Accepting calls when in 4G mode

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.

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.

missing/disappearing calls with tmobile s6

Hi does anyone else have disappearing calls when connected to LTE using a tmobile based s6?
This issue only occurs when LTE is active.
An incoming call will ring once or twice and go straight to voice-mail even though I have full bars

Go to your Phone App settings and turn off Wifi calling and VoLTE.

I'm sorry I have already disabled WiFi calling, and the problem persists but also - I don't have a separate 'VolTE' setting to toggle. Is it because it only appears if I have a T-mobile sim card inserted?
Thanks for your help!
EDIT for anyone who may run in to this issue: I fixed this by flashing Emporia Rom by iB4STiD, it seems to disable whatever t-mobile left over sorcery that was messing with AT&T calling because the rom is not based on t-mobile firmware
Now the calls come through 99% of the time but sometimes takes about 5 rings to connect to me. . arrr

happens to me on even international firmware too. only works well right when i reboot the phone.

I have this issue also with a tmobile s6 on att. What method did you use to unlock the phone? I used the metro pcs firmware to unlock the phone and when I updated to 5.1.1 is when all the issues started. On 5.0.2 I used the tmobile unlock app and everything worked perfect. I receive one in every 3 incoming calls, like you said it rings twice and mine doesn't even go my voicemail, it just says "the wireless number you are trying to contact is unavailable then hangs up", out going calls take 30 seconds to a minute to connect, very annoying. Talked with att on the phone for hours about this problem and they cant seem to get it fixed on their end.

Same...I disabled lte and just use 4g, seems to work fine.

4G connectivity while on call

I was using single SIM so far, while receiving a call, 4G would change to 3G but will still stay connected, so Truecaller would work.
Currently, I'm using a second SIM for 4G connectivity, and SIM 1 only far calls, but the moment I receive a call, SIM 2 looses data connectivity and Truecaller can't fetch any details about the number.
Anyone knows any workaround for that ?

I am facing the same issue , anyone please provide a fix , my truecaller also not showing details of calls.

My phone sometimes doesn't receive calls or texts.

My phone periodically doesn't receive calls or texts. I've tried resetting it. The calls don't show up in my missed calls but the voicemails do show up. I'm using the international version of the Note 8. Anyone know a fix?

Does the data drop out too when this happens? Try taking your sim card in and out again. Might be a problem there.
Have you got any do not disturb settings on?

Nope the data stays on. Outgoing calls work fine as well. All the do not disturb stuff seems to be off.

Are you rooted or did you install any custom roms, etc.?

I have had this issue with several phones, the culprit has been always the type of connection, sometimes even if full bars showing, I have to switch to 2g or 3g, 4g and 3g having the issue, 2g working always fine, dont know why, but I have learned to live this way, this happening since my S3, so, In my case is carrier signal fault

What networks are you both on? If it is the same, that may be your answer...
I would check with the network to see if the masts are under maintenance.

I wrote a post here in March 2018, but, some time later the issue diasppeared, from june, all is fine, in the end, I think it was the carrier that was working on the transition to 4.5G to implement their VoLte calls service

I have this same issue and with the same phone as well

I have the same issue, and i think it as to be with the position of the phone... when its down missed more than when its on vertical... could be just coicidence but its the only thing that i note
