Accepting calls when in 4G mode - Huawei Ascend P7

I'm having some issues receiving phone calls when I'm in 4G mode - I'm aware of the fact that voice over lte doesn't work yet, however in my understanding the phone should quickly switch to 3g mode and accept the incoming call, right?
Apparently my P7-L10 has trouble with that. It just doesn't switch, and the incoming call goes to voicemail.
Is that normal? Is there any fix to make the device switch to 3g mode quicker upon a call?
Running B135 rom, rooted.

I'm having fine calls when I'm on 4G. (Milan, north Italy). Perhaps your city has too few 4G antennas and doesn't have stable 4G signal so it switches back and forth to 3G while you're having a call?

I don't think that's the issue, 4G coverage here is pretty amazing.

Forget what I wrote, I forgot that voice calls don't have to do anything with LTE, lol.
Anyway I'm having fine calls with 3G or 2G, have you tried doing a nandroid backup and start over to see if the problem occurs also in fresh state?

Fine calls with 3g or 2g here as well.
Except when I'm on 4G - nobody can reach me, it all goes to voicemail...
I could say I started fresh - I did a factory reset and a clean wipe 3 days ago, but I haven't noticed the issue untill yesterday.

On a French, people reported issues with calls in 4g covered area, but it seems that the problems come from network, not from the phone. The issues appear only in certain areas with one operator, and some other phones behave in same manner. Perhaps you need to check with another SIM card from another operator.

hello,
I encounter the same problem receiving my incoming calls in automatic mode 4G 3G 2G redirected my mail. When I'm on automatic 3G2G no problem.
I'm B133 update. 4 months no problem. Since mid-October the problem occurred.
My operator is Virgin Mobile. P7 smartphones, antennas or operator?
The rocker 4G 3G to receive calls no longer made. Tried my sim card on a S5 and a LG G2 and the problem is the same.
After several calls to my operator solution but not another concern, I have to connect data to receive my calls 4G 3G 2G automatic.
I'll try to go B121 update or réinisilisation P7.
If no solution change operator before trying their sim card lent by friends subscribers home.

Froyo turns of 3G when on Wifi

As the title says, when my Nexus One is connected to a Wifi network it turns off 3G. Which makes since to save battery. I'm in Japan, and use Softbank as my carrier. Softbank does not use 2G for voice, but only 3G for voice and HSPA(+) for data.
So I am unable to receive voice calls while on Wifi...I thought about using Google Voice as a workaround but it still does not support re-routing non-U.S. phone numbers.
Any ideas? I hope custom ROMS such as Cyanogenmod fix this.
Thanks,
Brandon

WOW that stinks. i think that the best thing todo is wait for the source being released and than make a request.
I get 3g when I'm on wifi...
Change your phone settings to WCDMA only.
*#*#4636#*#*
it doesnt turn 3g off, it just removes the 3g icon from next to your signal meter. but you still have hsdpa connection if you go into settings and check. is this what you mean?
uhhh that doesnt sound right... you should still have your 3g voice connection even on wifi...
Yes, the 3G icon goes away when connected to WiFi.
I just tried it again, and it worked. I don't know why it didnt the other times I tried to call from it, and tried calling to the phone,
Thanks

Milestone CM 6.1.2-12 missed calls

I have had few missed calls where the phone was not ringing at all, later got a text message from my operator I missed a call.
It has happened few times, first I thought could be lack of service. Later I have done some 'research' and found out the missed calls happen always when I use 2G(EDGE) network at the moment the call happens. Just loading page by the browser or browsing XDA is enough.
Important, it is not enough to have the data transmition enabled, the transfer must happening right before and/or at the moment of the call.
The caller gots a message from the operator that the phone is not registered.
Anyone with similar issue?
EDIT:
When using 3G I can't reproduce, I stay with 2G enabled all the time as it uses much less battery than 3G ...

its not possible to use dataconnection AND phonecall in 2g simultaneously! it is normal that when a data connection in 2g is active, no calls can be processed - but 3g has no problem with that. there is no coherence between this "bug" and CM 6.1.2.0.12 or any other rom. you can try other roms, but in 2g it will fail due to provider support

Q: Simultaneous Data and Voice on T-mobile HTC one

HI everyone --- just picked up my phone tonight from tmobile. however, the data drops every time i'm on a call. no 2g, 3g, or 4g indicator after about 10 seconds of initiating a call.
just trying to figure out if i have a bad phone or if others are also noticing this issue.
any feedback is much appreciated. I may switch to At&t and get the optimus g pro if this is "feature" of the HTC one

If you're on EDGE it can only do one at a time not both.

I hear ya....but it's happening from 4g to zero; 3g to zero....the data connection (regardless if it's locked onto 4g or not), just drops after a few seconds of being on the call.....
what does everyone have their data settings set to? under mobile data > network mode.....
mine was originally set to GSM/WCDMA/LTE auto....
I changed it to GSM/WCDMA AUTO since tmobile doesnt' have LTE where I live to save battery......
but the problem persists with all settings, even when I select teh LTE....
any thoguhts?

Dial *#*#4636#*#* select phone info and see if it's set to GSM/WCDMA/LTE there as well.
I had that problem. Mine was set to CDMA/EvDo/GSM/WCDMA/LTE auto from factory. I did the above and set it to GSM/WCDMA/LTE auto and it fixed it for me.

A window popped up with "automatic" or "usa band". I selected "automatic".....but i don't see anywhere to select between GSM / LTE, etc. within this phone settings hidden menu..

yes should be set to GSM/WCDMA/LTE auto or if you don't have LTE in your are just GSM/WCDMA auto.

got it....THANK YOU TO EVERYONE for their replies....changed it now...but still -105dBm to -93dBm at best......
what's funny is that my work provided tmobile blackberry sitting right next to my HTC one has awesome signal right now.....i don't get it.....although the blackberry is a 3g blackberry at best with no 4g capability.
also, i have noticed that if i switch the ONE to GSM only, the signal jumps to -71dbm.....!!! so apparently the "4g" sucks here in northern cincinnati....
4G have low coverage in all countrys, only usa have widely 4G.
If you got 4G that means you got better internet speed not stronger signal.
Signal depends on internal antena which dosent care if signal is 2g,3g,4g.

Simultaneous Voice and Data HTC One on T-Mobile
After dialing *#4636#*#* my HTC One on T-Mobile is set to WCDMA preferred as we do not have LTE coverage yet.
Voice and Data works superfluously under "4G" HSPA+ 21. I tested both while making incoming and outgoing calls.
I was told to change it to GSM/WCDMA/LTE auto when they put LTE live in my area.

Hi there erg208, I've tried all of those settings and still no success. Only for a very short time (data will stay on anywhere from 3 seconds into the call to no more than 10 mins into the call....last night was a record with 30 mins into the call) but the moment I begin to do to much surfing or send one too many emails or Gtalk for too long it's like my phone just gives up and the data disconnects and at no point during my phn call will it ever reconnect. I have to hang up my call and INSTANTLY the data turns on with all 5 bars and an H signal. AND most times I have to restart the phn before I can get simultaneous voice and data again. Do u have this issue? May I please ask if you've done an extensive test with your simultaneous voice and data? Meaning have u actually been on a long enough call and seriously surfed the web, sent & received multiple emails, chatted on Gtalk and sent an MMS all during one call and it stay connected? That would be a real test b/c mine doesn't. And if your data does disconnect do u have to hang up the call for it to come back on?? And does it work again if you make another phone call without having to restart your phone? No matter what, having to do either of those things is unacceptable b/c I have NEVER had to with any of my previous HTC devices on Tmobile's network. And I'm a flight attendant so I'm all over this country receiving 3G, 4G and LTE signals and it does it no matter where I am, if I'm moving in a car or sitting perfectly still in the same area with good coverage. Pls let me know your full experience in testing this. I really appreciate your help! Thanks

That is not true. We have decent LTE coverage here in UAE (inside the cities at least) and great 3G coverage even on highways.
I did have a similar issue that while on 4G data would drop if i receive a call but that's because 4G LTE does not support voice and my call gets "demoted" to GSM which does not support data+voice simultaneously.

Can't make calls

For some reason I can't make calls. I'm using the stock dialer on a stock rooted ROM (see sig).
I dial a number and it looks like it's working (the call timer starts counting and what not) but it never actually calls. Just silence.
I haven't been able to test receiving calls yet but I did at least get some missed calls earlier when I was away from my phone (it was when I tried to return those calls that I discovered this problem).
I'm on Verizon. I have LTE set as my "Preferred Network Type" in Cellular Settings. Data works fine in both LTE and 3G areas. Texts work fine. Just calling seems broken.
Had anyone seen or heard of this? I searched this forum but didn't find anything.
poor connectivity on WIFI network on nexus 6
I also face the problem if not able to make/receive calls when WIFI network is activated.

Are you on the 98r radio? That's the one that ships with the Verizon branded Nexus devices and is different from the radios in the other 5.1 builds.

what if you turn on your speaker?
nevermind, the ops post is from jan 14th, and someone brought up this thread again. people, this post is before the 5.1 update came out. let this thread die.

cant receive and make calls when connected to LTE

I just bought my note 5. Its the dual sim version. So the first few days was days.... i started having difficulty with making outgoing calls... texts are fine... its like 1 out 10 calls would push through. So i rebooted my phone thinking that it might resolve the issue....unfortunately it did not. Then a few friends sent me a message that theyve been trying to call me and it always says im out of coverage are... the whole time this was happening I was connected to LTE. When i changed my mobile network setting to 3g/2g .... then calls came in and went out. Has anyone have the same issue with note 5?
The international versions don't have VoLTE enabled. Not sure how to enable it. Mine also doesn't have WB-AMR (HD Voice) enabled either.
Thus, calls need to be switched through the HSPA network and can't be routed while connected to LTE. Essentially when making a call your phone switches and tries to register on HSPA, quickly.
