When i deactivate the VoLte button every single call its perfect . Any opinion on this it would be helpfull. Is this something to do with the operator or the firmware ?

HUAWEI ASCEND MATE 7 Version MT7-J1

Good morning I want to make an inquiry and see if someone can help me, buy this fabulous smarphone Huawei Ascend Mate 7 model MT7-J1, I live in Cordoba Argentina Huawei it works perfect but I have a problem ...... When you use mode Automatic preferred network (4G / 3G / 2G) leaves me not receive calls, or if I call (DISCAN) continuously given as busy, as if I were on a call, I myself make a call from another phone to my number in Huawei and not receiving my call ...... da busy line, also when I want to make a call from my first attempt Huawei terminates the call, the second attempt disappears from the notification bar 4G and only then performs the call went to my provider of Movistar service to see if my problem was SimCard, tried to take it off the other smarphone and works perfect, or is it a problem in my smarphone, I call us the attention that selecting the option .. ...... Automatic Preferred network mode (3G / 2G) ..... the problem goes away ,,,, in this way can receive and make calls perfectly, the fact is you buy this model MT7-J1 because it is the only model in this line that supports the band 4 (B4) used in Argentina to use the 4G / LTE and although all of 4G works more perfect in this smarphone I only have this problem with the calls,
If anyone can help me and know how to solve this problem really appreciate it, send mail to HUAWEI but never answered me, that's what I do not understand, because HUAWEI offers its website, if when customers have a problem never respond or offer help and here in Argentina HUAWEI service ...... not a rock, I hope you can help me thank you very much from now ........

did u managed to fix the problem? i am having a similar problem myself and looking for a solution that doesnt require me to reset my phone.
I`m having the same problem with Honor 8x Max, the mic is ok, Calling with Skype or Whatsapp working fine. The problem with distorted voice from my side is only on mobile network calls on 3g networks.

Jio sim "mobile network not available" please help me with this

Hello guys,
I am facing a real big issue after updating to the stable android pie release on my poco f1
I am using a jio sim. The incoming calls are not shown on the phone. Whenever a call comes to my number it never shows on the phone the caller will hear the dialer tone as normal
Also when I try to make a call it shows a message mobile network unavailable, mobile data and sms works fine all this time.
When I reboot the phone none of the issues are there for 15 to 20 minutes then it comes back.
There were no issues when i put the sim in the second sim slot but I need to have the same card.
I am really frustrated about this issue, I have missed many important calls as it never showed up on the phone
I cannot find any one else facing this issue. What could be the reason for this ? I hope it's some kind of software bug that can be fixed.
Please help me to fix this guys
Thank you

Mate 10 Pro - Call end problem after upgrade to EMUI 9

Hello
I have tried to search for this topic but couldn't find anything. After upgrading to EMUI 9 on my MATE 10 Pro, any call I make, call ends then connects again and sometimes when I receive a call and I answer there is another call with the same number (like call waiting). I have hard reset the phone and didn't restore anything and still same problem. I have 2 working SIM's and everything was working fine before upgrade.
Any one else having this ?
