Constant network issues

I am on my 3rd device in 3 days. First one was rooted, second one was not. This current one is also not rooted as well.
Unless I am very unlucky, I am going to assume there is a definite issue with the network configuration on this device. Status says I have 3 bars of 4G coverage, however I cannot connect to the internet at all.
Network Signal Info says I am on UMTS with a -93DBM, data is connected. However nothing will load. If I put the phone into airplane mode and then turn airplane mode off the networking comes back online. Speeds are slow though, barely able to perform basic mobile web browsing and watching youtube and such isnt possible. Too slow an too long to buffer.
This doesn't only happen at my house, it happens in other areas as well but it does happen constantly at home. I a not a heavy data user on my account, 1-2GB monthly, so Tmo says they arent throttling me. They have replaced the SIM every time with the devices as well.
Suggestions? If I cannot figure this out soon I am going to cancel my service as I cannot pay for a service and phone that just doesnt work. Tmo seems stumped. They just keep replacing phones since I am within my 14 day return/exchange period.
However, 3 devices all having the same issues sure seems to either prove the phone has an issue, or m general area of Tmo service.
I live in downtown Tempe, AZ.

Your wifi works?
I have the same issue in my house... I have a weak signal and 4g drops down to 2g which is terrible.... 4g downloads are 3Mbps, but uploads are under 100kps
I changed the network mode to wcdma only which helps significantly. 4g drops, but quickly returns...
Give it a try...

I'm having the same issue here in Orlando. I've had 2 phones now (first one was just a bad unit) and both have had horrible network connectivity and reception. I take my SIM card out and put it in my 2 year old MT3G and it gets perfect reception and fast data transfers while the G2x is choking on network transfers.

Go complain here in LG forum. This is software issue.

have full bars but cant download anything. just sits at waiting for data connection.

We really need a baseband modem that works better. My bars goes to zero then to edge and then to 3g constantly. Any time it switches between the connections then the the bars goes to zero and it says there is no conection. Also noticed that 3g connection fluctuates very bad while doing a speed test.

How are you getting 3g? Unless you meant to say 4g?

T-mobile only has 3g connection avaliable where I live, of course it says 4g on the phone but in reality it is only 3g.

I wonder if there is an issue with our network in Arizona?? I live in Chandler, and work in Scottsdale. my data times out ALLL THE TIME. Both here at home, and at work. Same with my text messaging. Literally, I do exactly what you do with the "airplane" mode. That's the only way to get my data and text working again (besides restarting).
Here are the issues I posted in the LG Forum:
http://www.lgforum.com/forum/boards/carriers/t-mobile/topics/few-issues-with-g2x#26861
(first issue posted is what you are talking about)

I dont think this is a regional issue. Downtown Minneapolis here, and I cant get it to stay on wifi or Edge/4g for more than a few minutes at a time. G1 has no trouble and shows strong 3g while my sisters mt4g shows full 4g. 4g/E symbol just flickers on my g2x leaving me with no connection. I can connect to wifi fine, but even with wifi sleep set to never it still disconnects every few minutes, and has to be toggled on/off to reconnect. Until toggling it just sits flickering 4g/E with no data connection.
I've never seen my Evo drop a E/4g/wifi connection and struggle to reconnect once in the year I've had it. My g2x does it almost every time I pick it up.

Did you try going into Mobile Networks in Settings and changing the mode to WCDA Preferred or something? That'll stop the flip flopping. That's what I have it on and that's what the phone came with out of the box.Also try Auto in that menu.

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.
Sent from my Samsung Droid Charge: Stock EE4

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!

Intermittent connectivity issues

Every so often my M8 will basically become disconnected from the network. This NORMALLY appears when I'm in a low coverage zone, and it's as if my phone just doesn't want to reconnect when I get back into a higher coverage area.
For instance at my gym, I frequently get a weak signal, but it's usually 4G. Sometimes it'll drop to 3G, and then sometimes when I get back into an area of the gym that has 4G coverage my phone will say it's still on 3G. However, there's actually no connectivity at all, and I need to either reboot or toggle airplane mode to get a connection again.
Sometimes (at least 2-3 times in the last week) it happened while, at least to the best of my knowledge, I was in a 4G area (though with weak coverage) the entire time. Again I fixed it each time by toggling airplane.
Has anyone else seen an issue like this? It's frustrating as hell. And more importantly has anyone heard of a fix for this?

Yep, actually I had a thread about this a while back; I tried just about everything (other ROMs, new sim cards, factory resets, the whole shebang) and my only solution so far (if you intend on keeping your current phone) is to completely unroot my phone, along with removing all root-related applications (namely Xposed). It still happens from time to time, but a lot less frequently then when rooted and running Xposed modules. I have a new phone coming in today from Verizon, so hopefully that unit will not have any of these issues... I still am not entirely sure what causes it, though it is definitely exacerbated by Xposed. Hopefully some of this helps? If you have any further questions feel free to ask, either through PM or this here thread.

I have a new phone now, and so far I haven't experienced any data connectivity issues. This morning I did notice that my SMS were not sending properly, but that issue has since faded away, so hopefully it was Verizon network based... Anyways, I will try reinstalling Xposed and a couple modules later today (likely Snapshare and the Sense 6 Toolbox) and will report back sometime tomorrow or the next on how it goes. Fingers crossed...

Lol, so after installing Xposed, I suddenly started having issues maintaining a solid 4G connection; 3G works fine, just whenever I do manage to connect to 4G I am unable to use any data (says I am connected to the mobile network, but I do not get any upload or download data movement). Even after removing Xposed and all associated modules, I am still experiencing this problems. I am going in today/Monday to get a new SIM card (hopefully this is what is causing my issues) but goddamn I just cannot seem to catch a break in terms of my phones' data connection. If the above doesn't work I may have to send for another phone, though after having now received three replacements this entire process is getting a little irksome... I really do love this phone, but it seems as if it is my M8 is rejecting my love from every angle.
UPDATE: The new SIM didn't do anything, I still am having 4G issues, so another phone it is...

it's not just your phone....

a lot of feedback on the web across multiple carriers of the poor lte signal retention on this phone.....this is starting to sound like a hardware defect or a major "radio" software glitch.

I had the same problem with my new M8 when travelling from/to areas with low or no data coverage back to areas where I knew there was a LTE signal. Only toggling Airplane Mode would make the data reconnect. That problem was solved for me with a new sim card.
I also had very bad data connectivity at home in a major southern California city (best was -105 dBm) whereas I got up to -83 dBm in some rural town in Arizona.
Read trook's posts #34 and up here: http://forum.xda-developers.com/showthread.php?p=53838257
Some of these problems may be connected to the new data service VZW is rolling out.
I would wait a few weeks before ditiching this phone. 'Cause it rocks!!!

it has nothing to do with the AWS rollout - i have a Verizon Galaxy S5 sitting right next to my M8 ---- guess what - consistent data speeds on the s5 (15 mbs down)......on the m8 (3-4mbs down) - and the data flucutates and in the signal meter , I'm getting about -6db less on the M8 than the s5.
trust me, i so desperately want to keep this phone, b/c quite frankly, i hate the amoled screen on the s5, but alas, i cant keep a phone that doesn't work well

yes - sorry bro - i'm quite disappointed by what i am seeing with my own two eyes as well as all the others across the US and the rest of the world who are experiencing the SAME symptoms. so this is not a verizon network issue --
me thinks its a faulty radio which is causing bad handoffs between 3g and 4g (LTE). once the phone drops down to 3g, it never regains 4g signal for some reason. also, there is the issue of the constant signal fluctuations even when the phone is on LTE...so who knows. maybe combo of bad radio and poor quality antenna module.
i'm not a phone engineer but i have enough common sense and knowledge about phones to know a lemon when i see one......so, yup, i'm keeping the s5 and return the m8 tomorrow under the 14 day guarantee from verizon. shame....

To tell the truth I have been reading about the same issue on the general M8 forum - probably just didn't want to make the connection.... So thanks for opening my eyes.
I'm hoping for bad radio software that may get fixed with some future update (although my 6th sense tells me it's the bad antenna module....)
Too late for me for a clean exchange. Gonna have to read the Squaretrade fine print.....

[Q] Edge and GPRS data connections abysmally slow on Moto G

I've been testing out the data speed connections with my Moto G on Tesco Mobile. When it is showing a HSDPA connection (H+) or UMTS (H, I think) or 3g (3G) data connection speeds are what I would expect.
But as soon as it drops to Edge (E) or GPRS (G) I get speeds so slow that practically no data is being passed - even with a full 4 bars of signal.
And I am well aware that Edge and GPRS are significantly slower than 3G and its superior data connections, but I'm talking less than 0.03Mbps speeds as measured by the Speedtest app. The speed is so slow that useful "out and about" apps like google maps refuse to recognise that there is an internet connection present.
I've raised this with the network and they say that for all of the cells that I've accessed data speeds shouldn't slow that much, and suggested it might be a faulty SIM (perhaps). But today on a different sim in another Moto G on a different network I experienced the same - Edge connection was connected, but practically non-existent.
Is this anyone else is experiencing, or am I just being really unlucky in the cells I am located in?
Thanks!

I've been testing out the data speed connections with my Moto G on Tesco Mobile. When it is showing a HSDPA connection (H+) or UMTS (H, I think) or 3g (3G) data connection speeds are what I would expect.
But as soon as it drops to Edge (E) or GPRS (G) I get speeds so slow that practically no data is being passed - even with a full 4 bars of signal.

Yes, slow edge nd gprs sppeds experienced by you is possibly due to ur location....coz i get a decent edge speed as well as my friends too who r also using moto g.....So nothing is wrong in the phone it just depends uoon location....

Thanks for taking the time to reply. I don't think it is location as the problem seems to be consistent in every cell I am in. I've obtained a fresh sim from the network to see if that was the problem. Will post back with any further info!

Well....do u have any friend who is using Moto G and getting same problem at that place??And by the way, Here in india some operators give faster 3g speeds but 2g speed sucks...So just like that it could be the operator's prblm too....First confirm if any of ur friends are getting better edge or gprs speeds.....Thanx

On my old phones I was used to only use 2G (Edge or GPRS) networks in order to get one day of battery life. On my Windows Phone 7 device with an Edge connection it would sync emails, send and receive them and I could even browse (slowly) the internet.
On this one Edge is slow as ****. Furtunately H+ isnt that heavy on its battery as in order devices but when I get to places without a 3G connection the phone gets pretty much unusable, its a shame...

Interesting. For the full story:-
I have a Moto G with Virgin (MVNO in the UK using the EE network), and have had for about 5 months. Love it. Never had an issue with data speed on any of the "flavours" (obviously GPRS and Edge are slower, but useable as you say). I've just persuaded my wife to take a Moto G too, but she is on the TescoMobile network (MVNO in the UK using the O2 network). I obviously don't expect our experience with data speed to be identical, but she has only had the phone for a week or so and she reported to me last week that it seemed that data was turned off so she couldn't use maps when she was driving to get some travel time updates. When I looked at the phone at home, it was all fine - and at home both of us get H+ signals throughout most of the house (when wifi turned off). On playing a little more, I noticed that in one room of the house the signal dropped consistently to Edge, and when testing data speed there I noticed the slow (unusable) speed. I swapped the sim into my phone (which was a sim free purchase, so unlocked) and got the same issue. I've then subsequently tested data speeds when we've been out and about in different cell locations, and consistently when she is on Edge or GPRS the data drops off a cliff. HSDPA is always fine.
Then yesterday I was out and about just with my own phone in an Edge area, and I also got the same experience - unusable Edge data speeds (bear in mind this is now on my network, Virgin). Now, I've only had this once, but I am wondering if the 4.4.4 update has slowed Edge / GPRS performance, as the common factor across both my phone and my wife's is that they have only just been updated to 4.4.4
If no-one else here is experiencing the same, then clearly it is just local signal issues, but it does seem peculiar that both phones, on different networks and in different physical locations (up to 30 miles away) appear to be experiencing something similar.
Both phones are on 210.12.40.falcon_umts / 4.4.4

I've just found something to try. Won't be for everyone, but using the "hidden" phone menu via *#*#4636#*#* > phone information and setting preferred network type to "WCDMA only" I can at least force the phone to ONLY use a 3G connection. Whether that will leave me with no signal in areas where I'd like to have a signal I'll wait and see, but I could at least switch manually back to 2G if I found myself down a dark country lane with no 3G signal. Perhaps an option only for the tech-enthusiast, wouldn't want my wife to be relying on this if her car broke down in the wrong end of town!!

It may be a work around, but I can't possibly rely on that since being unreachable isn't acceptable for me.
Let me add that I experience these "issue" since I can remember, so definitely 4.4.4 wasn't the culprit...

There is an option "WCDMA preferred" which may (I know nothing about this!) set a preference for a stronger reliance on 3G services rather than 2G. It's very easy to set up and switch, worth a little experiment if you get into an area where you are suffering with a slow 2G service.

Changed it right now.
If I feel any difference I will leave the proper feedback.
Thanks

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?
