Hey everyone, my wife and I just got new M9's on sprint last Monday. Thought everything was going fine but then I noticed that whenever I was on LTE a lot bof my apps wouldn't work. I can watch Netflix and use tweetcaster, but a lot of other apps won't work(facebook,Pandora, and google now I can search but if i try voice recognition it says it can't connect to the server). Everything works fine on 3g and Wi-Fi. I have done speed tests of the LTE and they are always at least 7mbps down and 2 up. Have tried clearing data/cache and uninstall/reinstall of apps and still nothing. But it's not just my phone it's my wife this is happening on also. Any help would be appreciated cause I can't figure it out. Thanks everyone!

Try toggling airplane mode or mobile data on/off.

It sounds like the "data drop" issue some of us are having.

Try updating your profile or PRL , that's helped me in the past with data issues

Try toggling airplane mode or mobile data on/off.

I also have run into this issue, it happened with my evo LTE until I unlocked/rooted my phone and could install custom ROMs and now with my M9 , which is completely stock with just the OTA I only have one single bar and LTE constantly switches to 3G and I run into data transfer issues even when it says its connected.

Already tried updating the profile and prl. didnt help. i tried airplane mode and back on and i can now get facebook to load new stuff but no pictures or video will load. still have a better than average connection. im gonna try pandora to see if it works here soon. this is frustrating to have to do this. hopefully a fix can come soon.

Nevermind still doesn't work after airplane mode toggle I was wrong. Speed tests say I'm getting around 14mbps download speeds. This is super frustrating. I don't understand.works fine on Wi-Fi and pretty sure 3g too. Could it be the apps themselves? Cause it's just some. But they are major apps like Pandora and facebook. Should be ready for this.

I've had the exact same problem since day 1 with my phone two weeks ago. You probably also have the issue where you are typically only at 1 signal bar when on LTE but full bars when on 3g. I've also noticed it hits certain apps but not others. Usually toggling airplane mode and/or mobile data will fix it for me, but sometimes i have to completely reboot. even after the OTA update last week, the problem persisted. i brought my phone into a sprint store on sunday and they replicated the problem but had no idea the cause, so they swapped the phone out. same problem with the replacement, so i'd imagine we're stuck waiting for a software/radio/firmware update before this is resolved

Thank you for this. Feels good just to hear someone else describe my problems exactly. Wonder if it s all sprint m9 or just maybe ones people got early cause I got mine the Monday before release. Same on both my wife and my phone. I can't understand why some work and some don't. Now that you say it my LTE does most of the time just say one bar. And 3g is usually full. Hope a fix comes soon. Wish we could get conformation that ots a known issue. Facebook isn't a huge deal ask I can just use the mobile site but Pandora ducks to not have it.

Did yours come with headphones? The sprint site said no when we ordered and I asked customer care on twitter. Both said no headphones but ours both came with them.

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

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

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.

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.

I'd advise you all to return your phone that's what I did with mine

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.

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.

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.

HTC Chat is getting me no where. I even sent them these links:
https://community.sprint.com/baw/thread/204027
http://forum.xda-developers.com/sprint-one-m9/help/lte-signal-apps-wont-utilize-ideas-t3080920

I called, they supposedly create da ticket under my account to escalate. I'll have to see what happens with that.

    We finally got a rep from Sprint over to the board, about time. At least they are finally listening after way too long.
    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.

    ##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.

    Or Signal Check Lite app. And Band 41 is also considered Sprint's Spark Band.

    where in signal check lite is the lte band shown.
    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.

    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.
