ZenFone 9 randomly restarts

HelpingHand
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 don't agree very much for 2 reasons, firstly because in the 2 Asus Telegram groups of which I am the administrator no spontaneous reboot report has yet been received, secondly because my device comes directly from Taiwan (it has all the writing in Chinese) and it is a 16GB and 256GB supplied to me in test by Asus Smartphone Italia. So I'm Italian, but the Zenfone 9 in my possession, in my opinion, is not among those intended for the European market

Mine also has Chinese writing on the packaging, and I bought it in a store from the official list.

Bought mine from the ASUS US site and having the same issue. Thus far, only while idle, happening 1-2 times a day, though not everyday that I've noticed. Just updated to the latest software, hoping that helps.

I have a suspicion that is becoming more and more important. I am seeing that there are more and more users reporting this bug but there is a common fact that many of them tend to have. They are from Italy. This is a fact that suggests that it is due to a specific problem in a batch.

It's been 3 days since I turned off the Smart Screen and I haven't had any more spontaneous reboots. I'm still with 2050.29 now I got the new update to 34. Do you recommend me to update? In my opinion the reboots that happen when using it are related to the Smart Screen.

I have always had the smart screen disabled and I have reboots. And I also have the box in Chinese and it is bought in Italy. But my reboots are every 4 or 5 days. Once I have gone 2 weeks without reboots.
