Hi,
I have a strange problem with VoLTE...
I have a cellular problem here, I have never had before. I'm on T-Mobile in Germany and VoLTE actually is supported which is strange anyway since only T-Mobile devices sold by T-Mobile GER are supported normally. But I have one big call problem with VoLTE while it's on LTE all the time with perfect reception. No 3G/H connection when this problem happens.
If my calls aren't answered by the other person within 20 seconds calls get cancelled. Every time when someone doesn't answer on VoLTE, and everytime after exactly 20 seconds, the call is cancelled. Have you guys ever heard of something like that? On 3G/H it works normally. Calls also work normal with VOLTE, only the cancellation after 20 seconds when no one answers is a problem.

Does anyone else have this annoying problem of 5-6 dropped calls in a row when using UMTS with Cingular?
It seems that when these dropped calls occur it happens many times again in a row. Then, after 5-6 there will be one that works and will continue to work for awhile. I know that if I swicth to GSM this does not occur, but switching back and forth gets quite annoying.
I called Cingular about this and they added my IMEI number to my account which I didnt think would help and it didnt. I never have a problem with data on UMTS. I get a range of about 800kb-1333kb per second.
TIA
yup. i've had problems too. i just switched to GSM only, and no more dropped calls. UMTS on Cingular is not stable yet...so i'm waiting until it is more fully integrated.
Hi All,
I have a Galaxy Note 4 SM-N910F with BTU firmware N910FXXU1ANK4 (UK) which I flashed from the older O2 UK firmware N910FXXU1ANJ4 when I bought it.
I am having problems receiving calls and making calls when 4G LTE is enabled on the phone (I get 4G signal bar). When someone calls me my phone rings and the signal bar is 3-5 bars usually and when I slide to answer the phone it seems to answer (timer starts clocking up) and I can't hear anything (sometimes for a split second) and the other person can't hear me, then the person is directly kicked to my voice mail!
If I try to make outgoing calls with 4G enabled it sometimes works but other times it sits there saying "dialling..." then after 10 second or so gives up and stops. If I do manage to call out I get terrible phone recetion breaking up and high pitched noises sometimes. Sometimes it is ok for a while talking but eventually the call drops at some stage.
If I force my phone into 2G only or 2G/3G only then the phone seems to work completely normally.
I have had multiple SIM swaps with no luck.
Samsung walk in repair centre was useless as the empolyees all appeared to be undertrained kids.
O2 was no use saying there is no transmitter faults reported in my area.
Before I try a hard reset and flashing back to the old O2 firmware and then possibly sending my phone away for repair, is there anything else that might be going on here? Has anyone else seen this or know if it is a known problem?
Cheers,
Richard.

Most mobile providers still don't support VoLTE (don't know if that is the case in UK) so your phone needs to go down to 3g/2g when phone call is received.. So maybe there is some problem between BTU and O2 firmware (I am no expert, but may be CSC related)..
I suppose your network selection on 4g/3g/2g automatic mode, not LTE (4G only)?

I only have the option of :
LTE/WCDMA/GSM (auto connect) - Have the issues with this mode
WCDMA/GSM (auto connect) - No issues in this mode
WCDMA only - not tested
GSM only - No issues in this mode.
In phone dialer hit settings. There should be a volte toggle if there is turn it off.
I don't have any issue like that. 4G turns to 3G or 2G when receiving/taking a call. May be u hav an issue with ur firmware
I've tried flashing back from the BTU UK firmware back to the original O2 UK firmware and the problem remains. I also tried a hard reset afterwards leaving the same issue.
I have noticed that the issue does occur with 3G as well as 4G but it seems to be a bit more stable. 2G seems the most stable.
I have arranged with Samsung to send my Note 4 for repair so hopefully that will resolve the issues.
I have the same problem using 4G. Sent for replacement. Waiting for feedback..
got information that warranty service did find the problem and in a week or so I will get new one
I HAVE THE SAME PROBLEM!!!! THANKS A LOT !!!!! I WAS LIKE CRAZY TRYING WHAT CAN BE WRONG WITH THIS....
In my situation i can
send and receive sms on all mods
I can call in 4g but i can't receive calls when im on 4g... - just only hire is a issue
Last time my charger when i was charging in night get burn and i think meybe form that time... i have phone 3 weeks brand new.
From the beginning, I experience this issue and it is really a dealbreaker. A phone's main and most important feature is to make and receive calls... I constantly miss a ton of calls almost every 3/5 calls are missed. To the people who call me it says that I am outside network coverage or the call cannot be completed at the moment. At the same time I look at the coverage on the phone and it displays FULL coverage + 4G mobile data running without interruptions. When I try to call or return the missed call I don't have any problems at all. I live in Eastern Europe, the bands seem OK, they are according to the EU standards. Does anyone else have the same problem or does anyone know how to fix it? The OTA updates don't help for now, nor changing the SIM slot.
So i bought a second hand galaxy alpha phone. It was perfect in shape, no scratches or anything, meaning the phone was ell maintained.
The problem comes when im over LTE(4g) network. I try placing a call, it waits like 45 seconds and then it drops. i try calling for the second time and then after a couple seconds the signal drops to EDGE and start calling. after the call it stays a EDGE forever, unless I dial *#*#4636#*#* --->phone information--> set preferred network type: "LTE Only",....once signal shows LTE i can get it back to "LTE/CDMA/UMTS auto (PRL)" mode and keep surfing internet with 4g speeds.
Another related issue, if someone tries to call me when im over LTE, the phone doesn show any incoming call, but to the person calling, the call rings normally. So i dont get calls :S
I though it was a software related issue, so i rooted it and upgraded to andorid 7.1.2 lineage. but still the problem is the same. what shoud i do, i searched the internet and the answer is nowhere to be found nobody has this problem either
Hello,
i'm using redmi note 4 snapdragon 3/32 version for almost 1 year 6 months.
Suddenly i am facing network issue.
Though the network bar shows full network but still not receiving any call neither i can call others.
If i change network to gsm only it seems works for a while
but i want a permanent solution.
*i reset phone. Even tried different rom*
if this is a hardware issue. Is this critical?
Thank you.
Maybe it's related to your operator
Some operators switch from 4g to 3g or 2g when you receive a call or try to call someone
maybe your operator has a problem with this switch and so you are not able to call and receive
