data connection drop during call

hello all,
i use HOX mainly for call, text, email, camera and hotspot tethering. basically i can use HOX for all this purposes greatly except for wifi tethering / hotspot. this is because when i start the hotspot and connect my pc to it, data connection will drop immediately if i make a call or someone call me (im not even answer the call). you can test your self by disconnect your network from wifi so that data connection with 3g/H/E/g will show up on notification bar. and then just call anybody.. you can see the 3g/H/E/g will disappear from notification bar..
if someone had solution for this please let me know. i already search and found that the solution is to set the network mode to "WCDMA only". choose "GSM / WCDMA auto" will definitely trigger the issue. but this solution is not practical for me as coverage here is not great to choose "WCDMA only".
for information i have no issue with this on my previous htc desire and galaxy s2.. even worst, i can usb tethering and make a call on my ancient SE K810i.. i know htc one x had so many issue and some of it also bug me.. but i still can live with it.. but to not make/receive a call during wifi tethering is already too much.. i dont know what should i say..
can some one please help me on this???

DTM (Dual Transfer Mode - the ability for voice and data services to run concurrently) was removed by HTC in a previous update... I think it was 1.28.
It is therefore normal behaviour now.

any idea why would HTC remove it?

I have no idea. A guess would be that it possibly caused an issue elsewhere, or maybe it was a battery life thing. I'm just guessing though.

You can modify this in build.prop
ro.ril.enable.dtm = 1
If i remember correctly. Do some additional research but i think you carrier has to support it

I'm on 1.29 (via RUU) in the UK on Orange. While connected to 3G or H I can still make and receive calls while keeping the data connection, I just tested it. If they removed it in 1.28 maybe they put it back in 1.29, or maybe it's to do with network provider?

Your connection is HSDPA which is not affected. Only 3G (GSM only mode) is affected.
In other words, instead of H, you will see G. DUring that time, if you are in a call and at the same time you trigger data transmission, you may have dropped calls.

Ah, well I thought that was the norm anyway. I've never been able to keep a data connection on either G or E networks on any handset, only on 3G or H.

thanks for the answer.. but to tell you the truth, i really noob in rooting.. dunno where to start to read.. plus im worried if im doing it wrong.. so for now.. might wait for update if there is changes on this.. however.. as backup plan.. i will try to read about rooting this phone.. (still dunno where to start) hehehe

Maybe...
Use power saver settings from play store.
Uncheck all options and reboot. Does not require root and adds missing options HTC left out from ICS. This fixed both my unreliable data and WiFi issues.

I thought it was normal on all phones not to be able to get a data connection AND voice call over GPRS or EDGE at the same time on any handset?

My mistake, I should of known this but got mistaken.
Just remember my old Nokia 6230 on O2(uk) would always put the data 'call' on hold while receiving an incoming call.
S.

can i know if update 1.29.xxx.11 did something good on this issue? I'm tired of keep reconnect to hotspot when some one call me.. or some will not able to call me at all during hotspot is on.. i work in IT field which require me to connect to VPN, citrix and server..keep reconnecting due to connection down make me tense. i tried to avoid root for now because i just dont want to screw up my warranty.

[Q] Anyone else have Wifi received calls drop after 1:26

Has anyone else noticed that received wifi calls drop after exactly 1 minute 26 seconds? Outbound calls don't seem to have the problem, only inbound. I thought I was crazy at first, but it seems others are experiencing the same behavior. If you Google "t-mobile galaxy note 3 1:26", the first result is a posting on the T-Mobile support site reporting exactly this problem. From that posting, it appears that this does not happen on T-Mo to T-Mo calls. So far, I can reproduce this problem 100% of the time and it is always exactly 1:26.
I have called into T-Mobile and started a trouble ticket and should hear back in a day or two, but I wanted to see if this is a universal problem with Note 3/T-Mo and the best place I could think of to check on that was XDA.
Please test when possible and respond if you are also experiencing this issue.
Thank you!

FYI note 3 users, WIFI signal is not stable in Note 3....

Agreed. I keep getting WiFi disconnects and a message pop up saying my WiFi connection is unstable. Wrong. My WiFi is fine and works on all my other devices just great. I have LTE at home and unlimited data so I don't even turn WiFi on anymore.

I'm not getting any messages about wifi being unstable. It's been working very well. It is only on received calls when in Wifi Calling mode. The calls drop after exactly 1:26, every time. The post on the T-Mobile support site has added 2-3 more people who are having the same problem. Can't seem to find a commonality among the the affected except that it is always 1:26, always on inbound wifi calling calls from non-T-Mobile numbers, and seems to only happen in this way on the T-Mobile Note 3.
If anyone could give it a test, I would appreciate it. Just call your Note 3 from a non-T-Mobile device while in Wifi calling mode and see how long it takes to drop the call (if it does at all).

I just had this happen to me today at work. Three incoming calls from my wife, all dropped at 1:25, 1:26, 1:27.
I'm wondering if this is only on stock ROM's. I'm rooted and don't remember having this issue before rooting.
I wonder if a custom ROM will help... ;o) Not that I really need another reason to try one.

I also have the issue with the dropped wifi calls, I know its not my network as my S4 works perfectly

I noticed some wifi calling issues. I wasn't that it was dropping at a specific time though. I would dial the number and it would sit there doing nothing. It wasn't stock either. I was on MyRom. Strange. Wifi signal is great btw.

need this shiz fixed
link to T-mobile thread?
did you ever hear anything back?

My house has horrible signal so I rely on the wifi calling so yes this issue needs to be resolved asap

I am having dropped calls not only with wifi calling but also with regular calls.

Tmo rep rold me there is an update coming soon to address the wifi calling issues. Not sure if she was being truthful but that what she said.
N3 anticipating Tweaked perfection

I have this issue as well. Seems others have narrowed down its circumstances.

This is so frustrating & we have yet to get a fix.

I have the same issue expect my carrier is verizon.

I haven't had any issue with wifi connection, even when the call drops it stays connected, its just that it disconnects.
I've noticed frequent random disconnects on t-mobile to t-mobile wifi calling as well but not as easily time-able.

Any updates?
Anyone have an progress on this?
I have the same problem as everyone else. 1:26 every incoming call. Bam... dropped.
Very frustrating, especially with how reliable it was on the S4.
Anyway, hopefully we'll see a fix in the first T-Mobile update.
I've also subscribed to the T-Mobile thread, though I expect this thread to be my first answer...

Same here and another co worker with the note 3 is having the same issues, opened a support ticket with tmobile so lets see where it goes ...nowhere more than likely
---------- Post added at 12:00 PM ---------- Previous post was at 11:30 AM ----------
So after some testing im finding when using google voice number the calls will drop. When i get called on my tmobile number on either wifi or cell the call is solid, but if it comes through the google voice number it will drop every time.

MMS + WiFi Calling - Show Off Your Knowledge Here!!;)

MMS is so unreliable over WiFi Calling mode. When I connect to WiFi, I keep getting a toast message saying "Access has been Restricted" and I can send SMS but can't send any kind of MMS...even with the stupid stock messenger I can't either
T-Mobile is stressing me out. I've had Verizon for 10 years up until last Saturday I'm stumped.
T-Mobile's WiFi Calling uses something called GBA Authentication which is only supposed to allow access to system apps and apps digitally signed by T-mobile.
GBA Authentication?? How can I trick this feature into thinking it IS digitally signed? Or whatever I need to do. Help?

OK this is what I know. SMS and MMS over WiFi needs a special set up on their end. It gonna be hard for you to find someone to know what they doing. Took me over 30 + calls to them. I would keep calling and have them escalate to higher tier tech

Yeah, I'm just wondering if the latest OTA fixes this…some research I just did talks about the most significant fix in the OTA is for MMS failure and WiFi Calling mode.
Are you able to test this out? I need to know if while having wifi calling enabled, mobile data DISABLED and wifi enabled, can you send yourself a picture thru text (MMS)?
Anyone?

REALLY??? Damn, i need that to work...i get NO service in my house...only WiFi. Really hoping this OTA fixes that. Thanks bud.

I do not use the stock app, I use hangouts, but even with the update MMS isn't coming through. I get a message that I have 24 hours to download them and can only do it on cellular.

It's very unreliable, will only work with the stock messaging app and only sometimes for me

MMS over WiFi will NEVER work with any messaging apps other than LG stock because the stock app hooks into the proprietary IMS framework that allows SMS/MMS to go over T-Mobile's WiFi Calling servers instead of the cellular network.
Third party developers do not have access to the IMS framework, so other messaging apps will NEVER be able to send SMS/MMS over WiFi.
That said, SMS/MMS works for me perfectly with the stock LG messaging apps over WiFi.

MMS doesn't work for me with the stock app either. FULL WiFi too. So freaking annoying! Switched to T-mobile last week...worst technical choice I've made in years. You get what you pay for WTF, and not just cuz of this either. This is just typical icing on the cake.

Not true about SMS not working over wifi with 3rd party app. I can say at least THAT works

It's probably sending it over cellular without your knowledge. Check your signal bars when you're trying to send the SMS over WiFi, they should be blank. Or go into Airplane Mode, then turn just WiFi on and try.

Airplane mode stops the phone from activating WiFi calling. But with a blank signal bar and a double check in the network section of the settings reading signal off, 3rd party apps will send text over WiFi, just not mms.

Yes, WiFi calling is enabled. I have great internet and a $200 Asus router which is nothing but awesome. No matter which router I connect to, I can almost never send MMS via stock messenger. I have no signal bars while connected to my router. Especially when I'm home, I get no mobile signal as it is
Which Network Mode are u guys on?

BAD ASS G3

I can confirm on Wi-Fi calling, with the Wi-Fi calling symbol on my task bar and my cell signal icon all greyed out, I CAN and DO get SMS through hangouts. No MMS though, I get the "failed to download message.

Mms dont work with wifi calling only works in stock messaging app

Cannot make or recieve calls after lollipop advanced calling activated.

I did not find anything in my verizon to activate so I simply turned on the feature with my phone and lost ability to call.
To make a long story short, after pulling Sim card, battery, clearing cache, partition cache etc I still could not make or recieve calls on my verizon note 4.
After activating the advanced calling feature, it asks you to wait about 5 min and reboot.
I waited about 20 min and lost my ability to do calls afterwards. Even after turning off the feature I still could not get or send calls.
Here's what fixed it..
1. Turn off advanced calling feature in the phone.
2. Then reboot
3. After that you can turn it on or off and calling is restored.
Just wanted to share as I could find no help online.

Turned it on after the upgrade a couple days ago. Works for me. Get a little "HD" icon on calls and the video button. Haven't tried video, and don't notice a difference in call quality yet. But I've not made many calls and even few to other verizon users.

Seems the voice is still dependent upon the regular voice channel bring intact.
I was on hospital wifi and recieved a call but the call still dropped when walking deeper into the building where 4g was lost. Point being it did not handshake over to wifi.
I think only video does that.
But all of my calls have been good, but like you, I can't tell if a real change yet or placebo.

I noticed on my Note 4, the stock dialer keypad has the video call icon grayed out. Is this correct? I was able to receive a HD call as well as a video call.

Seems it is greyed out until the other party actually connects then it checks their status and only then are you allowed to push the icon button and it will tell you if the party is not a candidate
Even when the icon becomes active is still appears grayed out, maybe it only turns color once a connection is made you do the HD service?

Not particularly intuitive. I'm not sure how I initiate a video call if the icon is greyed out. The video call I got was a test from a Verizon store employee testing the system. He wasn't all that sure about the feature. However, once I received his call, I can use Recent. There is a video icon available in this screen. But, the keypad video icon stayed greyed out even if I manually typed his phone number. Non-intuitive.

well it was practically quite funny when I called Verizon tech support and I got a level 2 tech. I ended up solving my own problem and teaching her the whole time, she asked me if my phone was damaged because she couldn't retrieve any information off of it.... of course I neglected to tell her I had all of that stuff blocked!

To me had dangerous situation. Couldn't get call in my house as my 4g signal is iffy (cell signal fine).... HD voice doesn't automatically swap to old cell towers if no 4g. Not good for people who rely on cell phones for jobs at hospital

That must mean it's activated... Or it would be available.
My next screen shows checked as here...
But still trying to confirm it's actually working... Guess I'll never know till I connect with someone else that has it?

I have a similar problem. Making calls seems to work OK, but anytime someone calls me it is just dead air. I have tried toggling HD voice on and off, restarting the phone, and popping the battery out and removing the SIM, etc. Nothing seems to work.

Mine looks exactly like your screenshots. I also was able to test both HD calling and video calling with a relative who has a Note 4 as well. I couldnt really notice a difference with HD calling since we both were using BT but the HD icon was on during the call then we switched to video calling and it worked without any problems.

Did you try the sequence that fixed mine in post #1?
Turn off the feature. Then reboot and let your system reconnect to the network while the feature is off.
Then turn it back on.
Seems once you activate the feature the first time and the switch is turned on for you in the network it needs to connect to your phone while the feature is off... Once connected, it stays connected when the feature is turned back on.
Once you're past this phase, seems you can turn it off and on at will without issues.

I tried that. I even did a factory reset with no luck. So basically I did a factory reset for no reason. I went into My Verizon and removed the feature from my account entirely and it seems to work fine now.

Strange.. I never went into my verizon at all... Correction, I did look but couldn't find the option so I just activated it only on my phone.
I had Verizon check and they said they show it activated.
They definitely have a few bugs yet getting set up.

Seems the voice is still dependent upon the regular voice channel bring intact.
I was on hospital wifi and recieved a call but the call still dropped when walking deeper into the building where 4g was lost. Point being it did not handshake over to wifi.
I think only video does that.
But all of my calls have been good, but like you, I can't tell if a real change yet or placebo.

Calls will not work on WiFi since Verizon has not enabled this feature yet citing there network is good enough where they don't need to rely on WiFi.......that's literally what they said. Advanced calling strictly enables VOLTE which is voice over LTE as opposed to over their old 3G CDMA network. Also allows for native video chat which also uses LTE. They said WiFi calling is planned but not a priority.

If they let you do WiFi calling they wouldn't get to sell the network extenders at an outrageous price. They get no benefit out of allowing WiFi calling.
Edit: bastards.

I turned on Advanced Calling on my Note 4 and haven't had a problem. However, I tried turning it on on my wife's LG G3 and she had the same issue. She could make or receive any calls, but could send and receive texts. It took a while playing around with it, but I finally got turned it off and it's fine now. Not sure why her's won't work.

Try Netflix over wifi, any issues?

Just recieved my G4 from T-Mobile. Factory fresh device here. When using the Netflix app while on wifi im recieving problems. Basically sometimes doesnt log me on at all. Then when i do switch to cellular data, it then works. Also the videos take longer then usual to start if it does start at all. I have the Note 4 right beside me connected to the same wifi, works without a problem. I did factory reset again to eliminate singular instances. Doesnt seem to effect the outcome. Anyone else with similar problems??

No issues for me on my Verizon G4 on Wi-Fi.

No issues for my tmo variant.
Does this issue replicate on other Wi-Fi networks as well?

I haven't used Netflix long on the G4 but when I was checking it out it seemed 100% fine. Logged in superfast and playback as well. I did testing vs my Note 2 and the G4 blew it away how fast everything was loading etc.

I had to turn off Wi-fi calling. I couldn't sign into Netflix with it on. Netflix is working fine for me with it off.

Sounds like a QOS issue on the router.

Not likely, in my case at least. The router in question is an ASUS RT-N16 running a Tomato variant with QoS rules that have been working flawlessly for me for two years. In addition, I wasn't even using Wifi calling, it was simply enabled. My N5, N7, and Galaxy S2 have no problems signing in. The error I received had to do with the network time. As soon as I disabled Wifi calling, the error resolved.

Turning off wifi calling worked. Thanks for the advice.

So after getting the replacement G4 in store my Netflix not working either without Wifi calling off. The old phone was able to play back fine with it on. Can anything else be tried. Since Wifi calling is a feature I use at my house since we have bad signal area and only use Netflix on Wifi so they both need to be working. I tried everything from Netflix chat will try a modem/router reboot again.
I did another factory reset and only connected the 5G wireless signal (thought maybe that was the issue) it worked right away but once google service updated again thats it wont work without Wifi calling off so...
Anyone other Tmobile users can test this or Netflix and say if they need to have Wifi Calling off or not ?
I do believe it's something with the Google Service update since I tried it again same issue. I did find out you don't have to turn Wifi Calling off but change it to Cellular Network Preferred instead of Wifi Preferred. It does work if you change it back to Wifi sometimes but only if the video is preloaded but it's hit or miss if it works but if you play another video you will have to change it back to Cell or Off.

WiFi + "WiFi Calling" + NetFlix does not work
I had the same problem with my new "LG G4" phone. If connected to WiFi and the "Wi-Fi Calling" feature is enabled then I get these NetFlix app errors:
- Please make sure that your device has network connectivity and the Date and Time settings are acurate (-3)
or
- Sorry, we could not reach the Netflix service. Please try again later. If the problem persists, please visit the Netflix website (12001).
I tested on multiple very high quality WiFi networks.
The workaround was to:
- Disable "Wi-Fi Calling" when using WiFi and NetFlix
or
- Don't use WiFi, instead use T-Mobile's cellular data network

Thanks but look @ Sfkn2 post at the top member is with Tmobile and said no problems. I replied around that time no issues but now I have the problems. Yes those are the errors.
Someone is to blame and they all just want to point fingers at each other. It's on Tmobile to fix this and that probably won't happen.

Right. Apparently I can't take a screen shot for you guys to see while the movie is playing. But you can see I'm connected to WiFi calling on tmo network..

Yes that's what strange that I had 1 of them working on it but both don't now unless I change to Cellular Network Preferred . Can you tell me if your on a 5GHz or 2.4GHz connection or if both work and then your Router model. The connection shouldn't matter much since I had it working on both and found the 5GHz was strong enough to use in most my house and was using that most of the times. Might try changing the channels or something.
I have the Asus RT-AC68U (not the Tmobile one) I bought this just after release.
Streaming to my phone using the Emby app from my Emby server works fine as well.
I know we have a work around to atleast Stream but need to get this sent to the right places for a fix.

Netgear N600 - model WNDR3400V3.
Makes no difference whether it's 2.4 or 5. Dynamic IP setting. QOS option is off.

I posted the issue over at http://www.reddit.com/r/tmobile/comments/3bedec/lg_g4_netflix_not_working_with_wifi_calling/ and got a response from a Tmobile Employee which I believe is on the Engineering side. They are going to report the issue so it's a start to see if they can fix it.
