into most of them. I think it helped me get the warranty service expedited by saying that I tried all these various things. My wife's phone in mine are on different software versions. However my replacement phone, which I'm presently using, had the same software version that I had problems with before and it's working flawlessly. So it ended well but I still have no idea what happened. Thanks again for all the help and suggestions.
