[Q] Unable to use wifi while on a call - EVO 4G Q&A, Help & Troubleshooting

Title says it all. When I'm talking on the phone I'm unable to use wifi data. Browsing, apps which require data, maps, nothing workings while on a call.
I am running CM6 stable but this issue has been around for a while that I can remember.
Is there a work around? Could I be doing something wrong?
Thanks

Someone correct me if i'm wrong, but as far as i'm aware you can't use data and calls at the same time unless if your using 4g, which of course MC6 doesn't yet support.

You cannot use 3g data while on a call but I cannot see why you cannot use WIFI while on a call. I will test this on Stock Rooted and let you know in a few minutes.

It must be and issue with CM6 as I am able to make a call and surf the web, access the market, etc.. using WIFI at the same time with stock rooted..

Thanks for the confirmation. I've wondered this as well but I haven't noticed any other CM6 user complain about this issue. Maybe there's something in the settings I need to enable?

Its not cm6 or whatever I am having the same issue. No email or surfing while on the phone and simultaneously connected to wifi. Like the first post "title says it all". I am on Stock sprint rom. Just updated to the 3.70, but this problem has been going on noticably for a week prior maybe longer. I was hoping the update would fix it. Any thoughts? or answer?

You can use wifi whiles on a call to browse internet and use apps that require data. I been doing so since I first got a evo months ago. I only used it on one asop rom and that's cm 6.0 rc2 it worked fine when my gf was annoying me with her boring convo lol so i put on the bluetooth headphones and acted like i was paying attention whiles i was one facebook.

When is the last time you tried? I have been trying to use it on a calls all day, with no luck. Only time Wifi connects is when I hang up.
Scenario a: Wifi is turned off; I initiate call; try to turn on Wifi; Wifi will not connect .
Scenario b: Wifi is on; I initiate call; Wifi will not allow surfing until the phone is hung up.
Also when running speed test while on phone will produce very low speeds less than 64k when my speed should be around 12mbps. Again once phone is hung up the speeds return to normal. The speeds resemble a connection that is being throttled.

Are you connected to a Bluetooth headset while in a call?

Just noticed the blue tooth issue. Thanks for the response, but what gives. Surfing used to work while on bluetooth/phone call. For a while that was my only way to listen to music through my BT headset. I had to initiate a call to voicemail and play Iheart.

Heh, it's hit and miss for me.
What i've discovered is......
-If WiFi and the Bluetooth device are connected before initiating the call, it should work fine.
-Sometimes, the Bluetooth device can be connected later, as long as WiFi is connected to a network before call is initiated.
-You can disconnect the Bluetooth device during a call, turn on speaker [or not] to continue the call, and WiFi will connect, but will probably disconnect when you reconnect the Bluetooth device.
-Using method above, you can sustain WiFi connectivity whilst Bluetooth device is connected if you start to browse a website or launch a data required app such as an IM or online radio app, then while it's in the middle of connecting to one of those, reconnect the Bluetooth device.
Lot of trouble? Hell yes. I'm not sure if this is a problem with HTC's software or a hardware problem with having WiFi/Bluetooth on the same chip.

I was about to post this question up on the Hero forum but I found this thread. I have the same problem. Wifi will connect unless on a call but......sometimes if you are already connected before initiating call wifi will stay on FOR A BIT. After a while, wifi will disconnect on its own and if you are lucky it will reconnect later on. Note this is not alway the case. It ussually stays off. I just dont understand why this happens.

Wifi + Bluetooth + Call = No Internet?

Title pretty much explains it. While on a call, through bluetooth (Voyager Pro+) I have no internet connection via my home Wifi. If I switch to the phone speaker while still on call it works fine. Switch back to bluetooth and instantly problems.
Not sure if its no internet or if it just turns so slow that everything times out. I know while on call without 3g my phone will instantly say network error. On wifi through bluetooth though it just sits there trying to retrieve, eventually saying network error like 5 minutes later

Incoming callson WiFi calling goes straight to Voicemail

I love the phone and having the hardest time resisting turning the phone back in. I'm on my 2nd S3 and my third Sim card. Everything appears to be going well but I noticed that when my phone is in WiFi calling mode, incoming calls go straight to voice mail. I don't get an alert or anything. If they leave a voicemail, I get that. I searched other phones that have had this issue not just the S3. I am running stock OS but I am rooted.
Can anyone else verify that there incoming calls are working on Wifi Calling ? Any ideas on what I could try ? outgoing calls work fine.
EDIT: Sometimes calls go through, sometimes it doesn't. When it does go through, I can't swipe the green button to answer. It goes through the swipe motion but nothing happens. When I am off of WiFi calling, I can receive calls correctly and I can properly swipe to answer them

Ah-ha, you just solved a mystery for me! I like to have my phone automatically connect to any wifi in my usual hangouts to save data. I kept wondering why I was missing calls without hearing my ringtone. I have a theory on what is happening. Back on my old Vibrant, wifi-calling could not work on slower networks. I could get it to initialize but never could it actually make a call. I noticed this when up in the mountains at a lodge that had very slow internet. Maybe it's the same issue? Hopefully others will chime in.
Not sure if this a slow network issue or and ICS issue. My S3 does this also and is frustrating since I auto connect to wifi at home and work. Keep missing damn calls. My S2 started doing the same thing when I updated from GB to ICS. Maybe its a Samsung and ICS thing now that I think about it because the wife and kids all run ICS on HTC Amaze without issue.

Disappointing. Are you on T-mobile? (I expect yes as this, to my understanding, is the only US network licensed to use wifi calling?)

I think most of these threads are locked because XDA is trying to separate them all. Anyways, this is the only way I could respond. Since my first post, I have had more positive experiences with wifi-calling. I think it may be a little of both, slow connection and this newer implementation. On a slow connection it definitely wont work correctly which is what I would expect. What I mean is you can't successfully answer or make a call as the phone app will just hang. Going straight to Voicemail is another mystery altogether. I have 4g internet at home so there is no reason I can think of for that to happen. But like I said since my first post I have successfully made and answered several calls from home using wifi-calling and even a few from a location that had decent internet. Call quality was decent for what it is.
Guys, take a look at this thread. It concerns wifi signal dropping and re-enabling. That would certainly explain why some of the calls made to me when I was at home on wifi went to Voicemail even though I have 4g. I did notice some of this last week.

This happens on sprint phones as well...
I see this thread is open again. My experiences with wifi-calling have bore out what I thought: A weak signal will cause problems. I only wish that every call went to voicemail. What happens often with me is that wifi-calling will partially work, as in I can answer a call but the person can't hear me at all and I may catch one or two words from them. If they terminate the call, the phone app is fine, but if I terminate the call, the phone app hangs and freezes everything! Today it was so bad I had to pull the battery and reboot. Maybe wifi calls going to voicemail is an imperfect function that Samsung or rather T-Mobile built into the app. It kinda makes sense as this app could never complete a wifi call if you were connected to slow internet when it was a separate app. In any case I would rather have my wifi calls go straight to voicemail (and get a pop-up notification) than have the app try to work but wind up hanging my phone. What do you guys think?
I don't know about slow networks. I've already exchanged one T-Mobile S III because of Wi-Fi calling problems. My replacement works much better on my work network than it does on my home network and it is much, much slower than my home network is.

This isn't particularly good news for me. If it isn't software problem that manifests when coupled with a slow network then a future update won't fix it. That's what I was hoping the problem would turn out to be. If its hardware, then the time I have to do something about it is limited as I dropped my first phone and the replacement has a limited warranty, I think. Plus, I've paid to have invisi-shield placed on the front and back and would have to eat that cost if I get another replacement.
Epic Fail
I have this issue and am at my wits end to resolve it. Wifi calling is a major feature that worked fine(except echo) with my Vibrant. However, nothing I have tried will fix my ability to answer calls on WiFi. I have the SIM from the GS3 box. My E911 address exists since my bb8900. WiFi Power Save is off. All routers I use, Linksys E4200 and Linksys WNR1000, Linksys 614. Wireless N and G. T-mo CS could not help. I understand that the WiFi calling changed from UMA to IMS. No separate app. GS2 users with same issue. Anyone with a clue? Please help.

how did you turn off the wifi power save?
I experience the bad quality calls on wifi, at my workplace it is perfect, but at my home, its terrible.
my home network is faster than my workplace.
I think this is something to do with the firewall as well.
and I couldn't find the way to turn off firewall on the dam verizon fios actionnet router.

you can also try to broadcast the wifi on channel 3 only, that helped me in my case.
WPSM
There is a link earlier in this thread to another XDA thread. Phone app --> *#0011# --> menu button --> WiFi--> Press WPSM On/Off button.
My GS3 would drop a WiFi signal 3 inches from the router at work and 3 feet from the router at home. At least THAT is fixed now. However, I don't seem to get the same WiFi signal range as my Vibrant did using the same routers Trying the channel 3. I do have a few setting set to auto at least on my home router.

Yes, that's required, but not the underlying issue of the thread.
I've had wifi calling weirdness too. I called my sisters Verizon cell and there was no tone but after xx seconds it got her voicemail. When I call my phone on my house phone (Comcast) my phone rings but there's no tone on the house phone!
I NEVER get a ring. Just someone picks up our voicemail does.

[Q] Wifi Calling working but Off Under More Networks (Answered)

Hello,
I've found out that my wifi calling is being used even though I have it off in the settings of the phone. Although it's off I still can select the options under Connection Preferences: Wifi Perfered, Cellular Networkin Prefered and Never use Cell Network (not sure if that matters or not). I choose the 2nd option and noticed dropped calls around the outer edge of my wifi. But wifi calling is turned off. How do you permanently turn this feature off?
I do use wifi when I'm within my wifi area. But had no idea that wifi calling was still being used when set to off. Do I have to disable wifi all together?
Ok. I've found out that this is known issue doing more a search online. The only fix is to disable wifi altogether. There have been other suggestions but none of them fix it. I've heard that exchanging the sim chip that disables wifi calling might work but haven't heard anything consistent with that fix.
I'm just perplexed by this. This is a great phone yet whenever you enable wifi you enable wifi calling regardless if it's off. I just don't get how something like this would be considered a standard feature when other phones just don't do that by default. If I didn't stumble upon this information I would have never guessed that it was the main cause for my dropped calls.
Thanks about that update it could help others soon.
NP, I have to wonder if this is really a standard none controllable feature on the phone or if the carrier can disable it?. If wifi calling is controllable on the phone and you can turn it on or off jet remain on then I have to wonder what other external force is keeping it on when you turn it off?
Did the maker just simply forget to remove the ability to control wifi calling because turning it off simply doesn't work.
or
Is this something that the carrier did
or
Is this something with the sim chip
Another thing I've found that seems to be related to this. If you try to access your acct while Wifi is enabled it suppose to switch from wifi to 4G but it doesn't (and you can't access your account in tmo. while in wifi. Perhaps different software updates were used but it was seamless back then on a different phone.
This brings up another interesting observation. Once wifi is enabled you can't auto enable your 4g network when it's needed. IE: You can't review your acct for one. Is there a way to make sure that your phone has 4G LTE priority whenever wifi is enabled?
I don't know also how to prioritize the 4G LTE over wifi, good observation.

Update, I was able to use an old version of my account (which was used on an older phone) and was able to confirm that it is programed to disable wifi connection and activate the 4g services while using the my acct app without having to disable wifi manually. A message even popped up to tell you so. And once you exited the my acct app it would restore your wifi connection from 4g. So it is controlled via the program itself.
So it begs the question, why doesn't the newer version not do this? This now looks like 2 separate issues with wifi and wifi calling.
Verify if Wifi Calling is still enabled even though you have it disabled
I just found a way to verify if wifi calling is still enabled even though you have it disabled on the Note 3. Here is what you need to do.
1. Make sure that wifi calling is disabled
2. Make sure that wifi is already enabled and in use
3. Stand right next to your wifi router
4. Make a call
5. Listen to hear any wired sounding ringback (the sound you hear to let you know that a call is actually ringing the recipients phone).
6. If you do notice a wired sounding ringback complete the call and stay on the line for about 30 seconds or so.
7. Disable wifi while on the call.
8. Once disabled did your call drop?
This is what I did in order to verify if wifi calling is still enabled even though I have it disabled on my phone.
I'm not going to say it's happening to every one. Nor would I suggest it's a bad feature for those who need wifi calling. I just don't understand why I'm forced to use wifi calling when I fully capable of using my 4g network.

That is weird. I tried your steps, I couldn't recreate the problem. Just to make sure, I was talking about the phone network signal, not Wifi signal.
If the bars were becoming 0, there is a fix. But otherwise, it may be a faulty unit. You can try and get it replaced.
BTW, try this and see if it helps: http://forum.xda-developers.com/showthread.php?t=2698329
Thanks man! Gonna try this
Rahulisola, thanks for the link. I was able to fix the issue by doing a factory reset. Not sure what caused it but now I can disable wifi and the call stays connected. Although I found it odd that wifi calling was forced enabled during the reset while I was setting up the wifi network. Disabling it after the factory reset setup did prove it was really off this time. I also noticed that I'm not seeing "HD Voice" which I know assume is related to wifi calling. As I've seen HD Voice whenever I was within my wifi range during a call.
Also, Lorettaa thanks for looking into this as well. I really don't know what caused the problem but I'm glad it's fixed now . No more of pitched ring backs while making a call. And no more odd echo voices when talking. And most importantly no dropped calls.

Glad that it is solved. Usually I always do factory reset 1st and ask anyone with problems to do that too. My bad, I assumed you had already done it. Must be some other thread. Too much work catching up on me

WiFi Calling dropping calls...

Ok, it seems for me the issue with wifi calling not working at all is resolved (I always have the "Wifi calling is ready!" notification) but when I receive a WiFi call it will randomly disconnect after a few minutes. Might be 5 min, might be 20, and after that if I or they call back it might disconnect in as little as 2-3 minutes! Doesn't seem to matter if I answer on my handset or my GearS, still always drops in <20 min.
It's not my internet connection dropping, I also have Skype with In/Out running and can place/receive calls on it without any interruptions (on both my N4 and my PC).
Any suggestions?
Phone is 100% stock, not rooted, Android 4.4.4.
Wi-Fi calling was a PITA on KitKat with my Netgear router. Netgear support and DD-WRT forums for my router were both saying to disable the firewall. Forward porting and setting my phone as DMZ with static address didn't help with UDP packets and maintaining a connection.
Lollipop its better and the reason I'm not going back to KitKat but hardly tolerable without root.
I know this doesn't apply to you but with Adaway, I monitored the DNS requests for Wi-Fi calling and whitelisted them. That seemed to help with the Wi-Fi connection list issues. There's webservicesgateway and vowifi dns requests to look for. Didn't post for security concerns.
Yeah, I'm scared to make the jump to lollipop because right now my GearS is working perfectly and I'm scared to change anything major (spent 2 weeks fighting in on the "compatible" SGN2, finally said "screw it, I'm due for an upgrade" and got the SGN4) as Is aid I've not even rooted my SGN4 for fear of 'breaking' my smartwatch...
Router could be the issue, since it's a brand I've never heard of before ("ComTrend") but It's a router/modem combination that my ISP requires so I cant swap it out... may try the suggestions you mentioned, just in case, but not going to hold my breath...
If anyone else has suggestions, please post them. Right now I'm in a situation where I need VoIP (I literally get 0-1 bars reception, so bad that if I answer a call it drops) and to get Skype to work I have to turn off calls comming to my handset (otherwise the Phone App overtakes skype, then drops the instant I answer) which means I miss calls when NOT at home thanks to skype playing poorly with my cellular data... >.<
Off topic: did you consider asking Sprint for an Airave unit? Bad cell signal.
Mine was free to use and got exchanged/upgraded for newer model a couple of times.
I let mine go with Wi-Fi calling because it conflicts. Had to pick one.
I've had two actually. Back when it was amde by Samsung it worked GREAT, (thought they charged me soemthing like $5/month for it) but now the new "Airvana" version has stopped getting a GPS signal... why I cant program it in I dont get (since WiFi calling works with out constant GPS) It's been sitting around gathering dust for a while, I might get it out and try to make it work again, maybe they upgraded their system enough that it wont turn off... or maybe I'll try sticking it in the attic or something... thanks for the suggestion!

T-Mobile WiFi v6.0.1

I'm having problems with WiFi calling since the upgrade and could use some help. Prior to 6.0.1, I would be able to see the phone was connected to T-Mobile for WiFi calling but since the upgrade, even though I'm connected to WiFi, the phone won't connect to T-Mobile WiFi calling. It doesn't ring or received SMS. There are rare times it will connect, but for the most part, it doesn't.
Any ideas?

Reboot? On mine I've had times when wifi calling just seemed to refuse to connect. Rebooting usually got it working again. Not sure if I've seen this since 6.0.1 but definitely prior.

Yea, but that seems to be a temporary fix. It will lose the connection again. Frustrating.
this may sound dumb, but did Wifi Calling get turned off during the upgrade? May be worth checking (unless you already have, then I'll just shut up!)
I'm on 6.0.1 and use t-mobile wifi calling for the majority of my calls without issue.

It is on, Cellular preferred. I had it on wifi preferred but the call quality anytime on wifi isn't good enough. It will connect but then loses the connection at some point.
