As the subject says recently when i turn off 3g to use edge and then go to turn back it wont let me
The only way i can get back to 3g is to turn data off and on manually by hitting airplane mode
Any suggestions?
Thanks
no one else has this issue?
I have the same issue it takes a long time to get 3g, I'm with vodafone au so the network is horrible. This might be the issue that the phone can get the troubled network.

I have this issue. Only fix I've found is airplane mode/battery pull.
However, if the phone automatically switches down to edge (2g), it will usually switch back on its own.
Don't even get me started on the frequent complete data shut-downs though, and that's with what little there is of the signal present. Completely ruined Google Voice functionality.

Well IM on ATT in the northeast US. I upgraded my radio from XX to UCK and I think it solved the issue for the most. A lot of outages here tho after our storm (apparently only on ATT tho as USUAL since verizon and sprint seem to be fine. ATT blows!
I have the ATT HOX and want to disable LTE due to the known issues with missed calls etc. Would it be possible to disable it through root access WITHOUT installing a custom ROM?
I'm not sure what AT&T do to their phones but can you not change it via Settings > Mobile Network > Network mode.

Same on Telstra
Phone: HTC One XL
ROM: AOKP 4.2.1 MR1 preview w/ alloy blue theme
Launcher: Apex w/glaskart icons
Att one x doesn't have that function. Try to do it in service menu trying typing in *#*#4636#*#*
Go to phone info and scroll down. It works for me on clean Rom but not sure about stock rom

What known missed calls issue? What would LTE have to do with missed calls? LTE on AT&T is data only. It doesn't do anything with calls. You can dial *#*#4636#*#* and try to set it to gsm only or something.

Believe me I have tried. It's not possible. But ik you said you didn't want to, but you really should look into custom ROMs. There's some that are basically stock with just better battery
Except for ATT. Its a well documented fact that they have it disabled. Any changes you make revert back to default.

Its a fairly well known issue with ATT and LTE phones.
As far as I can tell since LTE IS data only it has a hard time receiving calls when its connected to the LTE network. I think it has something to do with only having 1 antenna and it cant communicate on voice and data at the same time. Or, maybe not.:silly: All I know is that when my phone is connected to LTE I will not receive phone calls. All calls will ring a few times and then go to voice mail. I eventually get voice message notifications when the phone switches out of LTE.
Any changes made in the field test mode do not stick. Thank you very much ATT.

I've had 3 different LTE phones on AT&T and never had issues with missed calls and I'm constantly on a LTE connection. My phone kicks to hspa+ right before I receive a call and then it rings. Goes back to LTE about 30 seconds after I hang up. The only thing I can think of is that you are on LTE only in the field test mode thing. That will definitely give you call problems. What does it say that you are connected to when you go into the phone information menu?

I've had a few LTE phones too but I can confirm that this is an issue with AT&T and the HOX. (At least in certain areas.) The phone is *supposed* to do what you said and switch off LTE when a call comes in but that doesn't always happen. I've noticed it the most at my office where I usually have 4 bars of "4G LTE" or one or two bars of "4G". I'll have a long period of time with no incoming calls or texts and then when I make a call (and the phone switches to "4G") I get the backlog of voicemails and text messages. Hard resets haven't helped and AT&T refuses to admit that it's a problem.
Heres a summary of what I have found:
1 Being in field test mode does not affect incoming calls.
2. When making outgoing phone calls with LTE or HSPA displayed in field test mode, the connection will switch to UMTS and then revert back to LTE or HSPA after hanging up. I dont know what that means, just throwing it out there.
3. On a few occasions during my testing I have noticed that I could not receive calls when HSPA is displayed in field test mode. I think that the phone had just switched from LTE, although I havent been able to 100% verify that.
4. My connection at my house varies between LTE, HSPA,EDGE.
5. EDGE is great. My phone makes and receives calls all day long when I have a EDGE connection.
6. Most of my testing has been at home where I have crappy reception to begin with. On a few occasions when I had my wife with me I had her call my phone(connected to LTE). Same as when at home, my pone never rings.

Exactly!
I have Samsung Galaxy S3 on AT&T and I have same issue when connected to LTE. I have been working with AT&T CSR for over a week and no resolution yet. I have talked them into switching my data plan from 300MB LTE to Unlimited Standard Phone data plan. (Unlimited standard phone data plan uses HSPA+ and not LTE, which would resolve the issue)
From what I have understood so far, its not the phone, its the AT&T LTE network.
Wouldnt people with the same phone have more answers for you?

No, because this issue is not related to the phone but its related to AT&T LTE network. So everyone on AT&T LTE network has same issue and not only people with HTC one X.

I was on phone with them last night. They have created a case number for me so their "technical team" can look into it. They promised me to get back to me before friday on this.
For changing the data plan, the CSR tried to change it but it didnt work yesterday. I blame it on the CSR because I know some people on XDA has done that before. I am gonna call them again and have a different CSR try it or me.
And plus, with this change, you get unlimited HSPA+ for just $10.

Thanks for the link. Those settings actually worked for me. I had already tried a couple different APN configs but none of them seemed to stick.
So, now I have successfully disabled LTE.
Unfortunately, I'm still having intermittent missed calls with the phone connected to HSPA. Also, At work in certain areas, we have rock solid LTE reception and guess what...no missed calls. WTFrack?
At home the only time I can get regular calls is when the phone is connected to EDGE.
I seriously think that there must some relationship between 4G/LTE and signal strength. Does anyone know If EDGE and 4G/LTE use the same towers or same power outputs?
Just this morning I noticed I cannot get 4G LTE in a known 4G LTE area where I work.
I've tried toggling Airplane Mode.
I went into Mobile Networks and made sure CDMA/LTE/EVDO was checked
I went into access points and made sure LTE was checked
When I reboot my phone, the access point changes back to EHRPD.
Anyone know of anything else I can try? Looks like it might be a SIM card issue to me. Will I have to go back to stock in order to get a SIM replacement?
Are calls and texts working fine? IMEI the right numbers? If so, I'd give Verizon a call later today to see if its a tower issue. Sounds more like an outage than anything else. If you're stock rooted I'm sure you'd be fine getting a SIM replacement with no problems from Verizon. I haven't gone for one yet so others could provide input there.

Texting and calls are working as expected.
And just like that, 4G is back.
Probably a tower issue, that they have since taken care of...
I literally can't get any calls while connected to LTE. They all go to voicemail. I have been trying to figure this out for days. As soon as I turn off LTE I get calls on 3g with no problems. It also appears that when I'm on LTE if I make a call it had to drop to 3g before the call connects. Data works just fine. I have called sprint but they were less than helpful, updated prl and profile, and tried it in multiple different towns. Anyone have an idea of what to try next?

Whoops accidental thanks lol. If u check the other threads u will know that the way the new tri band phone's work, when on LTE all u get is data, on 3g u get voice and data, so while Ur connected to lte the only way to make or receive calls is for your phone to switch to 3g. This process should be automatic unless u manually changed something to force the phone one lte only.

That is so false because when I'm on LTE at my local mall, I can send and receive texts just fine.... the OP must've messed with some sort of setting is my guess..?
I have not messed with any settings. This has been happening from day 1. It took me about an hour after I got home from the Sprint store to notice that all calls were going directly to voicemail when I'm on 4G. As soon as I turn off 4G I get all my calls with no problem. I have tried updating prl and profile as I said before, but I don't appreciate people assuming I changed some setting when I'm telling you I didn't change anything. When I'm on 4G there is a spark icon that is constantly showing and the signal bar is always showing 1 bar. I don't know if that's part of the problem or not. If anyone has a serious suggestion to help instead of just assuming I caused this please let me know. Thanks.

If I read correctly on the s4gru website then the reason ur having this issue is because the tower is missing the 3g upgrade that handles this handoff which is called Circuit Switched Fallback*or enhanced Circuit Switched Fallback. Here's a link to the s4gru page with this info if u wish to learn more about it.

False again. When at the mall I can make/receive calls as well. You CANNOT use data and be on a call at the same time though (like I could on my S4).

So what your saying is that everything that we know about tri band phones is false? The tri band phones only have 1 antenna so it is impossible to use voice when connected to lte period. When u make a call Sprint kicks you off lte in order to use voice and when the call ends Sprint reconnects you to lte.
eCSFB Gap Issue – What you Need to know:
Smart devices require eCSFB to “fall back” to 3G to accept a voice call if the user is connected to the LTE network.

I never said you can't get a call while on 4G. I said I can't receive a call while my phone is on 4G. Something about my phone or area of service causes my phone not to switch to 3g for incoming calls so the phone never rings

i've been having the same problem! I live on the outskirts of the spark network so i only get the regular lte at home. and i dont believe the towers have been upgraded here yet because i wont recieve calls or texts unless i call out on my phone which forces lte off for 3g etc. but if i drive 15 min. north where the "spark" network is deployed then i'll recieve my calls and texts appropriately because the towers are upgraded there.
so sadly i keep my phone on wifi and cdma mode while at home then whenever i go out i have to switch it to lte/cdma and restart the phone so i can utilize lte while im in a "spark" area.
its tedious and sometimes i forget to switch back when i get home.. its such a pain. Leave it to sprint to deploy phones before their network is even ready for them.

Well the places without the 3g upgrades is not that big so they probably just decided to jump on to tri band even though development wasn't complete. It's like saying they should of waited not not sold any LTE devices until they finished deploying LTE, which means they would of still had old devices being sold.

well i understand that but at least when they first started selling the lte devices; the devices would still received calls and texts. because even though the lte may not have been upgraded/deployed or whatever yet. the cell phones themselves were compatible with the old network as is. but with these spark devices, they are deploying phones that may or may not work (the main point of a phone is being able to send/receive calls or texts etc) depending on where you are because half of the towers aren't upgraded for csfb
"Circuit Switched Fallback is a great solution to the issue of Sprint Triband LTE smartphones. But the problem here is that the Sprint network is being upgraded in Network Vision, and not all Sprint parts of the Sprint network can currently support CSFB. And it affects all Sprint Triband LTE phones, not just the Nexus 5 and LG G2." quote from http://s4gru.com/index.php?/blog%2...-technology/
and the problem here is the phone is supposed to be able to detect that the lte towers in my area dont have csfb and therefore switch back to cdma. But it doesnt, so it stays connected to lte and i never receive any calls or texts. but when i drive north to a spark network area the csfb works appropriately. So this leads me to believe its a network issue and not that my phone is a lemon.
idk maybe im just blowing hot air here but its frustrating that the most important part of my phone does not work properly for whatever reason in my hometown where i spend most of my time.

According to S4GRU what you are saying is wrong. In order for your phone to ring it kicks you off LTE. Circuit Switched Fallback. When you are connected to LTE your phone receives 0 CDMA signals (this includes voice). When sprint is trying to send voice to your phone, if the CDMA cannot be routed to your phone, the LTE network is checked for your phone, if found the LTE network drops you so the CDMA signal can get to your phone.
Give it a try. Make sure you are connected to LTE and data is in use. Have someone call your phone. Watch your LTE indicator change to grayed out, and switch to CDMA before your phone starts ringing.

No ISH, you still receive the call though, that's what I am trying to say..................
This whole thing is extremely depressing, just got this phone today and it's one of the first things I relized..sure I can put it on 3g and sit tight like that but come on the whole point in getting the newest flagship is how it's better than everything else, and sprint can't make it work right (yet). I noticed with my area that as long as the data is not actively loading a page or downloading it will switch to 3g and calls will come in but if it's load strait to voicemail..hope they get it all fixed the way it's supposed to be soon enough.
I've read a few others with this issue. Randomly the phone will seemingly loose connection will not recieve calls or texts until you pick it up and use it. And 50 texts start coming thru. Etc... I'm on T Mobil, have great signal. I've toggled 3g preferred, 4g preferred, and have developer options enabled, keep connection at all times. Still does it. Any thoughts???? Or help would be appreciated

Thanks but this isn't my issue. Phone seems to struggle switching bands. From 4g to 3g and gets hung.
This phone connects to T-mobile 4g fine for data. But for sms and calls it goes to 3g, as it doesn't have VoLTE...seems like it doesn't switch all the time or get hung up. I've tried turning off 4g. This seems to help. But the phone has a definite issue. Not sure if it's considered normal since it's not utilizing 4g for voice and one of the little things you have to live with

There's definitely an issue, and it's not just with the Tmobile sim. Sometimes my china unicom Sim says no service too. But they won't say no service at the same time. It's one or the other. I've tried to switch the sims to other slots but same thing. I know its an issue with the phone because when my phone says no service, i look at my wifes phone and she has full bars on her phone.

Must be a software issue
I have an similar issue... Just it's only for my 3G/4G after 10min of utilization i lost connection (call & sms work fine) and my phone say all is ok (I have the 4G icon...) I forced to disable / enable the Data 1 or 2 times for 3G/4G come back... I have Global Rom & SFR french network
Same problem 10 min data off for like 45 seconds n comes back by itself
Hmm similar problem. Having trouble getting calls on Tmobile. Lots of people calling and going straight to voicemail.
