Xperia XZ mobile network issues after Android Oreo upgrade

[Darkbearx]

Hey there, 

About 1 week after the Android Oreo upgrade, my phone suddenly lost mobile network signals at home. However, when I am outside my home, the signals came back. What gives? Anyone experiencing similar issues?

Seems you installed a Faraday cage:smileysmileywink:

Now serious:

- reset apn (access point names) settings

- Try to reboot into safe mode and see if behaviour is the same.

   If it is better then probably an app is causing problems.

Hi Strampke,

Unfortunately that does not work.

Same with me after update Oreo. Loss Mobile network in room and work when outside.

Yes I am experiencing what above user is but a bit more finite, on SIM #2  there is an ATT phone account built in and it comes up NO SERVICE, things I have checked are as follows:

1. APN SETTINGS ARE CORRECT

2. CELL DATA SELECTION SAYS SIM #2

3. CALLS SELECTION SAYS SIM 1

4. SMS MESSAGING SELECTION SAYS SIM 2

THERE IS AN ACTIVE ACCOUNT WITH TELEPHONE NUMBER ASSIGNED ON SIM 1 & SIM 2

SIM 1  424-433-0628

SIM 1  818 519-0739

What gives here

thanks for any help you all can offer
