Sprint Instability

Had an entire section of town go down yesterday. Showed full signal but everytime anyone attempted to make a call it showed "network failure". Even attempting to call sprint's customer service numbers.
Finally got ahold of sprint via a land line and they claimed the towers show no problems and the network wasn't congested...
It is really bad since I rely on my phone for emergency response. Anyone else notice instability like this lately?

Are you in an area where LTE is being deployed? Sometimes that happens. You dont get LTE and the 3G gets worse.

Well we were on the "list" (Tallahassee, FL) but haven't seen much LTE (or any) in Tallahassee... It wasn't just 3g, the entire 1xRTT network dropped (no phone calls, no texts). I am on business so I get to use business tech (instead of consumer tech) and they viewed all the work orders for the towers in teh area. Said there was nothing currently happening that would have caused the entire network to go down and that we aren't even close to 800 SMR deployment (which pisses me off because Sprint coverage inside my office is horrible, while verizon I can get a strong 1x, 3g and LTE (my work phone and air card are all verizon)).

Same thing happened to me a while back, nothing worked, but I was roaming. It lasted for a few days, then when it started working again, I got LTE.

Same thing going on around Philly suburbs. Calls dropping like crazy and horribly slow 3g. When lte is turned on for good, does 3g go back to normal, or stay slower than the 1x speeds I get in some places?

Lolololol
So do we go ask the vendor to fix their towers?
It's Sprint's responsibility to make sure it deals with good vendors and that they maintain the towers well.

How so when Sprint's internal diagnostic tools show the tower is functioning properly (in respect to the Sprint network)?

Its possible that your area is getting 1900 network vision upgrades, which knock you out for about a week.you don't really notice the lte install because you don't have the service, but you are dependent on 1900 for voice so its not pretty. Our area just got the upgrade and we had a lot of unhappy customers, I couldnt call or text for about 6 days. I'm off for a few weeks or I would check it out for you.

So if I am scheduled to get LTE in my area soon, what kind of behavior would the network show?
I get crappy 3G almost everywhere, where every time I try to do anything, the 3G indicator goes dark and I get a network error. Whenever I get an LTE signal, it's usually a namesake, and I get knocked down to 3G. In select spots at select times, I get super duper slow 3G: around 90kbps. Sometimes 200. VERY few times, I get around 2 megs on LTE. That only lasts a little while.
I'm scheduled to get LTE this month. When should I expect decent coverage? All the threads in the International forum about gigs of data have me PUMPED!

Towers go down. Power goes out, internet goes down.
These things happen. You call Sprint, you let them know. Even if they tell you everything looks good on their end, if they get 5 calls about the same tower, they'll send out an engineer.
Expecting 100% uptime is absurd.

Normally you will just start to see 4g more often. You may some some minor odd behavior because they are up on the tower fooling around but it won't be a big outage. They do one site at a time, and once it's on it has to be tuned for optimal performance which takes a while too.
Sadly your 3g speeds are normal anymore, smart phones now days have completely overwhelmed the marginal capacity that evodo offers. Only thing they can do is to throw more RF carriers up but that can cause interface issues between cell sites and it can actually hinder performance. Areas that have complete lte toll outs do end up with much better 3g since the data hogs are now on lte, I can get about 1.5 down on 3g here where we have both lte and 1900mghz 3g network vision complete.

Same issues in Washington, DC for the Past 3 days. I sure hope its because they are upgrading the towers

Same thing happened in Houston a couple of days ago. One of the three towers in the area I work has been Network Vision upgraded, other two still in the works. Anywho, all of a sudden, no calls/texts for a span of about 20-30 minutes (longer/more in other areas). Sprint: "no issues reported in your area", I was: "yeah, I'm reporting one/some". Everything back to normal, for the time being, super-slow 3G (less than 100kbps). Thank goodness for Xfinity at home/work. I work for a preferred retailer and all we have been advised is that the upgrades are coming and will resolve and greatly improve our (Sprint's) network. Hopefully, the influx of money from the new owners will make it so. Nextel bandwidth/spectrum to be used for LTE, yes you'll need a new phone with correct radio.

I havent read much of what's going on here just skimmed through but I would like to add what I've heard.
Lately we've been having a lot of iPhones come in with data issues. Not just the 5 but 4 and 4s as well. This week alone I've seen 6 myself. Before that... Maybe 1 or 2 everyone 6 months. It's rare. And today these people plus more have come back with a worse issue. They aren't getting reception anywhere. (I'm in Washington btw). So I called my nss support team and they said as of the 17th of July sprint has been getting way more aggressive with the network vision and the iPhone's are more sensitive to this update but other device will start experience these problems and it's going to get worse all over the state till about October. The eta is October.
Sprint wants to have this network vision finished by this year so it just makes sense it would be happening in other states also.

You should have access to glance, it will tell you which sites are being upgraded and ETA's for lte and 3g nv. You have to be a lead or SM to access it.

Spotty 4g lte

Just got the One, coming from s2, and love this phone. However I'm on Sprint lte now, and get very spotty coverage. It constantly switches from3g to lte, sometimes no data at all.
Of course this is a sprint issue, but is there a Rom or other ticks that may help get more consistent lte connection?

Not really. I had to lave Sprint after being with them for 11 years due to my phone(s) not getting calls and poor network performance. In Dallas they really messed up big with Network Vision updates. Just my opinion.
Doesnt matter what hardware or software your on if the network is the problem your phone wont make it better.
Untill they get a handle on the system issues its not going to get better.

I regret leaving Tmobile. But hey, I hope that with a Tri-Band LTE enabled phone...things should be better. At least in the near future.

Random question, but are you using a case on your phone? If so, what kind?
Sent from my HTCONE using Tapatalk 2

It's been going on for me since the beginning of July. It's not your phone, it's the awful network. The network has gotten so bad here, my local new station did a story on it since so many people were complaining. Normally I'm not a fan of stuff like this cause the media tends to exaggerate but in this particular case it's as bad as they say. I can have the tower in site and my phone will dump between X/1X/3G/LTE. Constant dropped calls, cutting in & out, unusable data, etc. I have been with Sprint for over 10 years & the network is literally unusable as it stands. It has been getting better over the last few weeks but it's still awful. I can understand some disruptions in service but this has been an ongoing thing for months with no end in site. Poor planning on Sprint's part. As far as LTE being spotty, until LTE gets turned on 800 it's going to be garbage. HTC one doesn't support LTE over 800 which at the moment doesn't matter since it's not on yet but I'm hoping by the Spring new hardware will be out & LTE on 800.

if your on a sense rom, ##data#, click edit, enter MSL (if you dont have it, sprint should give it to you), you will see LTE settings and LTE scan settings, (dont remember exactly what they're called) Lower both those numbers to like 30 and 5 or something like that, it will scan more often and while connected to LTE should stay connected longer on a weaker signal....there is a thread on it somewhere...

Sprint website coverage map showed solid 4G LTE coverage

But my HTC ONE has no 4G at all, and I checked the whole area, not just one spot. I tried update my profile(No idea what's that for) and PRL, and nothing helps at all. Also, after update profile, I actually got stuck, lost cell connection for all. But that's a separated issue I'll say. I guess it should be that Sprint faked their coverage( I turned on my ATT phone with Tmobile sim, solid 4G LTE) just to get subscribers, and I'm pretty upset that with all the seemingly good news about Sprint, the real steps are so small, compare to other 4 carriers.
Do you think the phone itself is on the fault? I'm in the Irvine CA area, might be part of the Santa Ana market they are talking about just went online with 4G, which is just not true.

OC in general is pretty spotty whenever I go there, but that could be the One's weak radio. Either way check out this map.

Get close to a known 4g tower (within a few blocks,) check s4gru.com if you don't know where any are. If you still don't get any, there is something wrong with your phone. Sprint 4G on 1900Mhz is pretty fragile and the One drops it pretty easily, unfortunately the S4 actually is better in this regard.

Is it the metal casing that makes the htc one signal not as good as say the s4's? And if so, can a mod be done to help the antenna get better reception?

No idea really, my buddy at work picks up 4g on his S4 several blocks away from where I can in several locations. I'm actually going to flash another radio to see if it helps. May be worth a shot for you too.

The Sprint Coverage Map is an approximation. However, I will agree that a lot of the information is not specifically accurate. For example, the map has shown 4G LTE for my town for over 3 months now. Realistically, I've only been picking up LTE for less then a month now. I don't know what criteria they base the coverage map on (or their underlying intentions) but I have always considered it "somewhat accurate."
The HTC One doesn't help itself either. My wife's Note2 picks up solid LTE in our house; whereas my One can barely hold a 3G reception sitting next to her.

followed the link, interestingly, saw the coverage all along the road, I think it should be one or two person with the app driving through and sent back the signal strength. The real coverage should be wider, cause I don't know any antenna will transmit such a pattern

They have technician that have receivers in their vehicles and as they drive around doing work they collect the signal data.

Sprint really just needs to work on their coverage, they told my mates and I that they would have lte over here by the end of LAST April... nothing. We have 4g signal here, I know this because my old htc evo picked up 4g signals at home, but now that i'm using the one, it has no backwards compatibility with 4g and can only use 4glte, so the unlimited data im paying for is pointless because when i'm home I use wifi since its faster than the 3g i'm picking up (obviously). Really considering the switch to T-mobile when my contract is up.

Well, as demo27vol1 posted the s4gru link, there should be 4G coverage on many parts of the place I am at, that site should be from crowd source, not Sprint. What I found is, if I look at the s4gru's coverage very carefully, I can find one place with much stronger signal, where my phone can get 4G, (I'm not driving around with that map and my phone to try to map the coverage myself, I just went to that place and saw 4G and come back to verify with others' report and found it's relevant.) So I do think the phone is at fault now, means it has some problem with the 4G that it can't get the signal if it's weaker. I guess we should discuss this a lot because I would like everyone having similar experience to be aware of the problem.

It's generally understood at this point that metal phones get worse reception. HTC devices do not have a good track record of having good reception on Sprint as it is (Evo 4G LTE for example).
Most people who have compared the HTC One to an S3/S4 have found that the HTC One gets similar or slightly worse coverage (especially regarding 4G LTE). There are a few who say it's better on the One, but they are in the minority. The largest issue I have noticed on the One is that once it drops the 4G down to 3G, it requires an act of God to make it want to go back to 4G if your 4G signal is only marginal.
This is only a real problem because Sprint's 3G is so bad that a terrible 4G signal is actually faster and more reliable than full bars of 3G in many areas.

I agree, my GF has the GS4 and it holds on to the weak LTE signal for dear life while my One prefers not even to try to get it lol

2nd bad M8...sigh...

Looks like I have wound up with LTE connectivity issues on my 2nd M8. It's defaulting back to 3G and never trying LTE again. I'm in an area where the circuit fallback has already been installed and is up and running, so it shouldn't be that. It randomly just stopped working properly over the weekend. Sprint has told me there are no issues in my area, no work being done.
Is there any chance HTC or Sprint acknowledge this issue with their phones? What is happening under the hood to cause the phone to randomly get mucked up and never be able to get back to normal? Or is there a way to get back to normal?
Profile, PRL updates, rebooting, airplane mode are all (very) temporary fixes for a bigger problem. It acts and feels like a software issue, but is it something that can be reversed or does it get embedded into the firmware, never to be removed? I've tried flashing firmware multiple times without rebooting, over top of itself more than once, hoping to knock out or overwrite something wrong inside. I ran OMJ's h/k RUU last night and it connected to LTE as soon as it rebooted, but today it's right back to where it was.

Its really difficult to tell if its the device or the network but for the most part calling sprint is no doubt a waste of time. Over on the gs5 forums you hear the same complaints all day long. As a matter of fact, go to any sprint tri-band device forum and you will know doubt hear the same exact complaints.

Goto to a Sprint Store and Compare it Side-By-Side.
It's the only way to know for sure.

That may or may not make a difference, two of the same devices in the same location can be connected to different towers unless he uses an app to confirm that both are connected to the same tower and even then I have had experience with two exact devices connecting to the same tower and issues with that tower actually affected one device and not the other and nothing was defective with either device.

So far, I am, one of the lucky ones with an, s5 that hasnt had a bit of problems. I almost picked up the m8 over the s5 to give htc a try but keeping a watch on this forum made up my decision quick to stay with sammy. Don't get me wrong there are some s5 owners that have had problems but u m8 guys seemed to be getting hosed pretty bad.

I'd say keep a very close eye on them both. My 2nd one was perfect right out of the gate and stayed perfect for 3 weeks, then suddenly just poof it's jacked. It's not as bad as my 1st, but still frustrating. The 1st one wouldn't stay connected to anything, certainly not LTE. Now mine just wants to revert to 3G as soon as it possibly can. Very strange.

My daughter gets very good data with her g2, picks up lte in areas I don't and it gets me frustrated, it sucks I don't no anybody who has a m8 to compare mine with, I'm gonna have to wait till my wife gets hers with her upgrade

I think it's certainly possible but not that common. And if they do behave the same then he's probably ok. If they don't then he'd have to dig deeper.
One store had several M8's on display and the all behaved identical and very different from mine.
I should have 3 of them tonight to compare One being returned to sprint and one that will get sold in the end.

As a sprint rep who lives in an area that sprint spark and bands 2600 and 800 are being implemented I assure you it is not your device, it is the network. This is happening on all lg g2s, g flexs, s4 tri bands, s4 minis, nexus 5s and gs5s. Since the Soft Bank by out Sprint is doing a massive overhaul on their network. Sure service might suck ass for a few months but you'll appreciate it when its done. Hang in there, its more than likely not your device.

As a sprint rep who lives in an area that sprint spark and bands 2600 and 800 are being implemented I assure you it is not your device, it is the network. This is happening on all lg g2s, g flexs, s4 tri bands, s4 minis, nexus 5s and gs5s. Since the Soft Bank by out Sprint is doing a massive overhaul on their network.

Man I hope your right . Waiting on my replacement now to make sure it's not my device.

I see it daily man. From what I have been told, they had problems with cross connecting calls when implementing spark. Since then, they resolved that issue but then created the 4g data/voice connectivity issue. Meaning when you are on 4g, the tower isn't telling your phone when its receiving a call. Ever wonder why the m8 cannot talk and use data at the same time? However an s3 can. Does that phone have this issue? Nope. Its not so much our phones but more so the towers not communicating to our phone the way they should. This is why when you switch to CDMA only instead of CDMA/LTE, you receive voice calls and texts. Again, you can change this in settings/mobile data/network mode.

LTE only mode works perfect when I enable it. It connects to band 26. Switch back to LTE/CDMA and LTE refuses to connect. The reason I'm confused is because everything worked for 3 weeks straight in perfect fashion. The Sprint rep I spoke to said no work was even being done in my area. @johnnygabe89 can you help me understand how this could be?

Sprint Triband LTE devices do not support SVLTE (Simultaneous Voice and LTE).
In previous Sprint LTE phones, when a device was in Sprint LTE coverage it would park in both the LTE and CDMA Sprint networks at the same time. When a voice call came in, it would just go straight through to the device. And signal to the LTE network would be maintained the whole time while the call was active.
In contrast, a Sprint Triband LTE device can only stay on one technology at a time. CDMA or LTE, not both. So when a Sprint LTE Triband device is in Sprint LTE coverage it parks only in LTE. And doing so means it cannot transmit calls without Circuit Switched Fallback (CSFB) on the network side. CSFB and eCSFB (Enhanced Circuit Switched Fallback) are network controls that will allow a single mode/single path network to operate in two modes, both CDMA and LTE.
Here is how it works in the simplest way I can describe. When your Triband LTE device has an LTE signal, it cannot receive or make calls on its own. It is just using LTE data happily. However, what if someone calls you? How does it get through the CDMA network to your device? Via CSFB.
When the Sprint network tries to forward a call to your device but cannot see it via CDMA, it then checks for an LTE connection to your device. If it sees one, it tells your device to disconnect from LTE for a moment and reconnect to CDMA. Your device then jumps over to take the call on Sprint CDMA and the LTE session is interrupted. This happens very fast and seamlessly. Except for the loss of data availability. If you receive a text, the Sprint network is able to route it to your device via LTE.
Circuit Switched Fallback is a great solution to the issue of Sprint Triband LTE smartphones. But the problem here is that the Sprint network is being upgraded in Network Vision, and not all Sprint parts of the Sprint network can currently support CSFB. And it affects all Sprint Triband LTE phones
If yoou want you can read this article all the way thru

I don't think it's a circuit switch fallback issue. This morning I'm connected to band 25 and lte is working. It's when I connect to band 26 that it disconnects. So maybe its not a broken phone?

Well from what I have gathered from all my reading about the issues is that Band 25 is the Sprint Triband LTE, and Band 26 is the older SVLTE (Simultaneous Voice and LTE) and may not support the CSFB and eCSFB yet.
I could be wrong in my assumption

I feel like I remember reading that band 26 is the new frequency 800

I also think it's the network. When I first got the phone, I experienced the 3g of death, but have not experienced it much lately as it seems like Sprint is updating their network in my area.
I'm getting LTE in places now that I have never gotten on my M7.
This weekend, I went to LegoLand, which is a highly congested area, and was getting the 3g off death again, which I believe is related to the network. This is similar to when I went to Disneyland with my M7 last year and could never use Sprint service in the park to due to it being a congested area.
I find it helps to turn off roaming in areas where you get the 3g of death and just connect to the Home network. Try that and see if you get better results. It seemed to work for me this past weekend.

It appears that my area is getting LTE added to the Band 26 800Mhz frequency, though it's not fully up and running yet. So my M8 is scanning and sees that band available, and most likely prefers that band, so it connects but it's not fully implemented yet, so it kicks back to 3G. There was a moment this morning where I had fully working LTE, and lo and behold I was on Band 25, not 26.
If only there was a way to disable Band 26 on the M8 until it's totally up and running...

im facing these issues too..it sucks

[Q] KitKat update breaks LTE on Sprint Flex??

Ok,
So I've searched through this entire QA section and have yet to find a thread related to my question so I'm going to ask.
I recently (as in like monday 05/05/14) updated to KitKat on my Sprint Flex and noticed that my LTE wont kick on...I update my profile and PRL and it will kick on for a split second go grey (gray?) and then go back to 3G. I'm curious, has anyone else encountered this issue or could this be a simple single issue I'm the only on experiencing?
mind you, YES I do live in an LTE enabled area (no Spark ) and my old HTC EVO 4G LTE gets service just fine as does my wife's EVO LTE but my Flex just wont kick it on anymore. I even tried resetting the radio with no luck. If anyone can point me in the right direction, I would be very appreciative!
Other than this little hiccup, along with the KB issue, this phone is saweet!

How was your service before the kit kat update? FYI you should head over to the S4GRU forums. You will find better sprint support there. Its not a corporate sprint site, its a community of sprint customers that have lots of knowledge of the network.

I'm convinced that Sprint doesn't want people on their LTE network. They recently started throttling their unlimited customers data once they use over 5Gb. I used a Sprint phone for a short period of time before our company switched to AT&T, and that phone would disconnect from the tower it was using whenever the phone would go idle. I would try to use the internet and it would say "no connection", but the second I made a phone call on it the connection would re-establish. It's all very strange.

I left Sprint last year for identical reasons. As T-Mobile was the only other carrier to offer unlimited data without hidden throttle points. I had to pay the eta but it was well worth it. Sprint may be better out in the sticks because they have roaming agreements with Verizon but if you live in an urban area you will be ok.

My 4G LTE was badass before the update to KK. I'm very familiar with S4GRU forums. My service has always been great with Sprint, so that's not the issue, I was simply curious if this is simply an isolated incident or if this is becoming a known issue..I'm content with Sprint. I'll have to look at the other forums to see if I'm the only one having issues..

I had an issue when at my home recently with service. Since the g flex will not connect to data when on a phone call, i noticed that my service would go to nothing or 1 bar. I contacted sprint, and they told me that the 3g portion of the tower was out that i connect to when at home. They said it would be fixed by the end of the day. My advice is to contact sprint. Maybe they can shed some light on the subject. Try to contact them through the chat on the website. They seem more knowledgeable on there.

There is only one cell radio on the newer phones so no SVDO/SVLTE no voice/data. Wifi is separate so wifi data will still work.

OK.
so after I posted this thread i started checking the towers around me and found out i was not the only person reporting issues about this. apparently sprint is secretly updating the towers in Amarillo for spark. this didnt come from some idiot rep at the call center either, this i found out on my own. I verified it this morning and some areas in town my little sun lights up and my speeds are ranging from 15-25mb/s depending on the area of town im in.
I also got a phone call from a friend of mine in Austin because his iFag 5s wasnt able to connect to the interwebs even though he showed LTE to be active. they appear to be updating towers continuously in certina areas. thanks for the info on some of ya'lls part! i guess i just wasnt patient enough and jumped to the conclusion of KK breakin something in my phone.
