The new firmware may be showing the correct signal quality now. My wife's device is the same since the update.
If you don't loose reception then I would not worry about it. If you want to you could get a new sim card for free @ a T-Mobile store. Just tell them Tech Support said to go and get a free sim replacement.

It could be worse, your mobile data AND wifi could become inoperative for several hours after accepting the new update. My wife found that issue out when she updated her stock L769 yesterday. rofl XD

Have you had any better luck with the signal i only get good service when i check tje 2g

Do you mean the Jb wifi bug?
Every second time when waking from standby Wifi signal strength reads 0db and speed –1mbit. Works fine though and toggling lockscreen fixes it. I fear however that this makes the phone use max wifi transmission power, draining the battery more.

My wife uses simple bar-style phone which costs few dollars. She hates touchscreen phones. But when she throws that phone at me, I get wound and blood on my forehead but that damn phone does not break. Then I hide my L9, coz I simply dont want her to throw L9 at me at that speed. It will sure break.......kidding :laugh: he he he

Network signal 117dBm on 4g and 75 dBm on 2g why the problem. I need help

[Q] Losing signal on my Amaze 4G

Okay, here is my problem: Every once in a while I will completely lose all signal on my phone. It wont pick up 2G, 4G, nothing. Wifi and bluetooth both seem to work though just fine. I've searched and haven't found anyone with the same issues so I'm wondering if it's just my phone or if nobody has commented on it. I first noticed this about two weeks ago, when my phone refused to find service. I was stuck with the little X next to the signal meter. I figured I was just in an area with poor service and didn't think much of it. An hour later, still, no service. This time I went outside where I know I have good 4G service and nothing for 5 minutes. I enabled airplane mode and disabled it, still nothing. Turned the phone off and back on as a last resort. Still nothing. I ended up finishing the day with wifi calling as that still worked. Sometime later my phone began receiving service again so I thought it was a fluke issue.
Then, just yesterday the same thing happened. This was when I rebooted my phone (which bypasses the fastboot feature) and service was restored right away. I called T-mobile and they said there weren't any network issues in my area and they had never heard of this issue before on the Amaze.
So, this is where I'm asking if anyone has heard of this before. I'm running a stock ROM and it hasn't been rooted. Thanks for any comments!
This might help just a touch. I do live in an area with decent service but my couch and bedroom are deadzones for some odd reason. I bought these signal boosters for 2 bucks figuring "what the hell, I'll give it a shot". No more dead zones, and data went from E to G. Not a miracle worker but for a couple bucks it keeps a signal at least.

Wireless Coverage
I have 2 brand new Amaze 4G for a few months now and had no problem with the coverage. I know the coverage is good with full signal bars and have not found any issue with coverage.
Sometimes, different phones have different received signal sensitivity. Also depends on user behavior. If you are always using a handsfree device (cable or BT) and your phone is in a bag, then your coverage is reduced by your action. The best coverage you can ever get is when you have line of sight (unobstructed) to the cell towers.
There are a few issues with your problem:
1-Poor inbuilding coverage
2-Poor coverage in your area
3-Network optimization issue
4-Hardware issue
If you are going from 1 bar to no bar, then most likely you have coverage issue. You lost signal since the level is already very low.
If you are going from full bar to no bar, you might have hardware or network optimization issue. Try your phone is the city or area with known good coverage first. If the behavior persists, then you have phone problem.
I used to manage wireless network for carriers.
same issue
I've had the exact same thing happen to me. Red x, no signal except wifi, in places where signal is not normally an issue. Battery pull doesn't work, return to signal seems arbitrary. Had the same thing happen with my Desire. I have no answers, but you are not alone.
Yup, it happened with my first Amaze. I got it back in January and started playing with it - rooting, custom ROMs, etc. Then later that day, the signal just died on me. I thought I must've screwed something up, so I flashed back to everything stock. No luck. I waited for half a day, then it randomly started working again at night.
You probably noticed tha tI said that happened with my first amaze. That's because after that signal issue, I discovered that my camera stopped working. I returned it to T-Mobile and they sent me another one. This one is working great though.
Well thank you for all the input so far. Id like to say that this isn't my first cell phone and I'm not new to weak or poor signal areas, especially from T-mobile. I was using my phone at work at the time, which has anywhere from no signal to 3 bars depending on where you are. This wasn't one of the cases that I was standing in a dead zone when I checked my phone. I had no signal for several hours, including over 30 minutes of standing outside trying everything I could think of. I have had excellent signal outside in the past, exactly where I was "Hiding". I got the Amaze because I was tired of playing with my old HD2 and having to work around bugs and possibly not receiving calls. So far, I'm not happy that the radio seems to quit responding all together and leaves me without a phone (minus the wifi calling but I'm not always around a hotspot).
I also experienced a dramatic signal loss at home, going from full signal strength to maybe one bar right around the time that I first had issues. I don't know if this is related or if this is a completely different thing.
I am 99% sure this is an error with the phone - probably software related with the radio driver(s) or radio firmware. I guess I will try taking it back to T-mobile and seeing if they could exchange it for a new one. I was just really wanting to avoid that as I finally got my phone setup how I like it. Again, Thank you for the input and let me know if you are having the same problem or if you know of a solution.
I am on my third Amaze and also tried a Galaxy SII X due to the same problem at my home. Even the Samsung did the same thing. In my house and especially in the driveway, the signal varies wildly between -85dbm to as low as -111dbm. The frustrating thing is once it loses the signal, it doesn't seem to reacquire it without a reboot.
I'm with Telus, and they said they will check on it, but I'm not holding my breath. In my immediate area, outside my house, the signal isn't great, but it will usually hang on. I have been to different cities, and all has been well with it. Coming from a rock steady 2G Touch Pro II, I am disappointed as well..
I am new here to this site, but I am having a similar problem with my Amaze. At work I always have a weak 4G signal, but the last few days it has been gone altogether. I have full phone service (4 bars) but no data. The 4G indicates I have signal, but I can't connect to anything on the web. I called HTC and they had me pull my battery and sim card so they could send a "reset signal" to my phone. After my phone came back up I had faster service than ever, but it only lasted a few minutes and went away again. I am thinking this is a phone issue. Oh, the Amaze is my first Android. My only previous smartphone was my Nokia E71x.
I know if I have WiFi calling selected, an x will show up on my signal if i turn WiFi on. I've personally only had slow data in the area I work. I blame it on the fact that it is a busy corporate park with lots of hotels, cuz my signal is fine elsewhere. Try calling tmobile and seeing if they have known tower issues in your area. I know I had that problem with sprint and they sent me a free airave. Maybe tmobile could do something similar if its.a known problem.

It's most likely a network issue. I get the same thing, it will timeout/refresh the network where it will not get a signal for about 30 seconds a few times per day. I blame the network, since the same thing happened to me with my mt4g

Thank you! This fixed it for me. It was happening only today while I had WiFi enabled, it would turn the mobile radio off completely and the box would be grayed out so I was unable to turn it back on. I had my sim updated today to enable wifi calling so after I read your post, I turned the wifi calling off and the mobile radio signal came back immediately. Strange bug.

I was told It's by design. It saved battery life by not constantly searching for a mobile network it won't use (due to wifi calling). It's not like you can hand off the call to the local network. I do notice that if i start walking outside, once my wifi hits a low signal it logs back on the network.

There is actually an option to specify how the WIFI calling works: either all the time or only when cellular signal is gone. Sounds like you have it set to be on all the time. This means that if you have a good WIFI connection, the cellular radio is shut off and all traffic goes through the WIFI calling app. The other option (which I use) only uses wifi calling when there is no cellular signal.
I have lost cellular signal 3 additional times since my last post. Its not just that I'm in a bad spot and I have no signal for 30 seconds. This goes on for 30 minutes or more - up to several hours. I have found that rebooting the phone fixes it as I believe it completely (as much as possible) removes power from the radio and requires it to be completely re-initiated during the reboot. Simply shutting it off doesn't work as the quickboot is enabled and most likely doesn't perform a complete re-initialization of the radio. My only guess at this point is that there is some kind of possible leftover code from development which never was removed from the radio (this happens more times than not). It could be a timeout or simply causing the radio to hang because of 1. excessive heat generation, 2. excessive power drain, 3. buffer overflow, 4. excessive RF transmit power... In any case, one of those issues could trigger an event in the radio to cause it to simply stop responding.
I am in the process of trying to get T-Mobile to get me a new phone as I am outside of the 30-day window. I have also confirmed it with them that this was not a tower issue.
Thanks

Hmmmm who is dear? Lol.... Ne ways, well first off, I commend you for digging this thread up rather than just starting a new thread without even looking first :thumbup::thumbup::thumbup: I can't say I've ever seen someone who hasn't even been a member for 1 full day do that. Shoot, I see senior members start new threads or pointless threads without searching first, so good job haha.
Ok, back on topic now, if it's only dropping when you go in your room, then I don't think it's anything wrong with the phone. Not sure who your provider is, but u may be able to call them and have them look up your address and tell you what kind of signal u should get outside your house, and what to expect inside your house. I know t-mobile does at least

Well your situation is a little different than other peoples in this thread if u can't connect al all. Ok wait so first off, it won't connect to a network at all? AND you only paid 50 bucks for it...? Sounds a little fishy to me bud, why did he say he was selling it...?
Next thing, I don't know why a t-mo rep would tell you to root the phone, rooting has no effect on your signal strength or your ability to connect to a network.
And lastly, is the phone a T-Mobile branded amaze owhat carrierr...? and will it not connect at all, period, or can u make calls just not data...?

Sick connection issue.

Today I'm having issues with 3g connectivity on my Lumia. The phone just doesn't connect no matter what. I tried restarting it, pulling the SIM but no luck. At first I thought: my bad for cutting the SIM card myself, maybe after some time it got messed up. When I came home I grabbed my gf's 710 and it was behaving the same way (her SIM card is brand new). Coincidence? I don't think so. A friend of mine with the same carrier (H3G) just told me he had no issues whatsoever connecting using 3g connectivity, and he has a Nokia N97. This is starting to piss me off...anybody else having connectivity issues today? It must be something Microsoft/Nokia related. God I'm about to throw this thing off the window.
3g connectivity
I had the same issue the day i bought it..had to reset the phone for 3g to work again and today i face the same issue again!

My God I hope this is not the case, that would be annoying as hell...this is just too weird, why would this happen on two phones at the same time? Geez this is worse than on Android...
Hoping the same..Even im waiting for a workaround to make 3g work on my phone.
Ok, I just woke up and tried again, it works now Microsoft/Nokia have to do something about this tho, this is not acceptable...
Doesnt work for yet..still unablle to figure out why whatsapp is running fine but no other 3g activity happening. Please let me know if u had to do something for 3g to work.

Nothing special really, I simply let it charge overnight, picked it up in the morning and it was working. Yesterday I tried everything: plugged it to the pc, switched flight mode on and off, tuned it off for a few minutes but no luck. The last option would have been draining the battery completely then plug it to the pc to turn it back on, but that wasn't necessary. Really weird...i still need to check if my gf's 710 is working now.
Seriously, this is not good. I noticed it since yesterday again. I had it when I first got my Lumia. I have weird issues such as being able to stream music non-stop over 3G, yet being unable to make or receive calls. What I do to make it work? I switch to airplane mode and back.
I got both Lumia and MicroSIM for free; didn't have these issues for weeks. I got the newest firmware (12072) using cab sender, might be any constellation? Typed on my Lumia btw
Apparently my gf's phone is working as well now, gotta love these random bugs...
Happened the same here, suddenly I got no signal at all, tried everything, didn't want to format the phone so I just waited and some hours later connection was back, but 2g only, next day all was fine with 3g also workin

How long has it been going on like that? Mine started working again after about a day...
6 days now, really getting pissed off. I think its just a faulty model. I'm gonna try to factory reset. Anybody have any other ideas?
6 days is a pretty damn long while...do a factory reset and if the issue is still there you should definitely get it checked. I had no idea this thread would have gethered all of these people, this is something that Nokia should be really looking into...
So i called vodafone and they told me that when i took my new 2 year contract (and got the phone) i also got a new sort of contract that slowed down my internet.. while this makes sense it also doesnt because the speeds they were talking about should still have been fast enough.. But since i also only had 500mb i upgraded and the problem is now gone. everythings really fast again.
One question though: When i pick highest network setting i can only choose 3g.. but with my current contract plan i should get "H". anyone have any info on that?

Ok let me explain what is going on. In Holland (Im dutch also) we have "H" as the symbol for an ACTIVE 3G connection (meaning downloading/uploading data). Where "3G" means an inactive (or not consuming data) 3G connection, this is not worse than H, its the same.
On the US version you will see 3G when not downloading and 3G+ when downloading (which is the same as our H). Whatever letter there is does not matter as long its not a G you have your max speed.
Now also notice that there are a lot of areas where providers can not peovide the maximum speed (crowded/low signal/etc). Make sure you check your speed with full bars and dont be paranoid with data tests. If the speed is reasonable and IE9 can load a decent page, than its ok. If it wont load a page than your 3G does not work.
If your 3G does not work (what was the case for some of you) than set the APN settings manually to your peovider (or use the Nokia Network Setup app), goto Settings --> Cellular --> Edit APN.
Now 3G will work.
Again dont be bothered about whatever Icon it shows, H, 3G or 3G+ its all good (or 4G). As long as there is no G or E you will have the highest connection your phone can receive. This does not guarantee your provider can deliver you what you pay for (probably you get much lower speeds) and they might also cap your speed if you surpass your datalimit (as does TMobile NL with "unlimited internet").
Good luck

How to increase consistency/strength of the phone signal

My phone - I have ICS - S-OFF Amaze with Energy ROM and I had tried to apply blas0id tweaks.
The problem - In certain areas I don't have phone signal for a few minutes, then suddenly it will show 4 bars for a few minutes. In general the signal seems fickle.
Before ICS upgrade, when I had GB, I always had 4 bars in the same places. I *think* I had good signal with ICS before I did blat0id tweaks, but I am not certain of that. (ICS and the tweaks were within a few days)
My wife's Iphone still has excellent signal in those places. Tmobile Mytouch also has excellent signal in the same places. So something has changed on my amaze and not the cell towers.
What I have done so far -
1. went back to stock ICS by flashing the img file. That did not improve the signal. So then got back to energy
2. Tried another ROM - speedrom. No improvement in signal
3. Tried few apps like fresh network. They did not help
Please help me
What can/should I do? I love my amaze, but if I dont get consistent signal, I will have to replace it
Are there any tweaks that I can try?
How about the custom kernels that have been made for ICS recently, would those help?
Is there a way to increase the power to look for and catch on better signal? I can trade battery life for better signal
Thanks
I have same issue but with WiFi only. I never had GB I hope there is a work around
Sent from my Dark Unicorn Resurrected v.2.5 using xda premium
Found a workaround
This was dumb luck, but when I was trying to play around the app opensignal, it wanted me to set 2G for some of its functionality, since that functionality does not work over 3g. So I went to setup and set Network mode to "GSM Only" from "GSM/WCDMA Auto"
And walla! right after that my signal jumped from 1 bar to 4 bars and has stayed there. I went back to WCDMA and signal dropped, so now I change the network mode only when I need 4G. Its a pain, but at least, the signal is good when I need it.
So with that information, can someone help how I can tweak something to get my 4G and also good signal?
Thanks
try updating the radio if you have done so, even though you are going to have to go through the process of locking the device again and unlocking the bootloader again, that would be an idea to try, we still dont know what changes R2 radio update has done but its deff worth a shot

I have always had this problem as well sometimes I have 4 bars of signal then it drops to the X as in no signal,can't make calls or sends texts until it picks up again, happens totally random don't think it has to do anything with tmobile coverage since I live in the center of Miami. Also most of the time I have 2 bars of signal in most places, I believe it's faulty hardware

yup, that's what this setting is supposed to do, but it increased the quality of my phone signal, that is what I am trying to make better/consistent. Because even after all the bells and whistles, calling someone/receiving the calls is the primary purpose of the phone for me and if that doesn't work, the phone doesn't work for me

A new sim card is a good idea.. so is removing the back cover and cleaning off the contacts with a q-tip and some rubbing alcohol. Taking something and SLIGHTLY bending out each of the gold contacts so they make better contact with the case, making sure there is no debris.
Another thing to look into- there is a TON of hacks for cellphone signal that can be done in build.prop.. playing with those settings is probably a good idea.
The last idea- the signal is actually NOT different. The number of bars it shows you is now just more ACCURATE. You still lose signal in ONLY the exact places you would have before.. but now when your phone would show you as having 1 or 2 bars(on gingerbread) right before you lose all signal, on ICS it shows you as having NO bars because you truly have almost lost the signal. It is VERY accurate, now that I am in an area with bad signal.. I have actually flashed gingerbread again and things did NOT get better, there was just fewer bars that weren't as accurate. But I lost signal in the same spots, and would lost 4g in the same exact spots..

Guys, OP here. This question/workaround is not about getting 4G. I am getting 4G just fine. Its about the phone signal (the bars). My amaze does not get good phone signal in some areas and when I set the network mode to GSM only (2G), phone signal strength and stability increases. and now I want to figure out how I can keep the setting to 4G and get a good phone signal

A new sim card is a good idea.. so is removing the back cover and cleaning off the contacts with a q-tip and some rubbing alcohol. Taking something and SLIGHTLY bending out each of the gold contacts so they make better contact with the case, making sure there is no debris.
Another thing to look into- there is a TON of hacks for cellphone signal that can be done in build.prop.. playing with those settings is probably a good idea.
The last idea- the signal is actually NOT different. The number of bars it shows you is now just more ACCURATE. You still lose signal in ONLY the exact places you would have before.. but now when your phone would show you as having 1 or 2 bars(on gingerbread) right before you lose all signal, on ICS it shows you as having NO bars because you truly have almost lost the signal. It is VERY accurate, now that I am in an area with bad signal.. I have actually flashed gingerbread again and things did NOT get better, there was just fewer bars that weren't as accurate. But I lost signal in the same spots, and would lost 4g in the same exact spots..

Hi SBD, thanks for coming in. I will look into build.prop (ro.ril properties I think) I will also clean any dust inside the phone, may be that will help. The sim card was new when I got my amaze .. but no harm in trying. So I will ask for a new sim card too.
However, in my case, I have a different experience. This is what I did in a weak signal spot.
Have 4G on. I get 0 signal. Can't make a call
go to 2G at the same spot, I get 2-3 bars. I can make a call
I used opensignal app to check signal strength in both cases. with 4G it showed 0. With 2G it showed 42%
Another test. On my route to drop kids off for their day camp, I was on a call (with 4G on) and dropped the call twice (bad reception areas) while going. I switched it to 2G and while coming back did not drop the call.
Before I found this workaround .. people called me and complained that it directly went to voicemail and I never got the call. (no signal). Since I found the workaround, I haven't heard that from anyone.
So I am convinced that there are some real issues in catching the signal with 4G on that get resolved in "2G only" mode. (may be it has to do with the kind of cell towers we have in our area and nothing to do with the phone)
will update if I find more

Yea, it should be lines that have ro.ril that youd eant to change.. and fortunately one of those that you can add(it isn't included by default) will do exactly what you need, default to 2g signal when 4g is too weak. I actually need the same thing, in Jacksonville we have great signal.. except in this new place I moved into. It drains my battery by trying to stay with 4g.. but I don't have time before work to find it.
Look for a tthread by "master&slave" titled something like "super build.prop tweaks" in the vibrant forums, I THINK they had that line.. otherwise google around for something like "build.prop signal tweak" as if it isisn't in that thread, there's a really good one on some other forum.
Also, I remember there being some app that requires root that allows you to toggle between GSM preferred and 2g only.. it changes it at system level, and I don't think it was on the play store, I think it was on Xda.
But yea, I understand your dilemma, and until we get an alternative radio to flash(which I don't forsee), that is the kind of workarounds you need. If you find a reasonable solution make sure to post as it will help me too!

I have had this problem ever since I got my phone in October (right after launch). Updating to ICS didn't help. i've been planning to root and try another ROM, but so far have been skittish as this is my only phone. hasoon, you say it's the SIM card? I am trying the switch to GSM only to see if it makes a difference. My problem is at home - I have terrible service and I live on a mountain with cell phone towers everywhere. My daughter's AT&T and my old AT&T Nokia E71x had excellent service there. I'll let you know if this helps. Maybe a trip to my local t-Mobile store is in order.
It's not the sim card. I noticed on google a lot of people have this problem with htc phones. It's just a bad radio.

[Q] to anyone running 1.17.401.1

I'm trying to decide whether to send my HOX+ back to HTC or not.
Since the 1.17.401.1 OTA update in December I've had assorted mobile signal problems see http://forum.xda-developers.com/showpost.php?p=36221014&postcount=88 which I was certain were s/w problems.
I can now drop the mobile signal (no bars with x) and any connected call every time just by starting the *#*#4636#*#* phone testing menu (if ithe test menu is already running the connection does not drop). This and the fact the signal frequently drops to 1 or 0 bars makes me wonder if there is a h/w fault.
Can anyone else with 1.17 s/w report if their connection drops when they start the test menu?
Any suggestions as to whether waiting for another OTA update or returning it would be the best bet? I've already done several factory resets & installed the RUU twice.

I had intermittent issues like this. Never had permanent issues. Suffering from Wifi disable issue over here upon SIM insert.
I have a signal drop only when typing *#*#4636#*#* and click on phone info. For the rest everything works properly with the latest firmware

You don't get any mobile signal changes when, for example, browsing over wifi?
The reason I've been looking at the test menu output is that I get a consistent signal drop from 3 bars (-91 dBm) down to 1 (-107 dBm) or 0 when using the browser over wifi. I'm not sure if it's the wifi traffic, increased cpu load from idle or something else but it shouldn't affect the mobile signal.

Didn't notice other major issues. e.g. in your other thread, you mention you have a signal drop after coming out of aeroplane mode and getting the 5 bars, I dont have that.

The radio goes totally off around 5 times a day - be it with or without wifi. I also contacted HTC about this and they suggested to wait for the next update (as probably this is a software issues, not hardware...).

I'm pretty sure it's software as the phone was fine before the OTA.
That almost sounds like an admission of a fault by HTC - I don't suppose they gave any timescale for an update?

When you lose your signal does it show no bars, no bars with an X, or require a SIM PIN input?

[Q] Have good LTE signal and apps wont utilize. any ideas?

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.
I am having the same problem i called sprint and they couldn't help at all i think is a phone defect

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

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.

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.
Has anyone found a solution?
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
Sent from my HTCONE using XDA Free mobile app
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.
I agree. I am chatting with HTC Support now.

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.
