Mate 20 Pro and Android Auto Call Dialer Bug details

[MONRCS]

As detailed here (rebuild url by removing spaces);

It seems the bug stemmed from a missing Voicemail Option settings on the current version (126 and previous ?) of the EMUI.

Looking at my Mate 20 Pro, the Voicemail settings cant be found.

Thus from Android Auto app, an attempt to read the System Voicemail setting will cause program to throw an EXCEPTION error. Now, how do we fix this ?

Disable permissions for contacts and call log worked for me as a temporary fix.

I'm confused as if I press and Hold 1 from the dialler it connects me to my Carriers Voicemail as expected, and that's not something I manually configured.

NB haven't tested with Android Auto as I don't use it

NB I can also reconfigure by going to Call Settings| More| VoiceMail Where there are 4 options
Service Provider : Configured as "My Network Provider"
Voicemail number : configured as "901"
Notification Sound : Select
Vibrate On/Off

O2 UK provided M20P on .122 FW

Edit Add: Just installed Android Auto and starts , runs & seems to work as expected

NB also noticed you referred to the .126 FW which some peeps seem to be getting instead of .122

You are lucky Your version of the firmware provide Voicemail options. I tried looking for mine via press and Hold 1 on the Phone Dialer and viola -- No Voicemail settings i can set to . I also tried to look for it via search on the Android Settings Menu and there is none. Is it a telco activated option or is it because we have a different version of the firmware ?

Also, i did that "remove all the SIM cards" thingy to test if Android Auto will not crash when the dialer is clicked - viola -- Android Auto did not crash.

Now, how do i get Voicemail activated on my side ? hmmm

ok, here is my not so great Android Auto Dialer Bug QUICK FIX

I used TWO (2) SIM cards, 1st one is a Data Only SIM card with no Telephony service placed at slot1 of the Mate 20 Pro. 2nd one is my primary telephony sim card attached in Slot #2.

Settings:

All Data Access on Sim Card 1
Telephone Calls default on Sim Card 2

I discovered that Android Auto will always check which sim card with internet settings and will attempt to get telephony settings from there and since there is no telephony service on Simcard 1, Android Auto will skip the Voicemail setting retrieval and will proceed to display the dialer

From there, i can now initiate the call via Sim Card 2

From your other post I see you have a dual SIM version, maybe that explains the FW version difference.

Question :

Was your phone :
a) bought SIM Free Outright
b) Carrier/Telco provided with contract

If a) then I would have expected it to have all the options avaialble and be unrestricted.

if b) then it may be that your carrier/telco has deactivated some settings to make you pay extra for features.

Do you have Voicemail with your carrier ?

Bought it SIM Free.
I think the telco provider has disabled it but my previous phone which is a Huawei P10 (transitioned to Mate 20 pro a week ago) has Voicemail settings in it

UPDATE:

I recently got a PATCH update from Huawei for Mate 20 Pro FW .126 Patch 02 and VoiceMail options are there and Android Auto Dial Bug is now FIXED

Also, i dont have to remove call log and contact permissions from AA. It is now working as expected

Okay guys, this is an error due to the way the firmware is installed. It all comes down to the carriers and their software. Using the M20 pro on vodafone, AA crashes, doesn’t even start. I’m returning that phone and going with EE, and i forgot AA crashes, tried it just now and it works fine. It’s all to do with the default voicemail setting the carriers have. Also making a voicemail request by holding 1 may work for people having the crash.

Deleted VM no and re added works perfectly now

Happy user!!!

Which means previous versions of the EMUI tend to be buggy on the Voicemail settings. Either a reset of VM for those with the settings available and a f/w upgrade for those without VM options on their phone.

I just tried this and it also appears to be working when opening AA on the phone and going to dialler, just have to try in the car now and fingers crossed it will work.

*edit*
Just tried it in the car and all good also. Who needs the patch lol
