missed calls & sms ... suddenly!!!

hi,
from time to time I experience the folowing:
Suddenly, soemone call me to other phone becuase he's trying to contact me. I see my artemis and it's OK, switched on and signal bars at 90%. I dont know why when someone try to call me appears like the phone is switched off.
I make a soft reset and strat to receive missed calls + sms's.
I have Vanilla 4.02 ROM and I use very often the wifi connection....
br.

im with you there, this is the reason why i went back to my aging nokia 6280. ive tried about 10 different roms and it would never pick up the signal unless rebooted. what happens with mine and a few of my friends was on london underground you would lose the signal obviously underground, when you came out the phone would pick up the signal but never recieve a call or sms. also the gprs wouldnt connect unless it was rebooted. ive had a few htcs in the past but because of this poor show i wont ever purchase another one.
my phone done this from day one of ownership, tmobile told me that firmware upgrades would fix this annoying problem, but it never did.

maybe you should try updating your radio ROMs
flashing different ROMs wont help

done half a dozen of them as well on my phone.

Even, I had the same problem, but since I moved to Radio version 3.21.XX, everything is just fine, no problems since then. Even 3.24.XX is out now, you should definitely give it a try. Hope it works for you!!
Cheers!

Same problem
Thanks for posting. I have the same problem with the same ROM. I'll change radio rom.

Radio Rom changed
Radio Rom changed 3.34.90 . No problems and good quality

[Q] Call Disconnected - Any Advice?

I've been seeing this problem for a few weeks now, with several different ROMs, including the original rooted stock ROM now. In nearly all of my recent calls, I get disconnected one or more times with the message "Call disconnected" and a "Dismiss" button. I'm thinking that this is because of my EVO and not the other side, since usually if they accidentally hang up or something the call just ends without a message box. As far as I can tell, I have good reception (at least according to the bars), and this is happening at home, where I've not had the problem before.
Does anyone know what could be causing this? My wife's EVO is not rooted, and she does not seem to be having this problem. But then again, I've not had the problem until fairly recently either. I've tried updating my profile and PRL with each new ROM, but it doesn't seem to have made a difference. Anyone have any suggestions as to how to stop this from happening?

Go into the settings menu andbupdate both your PRL and your profile. That *should* help with reception related issues.

Unfortunately, I've tried both of those things. I just did some testing today, and it seems that my phone is unable to stay connected during a phone call for more than five minutes before disconnecting, even if I don't touch the phone and just leave it sitting on a table.
Any other ideas? As far as I know, I haven't ever flashed my radio away from its default (2.15.00.11.19), and I'm currently using the leaked stock gingerbread ROM (build number 4.12.651.1 CL41771 release-keys and kernel 2.6.35.10-gaa602b7 [email protected] #1).
Maybe it's time to unroot and contact Sprint?

You can try downgrading from 2.15.00.11.19 to 2.15.00.09.01. You can download it from http://www.mediafire.com/file/jyedjkp1bm5amwm/EVO_Radio_2.15.00.09.01.zip
Afterwards, go into recovery, wipe cache & dalvik cache then flash the zip. You will be taken to the radio update screen and appear to hang. don't worry or get impatient. After it is finished, you will reboot into recovery and see the words "clearing cache" at the top of the screen. Simply select reboot and then you will boot to your homescreen. The initial boot will take a tad longer since it will be rebuilding the dalvik.

Hmm... I'm hesitant to downgrade my radio because my wife has an EVO with the same radio version number and hers doesn't have this problem. Granted, she is not rooted...

I understand. I've downgraded and upgraded everything several times for testing purposes and troubleshooting purposes and have never had a problem. The only hing about flashing radios is patience and not to pull the battery. Anyway, you can always call Sprint and see if they can troubleshoot it for you from their end.

I would contact sprint @ 877-809-6696 (advanced tech supp). Ask them to push a full reprovision to your device. See if that helps any. I was having issues when when on the airave, I was unable to receive incoming calls. This corrected it. I did try all the other steps listed above without any success.

This is interesting. I unrooted to test things out before calling Sprint, and the problem went away. I was able to stay connected for an hour (where before I couldn't last longer than 10-15 minutes). Yay, fixed, right? So, I rooted again and didn't install any ROMs or anything, just rooted, and the problem came back.
So, I have a solution, but I don't like it very much because it means I need to stay unrooted. Anyone have any idea why simply rooting the phone with Unrevoked 3 (and doing nothing else) could cause calls to disconnect? I'd love to be able to root again, but I can't deal with a phone that randomly disconnects all the time.

I am interested in this as well as I am rooted using unrevoked and get disconnected as well. I do find that it mainly happens though talking to people who have service on AT&T.. Quite wierd. All I hear is a beep then disconnected. This happens when I first place a call and it rings once or twice then beep, disconnected...

This may not be related to rooting. I'm still communicating with Sprint about this issue, and along they way they replaced my phone entirely, and the problem is still happening. Very frustrating, but it makes it very clear that the problem actually has nothing to do with the hardware. I'm pretty sure there is some network configuration problem on their end now. I'm waiting to root my new phone until this issue has been resolved. It is killing me!

So whats the final call on this ..?
Is it Rooting , Is it network .. i am too getting psyche with this .

I'm pretty sure it is not rooting. But I don't yet know for certain what it is. Sprint thought there might be something wrong with the antenna on my phone, but they had already replaced the phone, so I think that is unlikely. They gave me a femtocell range extender to use in my house. Basically, I plug it into my broadband connection, and it is like having a mini cell tower in my house, giving me a very strong connection. Sure enough, when connected to that, I haven't had any calls drop. However, my phone still sometimes doesn't connect to the femtocell and instead connects to some other tower for some reason. My wife's phone doesn't do this, so I still think there is something wrong with my phone. I may contact Sprint again about this. ...sigh...

What is your area some area evo don't work properly like on rahim yar khan in this time connection don't work properly some signal drop and some time up i sure after few day signal work properly then problems will be solve.

My phone EVO is doing this now as well. Has anyone heard/read a solution?

I am having the same issue, out of the blue. No problems up until a few days ago. I'm wondering if it is maybe an issue with a certain version of the Evo. I have a version 002. Thoughts?

[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'm on the FreeGS3 R3 rom with stock kernal.

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.

Need more info....download samsung phone info and post a screenshot of the firmware tab. If your bootlader and baseband dont match, theres your problem. If they do, try reflashing stock (twice) then doing a tactory reset from the stock recovery right after. If after that the issue is still present....probably something else.....mabey hardware related. Good luckl

Do you use bluetooth? I had a very similar problem and figured out that the only time I had call audio was when I was using a bluetooth headset or the bluetooth in my car. I don't know what sets it off but I've done some searching on this problem and it appears to be common among GSM GS4 owners, and even doing stuff like a complete reset doesn't fix it.
The one fix that I did find, that helped some people, was to go into Google Now and disable "Okay Google" detection from any screen. Several people found that that worked. But I didn't have that feature enabled anyway so it didn't apply.
I don't know if the same problem occurs with CDMA GS4s; my wife has a Sprint GS4 and doesn't have the problem but that doesn't mean it doesn't exist. I think it was just AT&T and T-Mobile GS4 owners who reported this.

Edit:
Nevermind. It worked twice then I tried calling a different phone and it broke again. I will keep searching and update.
Original:
I have had this issue intermittently for the past year. It was fixed for about 6 months then two weeks ago started occurring again. Today I flashed a new Rom (PacMan) and the M919UVUFOK3_M919TMBFOK3_TMB firmware. That did not fix it. I was connecting to a 5Ghz WiFi so on a whim I forgot that network and made a call without WiFi enabled. Call worked!
So I connected to my 2.4Ghz WiFi and it is working again. I would try turning off WiFi and see if your calls go through if so it could be 5Ghz or the router...maybe a forget network / reconnect to network will fix it consistently.
Hope this helps you and if anything new comes up I will let you know.

So an update. I finally just gave up on it. My wife had an old phone I remembered (from 2 - 3 years ago) that was ran over and the digitizer broke. I just took her guts and put it in my phone and now it magically works. Hopefully it stays that way.
Should have done this years ago as my phone would no longer charge with the USB Cable nor was my SD Card accessible. Now it is all functioning right again.

So after flashing stock NB4 twice.....and factory resetting after from stock recovery, your still not getting call audio?.....doesnt make sense....try again and make sure the bootloader and baseband match.....and dont reboot into download from the OS.

For anyone having issues with no call audio through cell service but for some reason it works through data calls through whats app or facebook messenger, etc ,i have been having the same problem for awhile now. I believe i have traced it to be a hardware issue with the middle frame, when looking at the phone with the battery cover open on the top right over by where there are two markings R1 and L1. There is a module there labeled J-AT TMGA 7-3. When i was having issues i noticed that if i put slight pressure on that module my audio would fade back in on the call but if i put too much pressure it goes away again. If it is a hardware connectivity issue it would explain why slunked was able to get his phone working again by changing the guts in the unit. Im currently waiting for a middle frame and a blue cable for the antenna to confirm if this is indeed the issue.
