Can't receive calls, but can make calls and texts - One (M8) Q&A, Help & Troubleshooting

Just happened yesterday out of nowhere. On AT&T, but there's no HD call coverage here in Honolulu, so that wasn't the problem. People calling me goes straight to voicemail, but I can make calls and texts and receive texts. Thought it was a rom issue, so I did a clean flash on the most recent SD rom, but no luck. Kind of out of ideas now

There was a rash of posts by folks not receiving calls/texts all over the AT&T forum a month or 2 ago. Pretty sure that instance was network related. If you didn't change anything on the phone (like you said "out of nowhere") I'm guessing the same is true in this case.

i had the same. they enabled HDVoice which is their voice over LTE branding. It doesnt work with non AT&T roms. I got into with them on the phone. they said they couldn't turn it off. i called in a few times. it sounded like complete BS, but the tier 2 person created a tag & escalated it up. It just started working a day later.
you can go into your phones hidden settings for the time being & turn off 4G. It sucks, but at least your calls come through

[Q]T-mobile Wifi-Calling and echo problems?

Just got the Samsung Galaxy S3 for T-mobile and have been experiencing a few strange issues with general call quality. About 2 or 3 mins into a call via wifi-calling, sound from the other side will just cut out. The call is still connected and I am then forced to hang-up and redial. This has happened already on 3 separate occasions. Calls off wifi-calling did not experience this issue albeit I could hear an echo of myself =(. Redialing and asking the other party to call me did not resolve the echo issue. The other party did not hear the echo.
Anyone else experiencing these types of issues or know of any fixes? Since it's only my first day with the phone, I'm hoping these are only fluke occurrences...

Yeap has happened to me calling out of town and in town numbers. Sounds like a dead line, and then when u talk u get an echo. I was advised by the people on the other line that they could hear me. This has happened while on the network due to I don't use Wi-Fi calling.

Anyone else have any wificalling issues?

My issue is more on loosing connection to the server while the phone is in asleep. the wifi connection is not lost just the connection to the server is lost and then my battery gets lost on locating connection.any ideas on that ?

I normally use wifi calling, but today at work and at home (so two different connections and two different routers) I tried to answer an incoming call, but the caller could not here me. I pressed the end button, and the dialer froze for about a minute before saying the dialer stopped responding and requested me to close it. Tested several more times before wiping my phone and reloading my rom fresh. Did the same thing afterwords. Then I turned off wifi calling and the normal network calling worked fine. Maybe a tmo server issue?

word for word same issues im having, also 2 different routers.:crying:

Although I am not certain if this problem exited before rooting and flashing my phone, my WiFi Calling has not been working. I can place the call, but I cannot hear it ring or hear anything when calling. I can receive calls, but once I answer, I cannot hear anything. I am able to receive text messages normally.
I have resorted to switching to the cellular preferred only option. I hope there will be a remedy for this issue.

I am running Whitehawks STOCK TVALUEM999 ROM with none of these issues. I am only on wifi as thats all I have available and I do not have an issues. It's possible that the removal of all the T-Mobile Bloatware, or some Mods done could be causing this. I have great battery life on that ROM and everything works fine. I am excited about this ROM, but am waiting to see another release come out and see how that works. ALSO, get ROM Manager, update to the newest CWM and try a data/dalvick cache, factory reset and install from zip from internal SD. Let me know how that works out

I use Wi-Fi calling exclusively when I'm at home. I'm rooted but still using Touchwiz.
I haven't had any echo problems. I think the quality overall is pretty bad though. For lack of being able to think of anything better atm, I'll just say it sounds rough. It was something that really bothered me at 1st, but I guess I'm kind of getting used to it. There are times I've thought the call was lost bc the call becomes so silent (clear and empty), but after a moment, I can hear them again and the call continues.
My husband switched over to T-Mobile about two weeks before I got the S3 and switched over from Verizon. While using the Wi-Fi calling, I've lost a call or two so far. My husband, who has an HTC One S, has also lost a call or two and he thinks the quality of his calls are fairly poor also.
I'm wondering if it's not necessarily a S3 thing, but perhaps a T-Mobile thing???
That being said... There are times he has full Wi-Fi bars and I have barely anything, and when I check the signal my laptop is getting, that's full as well. When I check the Battery from Settings, I always only have a yellow bar that is frequently dotted with sections of red.
The Wi-Fi issue, whatever the hell it is, is really the only bummer about the phone for me.

I am not sure if what to tell you, but I am in Afghanistan with the Samsung GS3 rooted, and I do not have a single issue with call quality with some of the crapiest internet connections you can ask for.. No echo, no dropped calls. Your internet connection quality can make a difference, when you make phone calls, any downloads going on can hinder the quality, also the type of router u have makes a difference. A wireless N router with 300MBS per second would be ideal...
It doesnt matter if your are using Touchwiz, the rom you are using matters, no other threads are stating this issue. I suggest you try another rom like redruM cause he just released a new update today, or Whitehaws STOCK. It performs great and has CIQ removed, zipalign on boot, some T-Mobile bloat removed, no force closes on any apps and good battery.. It doesn't have the crazy scripts and 4 in 1 reboot, however, if u dont care about that and you want stable and root, its a good option

According to T-Mobile technical support, they have escalated the issue of wifi-calling and wifi connectivity issues to Samsung and supposedly there is a team working on this. Supposedly they will be doing an over the air update.

it doesn't seem like a lot of us is having this problem, could it be the phone itself? i was fine until a couple of days ago. now i am having the same problems as some in this thread; i can hear them but they can't hear me. sometimes it freezes when i answer the call. now i'm thinking if rooting (phone is rooted only) was a probable cause, and if i should do a nandroid restore or system reset??

No wi-fi calling

TMo - GS3
My phone is and has not ever been Rooted. I'm having the same issue that when wi-fi calling is active, if I receive a call, the caller cannot hear me, and then the app. hangs for a minute when I hit end or the caller hangs up. I tried it on a couple networks. I thought I was able to make wi-fi calls, but that seems to not work all the time, either.
I believe this is the first TMo ICS phone, right? I had a 4.0.3 custom (Passion) ROM on my Vibrant (GS1), but since there wasn't ICS TMo phone, there was no wi-fi calling app. on it.
I called T-Mo support and told them I found this thread with other users with the same problem, but they didn't say anything was in the works. Samsung support gave me their usual answer, of doing a factory reset, reinstalling and reconfiguring everything (yeah right).

I get the hang sometimes and I also get the problem of people not being able to hear me when I pick up. Annoying. I got rid of my amaze after the ICS update because it screwed up wifi calling(delay in voice 5-10sec). Piss poor. Wish it worked better because I don't get a cell signal in my house.

To get rid of the voice echo - disable the noise cancelation during a phone call in the in call menu. The noise cancelation uses two mics but unfortunately picks up the noise of the speaker as well, causing the echo effect.

when i first got my s3 i had the wifi calling on and i'd miss calls. people said that it didn't even ring just went right to voice mail. on the occasion that a call actually went through people couldn't hear me and for me they cut in and out. i gave up and stopped using it.
when i bought the phone i was told that when on wifi calling the minutes didn't count against my plan, but reading the manual i got the impression that they did. which is correct?

You have to have them add the free WiFi calling feature to your plan and then they don't count. Just tell them you want your minutes on wifi to be free. There is no extra charge after they add that code.

I'm having the same issue, wifi calling does not work. No one on the other end when I answer incoming calls. Can't connect out.

For me it works sometimes and sometimes it doesn't I just turn it off, I use 200 minutes so far this month and today is the last day so I'm good with 500 minutes plan

Did any of you with the wifi calling problem install Skype? My first phone had the problem of no one hearing me and freezing when hanging up. I ended up returning it to Tmobile for another phone.
Right before I returned the old phone I did some testing. I flashed it back to stock and it didn't fix the problem, but when I wiped the data and cache in download mode, it seemed to help with the wifi calling, not sure how consistent it worked, but at least for the first call I can hear them and vice versa.
So I'm thinking something I installed may have played a factor, and right now my suspicion is that it's skype. I haven't installed it on my new phone since I don't want to screw the wifi calling on there.

Cannot Answer Calls With WiFi Connection

I upgraded to the Galaxy S III from the Vibrant. I had no problems with my Vibrant making or receiving WiFi calls on the secured WiFi networks at home and at the office. However, I am having serious problems with WiFi calling on the S III.
I can make calls (most of the time) and can send and receive texts in WiFi but I cannot answer a call. The phone either does not ring and the call goes straight to voicemail or I hear the phone ring, answer the call and can hear the other party, but they cannot hear me.
I called tech support who had me do a factory reset. That worked briefly, but within 24 hours, I was back where I started. My 911 location situation is sorted, so that is not the problem. I am also close enough to the routers that I do not believe that is the problem either.
My first suspicion was a bad sim card but another co-worker of mine who also has an S III cannot answer WiFi calls in the office either. Now, I suspect some network security issue is causing the problem on both networks I regularly use, but do not understand why considering my Vibrant had no problems at all.

I, too, cannot hear the other party when answering on Wi-Fi. It worked fine at first but now it doesn't. Anyone know of a fix?

The other thing that happens when people call me is that the phone will ring once and then go to a busy signal.
I went to a T Mobile store and replaced the sim card. They also made some test calls to my phone without success. I also upgraded the firmware on my home wireless router. In the end, nothing worked and Tech Support is sending me a replacement phone.

My replacement phone arrived and it initially did not work either. After several hours of experimenting and getting results that weren't always easy to duplicate I have reached the following conclusions:
1. There was indeed something wrong with the original phone.
2. Both phones could answer WiFi calls straight out of the box, but as soon as I altered the Setup or downloaded apps, they wouldn't.
3. I strongly suspect that either the power saving settings or the voice cmd for apps settings are incompatible with receiving WiFi calls. I could not determine that any individual app caused a conflict. When I ran into troubles with the replacement phone, I could restart it and get it to work after altering the phone's settings. I never could get the original phone to do so, however.
4. WiFi calling is still wonkier than it should be compared to my Vibrant. I am still getting calls that go straight into voice mail without the phone ringing, or the caller will hear my phone ring once or twice before it goes to a fast busy signal. I at least feel comfortable that if I hear the phone ring I can answer it, where I couldn't do so before.

[Q] Text messages and calls not being received

I've been having a problem with receiving texts sometimes and I recently noticed that it happens with call apparently. The issue is that I'm texting people back and forth and then all of a sudden I wont receive messages for a long time (couple hours). At some point, someone's text message will push through all of the other ones all at the same time. Sometimes when I assume i'm having this issue, I will send a text to myself and it will push the other ones through as well. Recently though I was made aware that during this "outage", I also was not able to receive phone calls at all. The signal is strong at all times (3-4 bars). Also happens when I'm home all day and not changing locations when it will suddenly stop getting texts and calls. Does anyone know how to fix this issue? I restarted the phone and changed cell towers with the Airplane mode many times and the issue continues to happen at random times. It is really inconvenient. Suggestions?
Technical details: I use the stock 4.1.1 Rom that comes with AT&T S3. I do have LTE in my area.

And now it has happened 3 days in a row but at different times of day. This is a huge problem for me as I use my phone a lot. Any help would be appreciated

TRy making sure yiur not in airplane mode. i was stuck in airplane for a week ._____________.:cyclops:

That's weird. Re-seat your SIM card, if that doesn't do anything then take a trip to your nearest AT&T store/dealer and have them swap out your SIM card and see if it still occurs after that.

I had a similar problem a while back and it happened to be a network problem with my carrier. Gave them a call and all is fine now.

It happend to me too. I went to att store and get new sim. No problem for last 15-20 days. Looks like i got stronger signal too.

Just to give anyone interested in this an update:
I went to the AT&T store today and told them my issue so they told me to go to the nearest AT&T device support center (which was really far away). People over there told me they heard about this issue many times over the past couple of months. The guy working there had a S3 and said he has the same problem. They received an email from the higher-ups this morning specifically talking about this random outage thing I have and that they are currently working on it. They were told to not exchange phones or sim cards because of this since it wont help. The issue involves a combination of Network and Jelly Bean software problems and happens on all new LTE devices that have Jelly Bean from AT&T. They told me to check periodically if there is a solution.
I guess I just gotta wait. Unless someone recommends a ROM that is not based on the latest AT&T jelly bean?

Bumping it up, both me and my wife have had this happen. From what im read its a pretty widespread deal.
Anyone know of a work around at least until they fix it?

Keep us updated
Same problem here - switched from Verizon to AT&T last month and started noticing this problem a few weeks ago. Back then a Google search didn't find much on it, but this thread looks promising.
Just to add my two cents: I'm on a rooted S3 with task650's AOKP (4.2.1) build 12.23.2012 (link). Made sure to flash the modem for my phone (I747UCLI5 from here). Problem: phone randomly won't receive calls or texts. Sometimes calling someone will fix it.
I read somewhere that on AT&T, calls and texts are received over 3G and sometimes phones have difficulty switching from 4G. Anyone know if this is true?

Do a full wipe /system, /data, /cache, /dalvik cache. And your problems should be gone 9 times out of 10 that's usually everybodys problem

Seems to still be working fine.

I started a thread on this also and just yesterday received some info from AT&T tech.
http://forum.xda-developers.com/showthread.php?t=2123974

guys,
it is an ATT issue,
here is a temp solution for a fix:
1) With phone on, take off back cover and press your SIM card so it releases from the spring. It won't come all the way out as it's blocked by the battery. This seems fine - I didn't bother trying to force it out as I didn't want to break anything...
2) Once you see the message that the SIM card is removed, go to the dialer and dial *#2263#
3) You should see a menu with band selections. The current setting is "Automatic". If you switch to "GSM All", you will be EDGE (2G). If you switch to "WCDMA All", you will be on HSPA+ (3G, though AT&T and others call it 4G).
4) Press the SIM card back into place until it clicks. For whatever reason the phone will not recognize it until you reboot. Upon reboot you should see your new setting in effect
please see, post, comment here:

[SOLVED] Can't receive calls.....but I can make them? (very detailed thread)

I'm having a VERY specific issue with my ATT M8 that I can't seem to figure out. First and foremost, I've tried wiping all partitions and starting over....with 3 different ROMS (Liquid, Candy5, Bliss Pop) and none of them allow me to RECEIVE calls. I've even done an RUU back COMPLETELY to stock everything using the ATT stock Lollipop RUU image. When I boot the stock RUU I can again receive calls. Below is the detailed info on the scenario....
Can't receive calls but I'm notified if someone leaves a voice mail.
Making calls from my phone works fine.
If I'm on the phone and someone calls me the phone notifies me like it normally would.
When someone tries to call me, they hear it ring the proper number of times and it does NOT go straight to voice mail.
That last bullet is VERY important. The fact the call doesn't go straight to voice mail is an indication the ATT network knows my phone is indeed powered on and available. Strangely though, it doesn't ring or do anything to otherwise show someone is trying to call.
At this point I'm really stumped. How on Earth is this even possible? Especially after doing the RUU and having the phone work as intended only to try and flash any other ROM later and have it not receive calls. I'm 100% stumped and really need y'alls help.!
**SOLUTION BELOW**
Apparently AT&T is rolling out HD Voice in many areas. It's basically voice over LTE and it's not compatible with many custom ROMS. This is why flashing the stock AT&T RUU made everything work just fine but when I tried ANY custom ROM it wouldn't work.
If this happens to you try the following....disable LTE by turning off mobile data or simply switching to 3G. Then try to call yourself or have someone call you. If the call comes through on your handset it's due to HD Voice having been activated on your account. I called AT&T and explained that I needed HD Voice turned off for my account. You'll likely have to talk to tech support. Ask them when it was activated on your account. Mine was activated last week which is the EXACT time I started having issues. The AT&T tech will ask that you power down the phone whilst they make the changes. Then turn your phone back on (with LTE active) and try a test call. It should work for you.
Big thanks to @redpoint73 for helping me figure this out!

I'm wondering if after doing the RUU my radio or something isn't at a proper level. Attached is a screenshot of my current bootloader. Anyone see something out of the ordinary that needs updating?

Yeah, I would go ahead and check with ATT if there are any bars on your account. Sounds like more of a network issue than a phone issue.

Thanks for the reply! What would lead you to believe it's a network issue? I can make calls just fine and if I'm on the phone and someone calls me it works as if it normally would. Only issue is when someone calls me and I'm NOT on the phone.

Try turning off LTE, and see if you can get calls.
Some folks have been having issues with "international" based Sense ROMs not playing well with AT&T's LTE network upgrades (in preparation for Voice Over LTE). Not sure if this affects AOSP ROMs, but I have a feeling this is the problem.

As I already described, AT&T is upgrading their LTE network for Voice Over LTE (they call it "HD Voice") and something in that upgrade doesn't seem to be playing well for some people on international based custom ROMs. In addition to voice call problems, you will probably also find SMS messages won't work on LTE.
Curiously, the problem seems to be very location specific. I've been running Skydragon Sense and LeeDroid for a few months, and on AT&T network. And everything has been working fine for me at my home location, as well as a few other locations around the country (I travel pretty occasionally for work). These are some of the ROM that others have had AT&T LTE issues with; and at one point even in the same city as another user that was suffering this issue (Chicago area). But for me, everything seemed to work fine.
The only real fix is to go back to stock AT&T based ROM. Folks have tried to flash various radios, and other things with no luck. Team Venom (Viper ROM) also said they would look into it a few months ago; but I don't think anything ever came of that.
An ingenious workaround posted by another user (if you want to stay on an international ROM): call AT&T and ask them to turn off HD Voice for your account. So you can still use LTE for data, but the call bug won't occur.
Of course, the downside for this is that you won't be able to utilize HD Voice. But that is probably the lesser of evils, if you want to stay on the current ROM.

As I already described, AT&T is upgrading their LTE network for Voice Over LTE (they call it "HD Voice") and something in that upgrade doesn't seem to be playing well for some people on international based custom ROMs.

This is brilliant. I'll give it a shot. Thanks for your help!

I agree, its a good workaround. Especially since HD Voice requires users on both ends of the call to have a phone that supports the feature; and few phones for the time being have it. So having HD Voice turned off on your account (even if its deployed in your area) is probably mostly irrelevant.

Just got off the phone with AT&T and everything is just peachy again. I updated the first post with the solution/fix. Thanks so much for your help!

Ask them when it was activated on your account. Mine was activated last week which is the EXACT time I started having issues.

Interesting. I wonder if HD Voice hasn't been activated on my account yet; and that is why I haven't had this issue while others have?

It's certainly possible. I live in Dallas which is a fairly large area. It wouldn't surprise me if we were one of the areas that got it first. Sucks being a guinea pig but I've left a trail of breadcrumbs for everyone else to follow.

I'm in Boston area, and according to the AT&T maps, HD Voice is working here.
Although, I got the M8 long before it supported the feature (they added it with the 4.4.4 OTA). So I don't know how they decide when to activate it on your account; but if its device related, I can see how it might not be on mine yet.

I'm having a VERY specific issue with my ATT M8 that I can't seem to figure out. First and foremost, I've tried wiping all partitions and starting over....with 3 different ROMS (Liquid, Candy5, Bliss Pop) and none of them allow me to RECEIVE calls. I've even done an RUU back COMPLETELY to stock everything using the ATT stock Lollipop RUU image. When I boot the stock RUU I can again receive calls. Below is the detailed info on the scenario....
Can't receive calls but I'm notified if someone leaves a voice mail.
Making calls from my phone works fine.
If I'm on the phone and someone calls me the phone notifies me like it normally would.
When someone tries to call me, they hear it ring the proper number of times and it does NOT go straight to voice mail.
That last bullet is VERY important. The fact the call doesn't go straight to voice mail is an indication the ATT network knows my phone is indeed powered on and available. Strangely though, it doesn't ring or do anything to otherwise show someone is trying to call.
At this point I'm really stumped. How on Earth is this even possible? Especially after doing the RUU and having the phone work as intended only to try and flash any other ROM later and have it not receive calls. I'm 100% stumped and really need y'alls help.!
**SOLUTION BELOW**
Apparently AT&T is rolling out HD Voice in many areas. It's basically voice over LTE and it's not compatible with many custom ROMS. This is why flashing the stock AT&T RUU made everything work just fine but when I tried ANY custom ROM it wouldn't work.
If this happens to you try the following....disable LTE by turning off mobile data or simply switching to 3G. Then try to call yourself or have someone call you. If the call comes through on your handset it's due to HD Voice having been activated on your account. I called AT&T and explained that I needed HD Voice turned off for my account. You'll likely have to talk to tech support. Ask them when it was activated on your account. Mine was activated last week which is the EXACT time I started having issues. The AT&T tech will ask that you power down the phone whilst they make the changes. Then turn your phone back on (with LTE active) and try a test call. It should work for you.
Big thanks to @redpoint73 for helping me figure this out!

Thanks for the post this helped me with my issue!!!

Have any of you tried to disable enhanced 4G LTE Mode in network settings instead of slowing you down to 3g?

If you are on AT&T and suffering this problem, my advice would be to call AT&T and ask them to turn off HD Voice on your account. The enhanced LTE setting on the phone does nothing to help this problem.

Gotcha.

Unable to receive phone calls

Hi everyone,
I have a Sprint HTC 10 that I've sim unlocked. I'm running Mint Sim (a T-Mobile MVNO). This has been working perfectly for 2 months now. Yesterday I was told several times that my phone sent incoming calls directly to voicemail. I tried calling myself with my work phone and it goes to voicemail right after the first ring. I popped out my sim and put it in my Nexus 4 which rang immediately with an incoming call.
I tried several roms, PureFusion, Lineage, and Viper, same with all of them. I'm able to receive texts, send texts and mms, and make calls, but incoming calls go to voicemail. I just ran a RUU to the latest image for the Sprint device. Does anyone have any suggestions as to why this may be happening and what I can do to fix it?
I'm currently S-On, so no ability to downgrade firmware.

Since you say the sim worked on a nexus 4, the problem is definitely within your sprint phone. Just from a bit of googling it seems CID or some form of editing your radio would have been necesary to make it work. Idk what the problem is but the radio settings is where you want to look.

That was my first thought, but it didn't make sense that I'd lose my ability to receive calls after 2 months of it working well. I went S-off, downgraded, reran the latest ruu, wiped modemst1 and 2, re-unlocked the Sim, and still having the issue.
I then tried the sim in two more phones, both gsm unlocked, and had the same problem in them. I tried it again in the Nexus 4 and could make and receive calls, but no data anymore. Trying an AT&T sim in my phone I could receive calls just fine.
I pressured Mint and they're going to send me a replacement sim for free, so hopefully that'll fix the issue.

nice! i've had bad or outdated sims before lol didn't think that was much of an issue anymore, but no that you say that I'm sure it'll fix it. last thing i would've said if APN changed but sounds like that might not be it either.

Weirder still, I went into town today (I live in the boonies but get 3-4 bars, LTE data, and I max out the Mint throttle) and my phone rang. Now that I'm back home it's working again. Maybe the tower just didn't like me and now that I've checked in on another one it'll work.
Edit
And now 20 minutes later it's going directly to voicemail again.
