[Q] No 1x when 3G not available - Sprint HTC EVO 4G LTE

Sorry if this has been asked before, I could not find it anywhere...
With my Evo LTE, if I have no 3G signal, I get no data at all (not using wifi). Is there supposed to be 1x data? With my Epic, I would bounce between 3G and 1x while at work, getting about 60 Kbps (horrible I know, but at least it worked). Now with my Evo, I either get 3G or nothing. Most of the time I get an error that there is no network connectivity, where with my Epic I never got that, it just worked slower at times.
So, is it a configuration issue, does the Evo not support 1x, or could I possibly have a hardware issue? I have domestic data and voice checked.

Well, this EVO does not want you to know whether you are connected with 1x vs 3g. So, on stock it will ALWAYS show as 3g. This is why you are going from 3g to no connection whatsoever.
If you are rooted, install a custom ROM as they all have the option of including this modification. If you would like to keep your current set-up, there is a thread to walk you through the necessary changes.

On a side note, the EVO also gets horrible reception in general. So although you will have a better idea of what your connection is, the fact of the matter is that your reception is probably not as good as it was with a previous phone.

Well, at least it makes me feel better knowing that it isn't a hardware issue. My voice reception seems better with this phone than my Epic, but data, not so much. Maybe LTE will magically fix all my issues? Other than a dead pixel, screen being a little washed out compared to SAMOLED, and reception issues, I still like my phone. Not sure if the SGIII would have better data reception where I'm at. Sucks that I have unlimited data, but just can't get at it.

I'm not convinced.
the first day our two after I got my phone, I had the same problem.
I tried changing from CDMA & LTE to CDMA only. That didn't help.
I then rebooted my phone. After that, data seems to work fine. My display sometimes shows bars with 3G, and sometimes simply bars only.
Before I rebooted, it never showed 3G.
I had even started a thread about it. But it seems to work fine now.

Drove Around Today and Did Some Tests

Have been having issues here in NE MA with horrible 3g, GPS dropping too often and a bad phone signal to the point of not being able to make or receive calls in areas that are marginal...but areas where my EVO always showed 2 bars and worked fine.
In what I would call "strong" signal areas, still had GPS and 3G issues no matter what. What I found with the phone signal is that in these areas, mit works fine, although it fluctuates every few seconds from a full set of bars, to 2 or 0 and then jumps back up again....constantly.
In the "marginal signal" areas where my EVO 4G worked fine and always showed 2 bars, the 3D shows none and won't make or receive a call. What is most perplexing is that even though it is set to "automatic" on the networks, it is not roaming to Verizon...and my buddy taking the ride with me had a full boat signal on his Verizon phone.
I was totally unable to get on the internet in these areas, although I could still send a text.
I don't get it???
Sprint re-provisioned the phone twice, and today a service center wiped and reloaded everything and also claims to have installed a "fifth update" which my phone never got.
My tests were done post upgrade and it did NOTHING to fix these issues.
With your fifth update did you check to see if you had S-OFF? lol
I just sent a reply back to HTC regarding Bluetooth and Roaming data issues and GPS issues... I await their response... However, I may be returning it and going to some other device.
I've found my old Evo3D, and the exchanged one to show 0 bars in places the Evo4G showed 2-3 bars. For the first time in my life, thanks to the Evo3D, I've had a dropped call, and it was in a place the Evo4G gets 2 bars and perfect voice.
Yeah, today at work I missed 3 calls and couldn't read XDA in the bathroom. That was the final straw. I reactivated my 4G, did some tests...and...well...the 3D has gone back home. Perhaps just for now. The 3G radio on that thing sucks. Maybe a radio update will fix it, but I'm not so sure.
Since I'm impatient and have kinda decided to go the Nexus rout from now on I stopped by the sprint store afterwards and did some signal tests with the NexusS4G--which has known 3G reception issues. Well, it had identical bars...that was a good sign, so I dug in a little deeper and it had nearly identical reception as my E4G.
The .3" of screen size will be missed, and it'll be hard to get used to the light weight...but I think tomorrow I'm gunna buy it. Sure, no SD slot, but, 16gb should be pretty damned good...I never did replace my 8gb card, though I did bump the limit a lot. I'm also sure the camera is way better...
...or I'll just wait for the SGS2. I'm not so antsy to get a new phone now after anticipating one so hard and being mostly disappointed. It's funny, the one thing I was the most critical of beforehand ended up being the only thing I'll really miss...the 3D. Lol to that.
Unfortunately I did a stupid thing and traded my EVO 4G in when I "upgraded" to the 3D.
I tried to get Sprint to do a swap....take back the 3D, take away the $150 trade in credit and give me a new or used EVO 4G for the time being and they absolutely refuse to do it without using up my upgrade to get back what I traded in.
Looks like will deal with this phone and return it on day 29, activate my BB Tour (YUCK) and live with that till something reliable comes out hopefully at the end of July or more likely in August.
This sucks.
I am having nearly similar issues. I am dropping calls in area's that have 4-5 bars. I look and when it reconnects it will be down to 0 signal and then back up 4-6 bars. Really odd.
Sad thing is I am coming from ATT and I only have till early next week to decide to stay with sprint or not.
Ohh decisions... not fun and not a good sprint evaluation.
Yeah, I really hope this is something that they can tweak with a radio update. My old Hero got a lot better reception than my Evo 3D.

I can assure you it is not Sprint...it's the phone. I had the same/similar with my 3D...but never with the 4G.
Download Open Signal Maps. It will show you what tower you're connected to. I noticed something similar with my phone (the signal bars fluctuating). I checked Open Signal and lo-and-behold, my phone was tower jumping between 5 different towers in my area... I didn't even know I had 5 different towers in my area.
Ideally, your phone should lock on to the strongest signal in your area and not jump from strong signal to weak signal to slightly-less-weak signal, to strong again... Also, check out this thread:
http://androidforums.com/htc-evo-3d/361044-official-solution-3g-issues-3d.html
This problem doesn't affect everybody. For instance, my brother got a 3d the same day I did, and he's consistently getting 500-700 kbs d/l in the same places I'm getting 11 kbs d/l.

Do ##786# (or 768, not sure). Then click menu key and due a reset. This will also factory reset your device unfortunately. But I was having eh same problems, getting horrid 3gs speeds of around 50 kps. Once I did this my evo3d is constantly getting better 3g speeds than the 4 other evos in my family.
For some reason a lot of the evo 3d did not get the data set up right on one end or another. This seems to fix it.
Looking at that link now. Yes I've had open signal maps installed and I too have noticed that I am jumping between towers "a lot" say every 10-15 seconds or so. And that can be just sitting still in a parking lot and dropping calls :-( Will take a look and glad to hear that it is more with the phone than the actual network. I may have to downgrade to the 4G or NS4G.

Anybody confirm that this works? My girlfriend's 3D gets a lot worse signal than mine. I'd definitely try this but only if it might actually work. She really doesn't like the factory resets because she has to redo all of her preferences.
Her's is so much more worse than mine that we've been thinking about getting it replaced.

##786# will do a factory reset on your phone. ##72786# will do a "Data Only" reset (i.e. you don't lose any installed apps). I would try that before ##786#. You will need your MSL for both. I have done both. Unfortunately, in my case, the 3g improved for only a couple of hours and then it went back to tower jumping both times. I now have an appointment with the sprint store to replace my 3d later this evening.

#786## worked to fix my 3G speeds. I was consistently getting under 100 Kbps up and down before walking through this procedure with Sprint a week ago. Since then, latency has gone down and speeds have improved significantly.
It did not fix persistent problems with GPS not locking and having poor signal reception compared to the 4G. Between these issues, overheating and the locked bootloader, I am pretty close to returning this phone (although I like most other aspects of it).
Looks as though the Photon 4G cleared the FCC today.
I think I will live with the 3d a bit longer just in case they come out with some miraculous software fix, otherwise return it, activate the BB until the Photon comes out.
Hopefully, for where I live and work at least it will have much better reception.
That's strange that a few of you guys have had every issue that was reported in some of those awful reviews. I've actually found my 3D has the exact same signal as the 4G sitting right next to it. It also recognizes changes in signal faster than the 4G. I must have been lucky to get one with no issues.
My EVO 3d is straight out of a snoop dog song, my calls are droppin like their hot!
My 4G never did this crap!

I don't believe that there is anything wrong with the phone itself, however I do believe that there was a bad batch of radios installed on some of the 3vo's. Like I said, my brother's 3vo is working just fine while mine seems to be a lemon.

losing data when data switches between LTE and 3G

I've been having this problem probably once a day since I've gotten the phone where my phone will lose data signal while switching between 3G and LTE and the only way to get data back is to restart the phone. Turning airplane mode on and off won't work either.
Ive had that issue too..but most of the time it switches back n forth no problem

why should bugs in the LTE system affect 3G?
the 3G our phones use is not exactly the same as standard 3G unless you force your phone into EVDO 3G via the ##778 menu. which if you are not in a 4g zone I would recommend simply for stability. The 3G our phones use is basically a layer between 3G and LTE as I've had it explained to me.. I really don't know much else about it though, sorry. I'm sure someone else here can shine more light on it however.

same here guys. call Verizon and let them know. I think it helps if a bunch of us make them aware.
I've had a ton of weird data issues with the Rezound. I get 1x where i should get 3g, i get 3g where i should get 4g and i get nothing way too often.
I've only had this happen once with the rezound. Shows nothing but bars, no data can be used. Sometimes switching to 3g or 4g in lte on/off helps.
Had this problem intermittently on both my wife's and my bolts, completely agree its just a lte being a new tech issue.
I've listened to a podcast on how the handoff works and its definitely not fool proof.

phone will reboot and you should get 3G back
This changes your network from eHRPD back to EVDO Rev.A. For LTE phone owners, eHRPD causes 3G to die (most of the time anyway) when the LTE network has problems. Get back on normal EVDO and you're good to go.
^ from Jntdroid on another forum (not sure if we're allowed to post to other forums here) I'm not positive on where he got it from, but this is a capability of all HTC 4G phones
I've had occasional issues with being down to 1X, but even that was only during nationwide 4G network issues, definitely get in touch with VZW about that... not that they have enough sense to fix anything *sigh*
Data Connection slow to Acquire (3G/LTE)
If I'm on the subway, or somewhere with no service, then come above ground, I get voice (full bars) but no data -- it could take upwards of 3 minutes+ for data to come back up. Any thoughts?
I've been losing my 3G service throughout my city, being restricted to 1x so many times lately where I SHOULD be getting 3G!(4G isnt available in my area yet). It's really annoying...perhaps nexus isnt theeee only one...
^should I try calling and programing what the user implied? Again, I am not in a 4G area...

Same issue as you. I live in a 3G area only and my 3G drops out a lot. Even a reboot doesn't get it back. Not sure what to do :/

Anyone have an issue with 3G?

At first I thought maybe my area just had issues with the towers, I've only had the phone for about a month, but my data will regularly drop to 1X, and even on 3G, I will often get really low speeds.
I'm beginning to think my phone might be defective because with the EVO4G prior to it, I would get solid data for the most part all around town, and yet everyone says the MoPho's radios are better than the EVO and most other Sprint phones.
I feel like I've tried almost everything.Turning on airplane mode and re-using data doesn't seem to help. Rebooting doesn't help. Switching from home to automatic or vice versa doesn't help. Removing Sprint proxies didn't help. Using the different settings in the V6 3G script didn't help.
I don't always have bad speeds though, sometimes I've gotten up to 1.4 mbs (good for my area), I just seem to have a lot of drops and very inconsistent speeds for the most part.
I've been using CM7 but going back to Stock doesn't help. I'm using SBF 198.6 which I updated to from the phone itself. Would flashing SBF 198.7 perhaps help?
Anyone have any other suggestions? Thanks in advance.
I doubt the phone would be defective! I think you may need to flash back to stock to test a little more. When you do, go to mobile networks and set it to automatic instead of cdma only see if that helps. I stay in a ****ty service area and I haven't seen a 1x since I've owned my photon (best radio in any phone ive owned). My GF has an epic touch 4G if I unplug the airave her phone will go to 1x and mine will not. I'm willing to bet sprint's towers are just jacked up in your area...

[Q] Data connections being weird

First of all, I live in a suburb of Dallas which is completely covered in LTE according to Sprint's coverage map and I can affirm this by Sensorly and my own personal usage of my phone when I see 4G LTE in many places. However, lately I have noticed on the bottom floor of my house I usually get 1X or 3G, whereas upstairs I get 4G quite nicely. In other houses nearby (less than 1 mile), my phone doesn't even get data many times (and if it does, it is 1X) whereas other Sprint iPhone 5's are enjoying LTE in the same location.
Now I know our phone's have connection issues, but why am I not even getting 3G? Is there anyway to help force my phone to try and get more 4G signal because I know for a fact Dallas has pretty decent 4G coverage? When my phone goes into 1X it also seems to be sucking up quite a bit of battery. Any help is appreciated!
I am running MeanBean 3.09, S-ON, with the newest Bulletproof Kernel.

MeanBean has the Roam only option baked in, just go to settings - mobile network and set it up... The battery drain is "normal" when the phone doesn't have a good signal... Roam or use wifi... I know it doesn't make sense but that's the now network...

What is going on with Sprint Service

As some of you have probably read.
I gave up on the M9, mostly prompted by dropped calls, or calls going straight to voice mail.
I had the M9 replaced and gave it to my wife. It's been near perfect for her, she even dunked it and it's still running great.
My G4 is now doing the SAME thing. Although it has not dropped many calls, tons of calls go straight to voice mail.
Had a very important call this morning and even shutoff LTE, WIFI and Bluetooth and only had 3G on. And it went to voice mail.
The signal is not great, but should be fine for CDMA. Previous generation phones were fine (M8,M7, etc.)
I do see the signal bounce. Where it will be 3-4 bars one minute and none the next. The bouncing can be common in weak LTE (which is definitely weak).
But it's even bouncing with LTE off.
Even at home with two phones in the same location.
My wifes M9 will work, but my G4 will go to voice mail.
Where a couple months ago at home
My wifes M8 will work, but my M9 will go to voice mail.
Could their be something on the account that limits my phones? Like wrong bands or something. Not enabled for Spark but on a Spark Network.
As soon as Verizon gets the LG V10, I'm 99% sure I'm gonna switch. Don't know what else to do.
I don't really care for how locked down Verizon is, but I need a working phone.
This problem happens at multiple locations.
Any ideas appreciated.
I know this isn't specifically an M9 issue, but I know their are more experienced folks around here that might know something.
It is related to M9 TYPE phones though (Spark Generation 2-ish phones). It started when I switched from M8 to M9.
Upgrading my wife from M7 to M8 went fine and from M8 to M9 went fine.
Upgrading me from M8 to M9 went south and from M9 to G4 went south.
All SIM cards cam with respective phones.
All bought new.
All S-Off and/or rooted.
I may have found the answer. Read this !! It has to do with having WIFI on and phone going to sleep. Which is exactly what happens on G4 and M9.

I disagree...I'm using the opposite settings that he is saying to use & I've never had this issue (that I know of). I don't make alot of outgoing calls...most are incoming...I also have my work cell fwd'd to my M9 so I don't have to carry 2 devices...I'm on Wifi a majority of the time, I get calls & texts all the time w/ no issues...the only thing I have checked in Advanced WiFi is Wifi Optimization, Keep Wifi on during sleep set to always
Fix
------
The fix is to not have Wifi on when the phone is idle/sleep. change your Wifi settings below to the screenshot below.
Settings -- > Wifi -- > MORE -- > Advanced -- > "Keep Wi-Fi on during Sleep = Never"
I also have "Network notification" and "Always allow scanning" enabled.

Sprint did (in my opinion) a very poor job with how it handles calls. One of my favorite phones was the evo LTE which not only could do LTE and a call at the same time but if you weren't in 4G it could do SV-DO and work on 3G which it actually worked very well. Especially at the time when I had that phone, I hardly had 4G anywhere so being able to use data at the same time on 3G was great.
That said, that feature didn't stick around long. The m7 had a separate radio for LTE & 1X meaning you could surf at the same time because it had separate radios. This couldn't do 3G which was a step backwards however 4G was becoming more mature.
Fast forward to today and with your modern tri-band device while it supports multiple bands that the previous phones didn't, most people have no idea what that means they usually assuming if it's a 4G phone well then it's just that how is any different.
I have had plenty of people complain to me about calls going straight to voicemail or signal issues. Rather than having separate radios, Sprint just uses CSFB Circuit Switched fallback so when a call comes in, it lets the phone know via LTE and immediately switches back to 1X to grab the call. That said it's by no means perfect especially in a bad signal LTE area can cause issues. When I'm at home or work I usually set my phone to CDMA only since I have wi-fi there is no advantage to be on LTE, causes issues with calls coming through and wastes battery. Most users have no idea about what is actually going on so it's hard to explain to a friend why when a caller calls them, the caller might here 5-6 rings before the phone even goes off. Sprint's LTE signal frankly sucks in most places I go, even right next to the tower sometimes you won't get full signal.
Anyway if your wifes phone works fine in the same spot as your G and you are doing all your testing off of LTE and still having issues that tells me either you have a bad radio again or something is provisioned wrong. I would put the phone back to stock, reset the radio and reactive the phone then do some testing with calls off LTE again. If you still have issues at the point, I would swap the phone. My M9 is pretty good with CSFB, I haven't had too many issues with it but really I think it's a very poor solution how it works especially when your in a fridge LTE area with the phone bouncing in and out of LTE.
Once the network goes all LTE (god knows how long that will take) I think this will be a thing of the past but for now CSFB now it's here to stay. I don't see Sprint ever going back to separate radios like the previous gen phones as they would more likely be focused on voice over LTE instead.

I think this may have started the same time MMS started failing for SOME folks if WIFI was enabled. Disabling IPV6 on WIFI was a work around (which is disabled on your ROM).
But not everyone had this issue and depended on their router.
So their is weird sh$t happening due to Android changes.
I think this issue is related and not everyone runs into it.
I have had WIFI Calling setup, but disabled it on both M9 and G4 (because it's extremely unstable on every phone I've tried).
Not sure if that is part of it. Like my account knows it's WIFI Calling capable. But my wifes never had WIFI Calling setup, she also does not run WIFI at work. She's never had the problem (even with the same phone I had problems with).
Again I don't know the exact details, and this is not a fix. But disabling WIFI when asleep seems to have stopped it problem. But I need to go a bit longer to be 100% sure.
I've seen similar threads on many phones and carriers and many start off saying "Problem started with 5.x.x OTA update".
I think I was close when I thought it was the optimizer. And before I found that thread, I was testing with WIFI completely off (which also worked).
Something is a miss and there may be more "options" to cause the issue.

Sprint did (in my opinion) a very poor job with how it handles calls. One of my favorite phones was the evo LTE which not only could do LTE and a call at the same time but if you weren't in 4G it could do SV-DO and work on 3G which it actually worked very well. Especially at the time when I had that phone, I hardly had 4G anywhere so being able to use data at the same time on 3G was great.
That said, that feature didn't stick around long. The m7 had a separate radio for LTE & 1X meaning you could surf at the same time because it had separate radios. This couldn't do 3G which was a step backwards however 4G was becoming more mature.
Fast forward to today and with your modern tri-band device while it supports multiple bands that the previous phones didn't, most people have no idea what that means they usually assuming if it's a 4G phone well then it's just that how is any different.
I have had plenty of people complain to me about calls going straight to voicemail or signal issues. Rather than having separate radios, Sprint just uses CSFB Circuit Switched fallback so when a call comes in, it lets the phone know via LTE and immediately switches back to 1X to grab the call. That said it's by no means perfect especially in a bad signal LTE area can cause issues. When I'm at home or work I usually set my phone to CDMA only since I have wi-fi there is no advantage to be on LTE, causes issues with calls coming through and wastes battery. Most users have no idea about what is actually going on so it's hard to explain to a friend why when a caller calls them, the caller might here 5-6 rings before the phone even goes off. Sprint's LTE signal frankly sucks in most places I go, even right next to the tower sometimes you won't get full signal.
Anyway if your wifes phone works fine in the same spot as your G and you are doing all your testing off of LTE and still having issues that tells me either you have a bad radio again or something is provisioned wrong. I would put the phone back to stock, reset the radio and reactive the phone then do some testing with calls off LTE again. If you still have issues at the point, I would swap the phone. My M9 is pretty good with CSFB, I haven't had too many issues with it but really I think it's a very poor solution how it works especially when your in a fridge LTE area with the phone bouncing in and out of LTE.
Once the network goes all LTE (god knows how long that will take) I think this will be a thing of the past but for now CSFB now it's here to stay. I don't see Sprint ever going back to separate radios like the previous gen phones as they would more likely be focused on voice over LTE instead.

I'd blame gremlins yes, weird sh*t...and yeah, we still have ipv6 disabled in ROM for wifi

I know about the call switching for LTE and it sucks. But that was not it. I tried CDMA only and it did not fix it.
Disabling WIFI while sleeping is still working. Not one call has gone to voice mail at work in over a week. It used to happen 2-3 times a day.
I HATE disabling wifi while asleep though. I'd like to still get to the bottom of it.
I think some how it is doing something over WIFI when a call comes in, if WIFI is available. But when the WIFI is in power save mode something gets messed up.
The problem started on OMJ's ROM with IPV6 disabled. So it's not that.
The only thing common is Lollipop, Sprint and my WIFI locations (and a modern single radio triband phone).
I'd like to try getting "WIFI Calling" capability off my account. I think once you set it up once, it's enabled automatically on my account.
I will also say, if I do enable WIFI Calling, it's terribly unreliable. Maybe that's a hint.
The WIFI signal is solid and no issues using WIFI itself.

Having Wi-Fi calling provisioned on your account is just that, it just means if you enable wi-fi calling that your phone has the green light to connect and move forward with the server. That said if you keep wi-fi calling off the fact that it is still provisioned on the account doesn't affect anything at all if the service is not active.
If you only solution is disabling wi-fi while sleeping something in the rom is borked. Return the phone to 100% stock, hard reset it (including the radio) then try using it again. While again CSFB isn't perfect, if the phone is CDMA only you just shouldn't be having this kind of issue. If your not having issues with other phones in the same area with calls going to vm, you know it's not the network and something with the phone. If it does this on 100% stock after a re provision then you have a borked radio and the phone should be swapped. Which I have seen borked radios before, the wi-fi radio in the phone is totally separate from the CDMA/LTE radio.

Did that, returned to stock, same issue. Got Another M9, same issue, got a LG G4 same issue. Just signed up for T-Mobile (have not canceled Sprint yet). Two LG V10's. T-Mobile just announced a huge expansion on their network to cover areas that I needed with LTE (Sprint roams 1x Lakes Region and North in NH).

Not a bad play, Sprint's Network has come along way in the past few years but with CSFB and a crappy LTE signal is most places they still have a lot of work to do. One of the reasons I stay is my plan and they are pretty friendly towards rooting/unlocking for the most part.

The V10 was awesome. T-Mobile was extremely good at My work, My wifes work, Home and all places between. Speeds were 4-8x faster (seriously) than Sprint. Simultaneous Voice and Data VoLTE.
But what the map showed up in NH, didn't match reality at all. Sprint is pretty dismal too, but they at least Roam and you can get 1x or 3G from either US Cellar or Verizon.
But T-Mobile had nothing in the areas Sprints Roams. So I'm sticking with Sprint for now.
I've concluded it's a combination of weak locations, the requirement to switch from LTE to CDMA for calls, and something around that is complicated by WIFI while asleep. Shutting off WIFI or shutting it off while asleep definitely improved things but didn't eliminate it completely. Both phones (M9 and G4) are Qualcomm chips and probably have similar Radio Firmware. But it's overly complicated due to Sprint being a bit behind the ball with VoLTE.
I agree Sprint is not quite so tight on locking things down. T-Mobile is the least locked down, then Sprint, then AT&T then Verizon. I know Verizon would perform flawlessly. But the combination of expense and being so locked down keeps me away. T-Mobile price was really good 2 lines 10GB each, with Carry Over and free Music/Video streaming. And the V10 already had TWRP on day one. The G4 on Sprint does not have TWRP and probably never will. It is rootable, barely.
I convinced my Sister to switch to T-Mobile because she wanted an iPhone and I recommended she not Jail Break it. But she wanted Tether (I was rooting Androids on Sprint for her). She is very happy with T-Mobile. And she generally stays in Eastern MA.
We'll see what HTC does this next time around. But they really need to step up their game. The reception issue really isn't an "HTC" issue. It's a Qualcomm/Sprint issue in my opinion. It's a kludge and I think Sprint is the only one with this kludge.
