Missing about 5-10% of my calls...goes directly to voicemail...since NOUGAT - Galaxy S6 Q&A, Help & Troubleshooting

I am pretty frustrated with my S6 (sm-g920w8) after taking the update to Nougat. I do not know why I upgraded.
I never missed a call when I was on Marshmallow but since the upgrade in July, I have missed about 5-10% of my calls daily that go directly to voicemail and are not registered in my call logs. I tried everything from factory resets...to a new SIM card...
I am at the newest firmware (G920W8VLS5DQG1). I am NOT rooted. My phone status shows a valid IMEI (although it does show my phone number as unknown).
Please anyone with suggestions I would love to hear...otherwise I may have no choice but go purchase a new phone as I rely on my phone for business...right now I downgraded to my s4 until I do something about the problem.

[Q] No phone Calls, only data and text

I got this phone a month ago and flashed various stock based ROMs with no trouble. I then tried AOSP (cm10.1, eclipse) and everything seemed to be ok although, I couldn't make phone calls because I have no service where my house is and was never able to test (I remember that in settings->about phone->system status it said it wasn't activated and it didn't display my phone number, but when I went back to stock it did display my number). Then I went back to a stock ROM and my phone would not make or receive calls. It would send and receive text and was able to received data via 4g but when trying to make a call, it would say "dialing" and then eventually just stop without making any type of connection. when calling the phone it would go straight to voice mail as if it was off. I used odin to go entirely stock and had the same problem. I ended up returning the phone and getting a new one and I am running Clean rom 5.5.1 and everything is working fine but I'd really like to try other roms but I don't want to have the same problem again. anyone know if it was just a bad phone or if I did something wrong? if so, what? any ideas would be greatly appreciated! Thanks!
You should have consulted xda before returning the phone. With your original phone, you needed to reprovision your sim to properly have your data return since you had Odin flashed. That code only works on ICS though.
The loss of data on your prior phone was from flashing CM10.1, you just needed to follow this post to resolve your issue without Odin flashing a stock rom.
Edit: The sim reprovision code suggestion is still valid BUT disregard the data loss part...

[Q] trouble ending calls

I just got this Moto g through Amazon and got it set up with Immix service in the US. It worked for the test call in the store but randomly now when i place a call, it ALWAYS starts a conference call. (has a manage conference calls button above the hang up button, etc) even though I only clicked on one number in my contacts. When I try and press the button to hang up the call, it flashes for a second (almost looks like it goes back to a single call) and then comes back with the same conference call view. I can't get it to disconnect the call on my end no matter what I do. Even clicking hang up in the notification will clear the notification but it comes right back up again. It just gets stuck in the call. If another person calls me, I am able to hang up the call no problem. It's only if I dial out. I've tried a factory data reset, I've reflashed the factory image files, reinserted the SIM, tried a new SIM, put this SIM back in an old phone, etc.
Anyone have any ideas what could be causing this?
all these views and no thoughts?
I ended up contacting motorola and they had me ship the phone back under warantee but so far, it seems they have only lost the phone in their processing/repair facility. I'm not super convinced that when I do finally get it back that it will be any better off....
i also got this same problem with my phone buyed from kodoo ... I got this only with 4.4 version of the system. I got this on Stock ota 4.4.2 and also on Us retail
this is very annoying since it will drain battery, it need a reboot to end the call .... really disappointed about this issue
but no chance for me, I've void my waranty by unlocking de bootloader
Update on the issue: if. I call the service number of my carrier (611) it won't trigger the conference call and I'll be able to end the call without any issue

Interesting. Got a replacement from Motorola under warantee after they lost the original one in their processing facility. The new one came and its working OK so far on 4.3 but it asks regularly to update to 4.4 right out of the box. I thought that might have been the issue to begin with so I haven't done the update yet. From what I've read, there isn't any way to go back to the 4.3 after the OTA to 4.4 on the phone either.
i'm not totaly sure that it safe to downgrade but i've done it more than one time ...
i'm also ot sure you can do it with locked bootloader ....
but i've done it with flashing one of those image : http://sbf.droid-developers.org/phone.php?device=14
anyway i'll keep 4.4 either if i found an fix or not ... a simple reboot after a call isnt so hard to do

SIM hacked/infected - reflashing does not remove it

Hello XDA.
Over the last three months, my phone has been regularly sending SMS's to a number in Singapore. Of course this is not something I have had anything to do with.
I have an LG G3 (D855) phone running Android 6.0_EU. My phone has been rebooting itself numerous times a day with the message that the SIM card was removed. It starts back up and usually works without a hitch. Checking my carriers log, I see that every reboot correlates to a sent text to Singapore at the exact time the phone was booting up again.
There is absolutely no evidence as far as I can tell that these messages are sent from my phone.
As I only just recently discovered this, I started investigating. I flashed my phone with a 6.0 KDZ from a thread on this forum, but it still rebooted afterwards and sends texts. I placed my SIM into my wifes D855, and it started experiencing the same issue. When we placed her SIM back into her phone, we could see that her phone number had ALSO started sending texts to Singapore.
We flashed her phone, put in a completely fresh SIM with an unused phone number, and that number started sending texts as well.
This leads me to thinking that there was a virus or malware on my own SIM and phone which then was tranferred to my wifes phone via my SIM and then from her phone onto the fresh SIM.
My question is this:
Has anyone ever heard of a malware/virus capable of replicating itself in such a degree that it exists on SIM cards and on the phone while it survives reflashing a stock ROM?
Also, is there any way to competely, and i mean completely wipe a phone so a bootkit is removed as well?
I hope there are some wise heads out there who has any idea regarding this.
According to Google there aren't really an precidences of what we are experiencing.
Infection has now been removed
Persistent memory can be a nuisance.
Confirmed infection has been removed by two days of inactivity on a fresh SIM-card by doing the following:
Rooted the phone using KingRoot and a guide here on XDA
Installed the custom Recovery TWRP
Installed the Lineage OS 7.1.1 custom Firmware
Through this, we can with a 95% certainty determine that the virus/malware resided in the recovery partition and the reflash of stock ROM did not flash the recovery partition.
In fear of being reinfected, I have not inserted an infected SIM into the new environment test test, whether or not it would be reinfected.
I hope this helps anyone who may experience this gnarly situation.

No cellular service?

I've got a used Mate 9 that I've been trying to get cellular service on.
When I insert a SIM card, if the card was in a device that was working, it will briefly look like it's going to get service, showing the carrier name and signal bars, then shortly thereafter go to "No service" or "Emergency calls only". It does recognize the card and pull my number from it and such.
According to Huawei when I look up warranty information it is the US Mate 9. It's currently running MHA-L29C567B130. (It was running Oreo but in an attempt to eliminate that as a reason for it not working I downgraded it with Hisuite to the last Nougat release.)
It doesn't seem that have been rebranded or anything of the sort but I can't be absolutely sure about that.
I've tried going through these forums and didn't come up with much (or if it was there, it's buried in dozens of pages of posts).
Is there anything I can do to get service on it?

HELP: "Not on Registered Network" while trying to place calls after recent update

HELP: "Not on Registered Network" while trying to place calls after recent update
Hi all, yeah I'm getting this error now after recent update, any help greatly appreciated.
Factory ROM
Unlocked S7, formerly ATT&T
Edit:
I should mention that I've already done steps 1-7 here:
(can't post links yet)
Turn off and remove and re-insert sim card.
Attempt to manually connect to all scanned networks, one by one
Reset Network Settings
Start phone in Safe Mode
Nothing works, and I can't contact my carrier, SafetyNet Wireless, because I have no means of placing a call (I used to be able to use Google Hangouts if I found myself in a situation like this)
I'm really upset about this and have turned off auto-downloading of Software Updates.
How an update could break my phone's primary functionality is completely beyond me. God damn there's some real idiots working for Samsung at the moment.
