As the title says, I'm having issues making calls when my phone is on LTE, when it's not it works just fine and I can make calls but as soon as it goes over to LTE again I loose the ability. My data works fine and so do txt messages just no voice calls. When I try to make a phone call the phone just sits there at Dialing.
I'm running Sphinx ROM atm however this wold happen when I was on CM11 also.
Any ideas guys?
With Miroslav's rom I perform calls without trouble. But there is one glitch...After finishing a phone call, I might lose signal completely and the phone will reconnect to the network. This usually takes about 20 seconds before the phone is connected to the network and ready.

Hello,
I have my phone for few weeks already and today i noticed one major issue. I will try to explain everything as clear as it is possible.
While i am on 3g network, there are no problems at all. I can make a call, i can receive a call, i can receive SMS etc... Everything works as it should be.
When i switch to 2g that's when the problem comes in. In the first 15 seconds after switching to 2g, i can operate my phone as in 3g - i can send and receive calls, i can send and receive SMS'es. After 15 seconds there is no ability to receive any call. The caller alway hears the same song: "the phone you are trying to reach is either turned off or out of radio coverage...". Also no SMS'es can reach my phone. Despite of this, i can send a call any time i want...
There's one thing i've noticed. When i turn my mobile data on - everything works just fine (you should be familiar with turning off mobile data function), but this is unacceptable to my mind. It seems that when i want to receive a call, i should be on 3g (doesn't matter if mobile data is turned off or on), or on 2g but with mobile data turned on...
I did one test - changed the APN's entry to a messy one, and left the mobile data on. Still wasn't able to receive any calls. Thats leads to a statement: while on to 2g, i have to be connected to the internet to receive a call, while on 3g, i can disconnect form the internet and still be able to receive all calls.
Additional info: HTC Desire - unbranded, non-rooted, stock ROM.
Can anyone help me to solve this issue?
It seems this problem only appears at home. At work (15 miles away form home) i can be on 2G and still able to receive incoming calls... Any ideas?
After rooting my H815 (Vodafone UK) throughout most of the day I can't receive or make phone calls, the signal also at times during the day will completely go and I have to restart to get the signal back (which sometimes works) However I can text and use the Internet.
The main problem I've noticed is when I call someone it automatically goes to 3G and works but if it remains on 4G it will say dialing then completely loose signal then when I hang up the signal comes back.
Anyone know a solution to this?
I am having issues with the P8000 phones I have. The phone is taking too long to switch from 4G to 3G when receiving a call so it goes to voicemail everytime. If it is set to 3G only it rings perfectly.
Dialling out also takes an age as because of the long time it takes to switch, but due to there not being a time limit, it does finally dial after about 15-20 seconds.
Has anybody had this happen to theirs and was there a workaround at all? (They are using Telstra in Australia)
Also when you factory reset the phone it clears the IMEI info and you have to enter engineering mode to put them back, is this normal behaviour as I would expect a factory reset to leave the IMEI information untouched.
Hopefully someone can assist me with a workaround.
same thing here...

I'm having similar issue... the only difference is that I do not have 3g since I leave in canada and frequencies don't match.
Anyways, when I set my phone to 2g, I can call and receive calls no issues.
Once I select 4G, I'm able to make calls (after a while since the phones takes it's time to change from 4g to 2g) but I cannot receive... I'm assuming the phone does not know a call is coming since calls use 2d...
Hopefully this can be fixes soon.

update
after a conversation I had with my provider I may have identified the issue...
LTE does not carry over call service (only some provider through voLTE). So, when a receiving call is arriving, the provider sends a signal to the phone (called non assess stratum) that triggers it to change to 3g or 2g to receive the call.
when we want to make the call, the issue does not applies since the phone already knows we are making a call and automatically changes to 2g/3g.
so, will someone be able to help us on how to make sure the phone get the signal from the outside to change network type when an incoming call is arriving?
hope so.
thanks,
For the invalid imei after factory reset (or firmware upgrade), it doesn't happens everytime but it happens often. It's seems to be a problem with all mediatek based phones (it's the case on all my previous mediatek phones(5))
Cheers
I am experiencing the same issue re: no calls coming through when in 4G cause it doesn't switch to 3G in time and it goes to voice mail. (I'm with Telstra - Australia)
Has there been any update on this issue?
My device: T mobile s4 SGH-M919 using stock rom Android 4.4.4 with all OTA updates. Phone was moved to MetoPCS a year ago.
There is no coverage at my home so I rely on wifi calling to make and receive calls. For the last year it has worked just fine but in the last week I began having a very frustrating problem:
If I MAKE a call over the wifi, no problem I can hear them and they can hear me.
If I RECEIVE a call over wifi, I can hear them but they CANNOT hear me.
When I am not on wifi calling (ie using cell), everything works perfectly both making and receiving calls.
I researched the problem and this is what I have tried so far:
1. connecting to different wifi connections in entirely different locations - same problem
2. using bluetooth headphones or speaker instead of the mike - same problem
3. disabling Google Now Voice on every screen - same problem
4. factory reset - same problem
5. made sure I do not have any phone recorder apps installed (I do not)
6. switching the mute button on and off during a call - no change
Can someone please give me some advice or direct me to an answer. Needless to say Metropcs tech support is unable to solve the problem. For me this issue is not trival as I require wifi calling at home as I am in a rural area with no service.
Thank you
This happens to me as well. However, if i am to say "answer", and allow the voice command to answer the call it works properly but starts the call in speaker mode. Then you just turn off speaker, and conduct the call normally.
This has happened to me with most of the roms i have tried.
Haven't you tried on regular call? You listed no coverage in your area.. but, it should be some where 10-20miles away your area..

Yes, If I drive to a covered area and am not on wireless the calls work perfectly in both directions.
Do you figure out yet? I get a sch-m919 has reversal problem of yours. It make wifi call fine. When make regular phone call, they can't hear me and I get hear them. I guess, we have to try out the custom rom.
Currently I am in stock room.
My phone suddenly drops the network (Wi-Fi and cell network) but it is not in airplane mode.
I won't be able to receive any calls, but the caller will hear busy tone.
During the whole time my network shows few bars, but it is probably fake network.
I am just missing many calls due to this problem, and when some one notifies over other phone I will get to know and I will put into airplane more and back, the network resets and works fine.
Can anyone know what is the problem ??
I have reset my phone also, but of no use.
Thanks in advance.
