I wonder if it's a DNS issue on LTE.

3G, LTE and WIFI are all pretty separate interfaces and have their own "setup".

What you might try doing is see if you can PING the server by NAME and by IP Address on each of those interfaces.

You may have to dig a bit to figure out what servers the various apps are using.

If it pings by IP but not by NAME it's a DNS issue.

Ever since Lollipop there have been some IPV6 issues that cause DNS problems. But those have been usually on WIFI only.

There are some tools in Google Play to disable IPV6 but it only disables it on WIFI interface.

Like on Lollipop M8, MMS would not work on WIFI for some folks and disabling IPV6 would temporarily fix it.

A really nice tool to debug with is called FING that you can get from Google Play. It has built in PING, Trace Route and a bunch of other goodies.

I used it to find a rogue device on my work Network.

If some apps work and others don't it's very likely a DNS issues. Unless Sprint is now blocking some ports on LTE.

You can also test HOST name and PORT for a service, this takes some serious digging to see if the port is blocked.

There is a tool in FING for that too called TCP Connection Tester. I usually have used TELNET on Desktop PC's to do the same.

If you google that service you can often find the host and port it's using.

Here is an example: Let's say SPOTIFY won't work on LTE

Get the Port and HOST from a search I did that showed this. I searched for SPOTIFY HOST PORT

Yeah mine came with headphones, I'd imagine all the M9s come with them
[Sprint HTC One (M9)] LymeWire:
I'm so happy this is happening to other people as well and not just me, was going crazy trying to figure what the hell was going on with my phone. Hopefully some update will fix this soon as it's very frustrating when I text everyone with Google voice through hangouts and my app doesn't pull in the messages
[Sprint HTC One (M9)] Sim-X:
I'm happy it's not just mine either I mean it sucks but last thing I wanted was a bad radio.

Same issue here, when on LTE can't send snaps (just an example) also push notifications don't seem to come through. Though it might have been due to the rom I was using but doesn't seem to be the case. Even RUU'd it and it didn't help same exact issue. 3G just fine, wi-fi just fine. This is driving me nuts. I guess it sounds like it's a Sprint issue and not hardware which is good but calling Sprint Tech support is usually usless unless you get to the higher ups.

My friend has a pure stock locked non-rooted s-on phone he says he has been having issues as well.

We might wanna get something like this going over at Sprint Community hopefully try and get the issue moved up. I was thinking it might be a DNS issue as well.
[Sprint HTC One (M9)] ReproOne:
Has anyone found a solution?
[Sprint HTC One (M9)] Sim-X:
I have yet to find or see a solution. Sprint or HTC hasn't said anything about it officially. Really sucks cause a bunch of my stuff just doesn't work right over LTE including push notifications won't come through. I have not enjoyed this phone thus far.
[Sprint HTC One (M9)] dubb305:
I'd advise you all to return your phone that's what I did with mine
[Sprint HTC One (M9)] ReproOne:
I've swapped for another M9, doing the same thing. I'm on the phone with Sprint now, they have escalated to a second tech. That tech claims they are not aware of any issues on the M9, but did say they heard of one S6 having such issues. The tech advised to swap it yet again.
[Sprint HTC One (M9)] Sim-X:
If enough people return them they might actually look at the problem. I remember when the evo4G had an issue similar to this, you couldn't stream music Sprint's proxy would mess it up. Took them a while to release a fix. Really this isn't an acceptable problem, I'm mean half the apps are worthless cause they won't work over LTE. I'm past my return period and I'm unlocked and this appears not to be a hardware problem. I just wish they would confirm something that they are looking into it. I hate calling Sprint for tech support, it will be the usual non-sense of resetting the phone and doing data profile updates. Then they bump it up and tell you they will call you back when half the time they never do anyway and even if they do it's usually not with a fix. I remember I had a problem getting Direct Connect provisioned on the M8 when it came out. Regular CSR couldn't add the code correctly, they did end up fixing it eventually but no thanks to the techs I worked with nor did they really follow with me more than once. An issue like this needs to make it to the correct people which appears that has not happened yet.
[Sprint HTC One (M9)] ReproOne:
I agree. I am chatting with HTC Support now.
[Sprint HTC One (M9)] Sim-X:
Let me know what they say, I know Sprint has yet to acknowledge the issue. All this phone swapping business for probably no reason is gonna cost them a lot. I guess it builds a nice refurb stash.
[Sprint HTC One (M9)] ReproOne:
HTC Chat is getting me no where. I even sent them these links:

[Sprint HTC One (M9)] BUBBA DUB'S:
I was having issues with some apps not working properly on 4g but for some reason worked fine on 3g. Checked for updates and found another one for Android system webview from v40 to v42. Went to download it and none of the apps would download on 4g , switched to 3g, took updates and now some of the apps that didn't function properly on 4g (navigation/video on facebook mobile in chrome) work fine. I haven't really figured out what that app does besides what google says, but I also seem to find conflicting information about it. Regardless I figured I'd ask to see if anyone having app issues would like me to see how they work on my device on LTE network
[Sprint HTC One (M9)] Sim-X:
I noticed that webview updated a few days ago but I didn't notice any difference. Apps are still borked over LTE for me
[Sprint HTC One (M9)] ReproOne:
Same here.
[Sprint HTC One (M9)] :
update.

Hey guys. I started the posts here and on sprint community so its finally good to see others are having the same problems. i was getting no where finding a solution online or talking to people, htc(didnt bother talking to sprint.) Finally go so frustrated i tweeted at htc us president and the htc us twitter. Mo Versi who is the vp or product management tweeted to me and someone under him to look into this. Long story short they sent me a new phone to "investigate" the problem on mine. got it yesterday and have not had time to swap yet (will do it tonight) then I'm sending mine out tomorrow to get looked at. Been emailing back and forth with the director of product management at htc telling him about the problem and that its a lot of people and not just me. told him about the message boards filling up. hopefully they will figure it out soon. dont have high hopes for the new one they sent me cause lots have swapped out at sprint and they still dont work. we'll see. I'll try to update tonight.
[Sprint HTC One (M9)] ReproOne:
Thank you for the update.

I'll be waiting, as my swapped unit has the same problem.
[Sprint HTC One (M9)] Sim-X:
Nice to see they are paying attention to someone. Let us know if the swap fixes it but this seems to be a pretty widespread issue. It's ridiculous no one from Sprint or HTC has said anything officially about this yet.
[Sprint HTC One (M9)] ReproOne:
I just called back into Sprint to follow-up on the case I opened, and they are having to do the whole call over again....

---------- Post added at 07:32 PM ---------- Previous post was at 07:28 PM ----------

I just called back into Sprint to follow-up on the case I opened, and they had to start the whole call ticketing process over again. Then they disconnected.
[Sprint HTC One (M9)] dubb305:
I went through 4 phones and they all had the same problem
[Sprint HTC One (M9)] ReproOne:
What are you doing then, keeping the 4th one?
[Sprint HTC One (M9)] dubb305:
I returned it and got my money back I think it's a bad batch of phone that were made cause they delayed the release of the phones to install updates on them and I think those are the ones that's having the problem
[Sprint HTC One (M9)] Sim-X:
Sounds about right. When the M8 came out it wouldn't provision to Direct Connect correctly even know it was listed as being a DC phone. Got the usual run around, some reps telling me it doesn't support DC, others trying to add it but it wouldn't take. Same non sense making a ticket, poor follow up. They did follow up a couple of times but the issue was not resolved because of my ticket. I just gave up since I didn't really need it that much anyway. A few months later it was fixed and it was able to be provisioned correctly to work. That's why I haven't even called them and I refuse to go to the store unless I have a known hardware failure that is easily provable to get a phone swap. Since I have already unlocked my phone and I don't have TEP anyway there is no shot I'm going to the store for this issue. Also you guys have reported swapping it out multiple times with brand new hardware with no success so signs point to a software problem which is good cause hopefully that can be patched with an OTA. Signal performance on my M9 is pretty much identical to my M8 from my usage. They will have no choice but to look into this very soon as all they are doing is costing themselves money by building a refurb stock pile for really no reason at all since it appears not to be a hardware problem. If I was still within my return period I may have tried swapping it just to help this issue get noticed since it's no questions asked when it's in a return period time frame. The right people need to get this information for it to get fixed, at least if Sprint published something that it's a known issue they could push out a notice to stop swapping phones for no reason and either issue customer a refund or let them know a fix is in the works.

I just sent a tweet to Jason Mackenzie linking here and to here http://sprint.co/1Fplsoa Feel free to do the same. https://twitter.com/jasonmachtc

[Sprint HTC One (M9)] ReproOne:
Would he like another person to reach out to him? If so, I'd appreciate sending an e-mail as I want to see this resolved.
[Sprint HTC One (M9)] Sim-X:
HTC got back to me via social media, I sent them over my info so I'll let you know what they say. Really I just told them to go through and read the threads, between all of us we have done plenty of troubleshooting.
[Sprint HTC One (M9)] Sim-X:
Sprint & HTC have been absolutely worthless in helping or even acknowledging there is a problem and it really is pissing me off. I figured out a temporary or really permanent solution I suppose. I did some testing by setting up a VPN to route traffic over the VPN while using LTE. What do you know, my mighty text works, my snap chat is almost instant, pandora streams perfect, chrome2phone works. Go figure - so this is what I will be doing for the time being. Absolutely ridiculous this haven't even been acknowledged by either Sprint or HTC yet. The average user most likely will not be setting up a VPN connection on there phone however I thought I would share if you are sick of your stuff not working. Something is messing with the network traffic, not sure if it's Sprint or what. I tried removing the Sprint proxy before flashing bad boyz on a stock rom it didn't help so VPN it is.

[Sprint HTC One (M9)] Sim-X:
We finally got a rep from Sprint over to the board, about time. At least they are finally listening after way too long.
[Sprint HTC One (M9)] ReproOne:
I heard back from the network team twice today.

The first was to tell me that the network worked fine and to take the phone back. I explained to them to read the forum links I provided to here, Sprint community, and pocketables as it was more than just my phone.

I was called back later in the day and told the network team wanted to re-provision all data to my phone (not a ##72786# procedure. I went along with it, so they called me on a different number as I powered off my phone. They then did something on their end to re-provision just the data, and then had me turn the phone back on so it would activate. Once that was finished, I was asked to use the phone and they would call me tomorrow morning to check on it.

So far since then the apps have not timed out on LTE, and I have switched airplane mode on/off, wifi on/off, restarted phone, etc. to try and get it to fail. I'm not fully convinced what they did fixed it yet, but so far it has not timed out.
[Sprint HTC One (M9)] Sim-X:
Interesting... since most likely it's not a hardware problem that makes sense that some kind of re provision would take care of it. I'm just surprised they actually called you back and did something useful. Must have been tier 2 support or higher as tier 1 is usually worthless. Well that's good, maybe they can document and then can push out a profile update or we can manually do it to take care of the issue. In the meantime I have just been connecting to a VPN and everything works fine when on LTE.
[Sprint HTC One (M9)] ReproOne:
The network team followed up as promised this morning, and the timeout issue did not happen since they refreshed the network to my phone yesterday late afternoon.

Since that was a short test period from then to this morning, they are going to contact me again tomorrow morning to be sure. If the issue remains to appear resolved, they will pass the information to the device team.
[Sprint HTC One (M9)] ReproOne:
Well, the data was working fine until a few moments ago. This time, however, it lost all data as even the browser could not load. It was on Band 26, LTE 800 in the same office location it had been working all day.

I called the network team to advise them, and we agreed I would call next time when the phone was in the data lock state so as they could troubleshoot.

I had switched airplane mode on/off to recover the data before calling in.
[Sprint HTC One (M9)] dafluke24:
Thanks for keeping us posted. Hopefully they can get this resolved quickly with real time troubleshooting. I've been issue free since disabling B41, but if it's available in my area (and it is), I would like to use it as well.
[Sprint HTC One (M9)] graycorgi:
I think I noticed this for the first time today. I had 5 bars of LTE and my facebook would not load an image and my Pandora would not load the next song. As I was driving I think I hit another tower because it went from 5 bars to 1 in a second. Once that happened, everything loaded right away. Weird issue.
[Sprint HTC One (M9)] schmeggy929:
Its weird it is on different bands for some. Today i switched to the .17 radio re-enabled Band 41 which I had no problems since disabling. Same problem, I use Waze for the long drive home and it froze searching for gas station prices while on Band 41. For me in the NJ/ NY area Band 41 is the problem. It shows active on Signal Check lite but just keeps searching and searching and times out. So its back to .30 radio and disabled band 41. Bands 25, 26 and 3G no problems ever. Decent band 26 all over the area with 7mbps down and 5 mbps up on average.
[Sprint HTC One (M9)] dafluke24:
Same here in the Dallas area. Something is going on with b41 that's for sure. B26 has been consistent for me with similar speeds
[Sprint HTC One (M9)] Sim-X:
I tried disabling Band 41 on mine, didn't help any. Issues were exactly the same so I just turned it back on. Odd it helps for some
[Sprint HTC One (M9)] Sim-X:
Great news! Early signs this issue is being or has been resolved. I can now confirm I am no longer having the problems first reported. Several on my borked apps have starting working. Another user has confirmed this as well on the Sprint Comunity posts for these issues. I did no profile update or reset so as we suspected it had to be something on Sprint's backend. We haven't got an official post yet from Sprint but hopefully this is resolved for good. I haven't tested every app yet but will keep an eye on things.
[Sprint HTC One (M9)] dafluke24:
Good to hear. I'll turn on b41 and see if the issue is fixed. This is good news that they're actually doing something about it.

Edit: re-enabled band 41 and did a profile update. Phone decided to reboot to apply changes. Since then been connected to 41 and haven't had any time out issues. It's still showing 1 signal bar, but every app seems to be working fine. So far so good.
[Sprint HTC One (M9)] graycorgi:
My phone has been working well today. Also saw it connect to b41 for the first time, although I'm sure this is unrelated (b41 is pretty hit or miss in my area due to unfortunately bad tower placement). Hoping whatever the problem was got fixed!
[Sprint HTC One (M9)] BUBBA DUB'S:
How do you see it connect to b41? Are you referring to download speeds increasing? Disabling b41 had no impact on my connectivity issues it still will spaz out occasionally. Also from my understanding b41 is the TDD LTE but it is ment to increase down/upload speed in conjunction with b25 which is their main LTE and b26 which is the lower MHz b26 which helps increase coverage area.
[Sprint HTC One (M9)] graycorgi:
##DEBUG# will tell you what band your phone is connected to under LTE Engineering. You will not be connected to more than 1 LTE band at a time.
[Sprint HTC One (M9)] schmeggy929:
Or Signal Check Lite app. And Band 41 is also considered Sprint's Spark Band.
[Sprint HTC One (M9)] BUBBA DUB'S:
That's good to know, I messed around with the band's enabling one at a time and even with it just on band 41 (7mbps) my download speeds were the fastest with them all enable (28mbps).
[Sprint HTC One (M9)] Aldo101t:
where in signal check lite is the lte band shown.
[Sprint HTC One (M9)] dafluke24:
Sometimes it'll show the band number, sometimes it doesn't. Looks like b41 is acting up again for me. Back to disabling.

Edit: sorry for the big pic. Can't seem to shrink it using the tapatalk app.
[Sprint HTC One (M9)] Aldo101t:
yep, doing same for me.
[Sprint HTC One (M9)] Sim-X:
I use Signal Check Pro you can set up a widget (not sure if the Lite comes with Widget or not) but it's a great app to own and it's cheap. Shows you what band you are on, on top of signal level and your wi-fi signal level. I keep it on my main screen. If you click the widget it brings you right into the detailed screen. It doesn't really affect battery either as the signal levels it's just reading from the phone.
[Sprint HTC One (M9)] OMJ:
[MENTION=1320407]Sim-X[/MENTION] coon rapids...nice...that's where I grew up :D mom & sister still there

what kind of speeds u get there?

mine:
[Sprint HTC One (M9)] Sim-X:
Nice! LTE 1900 on my home tower, not so great speeds usually part of it due to signal strength.

[IMG="LTE 1900"]https://s3.amazonaws.com/uploads.hipchat.com/61732/425623/KG9Rk8Ks1jBtJKQ/2015-05-02%2014.31.44.png[/IMG]

They could be a lot better, I have pretty good wi-fi so I guess it's not that big of deal but signal strength on Sprint (LTE anyway) regardless of band just seems to be so crappy compare to the other carriers. I'm less than 1 mile away from my Tower. Even know my Tower has band 41 I can't pick it up not even a mile away sometimes even rolling to LTE 800. The verizon tower is also around a mile (aprox Hanson/Bunker) away and strength and speed is way better. I usually pull 10-20 down and 15+ up on Big Red.

[IMG="Band 41 - This was a while ago either Brooklyn Center or Plymouth"]https://s3.amazonaws.com/uploads.hipchat.com/61732/425623/U42VvtP6tU1o1M2/2014-10-12%2018.22.29.png[/IMG]

Band 41 - This was a while ago either Brooklyn Center or Plymouth

Band 41 is pretty awesome when it works but even the water tower cell site off Hanson you can be right next to it and have 1 bar, it's like wtf. Meanwhile if I go EVDO to my home tower it's almost full strength. I know that has better penetration but still.

I know the "bars" don't matter but the bars translate into a signal reading which is what I go by and having such low levels everywhere even with LTE 800 can be frustrating.
[Sprint HTC One (M9)] graycorgi:
Today I had an issue where Pandora would not load the next song even though I was on LTE. This was after my phone connected to a new tower, but both Facebook and browsing were working so it could have been Pandora being dumb. Curiously, ##debug# crashed as soon as I dialed it, and right when that happened Pandora loaded an ad.

I too have noticed Sprint's signal strength always hovering at 1 bar on LTE on pretty much any band I am on unless I am directly staring at a tower less than .5 miles away. I think this has more to do with how Sprint has the phone translate signal strength into bars than an actual problem with signal strength, seeing as that 1 bar will stay there between .5 miles and 2 miles away from the tower, where the signal strength is surely changing.
[Sprint HTC One (M9)] Sim-X:
I noticed the same issue. Quitting pandora and going back in (didn't have to kill the task, just normal quit) Seemed to solve the issue (no airplane toggle). Don't really know how to replicate the issue, I was just messing around with Pandora most the time it worked just fine on LTE but sometimes it wouldn't play the song. Could be just a Pandora issue, I know previous builds I had issues with it just freezing and a box would come up saying not responding. Could be Pandora just being dumb, the last few builds have been crappy.
[Sprint HTC One (M9)] ReproOne:
The Network Team followed up with me today, and notated they were aware of the issue and have been working it. Since they re-provisioned my data from the network side, the applications have not been timing out. The individual I talked with also stated they used the same approach to fix it for another caller, and that they were working it from the backend. So, for now, it appears they have a handle on it. I'm glad they took notice and worked it, it is appreciated.

The phone does seem to have a difficult time keeping LTE in a weak area compared to other phones, which hopefully can be fixed with a radio update. At times it will go to 3G or 1X where my family's iPhones remain on LTE. However, for now, it appears the actual application timing out issue has been resolved or being resolved.
[Sprint HTC One (M9)] trev23sks:
So is best to call and let him know the issue so they can help us aswell?
[Sprint HTC One (M9)] ReproOne:
If you are still having the issue of some applications timing out, yes I would call the network team and have them provision the data from the network side.
[Sprint HTC One (M9)] mswlogo:
My phone has been normal for several days since the last profile update I did over LTE.

I see it switch between bands including 41.

I often get 1 bar on LTE. And speeds can be quite good (in the mid 20's) with one bar.

Speeds has as much to do with signal sttength as much as network load.
