WiFi Calling app issues

So today I sent out a picture message to my wife while my WiFi calling was enabled. (I don't have a good signal at my house so this is the only way I can do this from home without moving around looking for a signal) Every time I tried sending the message I got a "g" pop up on the status bar next to my wifi signal bar. I tried rebooting because it wouldn't send and it still didn't work. I then set it down and ignored it and it finally wend, but maybe about 10 minutes later.
The other issue I just has been happening the last couple of days is the app just shuts down when the screen is sleeping. I set my phone down and come back 20 minutes later and the icon is missing. I go into the app to restart it but is says it's on, but trying to connect and it won't connect until I reboot. Just now I had an error message stating I wasn't connected to the tmobile network and had to sign in (or something like that) I rebooted and everything connected back up.
Anyone else had this happen to??

The whole mms thing is not an issue. it sends mms using your data connection to prevent something but i cant remember what. Take a look at the wifi calling thread i know it was addressed already.

I think your WiFi calling shutdown when the screen went sleep because you may have WiFi set to sleep when the screen shuts off.

Rebooting is all fine and dandy, but then I need to have it reroot itself again. And then to overclock it I have to be at my computer.
After looking at the other thread as the first responder suggested it makes sense that the MMS get sent over data connections, so I guess if I need to send an MMS I need to have a good "cell" signal.

i am having the same problem.
from a fresh boot, wifi calling works. but once I shut the screen off, wifi calling is lost and it will not come back until I reboot again.
i am using CM6.1, and I don't know if this is a problem with CM or just the wifi calling app itself

I have this issue as well, wifi icon will go missing, when you opn the app it says that its on...from what ive been hearing, wifi calling doesnt really work that well anyway.

Vibrant randomly loses cell signal ( No network)

Hey guys,
My Vibrant is losing cell signal on its own. It happens randomly like once every couple days. I tried switching to Airplane mode but then I can't switch back to normal mode. This happened on stock, Trigger and Biwinning ROMs.
I have tried reseating the sim card but it still happens. I have also tried in GSM only and GSM and WCDMA mode but that doesn't help either.
The only fix that works is take out the battery and put it back in again. Does this mean I have a bad phone or is there something that can be done?

Are u wiping between flashes??

This has been happening to me on the stock Odin 2.2 build. Think it's the newer KB5 build. Samsung is so full of fail.

If you guys are talking about internet randomly stop working when your on the browser, then yes i can say i have data dropouts too. Im currently on modem KB5 idk if its that or t-mobiles network.

Flash different modem.

Oh I get that too, but I don't think the thread is talking about just data dropping. I woke up this morning to a completely disconnected phone. Not receiving calls. Not receiving texts (not that I ever get any). Nothing. No SIM card found. This after the phone was working perfectly the night before. Nothing changed.
It's really strange. Might try flashing another modem...would that help the SIM card not being recognized?

Thanks guys, I just tried Odin format repartition>KB5 stock and still got the error.
Now it's either the bad sim, kb5 sucks or my phone has a problem. I'm getting a new sim tomorrow

Thanks inconceeeivable. I flashed KB1, we'll be able to narrrow it down soon.. I love this community

My phone went from 3G to EDGE to nothing in about an hour and I restarted the thing 2-3 times and nothing happened. When I finally went to work which is 15 miles away I had full signal no problem. Perhaps it's a network thing?

Thanks but I don't think its network, I get the same problem in Chicago as well. Also my wife's vibrant shows full signal. We traded sim cards and I still see the issue so its NOT sim card either. Now its narrowed down to:
1) KB-5 modem
2) Phone itself
I am still checking and will update the post

I'll Answer your choice....its choice 1) KB5 Modem. This modem is terrible i been using it on 3 different roms and while on this modem my data would freeze/stop randomly really noticeable on downloads and browser. I would be on the browser searching a page and all of a sudden it would not load anymore it would stop. I recently switched back to KB1 and my issues are solved no more data stops/drops. KB5 is really good on GPS but the data is horrible with the freezes/stops. Hope i helped you choose better. Stay away from KB5 if you notice browser loading stopping.

Thanks for sharing your feedback
Today I got the signal error on kb1. Sadly this seems to be a hardware issue with my phone. I also checked to see what my baseband version shows and it shows "unknown"
Then I checked my IMEI and I got "your imei is "" "
So yeah that sucks. The only way to get signal back is take out battery and put it back in.

I did, still the same issue...

I thought it was just me. It was horrible about 2 weeks ago. 2 different modems different solve the problem so I was convinced it was a network problem. I waited it out and they seemed to have fixed it. Instead if an x most of the day I have 1 or 2 bars of edge like before lol

Haven't noticed problems on KA6, but I haven't been using it heavily. (Switching between Vibrant and HD7)
Might be worth a try.
Edit: Also, have you tried Bionix? I know that the same phone never had any problems on 1.3.1. Think it has KB1 though, so it may not make a difference for you.
Sent from my SGH-T959 using XDA Premium App

Thanks guys, I did try Bionix nextgen which I believe is KA6 and didn't see the problem but again its just been 12 hours so far. I bought a dead vibrant with broken screen and just replaced the sim assembly. Let's see if that fixes the problem...

You're not alone. I have the same problem and I've flashed every modem I available. Sometimes I lose cell signal but not often. The data signal is what's spotty for me.

Thanks Blown89.
So when I lose signal, I tried checking IMEI *#06# and I get "null/null" and yes my efs is fine. Once I take out the battery and turn on the phone, it starts to work fine. Tried all software resets...
Any ideas?

No Service

Hello,
I've had my phone for over a week now and it was great until yesterday. Now I am unable to make any calls with it but data still works. I have attached some screen shots below. Any ideas on how I can resolve this?
The problem occurred 2 days after I flashed XWKE2. I tried a factory reset, no change. Then flashing to XWKE1, no change. Then back to XWKE2, no change.
Oh and the sim's not at fault, works perfectly with my I900 Omnia.

Ugh... samsung phones. My galaxy S and Nexus S both have this issue and it seems they still don't know how to fix it.
Usually I would just cycle airplane mode on and off to fix it. Sometimes that would cause the phone to never come out of airplane mode though... in that case I had to restart the phone.

O2 are suffering outage on their system at the mo. Just Google "O2 outage" for details.
Started yesterday and is continuing, they have engineers working on the problem.

try changing your radio band to gsm only..maybe that will help for some troubleshooting

They should really tell their affected customers when something like this happens. This most likely is the reason as I tried making a call using the same sim in my Omnia and it didn't work. Thanks for the heads up.

There was a theft of equipment at a site near London, and it knocked out a large area of the country...
Goodness knows why a site of such strategic importance is unmanned, but it has caused a large blackspot...

Looks like service is back up now, for me at least. I probably should have googled 'o2 outage' before I reflashed my phone, but now I've turned off sending google usage data so hopefully my battery life will improve.

Seems like yours might be more a case of ID TEN T error more than anything else because I've never experienced that on the Galaxy S or this Galaxy S II.

Wifi not working all a sudden (not showing wifi routers))

The other day i was driving and talking on the phone (i know.. guilty as charged) but then all a sudden my phone hung up.. i loooked down and my signal bars and service was gone.. they werent at the top anymore, its like they just disappeared..
After like 2-3 minutes everything came back up and was running normal (until i got home)
I got home and turned on wifi toggle.. put the phone down and noticed it didnt connect.. I went to wifi settings and the "Turning on WiFI" notification was there.. but nothing after that... it just gets stuck on that or something.
it wont go past that.. Ive tried 5 other roms and the same thing occurred. but on some roms that ive used, when i turned on the wifi, the wifi would be 'checked' but none of the wifi routers would show up..
Its not my router either.. because the colleges wifi doesnt show up on the phone either..
Ive also flashed the latest GB Radio as well.. No luck ..
Any other idea's or suggestions..??
Thanks guys

It wouldn't be the radio. The kernel handles wifi. Are you wiping /system before flashing a ROM?

i was thinkin that

But you can still connect to mobile network, right? How about trying to use your phone as a WiFi hotspot? I believe it runs on the same hardware.
EDIT:
Have you also tried pulling battery for a few mins? I can't explain it but I've done that to fix weird glitches on my phone before.

If wifi is not working hotspot will not work.

That's the point of trying. If hotspot works when WiFi doesn't, it can't be a hardware issue.

True, though the chances are less than slim. Still, troubleshooting means eliminating possibilites. So does hotspot work, or no?

[Q] Moto Defy + call drop straight after dial while in 3G.

The minute I turn on my 3g any normal voice calls made from my phone gets disconnected within a second.
If I switch to Wifi / 2g the issue is solved!
I have tried Settings - Call Settings - Additional settings - Caller ID but the option of caller id itself is unselectable!! I have read many people saying to select caller ID and set network default fixing the problem but on my phone it is unselectable!
Please advice on how I can fix this problem! Thank you

No I am running stock 2.3.6 and havent done any updates since I got my phone 6 months back! The problem is still not resolved!
I beleive it is a problem with my carrier Airtel as they say that there is 3g upgradation going on in my area. But I still face this problem all around Bangalore!! I cant understand what is the major cause of this problem! I have used my sim in my friends Sony Ericsson Arc and there is no issue whatsoever! Im still waiting for a solution. Please lemme know if you find anything as well! Tx

I don't think its a problem with airtel because I'm facing this problem with vodafone, I m facing the same problem with airtel sim also in the same handset however same sims are working fine with other handsets.
Initially vodafone told it might be a problem in their network but after checking they confirmed that there is no issue with their network.
I feel its an issue with phone itself but know its related to hardware or software. Factory reset also didn't work, tried all possible ways that I could think of including replacing sim but no lucktill now.
I took phone to motorola service too, all they could suggest was to replace sim and factory reset which I've already done, only solution left is to give the phone for checking and they need 2 days to check if any fault is there.
Did your phone always had this problem or started recently? Do u remember making any settings in phone before this problem started?

You're right.. I guessed the same! Well this phone has been giving me this problem since January of this yr. Before that it was perfect! I cant remember making any changes in the settings. I have also done a factory reset but the issue isnt solved. I cant understand what to do now?! this really is getting irritating cause every time i have to make a call i switch off the Data using toggles widget and turn on again once done. I cant do this forever. Even the calls which I get from someone else gets cut in a second and appears as a missed call. I desperately need someone to suggest a cure for this!
Do let me know if you have made any setting changes recently . I ll try to remember if there is any common changes we have made and try to find a solution for this.

I also want to state that when my 3g was on before the issue began it used to be displayed as H - meaning high speed internet. Since the day I ve been facing this problem the H symbol changes to 3G - once this transition takes place immediately call gets dropped. I ve never seen the 3G being displayed before the problem.
Question: Does the 3G have to be switched off automatically once a call is made? Like for eg. if you re connected on wifi, even when you are in a call the wifi is still on and active in the background.
Is the 3G supposed to switch off automatically once a call is made just like it does when in 2g??

Some of the things I remember which happened before this problem started are:
1) I updated the firmware.
2) I kept a heavy bag on my phone by mistake.
3) I changed the phone's battery, I'm now using the an extended battery bought from eBay.
4) I changed the screen guard, using a matte finish guard now. (wondering if the solvents that they use while fixing the screen guard have any impact on this)
5) I started using the application Team Viewer a lot to operate my home laptop from office.
I've mentioned everything that I could think of, is any of this matching with you?
Its was a very good handset till this problem started, I don't want to buy a new phone just to fix this problem.
One more thing I observed is that this problem has increased over time, initially when this came to my notice 50% of the calls got cut while using 3g, but now all calls are dropped while using 3g.
The calls - both incoming and outgoing are working fine even if 3g is on but no data is being transfered. Once the call is connected 3g works fine. The problem is only in starting/initiating the call while 3g data transfer is happening once the call is connected 3g is fine.
Regarding my usage:
I've been using this phone very roughly from past one n half year, I use it regularly to download using both wi fi n 3g, I listen to music everyday using bluetooth n also watch many movies on my phone itself.
In short usage is very high n rough.
Could it be a wear n tear damage because of this?
Pls let me know if any of the mentioned points match with you which will help us locate the reason for the problem.

Well Sry but nothing in common! For me since the beginning of the problem, 100% of the calls are getting dropped! its been a month now. Do you face this problem in a specific area or all over town? Ive searched a lotta forums for an answer but to no avail! I dont know if rooting the phone will help!?!?! but that is my next step. Did you try going to Settings<Wifi and Networks<Mobile networks and selecting 3G only? FOr me the problem persists but i guess you should try this.

Hmm, problem is all over the town.
I've also selected 3g only in settings.
Even I'm thinking of rooting my phone but I'm afraid I'll brick my phone.

Same problem
I am EXACTLY facing the same problem. I have an AirTel sim and I don't remember from this problem got started. I tried restoring factory setting, flashing the phone in authorized service center and nothing helped. I was about to install custom ROM and just read this thread in the forum. I will wait for some more time to see if any of you is lucky enough to find a solution for it.
As a temporary workaround, I have changed the GPRS to 2G and its working now. In 3G, if I try making calls, the data connectivity will not be cancelled, but in 2G, as soon as you hit the green button, the data will be cancelled.
Please reply if you find any solution for it. Thank you!

Solved!

1) Does anyone of you NOT use motoblur Account????
2) Does anyone of you NOT use google account in your phone?
I think the solution lies in the questions above. If you use either one, the problem will persist. Try to factory reset your phone and skip log in Motoblur and Skip google account sync. The problem should be solved.

No luck
As suggested by you, I did a factory reset and tried making call without adding Google account and it didn't workout. I had the same problem. I even tried adding another Google account (after wiping data) and same problem. I lost hope
I am gonna use my mobile with 2G only till someone finds a permanent solution.
Thanks for your help!
