ZenFone 9 randomly restarts

HelpingHand

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

It is already restarted. Never have it seen restarting when waking it up.

@Mattias_ASUS pretty sure you should note this down as its going to nail the potential culprit down considerably.

So, would it be right to assume that the firmware released earlier today is not to solve the random restart issue? any details as to what is included with that firmware? (the release note is quite brief)

The release note just says:
【Release Note】
Optimized system performance
Optimized Hands-Free voice call performance

I turned off the Smart Screen this morning and have had no spontaneous reboots in the last 23 hours. I haven't updated with today's firmware yet, I still have version 2050.29

I think the smart screen being on or off is unrelated to the issue. It will restart again regardless. I suggested a few posts back to remove the SIM card or try "airplane mode". It does work for some people.
I also mentioned a solution a few posts back, difficult to accept but so far effective. @Airedale have you provided logs to the admin?
