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

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

Yeah up time is consistent and battery usage of the phone not restarting. I'll try what the other poster suggested by turning face recognition off

I had similar issue. The faceunlock is responsible for it.

Try to turn it off. Should help.

Had my first random reboot while using JuiceSSH.
Screen input froze and after about 20-30 seconds the phone rebooted.
This was the first time in 1 month of usage.

In the latest Android 12 version.

Glad I found this thread, so I dont need to think I'm crazy about the phones behavior. Love the phone just not the reboots...
That said I have the same problems with nightly reboots, and sometimes during the day.
Just got the phone back from service with the note that no problem was found during stress test and that they had updated the firmware. I'm not impressed with that troubleshooting to say the least (specialy after finding out that is seems to be a not to uncommon issue).
It did reboot as usual the first night, then I removed the simcards to see if it had something to do with them and it has been on for 36 hours now and that is some kind of a record. Just inserted the simcards and enabled the logging after reading this thread.
No facial unlockenabled and I do not charge the phone at night either.

Hi @andreas_r , I'm the original poster and you seem to have the same issue I had. I'd advise to follow the solution I posted a few posts back. After having the motherboard/mainboard replaced I haven't experienced any restarts. Good luck
