ZenFone 9 randomly restarts

Rising Star I
Hi all,
I bought an Asus ZenFone 9 from the UK online store. I started to migrate the apps from my old phone to the zf9 and once I finished I started to use my new ZenFone 9 as my main phone. However, I noticed around 3 dso that when i wentato unplug a fter charging the phone it looked as if it has been restarted. I thought it was a software update that somehow just did that so I didn't pay attention but then it repeated again and again every day since.

I started paying attention to it and started trying to disable certain features to see if that made a difference: disabled mobile data, left everything on and now I'm on airplane mode with WiFi on.

I upgraded to the latest version that was pushed some days ago hoping that it would magically solve the issue but... it didn't!

I quick Google Search revealed that sadly this issue is not that uncommon, and has already happened in the UK and Germany to other ZenFone 9 owners.

Is this a hardware problem? Is there a fix or a patch other than simply perform a factory reset and keep seeing the same issue? Can please someone from Asus look into this issue?
Plehank youase tell us some basic information before asking for help:
Model Name: ZenFone 9
Firmware Version: WW_32.2040.2040.23
Rooted or not: no
Frequency of Occurrence: every day
APP Name & APP Version (If your issue relates to the app): not related to an app
In addition to information above, please also provide as much details as you can, e.g., using scenario, what troubleshooting you've already done, screenshot, etc.


Scenario: use the phone as usual, leave the phone idle a few times a day, at some point, when you try to use the phone after it sat idle for some time you'll notice that it had restarted because you'll be asked to enter your password again and about/ status will show an up time of just a few minutes

I still have warm resets. I started to notice something. It seems related to bluetooth. 

I bought some new headphones. I had a warm reset 2 times after the headphones where turned of and lost the bluetooth connection. 

It somtimes happens when I turn on airplane mode. At that moment my smartwatch disconnects. 

Often after a warm reset calling via WiFi is noy working anymore.

When i bought zenfone 9 i had a simillar problem with random reboots (10-20 per week). First step was a guarantee service. After service and repalce my original motherbord i had random reboots 10-20 times but PER DAY. Next step was a try to return my phone (without succes). When i get my phone from service and first start phone i noticed something. Some of android apps was duplicated. After hard reset, i recover from my old phone everything without apps. Despite this some apps from my old phone was moved to my zenfone. When i noticed this, i uninstall duplicated android apps (like phone, phonebook etc.). After this i did not noticed any reboots from last 4 months so i think that problem was solved. I hope that duplicated apps caused a problem with random reboots.

I hope that this story will help some of you
