VoLTE/WiFi Calling Issues? - T-Mobile Galaxy Note 4 Q&A, Help & Troubleshooting

I picked up the Note 4 last Thursday. This is my first phone with WiFi Calling and VoLTE and so far the experience has been less than ideal. I've found that I get more dropped calls and the person on the other end can often not hear me when we first connect (and I need to call them back) when using WiFi calling or VoLTE.
Is it common to have more frequent call issues with these two features enabled, or could there be an issue with the handset?

I called TMo support last night for similar issues. I would try to clear the cache and data from the phone app. That's what they suggested for me and it's been working much better for me!

Trust me, clearing the cache and data has nothing to do with it. It's a network issue. I've been having similar issues sporadically with WiFi calling ever since they switch to a different format of WiFi calling a few years back. Also couple that with the upgrades they're doing, at times service may be affected.

Yeah I didn't think it would. However, when my calls drop, I get kicked immediately back to the home screen. There was not a FC error or even a call drop tone (which I've NEVER heard on T-Mobile after a call drops). When I had a Note 3 with Verizon, my dialer would say 'No Signal' and it would at least tell me that the call was dropped. I'm not getting that here. After 2 weeks, I can't say I'm particularly impressed with the QoS of T-Mobile as I have several dropped calls daily -- sometimes 4 or 5 per day. It's getting rather old, honestly. If it wasn't for the dev phones, I would have ended up back at Verizon. I just had to start somewhere with the cache and data clear....

Well that's not quite what's happening to me. My calls either drop just like a normal dropped call (sound and all) or stay connected and just have audio issues.
Anyway, I was playing around with it a bit more and it seems to only occur on HD calls. My wife and my dad both have Nexus 5's, and I see the issues frequently with them. But VoLTE calls to non-T-Mobile customers seem to be fine.

Anyone else note 4 take 5 to 10 seconds to connect the call? Happened with my note 3 as well.

Not up to 10, but usually 3-5 seconds. This was true of my Nexus 5 as well though. It tends to be longer when it is not a VoLTE call, I imagine because it needs to drop from LTE to HSPA to connect.

Problem with signal

Hey guys, i have a problem with my signal, sometimes it passes from full signal to 2g, even though I'm in a full 3g covered area, and i lose connection in skype every few minutes while I'm on a video call.
I didn't have the problems before, that started today, i tried to re flash the Rom, hasn't solved it, my only concern that yesterday i have tried to charge the phone with the pogo pins, but instead of putting the - on the - and the + on the +, i have put it the wrong way, and the phone had shutdown, and then nothing happened, just that stupid and annoying problem!!!
is it have something to do with that? how can i fix it???

I'm on O2 UK, this phone probably has the worst signal i've ever experienced. It'll regularly go from 4 bars to "x" (no signal) on and off all through the day, or it will say it has a full signal and my friends tell me they've been trying to call me all day & have sent me texts.
It's got to the point where I'm looking at selling the phone now, as it's fast becoming no use to me. It's not the network, I can sit next to a friend also on O2 UK with an iPhone and they can stream a youtube video, I can't even make an outgoing phone call (just goes BEEP BEEP BEEP and hangs up).
Shame, I love the features of the phone, but its useless if i cant receive phone calls or texts on it.
Its about 2 months old, never been rooted has all updates applied that have appeared (14.1.G.2.257 at the moment) and has had the awful signal problems since day one. If i knew it was going to be so bad I would have returned it, but left it too late (14 day return period)
Never happened at the moment.
Poor Signal
I am also having poor signal problems maybe someone could help with setting ideas??????????

The signal fluctuation is most likely related to the aluminum sides(a reason why T-Mobile went with plastic).

[Q] WiFi Calling - missing calls

Howdy,
I am having a puzzling issue:
WiFi calling is on, I can place calls - no problem. Every day I however am missing incoming calls - the call goes directly to voice mail.
Text messages are coming in from the same number a few seconds later telling me that my wife called and the call went to voice mail
Power cycling the phone or making an outgoing call seems to fix the problem.
It seems to me the trigger for it is when I leave my home and come back. The WiFi calling icon comes up - so it looks like it has registered ...
The same SIM in my "old" Note 2 ... I don't have any issues - no missed calls.
Hardware (phone) has been exchanged, numerous calls to t-mobile with the usual factory reset ... reset phone registration etc.
My internet connection is a directed WiFi ( WISP, I am the owner of the network). I usually have around 40/20 MBit - that should do, IMHO. The slowest ping to google I have seen was 40ms - most the time we are less than 10ms
Any hints are highly welcome ( I am ready to return the phone so frustrated I am ... )
Thanks
Oskar
Well what I have seen is if you stay stock you ended good. Rooting and flashing ROM has giving my phones headaches. I think issues are with TMOBILE handling your phone call switch over. Been on phone with them and have been thru 2 phones and 1 on the way. They don't wanna admit they messed up . so it gonna be a wait till update comes out.

It's a shot in the dark but you might want to try a new SIM card. I was also using a SIM from my Note 2 and was having problems. New SIM seemed to fix it for me. I am rooted as well.

I went through 2 phones also and it's not the sim card because I switched it 2-3 times
I get plenty of missed calls from my work, I wake up and see voicemails and there's no notification of a missed call. So basically people are calling me and I don't even know unless they leave a voicemail which people barely do nowadays.
I talked to a rep and told me to turn off volte and it helped SOMETIMES but it still happens to me.

I have had volte off from day 1. This started happening when they enabled the handoff feature from cell tower call to WiFi calling. It sucks. I want it back the old way.

so, in the moment the conclusion seems to be .. it is either on the t-mo network side or the OS.
One more bit: I am using insteon and Mobilinc Pro for light control. That app works perfect on the note 2, on the note 4 button clicks seems not to work - or at least different.
So I wonder whether it might be possible to flash a note 4 rom to a note2 - just for testing purpose

Check your PM.
I'm glad to see this thread and will be following it. I'm on a T-Mobile Note 3 and am seeing the same thing with missed calls and also repeating and delayed texts. Just today I left my Wifi and got an important text message from about 15 hours ago! I also can't download MMS, but am not sure if it is related yet.
well,
updated to Lolipop and several calls to t-mo tech support and trouble tickets:
I still am missing incoming calls.
When I know a call is coming and I toggle WiFi on the phone on and off ... then the call comes thru
Absolutely frustrating

Start over with screenshots and use a screen record app and show us exactly what you mean. Also what router and model you are using
BAD ASS NOTE 4
Yep this happens to me constantly. Family says "I've been trying to get a hold of you all day" and I'm just replying well it didn't ring so I dunno. And that's on different ROM's.
this is a much acknowledged issue with the LP update, many threads are filled with complaints of it but it doesn't affect everyone so its hard to say the cause. My phone works fine but others' don't so idk

[Q] Silence when answering phone call

I have VoLTE and Wi-Fi Calling turned off. Sometimes when I answer an incoming call quickly (actually that doesn't matter), I just get silence and I can't hear the caller and they can't hear me. I have to hang up and try again; Anyone else encounter this?
Update: I think I narrowed it down. Apparently the first call I receive after rebooting my phone always fails (unless I've made an outgoing call first). Subsequent calls work fine until my phone is powered down or rebooted, then the 1st incoming call fails again. I can reproduce this 100% of the time.
I've had this happen a couple times, funny thing is I've had it happen on my S4 and S5 as well.. Im starting to think its Tmo's network.
It might be a glitch with T-Mobile's network, but I haven't encountered it on previous devices. For example, I just switched from the Nexus 5 and never had a problem with voice calls.
I've had this happen a few times also with my S6. Never happened before, and I've been with T-Mobile for over 2 years.
This only happens for me occasionally if one of the callers is on Wifi calling, but it's happened with every phone (not just the S6) so it's definitely a network issue
I found this related to the S4, http://thedroidguy.com/2013/06/gala...ting-incoming-calls-66029#jMqaFVvIYCDRQHse.97. I've disabled the mute function in motions and gestures. We'll see if that works.

Been with Tmo for 5 years now and I have had this happen on previous devices.. could be the area I am... lol, I also notice a delay when making a call out which I believe is the network
Never had this problem on S4, but since getting the S6 this problem has been bugging me. Very frustrating.

[Q] Dropped Calls

In the last few days I've had at least one dropped call per day on my S6. It doesn't make any difference if my recipient is on a cellphone or landline nor does it matter if I'm in the car on bluetooth or using the handset elsewhere. I did some searches and found others having the same problem, not so much with AT&T (mine) as opposed to Verizon and T-Mobile. Some say a factory reset cured the problem, but I hate to do it unless I have to. Just curious how others on AT&T are faring. My previous S4 never dropped any calls nor did my HTC M7 so I'm thinking it's not a network issue, but something in the phone itself.
I've never had a dropped call in the month I've had the device. I had my chubby cheek hang up on my mom once last week, but that's as close as it gets. My area gets pretty good coverage for att and tmobile though. I've yet to drop a call since joining at&t
My Black Galaxy S6 Edge 64gb module was dropping calls like crazy, and was still within my exchange period so I switched it out. Haven't had any dropped calls since.
Call and connection quality have been stellar for me. Only dropped calls I've had are when going through known dead spots.
Looks like the factory reset fixed it for me so all is good now.

Have you had any dropped calls since your last post here? I'm having dropped calls often. I don't think a factory reset will help me because I wiped all data before flashing the rom I'm running. I may try a factory reset from within the settings menu if you haven't had any dropped calls since the 15th.
I've only had a couple dropped calls since then, but my problem now is that sometimes the other caller can't hear me, specially when I'm driving and on bluetooth through the car audio. It can't be the other caller because they were on a stationary, land-line phone. I checked out my mic by making a voice recording so the mic is fine. I just tried unchecking "Enable HD LTE Services" and I'll see what that does and report back. If it were not for the very nice camera, the annoyance of the dropped and muted calls plus the bad battery life would be enough to make me switch this phone. It's got to be a device-specific bug. My HTC M9 is running Android 5.0.2 and is rock solid and never dropped a call. Same with my LG G3. I would send in my S6 for repair, but I'm not sure what they would do. Not only would I get a refurb back, but it might do the same thing. If you've been following the threads, you might have seen that Sprint had to push a special update for it's S6 customers to fix dropped calls. Verizon customers are also having it bad (I'm on AT&T). It can't be all network issues though as like I said, my other devices including an LG G3 have never dropped a call.
Thanks for the response rmc69. I did uncheck the HD lte and it did not help me at all. Let me know if you have a different result. Thank you
The Sprint S6 and S6 Edge have the same problem. I have to turn off the LTE radio all together to have a usable phone. I couldn't send/receive text, I had dropped calls and a very poor signal. Once I turned the LTE radio off, all those problems went away. I realize this is not a fix but it's a workable bandaid for those that are having problems. Good luck to you guys.
Turning off lte did not work for me.
Robert, how did you turn off LTE? By going into the testing mode and changing it from there? Or were you simply referring to unchecking Enhanced LTE Services?
I think I figured it out from this thread, at least for AT&T

I tried that, it did not work for me.
Sorry turning off LTE still didn't help. I guess the only alternatives now would be to wait for 5.1.1 and see what it fixes, or you may just consider asking for a replacement.

Yeah that is what I'm afraid of. Every time I go to the at&t store it's a big hassle. Hopefully an update will fix our problems.
@rmc69, is your phone rooted and running a custom rom?
No; pure stock. It's also a 64 GB model. I'm wondering if there is a difference that could affect reception, i.e., is the antenna placement exactly the same. I changed my band to GSM Auto last night removing LTE and so far, I haven't had any dropped calls, but it's too early to tell. The biggest problem I'm having is that sometimes callers cannot hear me, especially in the car using bluetooth.
I am rooted running DennisRom. Yesterday I did a factory reset via the stock recovery and made 4 calls and did not have 1 drop. I'll see how it goes for a few days and report back.
Great! That's encouraging.
Bad news, I just called my wife and the call dropped before she could answer her phone. I think I may give up and get a different phone. I'm loosing hope.

Question Terrible Call Quality with longer calls

I keeps coming back and im fed up with it and cant find anything related to this online:
When i make call (in and outcoming 5G/WIFI, doesnt matter) the voice on the other side is just fine. But always after 5/10 minutes in the call the other person starts sounding like a robot and is hardly understandable.
Anyone has similar issues, is it modem related? 5G and wifi coverage are just fine. Let me know what i can try or is this just a hardware failure?
In settings, try toggling adaptive sound and/or adaptive network connectivity. Not a problem for me, though.

Thanks, will try but dont think this will be it though...
I've had this on more than one Android phone, but they were both Pixel's. 3XL and 7. After about 10 minutes the caller would sound tin based, and/or robotic. I thought it was just the line being messed up, but now maybe it's a Pixel thing? Not sure. The times it happened were with a caller that was using VOIP, so I figured it was a mix between the both of us. When I call real landlines, or other mobile carriers, the calls are always crystal clear.

Yes this is the exact thing I encounter. Mostly with a colleague whos on a Samsung and probably also with wifi calling. Never had this issue with all the one pluses I had before the pixel...
Probably wont be Fixed anytime soon since I can't find anything similar online
