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

Hi everyone
I'm using Singtel ROM version 1.31.871.14 with Radio version 1.58.16.27, and I have complaints from people who said they called me but I never see a missed call on my Touch Dual device.
Did anyone suffer same problem?
Do I need to update the ROM or Radio version ? if yes, which version should I use ?
try this changing your network type to GSM
settings > phone > band
when your device is online with gprs you will not receive calls.
changing to gsm will make it worse...
I have a same problem.
Here in my house where I should have full reception, I have only 2 lines and it falls to 0 from time to time.
Does anyone know anything about it? Is it radio rom problem or?
I also would like to know which radio rom gives the best reception - if not the default one delivered onto your phone.
My info - T-Mobile branded HTC Touch Dual (named Touch Plus by T-Mobile).
Operator - T-Mobile
Country - Netherlands.
Very poor reception, also when only GSM Band selected. Phone is now in for repair by T-Mobile - i think it has an antenna problem but could not get my finger at it.
Anyone any info to lighten things up ?
Would be highly appr.

I don't believe that the above is correct. As far as I am aware, calls are independent from data. I have GPRS connected all of the time, and can still send and receive calls.
Data and calling use and not independant - when you make a call notice that your GPRS/HSDPA connection drops and then restarts when you end the call. Texts are not affected as you can send/receive texts in mid-call as well as during a data connection.
hey all
i've got a problem with my droid pro in eu on gsm/umts network.
when i'm roaming and use gsm only (no umts) my mic and speaker are dead. i can make a call and receive it, but i cant hear anything and caller doesnt hear me. display shows seconds have past so line is opened. i can even receive sms and mms just fine and send them, only cals dont work.
if i change from gsm to umts only, then calls work fine. when im on home network everything is ok.
funny thing is, that if i make a call on roaming in umts only and then change to gsm only i can receive first call, then it's all blank again.
i have stock rom
tnx
teva
probably the problem was with the network where you was located. did you tried another network?
my droid pro works nice in roaming, in both gsm and umts.
I am facing a similar issue.
2G 900/1800 Mhz -- Voice & Data Work fine.
3G 1900 Mhz --- No Voice, Phone re-boots. Data works.
So I have to use the phone in GSM only mode.
I am on 2.3.3 / Verizon 4.6.4 update.
My new operator have same issue! (no with the old operator!!)
In a specific location i can't make/receive a call in only 2g (i can send/receive sms and data traffic is ok)... But if I switch in 3g i can do everything...
For my operator it is an issue between sim (by ORGA) and droid pro and so I'll replace my sim...
I didn't find non ORGA sim, but i have bought a dualsim adaptor, for seeing... Nothing...!
On my operator (TIM), when i'm on edge in only same locations, i can't make/recivie calls... Not with my ex operator (wind)..
But... you can try to compose on your dialer ##7764726 then call, then password 000000
verify
06 test mode
next
next
service option switch to 13k, or others, then back...
Make a call, or try this configuration
if you restart your phone you must reselect this...
Tomorrow i'll try...
I have new S5. NO CALLS come in if are on LTE/CDMA network browsing internet and someone is trying to call you in the same time. Sprint had me changed to CDMA and in that case calls do come through. Anyone else has this problem?

As i understand, the problem is if 4G network doesn't support voice over LTE (4G is only for data). And when you receive call, the phone that is on 4G network, it must switch to 3G. And at this switch error happens. that's why you don't get call, that's why i get SMS with notification of missed call.
Been testing between network modes "LTE/WCDMA/GSM" and "WCDMA/GSM".
When i am on "WCDMA/GSM", i have no problem..
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.
I have recently bought the MI A1. While buying itself it was updated to the latest may patch.
The problem is while on 4g network, I cannot receive nor make any phone calls. For calling I have to manually switch to 3g/2g mode from *#*#4636#*#* menu. Is this a normal behavior of this phone as my other phone swiches to 3g while incoming/ outgoing calls and back switches to 4g after the call is finished.
PS: my network doesn't support volte. Phone is manufactured on Feb 2018, it's not modified by any means.
That's not normal behavior.
I've never seen a phone where You have to switch between 3G/4G/LTE for calls and data.
Can You try a SIM-card from another service provider to see if it behaves differently?
If You check at https://willmyphonework.net/ are all bands supported with Your provider?
Or, in worst case of course, try a factory reset and see if that makes any difference...
Set to 3g/4g in *#*#4636#*#* menu.
Airtel doesn't support volte in all circles yet. Only rolled in few circles. In 3g/4g mode, it'll be mostly in 4g mode if nw strength is good & switch to 3g when you call or receive a call
