Hey guys, I haven't done anything to my phone but all of the sudden, the data and phone signal basically quit working. I have a very hard time getting texts, phone calls etc to go though but it will eventually (usually takes a while or a few tries) and as far as data goes, I basically have no connectivity at all unless I'm on wifi. It says 3g or H every once in a while, but it's really slow and usually doesn't stay for long. I'm running CM9, and like I said before I didn't change anything that I'm aware of that would have caused this problem. It worked fine before, and it just stopped. Ideas? Thanks

have you called your provider? maybe its on their end.
I'm having the same exact problem... it shows my 3g it shows all my bars but instead of the bars being colored or the 3g be in color is gray. Also I cannot get back conectivity until I restart the phone. Does anybody have an idea what this is?
Are you on AT&T? I was not having any problems until a certain point in time, and I didn't change or do anything to incite them. I'm not even getting calls anymore, I'll just get all my texts in a wave every few hours. My data is useless, it won't stream, or load web pages, and my phone is frequently saying "Emergency calls only" when I'm sitting at my freaking house (which normally has full 3g and cell signal and is very fast)
This just started occuring with my 9020a on AT&T the first week of March. I switched SIM cards twice, spent about an hour on the phone with ATT, and sent the device back to Samsung who rolled back the software to 2.3.4 and the Radio to UKE1.
I still have the issue. Samsung says its not them. ATT does nothing. It;s liek the phone just stopped working, started dropped calls, missing calls, and the internet connection sucks. I have an iphone for work through ATT as well and have no issues with signal.
ANy help is appreciated.
Hmm
Make sure you have the right, most up to date settings for APN, and flash original radios. if it still doesn't work, make sure you have the i9020A, which has the at&t 3g antenna, not i9020T which has the T-Mobile antenna, vice versa.
Have you tried other radios for your device (make sure you flash the appropriate ones for your model)? Any signal info under Phone Information when dialing *#*#4636#*#*?

Sounds like you're having the exact same problem I am having. I switched sim cards, flashed different roms, etc and nothing. (although to be fair, after the new sim, things work better, but still not well) I'm about ready to pop my sim back in my craptivate and just go with that... or buy an iphone off of craigslist.

I am 100% sure I have the 9020a, but I don't know anything about APN and flashing radios. I have only ever flashed full roms before, so I wouldn't know where to look for the original radio.

I have not tried other radios. The signal info seems solid, sitting at my house, but the 3g is still horridly slow. It taked 15-30 seconds to load a webpage, even a pretty mundane one like google. Messages still come through in waves, and often won't send
About your APN, AT&T should provide you with the proper values to put in under Settings | Wireless & Network | More | Mobile Networks | Access Points Names.
If you are on ICS, they values should populate by themselves.
Can you try flashing other radios and see if you encounter the same problem:

Make sure you backup your EFS folder (and all data for that matter).
I had similar problems, they were related to turning 3g on/off with a APN widget while the phone had little signal. As soon as started enabling and disabling 3g on the android options everything was back normal.

the data works most of the time now it's just retardedly slow. I can't stream music even on low quality, nor can I watch youtube without leaving it for 5 minutes to buffer,pages take forever to load, and I was downloading a 6 meg app and it took 20 minutes to download whenI was leaving the phone alone and not moving. I got really sick of trying to fix it and finally gave it to geeksquad to send in to get replaced. sigh.
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.

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?
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.

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 have to reboot in order for the 4g data to work again but it only stays on for about a minute and then it stops working again. everything else on the phone works ( text, voice, wifi etc...) I read somewhere that flashing different radios might fix it but im not sure about that. anyone else experience this and have a work around? i am currently on baseband i535VRLG1
Thanks In advance
i called Verizon and they said it may be the sim card thats damaged. if that were the case wouldnt voice and text fail as well?

I'm having the same issues recently. I've always gotten a 4G signal at my house (albeit not the strongest one) but lately, my phone will not hold on to the connection. When coming off of wifi, my phone will not acquire a data connection at all most of the time. I can still send/receive texts and calls but there is no 4G or 3G icon, no MMS, and no data. I have to toggle the radios on/off, or change from CDMA/LTE to Global (or GSM) and back, put in airplane mode, or restart.....there is no guarantee any one of those steps will work. Sometimes I have to do it repeatedly until I get my data connection back but it is only temporary.
I'm on the i535VRBMF1 baseband and updated to the ML1 modem to try and resolve but to no avail. I have replaced my sim card (as I initially though that was the issue) but it has not helped either.
The only thing I can think of is that my PRL may have been updated (it is currently 15310) and it's causing issues with the towers in my area.
I just got back from Hawaii and was also in San Diego for a few days and had absolutely no issues. It seems to only be an issue now when I'm at my house which makes me think it is something VZW network related and nothing to do with my phone per say. It's really driving me nuts though.
BTW, I'm in Southern California (Irvine).
I seemed to have fixed the issue by reverting the baseband back to vrlf2. I had to switch from global to 4g/LTE because I vegan to inch roaming charges lol. Verizon credited me and no dropped 4g signal. So I'm happy.

What ROM are you running? I'm just curious what the implications are of running an older baseband (from the ICS days) on a newer ROM/Kernel.
I'm running cleanrom8.1 core edition. Slightly buggy but tolerable.
I was finally able to somewhat resolve my issue so I thought I'd post in case anyone else is experiencing something similar.
By using a few different apps and testing techniques, I was finally able to deduce that my issue had to do with EHRDP hand-off with the towers in the immediate vinicity to my house. I'm not sure what VZW did to them lately but it doesn't appear to be a problem in other locations so it seems like the issue is on their end (and not something to do with my phone).
In any case, it seems that when my 4G connection is weak and EHRDP is detected, it is dropping the connection entirely instead of handing if off to 3G (EVDO). The connection is also never transferred back when a 4G signal is detected either until I reset the connection where there is a moderate 4G signal.
Again, this only seems to be an issue when connected to the towers near my house and doesn't occur when traveling abroad.
To fix this, I have disabled EHRDP by doing the following:
1) Open the dialer and type *#97328640#
2) Select "[2] CDMA"
3) Select "[2] Data"
4) Select "[7] eHRPD e/disable"
5) Select "[2] Disable(*)"
6) Reboot the phone
Now my phone switches between EVDO revA. for 3G (using the native protocols) and LTE rather than relying on the broken eHRDP protocols. This workaround will have to suffice until VZW fixes stuff in my area but at least I don't miss MMS messages anymore.
Hope this helps anyone running into similar situations.
Hi everyone.
I'm having a strange issue with my internet connection. The phone connects to 3G fine, but whenever a go into a zone with no or bad 3G coverage (at work for example) and the phone switches to 2G, it'll sometimes stay in 2G even after going into a good 3G coverage area (at home). It doesn't happen every time, but happens a lot. The only way to make it switch back to 3G is by forcing "WCDMA only" through the *#*#4636#*#* menu. I could just leave it there, but then I'd have no connection at all when I'm at work, so I switch it back to "GSM auto (PRL)".
Usually, when the phone parks in EDGE, the network settings don't change, it stays in "GSM auto (PRL)" but it just won't switch to H. Today, though, it switched to "GSM only" by itself, which it had never done before.
I had this same issue with my previous phone (Huawei ascend P6), so I thought that it was probably a problem with the SIM card, so I asked for a new one but nothing changed.
I've seen a few posts regarding similar issues but most of them are very old and none of them have been very helpful. I hope someone can give me a hand here.

Thanks.
My phone sometimes gets stuck in 3g instead of handing off to LTE. I just toggle airplane mode on and off and it immediately goes to LTE. I know it's not a fix, but it is a pretty quick way to get your data back.
Data connectivity issues are by far the most irritating, considering how much it costs to have a device like this...

Thanks for the suggestion, but unfortunately that doesn't work for me. The only way is through the #*#*4363*#*# menu.
That sucks man.
I'm not sure there is a fix for this. Other than Google fixing it in the baseband. You would think that if the problem were in the source code that this would have been resolved by some of the devs here on XDA. I have had these problems for a few years, and on other devices as well.
I guess I'll have to live with it. Thanks anyway, man.
