[Q] Shows LTE, only works for a few minutes. - Sprint HTC One (M7)

My phone used to work great on LTE, but one day it showed the LTE icon, but I couldn't get it to work. If I toggle airplane mode, then wait for LTE to connect it will work for a few minutes, but then go back to showing the LTE icon but not transferring any data. The phone works fine on cdma only, but I want the strong LTE I used to have. I've been dealing with it for over a month, and other people on sprint with different phones have strong LTE that works fine. I have updated the radio, tried AOSP and sense roms, updated radios, removed and inserted the sim card, flashed an RUU back to completely stock, updated profile and PRL.
On sense roms, I would occasionally get the message "Unable to establish a wireless data connection. LTE: EMM-65535, EHRPD: 65535"
Very frustrating, as 3g speeds in my area are awful, and everyone around me can take advantage of the faster LTE signal. Anyone else having this problem? Is there a solution, or is it a hardware issue?

Do you expericne this everywhere, or just in certain places? Are you "side by side" (i.e. in the same area) with your colleagues who have Sprint when they get LTE and you don't?
After nearly a year of strong LTE at our house, we rarely get LTE now and mostly 3G. This started about three months ago. When it first started, I only had an EVO 4G LTE, but we have also since gotten a One, and both phones behave the same. We live within 500 yards on the west side of the tower, according to SignalCheckPro. In fact, I can go outside and see the tower. When we do get LTE, SCP will sometimes indicate that the phone is connected to a tower futher away. If the phones have been inactive for awhile, they will initially show 4G, but quickly switch to 3G if we try any type network access (i.e. web, email, etc). If we go to the east side of that tower, we get strong LTE and 5-10 Mbps transfer speeds on both phones.
I reported this to Sprint a couple of months ago, and got a response that they were doing another phase of upgrades on that particular tower. I reported it again a couple of weeks ago, but got no response. There is a major retail business street on the east side of the tower, so Sprint may have re-focused the signal on the business corridor. I have also noted a couple of other towers in other areas of the city where I work that have this same highly directional behavior, and unfortnately, the places where I have to be are on the wrong side of the towers.
So, you could very well have a phone hardware issue, but it could also be Sprint. If you check other fourms, you will find similar reports of areas losing LTE after having it for some time. Which is why I asked if you can get LTE in some places, and not others. You might consider getting SignalCheckPro to see where you are in relation to the towers. IMO, Sprint's LTE network seems to be messed up in many places.

Yes, most my friends have sprint Iphone 5c's and a few android LTE Phones and live in my area. they all have strong LTE. I'm pretty sure it is a sim card/hardware issue because my phone has been completely stock and unrooted for about 2 weeks now, and the LTE Only worked for the first day. Unfortunately I got the phone on the day it was launched, so my warranty is gone. Unless there is some trick to get it to stay connected. :crying:

Yes I tried updating those, and updating the radios. Just wondering, when it was new it would always say the sim card was removed when it really wasn't. Is it possible that it has a faulty sim card? I'm pretty sure the sim card is only used for LTE.

I just reset the network to factory settings, I'll try and see if it stays connected tomorrow when I go back into town where it's strong. The sim card has been removed and seems to be clean. I can't be the only one having this problem, can I?

I wasn't able to connect to LTE until I changed my network mode under Settings > Mobile Data to either Automatic or LTE/CDMA. It was defaulted to CDMA Only.

Hmmm..I just exchanged my silver for a black one and also cannot get 4g. My wife has one and hers gets it just fine. My old one did as well. I have checked all the setting suggested above and still nada. Seems this one is going back as well.
I'm on my 2nd HTC one and it operates the same as my 1st one.. In the dock of my car it connects to 4G just fine..with in a few seconds of handling the phone it drops to 3G..It works fine in great signal areas but on the out skirts of an LTE tower it just won't hold 4G..

Im in the same boat. Seems like 4g is HORRIBLE with this phone. Had the Note 2 and wife has GS4 both pick up 4g no problem, but the One picks up 4g for couple seconds then drops off completely. Yes, I tested this in the same areas.
really bummed out cuz I got the phone used so i can't return it. Love the phone, but its useless if i can't get 4g because Sprint's 3g is so slow its unusable.

Well I just exchanged my black and went back to silver and still the same issue. I am starting to think the guy that set up my phone on my account jacked something up. I have been all through the service provisioning matching it to my friend that has one....and only found one difference. Seems my phone is only picking up CDMA-EVDO Rev-a instead of CDMA - eHRPD. When I change the prefered network from LTE/CDMA it will try to connect to eHRPD but then switches back to EVDO and no 4G. So I will try to call sprint and have them inspect my account as I have not seen a way in the service programming to force eHRPD. It would be nice to have the others that are having this issue check the Mobile network type as well and see what they are running.
Try not touching the phone and see that it holds 4G until you touch it...I know its pretty useless to not be able to touch your phone but this has been my experience.
In my experience, not touching the phone does not seem to fix the problem. I do notice a small signal loss if I have the left side of the phone against the palm of my hand. The real issue here seems to be related to the phone having some sort of broken threshold from when to switch to 3g to 4g and how much better the 3g signal has to be in order to decide to switch off of 4g to 3g.
I noticed that the LTE Scan Time is set way higher than what the EVO LTE is set to with latest firmware (300 on the HTC One vs 5 on the EVO LTE). I have not had much time to test changing this to see if it makes a real difference or not though. You can check what your LTE scan time is set to in ##3282#. You will need to get your MSL to change it if you want to do that (there is a method to get your MSL without rooting here on XDA).
Another thing you can try to see if it is indeed a reception problem or a problem with the phone not switching between 3G and 4G smartly is to set the phone to LTE / CDMA(1xRTT) only. You can do this in *#*#4636#*#* under the phone information submenu. Tap where it says "CDMA + LTE/EvDo auto" and change it to "LTE, CDMA" or even "LTE only".

Issue resolved for me! After 6 phone exchanges I was able to uncover what was causing the phone to not get on eHRPD which is Sprints upgraded software on the towers. I called sprint support and made them verify my UICC ID under about/phone identity, this also is the same as number as the SIM id. They did not match what was on my account. I went back to Best Buy and they called activation's and they sent a profile update with the correct SIM and UICC ID and it solved the issue. No more 104 data issues and I can get 4G now. WOO HOO!
I do want to say that Sprint really went to bat for me to get this resolved. I have to say thanks to the San Diego Sprint rep who kept in touch with me through out all of this.....Thank you man!!!

You have to call sprint customer care to have them verify what you have on your phone. I recommend calling from some other phone when you call though. Just explain that you are having issues with your data and you heard that sometimes the UUIC ID/SIM ID are incorrect. They might come back and tell you, "well thats for international only" but in fact the SIM ID is used for LTE from what I found out. Just insist (nicely) that you just want to try it.
On the phone you can see your SIM ID under settings/about/Phone Identity.
One way to see if this fixes the issue is look under settings/about/Network and look under Mobil Network Type. If it is always running in EvDo rev A. then you have the issue if the towers in your area have Network Vision updated towers.
Hope this helps...PM me if you want more information. I can also get you tower data in your area if you would like.
slayer69, Thank you so much for your quick response. My phone runs with EHRPD when it showed 3G, not rev. A. However, my phone had the same issue, not connecting to 4G/LTE. From time to time, it will show 4G signal on the bar. However, when I tried to use it, it will switch back to 3G. I will call sprint to verify if tI have the sim card issue.

I talked with Sprint. It seemed that my SIM/UICC code is matched with the system. So my problem is still not resolved. I used an app to check the signal information, which showed that I have -70dB LTE signal. However, I just can't connect to LTE.
It seems that it is not only me. Check this link

Thanks to all in this thread. I had the same problem while in Oakland. My wife has an S2 on sprint and she had a strong 4g connection and mine was stuck on 3g. Now if this is a hardware issue that this phone has what if anything can we do. Can we exchange for a different device

HALP! Signal problem or defective phone?

I'm not very familiar with this. I've have data (4g lte) connection issues for a while now with my m8.so much so that I'm considering going back to Capts fastboot recovery file just to wipe everything and start over. I'm constantly in a 4G area, but can't get it unless I switch to airplane mode and back. Even then it's short-lived in multiple known 4g areas.
Anyway, tried updating prl. Get an error 1012. But when connected to my airave no problem. Just wondering if that's good to update while hooked up to airave cause I can't in a data area.
Thanks
Don't forget the thanks button!
Ok no one has said anything lol
I've been reading and trying to research my problem. I thought I saw a thread on this same issue but haven't found it yet (hard juggling wife kids work & Android).
Anyway I've spoke with sprint and I just don't trust them.
Been watching my signal on net monitor and everytime I connect to am ehrpd tower my phone tries to connect to lte but apparently didn't want to and jumps down to 3g. I can get lte but has to be a lte tower. Not real knowledgeable yet in this stuff but I'm trying.
Currently on Viper
Firmware 1.54.401.5
Prl 51100

I'm having similar symptoms. I upgraded this past Monday from a Samsung S3 that had good LTE and CDMA voice inside my home (Plano, TX) and my new M8 cannot maintain any stable connection on the voice or data sides. Even at my workplace, I can only get a weak LTE/Spark connection and no voice. I've already worked with several techs and support people at Sprint throughout the week and even exchanged to another new M8 with no better success. I believe it has to do with the Spark (which is actually one of the LTE-Advanced features) and the CSFB (Circuit-Switched Fall Back) that allows us voice on the old CDMA network until VoLTE to rolled out. I am frustrated enough to turn it back in and just go back to using my old S3.

I have no problem with the voice. This is where it seems many are having problems. I'm trying to figure out if this phone is supposed to behave this way with ehrpd towers.
Don't forget the thanks button!
I've mentioned in a different thread that LTE for me is mostly stable, but it does get a little wonky on me. For example, one day at work the LTE will be strong and solid and the following day it drops out intermittently and toggles 3g on.
Probably a sprint issue, not an m8 issue
I had the same prob with my first M8. Could not got 4g until I switched airplane mode off/on. Took it back withing 14 days and got a new one. This one gets 4g/LTE now but have had to switch airplane mode a couple times. Also, my airave does not like this phone. Sometimes it will give it full signal and then other times 4g will be showing and I have no signal and miss calls. I called airave support and the solution they gave me was to switch to cdma when at home.
This is a known issue with the M8. Some people have had success with HTC replacing the defective phone. http://forums.androidcentral.com/htc-one-m8/390449-sprint-signal-issues.html
Yep, defective phone
I had terrible connection problems after buying a brand new phone! Ex: No service, Dropped calls every minute, No LTE, 3G was rare. Basically it was not even a phone! I had to ship mine back to HTC. This was after hours at the Sprint store, and many customer service chats with HTC reps. I also had to unroot my phone which was a huge hassle considering I just found out how to root it. After getting a new one, works fine.
Don't let them tell you it is a service problem if you are having the same symptoms. THIS IS A HARDWARE PROBLEM and HTC needs to fix your phone. Hope this helps

No data or voice, shows ! in icon

This last week at work I started noticing that my data and voice would drop off and I would get the icon showing half signal but would have an ! In the icon. When I look at the Sim status it shows I'm connected but I'm not. After rebooting the phone I will have 4G service for about 20 minutes then it drops off again.
I have Tmo and contacted support and they told me to reset the APN but that didn't help.
The only thing that looks new on my phone is a recent app called Google Connectivity Service.
Other people at work on Tmo are not experiencing this issue but they are on Kit Kat still. I don't have this issue at home, I get full LTE there.
EDIT:
This is still broken as of 05/20/2015 -- Possible workarounds can be found here (thanks TaintedByte).
I have this same issue but it's only at home. I think it's just due to poor service when I'm in my house or I have to many towers to connect to..... It switches from no data to E,3g,H,H+ constantly while I'm just sitting on the couch. But I also get ! Frequently
I would think it was poor reception but this a recent thing for me. Before this week I haven't had this issue and others in my office have full 4G signals.
OMG. I have the EXACT same problem. I just switched to TMobile and got the nexus 6 on the 13th. Everything was "fine" at my work. I'd be stuck on 3G most of the time, but it never failed me. Then starting this week, it's been dropping signal like crazy, getting the !. It's defintely due to a weak signal, but I don't know why it was fine for 3 weeks, and then all of a sudden started having problems.
+1 - on Spring Rom
EDIT - Went back to a backup of Bliss, problem has not appeared.
I was trying to fix it by forcing it to 3G, but my phone likes to try to switch to HSPA when I set it to 3G and that one is pretty weak too. If there was a way to force it to 3g without hspa, I think i'd be fine. I just tried forcing it to 2G and I get a pretty strong EDGE signal. It'll be slow as balls, but I'll see if that fixes it. Unfortunately the area I live in isn't going to get band 12 for quite a while, if ever. It's one of those major cities that have an exception on it for a TV station that still exists.

3G is HSPA/+. On Tmo anyway. When in 3G mode it will display 3G (also known as UMTS) when data is idle and will display HSPA or HSPA+ when data is active.

Well that's weird, because sometimes I'll see 3G shown while data is active and I see differnet levels for 3G vs H on the icon. But it looks like I have a pretty strong H right now. Maybe I'll have good luck this afternoon.

I take it back. Sometimes the icon will get "stuck" and show a great signal but no connection.
Have you guys tried turning off enhanced LTE in carrier settings?

I just did. And eventually it died. It seems like if I leave it on the preference of LTE, then I get the exclamation point. If I force it to be 3g only, then I get the situation where the icon claims it's 3G, and the signal looks good, but I have no service.

Did it just start, or have you been having it for a while? Has anyone tried using the radio image from 5.0?

Just since 5.1 I believe, at least didn't notice it before...
Been having signal issues as well lately (T-Mobile) and now that I think of it it's very closely timed to when that Google Connectivity app showed up! Just disabled it to see if I notice a difference

I've disable mine and so far so good... but who knows. What version do you have? I see I have A.1.0.1, but on the play store I see an update for B.1.3.3. It doens't show up in my list of apps to update, but if I do a direct search, it shows up as an update.

Of course I had to just go and jinx it. It just got the problem again. But I did also reenable the app for a short while before disabling it again. Maybe it's related...

Not sure if the version I was running assume that it was the latest, but it uninstalls updates before disabling ...
Seems like the affected users are on T-Mo. Have you gents considered tower maintenance/upgrades?
I'm on T-Mo as well. I've had a few similar instances over the last few months, but the problem resolves in the areas it's happened, and now the reception is better.

For a whole week? It's defintely a signal strength issue, I just can't figure out why. The way the building I work in is laid out, there is a hallway along the edge, and I get great LTE there. then I walk into the room a few feet away from the window, and it's fine. Then I go behind my cube wall, and it starts to get weaker. Than as I move a few feet away from the wall, it drops to 3G.
Also, it looks like disabling Google Connectivity Services didn't do it for me. I had rebooted with it disabled and evenutally it still died.
rbox said:
Well that's weird, because sometimes I'll see 3G shown while data is active and I see differnet levels for 3G vs H on the icon. But it looks like I have a pretty strong H right now. Maybe I'll have good luck this afternoon.

I take it back. Sometimes the icon will get "stuck" and show a great signal but no connection.

Very odd. I've been having some weak LTE signal issues at home, but only at home. Wife's S6 stays connected to LTE -110dbm here while my N6 hunts and switches back and forth between 3G and LTE. Started happening about 2-3 weeks ago. I've been hoping it's T-Mobile, not my phone

It just started this week for me. I've had 5.1 for over a month and haven't had this issue before Monday.
I've tried disabling the Google Connectivity Services (v B.1.3.3) app and that did nothing for me as well. I also switch my APN to IPv4/IPv6, it was on IPv6 only but it didn't make a difference. I also did a test by taking the phone to a location that I know has strong LTE while it have the ! icon and it would not reconnect to any network. I tried toggling airplane mode but it didn't refresh the cell/data radio either. After rebooting I had full LTE service.
I talked to Tmo reps and they didn't see any maintenance on the towers in my area but they opened a ticket for me.
It seems like something is bugging out while it jumps between LTE/4G/3G and then the radio crashes. At home it's solid LTE and I don't have any issues.

CDMA-Less Device on Verizon (Amazing!)

One of the great things about this device on Verizon's network is instant LTE service. In my house I have dead areas which cause my signal to drop. When trying to get LTE back it can sometimes take 30 seconds or more because once I get to an area with service it will first go to 3G and then sometimes get stuck on it and I'll have to toggle airplane mode to get LTE back in a timely manner. With the OnePlus6T as soon as I have service it goes instantly to LTE! This is the first time I've ever had a device connect to LTE so fast. All my previous devices over the past 5 years since I've had LTE in my area have annoyed me because they always go to 3G first even though I have strong LTE service where I live.
I've always wondered why companies can't make their phones instantly connect to LTE when it's there and why they always favor 3G -- but this is no longer an issue since the OP6T doesn't have 3G on Verizon

What now happens in the areas where you only had 3G on your old phone? On your new Oneplus 6T do you just have no signal at all since it is only a LTE phone?

Well, I'm assuming that in none LTE areas I'll have no signal at all. But, Verizon's whole network has been converted to LTE as far as I know. I never go anyone where I don't have LTE (and I live in the sticks). But in the off chance that happens I have 2 lines and my Pixel 2XL is still in service.

I too am on Verizon, and in my office at work, one of the places I had zero service on Axon 7, I still get calls and text and one spotty bar of LTE. At my house, in the basement bedroom where I have missed countless calls and txts, I have 3 bars of signal and no issues with calls, txts, or LTE.
I drive all around my county for work, and so far, I havent hit a no service area. on the Axon 7, they were evident. It could just be better coverage due to glass back vs metal (the real reason OEMs have switched to glass back imho) or the better modem of the SD 845, but hands down, the cdma-less VZW is far superior for me IRL usage so far.
This is obviously subjective, but despite living in a rural area, I have no need for cdma so far. Vzw is the only carrier with good coverage where i live (upstate SC) and somehow, cdma-less is better.

LTE only in *#*#4636#*#*
2g/3g/4g in Preferred Network Type
Yeah I was in a spot Friday that goes to 3g or no signal often. I still had some sort of signal. It had an R and an H on the signal bar I believe. It worked fine and was still pretty fast online. Signal is way better than any of the Pixels was.
When I select LTE only I get two signal icons in the status bar.
Just curious will wifi calling / VOLTE work on Verizon?

Volte has worked for me since the moment the tech I chatted with switched my sim to CDMA-less. Case and point, I am in the section of my house with the worst reception, a spot where the Axon 7 I came from got zero service on tmob and Verizon. Yet, much to my heart's content, I have service and VOLTE in the downstairs Faraday cage that is my house.
To the second part, no, Verizon doesn't support wifi calling on this device yet. Hopefully, they will work that out soon, but so far, I am having the best network experience I have had yet with Verizon.

Wow, just reset mine and noticed. I guess I had defaulted back to LTE/CDMA/UMTS, which apparently works fine. When I switched to LTE only, you are correct, double LTE icons in the status bar. I don't remember it doing that on 9.0.4. That being said, the other, default setting works perfectly fine for me.
Did y'all not have any problems sending/receiving MMS (not SMS) when your phone was in LTE only mode? I had to manually switch back to the default preferred network type from the dialer menu in order to fix that issue.
I had no problems at all I did the following.
1.Ordered new SIM card
2.Turned off old phone and took out SIM from old phone
3.Went on my Verizon account put in info on BYOD
4. Insert New SIM in 6T
Finish Setting up in your Verizon account then turn on the 6T
Done all working
I was worried because my old phone was 3G but the LTE is everywhere I always have signal.

S10 4G bug?

has anyone noticed that the 4G on the S10 is quite buggy?
the speeds are extremely unstable, and sometimes completely unusable. (not a problem with the carrier, tried it on another phone and it's fine)
What I've noticed is that if it ever goes into medium power saving, 4G will stop working completely, it'll still show 4G, and i can still make calls, but no internet connection, even after exiting power saving mode. The only fix is I'd have to restart the phone for 4G to work again.
anyone have the same problem/ knows a fix?
I've read that I should do a factory reset, but I really want to avoid that, setting up the phone is time consuming.
Side note: battery life is not as good as expected, but that seems to be an issue for all exynos, not just me.
Same Problem here i unlock phone 4G shows but it tanke some time if i can use the Internet
Speed is Very slow and unstable
I am having connectivity problems as well. Keeps loosing the connection. I have to turn on airplane mode then turn it off all the time.
I don't have any problems with network connectivity, so far. In the link my result a moment ago: https://www.speedtest.net/my-result/a/4796337263
Hope you get some sensible connectivity soon. Cheers!
Same issue here! It was fine since I first received the device, but yesterday, I manually changed the network toggle to get better indoor signal. However, even after setting the toggle back to the original setting the LTE and data service kept dropping out. I tried manually toggling, switching network bands, etc... but nothing worked. It just keeps dropping data service.
I just hard reset the phone moments ago, and will update accordingly!
Update - Even after a network reset and hard reset it still dropped to Edge data a few times. However, after the last hour or so, it has locked back on to LTE+ and is holding strong. Seriously hope this is a software bug and not a bum radio chipset or antenna.

I'm on tmobile and my data is horrible in certain and what's weird I have all bars.

not sure if i should say that its good to know I didn't get a dud.
but man, samsung needs to get their sh*t together, this is not acceptable for a flagship phone.
looks like i'll have to do a factory reset soon.
I'm on tmo as well. I have a feeling it's just jacked up radio software. I did some more tweaking and went into band settings *#BAND# on the dialer and disabled all the LTE bands that aren't used by TMO and that seems to have helped as well. It think this issue is congruent to the known issue with Sprint devices trying to connect to incorrect bands. I haven't used it out and about yet, but it definitely helped my phone stay latched on to LTE from my home. Additionally, when it does drop to HSPA, it doesn't get stuck like it used to.
I recommend tweaking the band setting before doing a hard reset.
Update - still doesn't fix the problem. Pains me to say it, but I'm afraid I have a hardware issue. I'm going to try a sim card swap as a last ditch effort, but will also seek an exchange as well just to get ahead of the problem.

This shortcut only works on Snapdragon version, do you have Snapdragon with 4G issue?
This code only runs on the Qualcomm chipset version. Oddly enough, my friend with the Exynos version has no problems, even though he's missing a couple of TMO bands for the US.
Yeah I have Exynos S10+ as well and it runs fine on T-mobile USA

This code is not working on SM-G9730 Qualcomm Hong Kong version. Any ideas?
Same problem here. I got the snapdragon US unlocked variant using here in Spain and compared with my old Google pixel, they do not have the same speed LTE connectivity even using the same SIM card. I tried to force using the 20 BAND (800 MHz) but I dont really know how. My galaxy s10 plus is using the BAND 3 so it does not let it picking the fastest possible band in my city. Any ideas? I also did think galaxy s10 plus US variant did not have 20 LTE band, but I checked it and realize it even does. One more question, what is the difference between 4G and LTE? Here in Spain all devices are running 4G, not seen any device running LTE, but my new samsung does. How can I switch it to 4g or LTE+? Thank you everyone boys.
just wondering if anyone has gotten the ASCA/ASC8 update and can report whether this problem is solved wit firmware update?
Bands matter depending on where you are. Depending on your area, only specific bands will be used. However, some bands used, while not faulty, are easily interfered for some reason with cases or other obstructions like your hand. Most likely, Samsung is planning to give a large update considering signal direction. I would probably not factory reset if you have a lot of data, and the problem would probably come back.
I ended up having to send my device in to Samsung for analysis and repair. I'll keep everyone updated.
after ASC8 update, i think the problem has been solved, havent noticed any problems so far
