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

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...
In device info I find several options for the network mode: lte/gsm, lte/cdma, or lte only, but I want something like lte preferred. If I switch it on lte only, phone calls or sms stops working (can't receive or send). Is there anything I can try to prefer lte all the time? My Vodafone carrier in Romania doesn't support VoLTE and whenever I make a phone call it goes to 2g, then it takes a few seconds to switch to "H", but it almost never goes directly to 4g. I'm also rooted so some exposed module or something similar would also be appreciated.
Basically what I'm looking for is to prioritize lte all the time, but switch to 2g/3g when I make a phone call or there is no 4g signal. Can anyone help me out pls?
My network doesn't currently support voice over LTE (VoLTE) so everytime I receive a call my signal switches back to 3G (H) or 2G (E). I noticed that after a call, it takes time for my S8 Plus to switch back to LTE. Is there an engineering or advanced configuration settings that can be set so that after a voice call the signal goes back to LTE immediately?
This maybe not an impossible thing because I noticed on some other mobile phone brands that the switching back to LTE signal after a voice call is kinda fast (within 2 to 3 seconds) after a voice call.
Thanks
I had a Sony Xperia Z3c on T-mobile. It was an unlocked phone. When I made a call it would switch to 3g because the phone does not support voice over LTE. Most of the time it would take a while to switch to LTE again unless i went into airplane mode or turned data off for at least 10 seconds OR what seemed like if I was driving maybe it would connect to another tower.
So maybe it's normal with phones that don't have VoLTE?

Hi! I am experiencing faster switching on other brands like Huawei and LG. They switch from 3G or 2G to LTE between 2 to 3 seconds after calls.
And yes, that is correct. I usually switch my phone's airplane mode on and off to get the LTE signal back faster.

Hi! However I used a different brand phone and it's switching fast back to LTE immediately after call ended.
Thanks

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

I need help after the OTA January update I almost can't receive any calls, it says my phone is turned off or out of cell reception. The same is when I try to call I just can't get signal and the call is ended. Before those update when I call I can see it switching to 3g and my cell reception is always full now when switch to 3g reception is going down to nothing.
I am 4g preferred mode like before in Oreo I live in Bulgaria and using A1 network.
Basically I have to change preferred network to 2g if I want to call or receive call because if use 4g preferred the phone start to change very slow between 4g 3g and H
