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?

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

Same issue here. Phone keeps on restarting. Sometimes several times a day. This is for one annoying and also for me a disfunctional device! I am missing some calls because the phone had restarted without my notice. This is not acceptable for a device with this price tag!

Can you check if whoever had the spontaneous reboot had activated the Smart Display function? The function that keeps the display on when you are looking at it.

ASAP please

When it restarts are you on the phone doing something or does it also happens when its idling or does it only happen when idling?

You're right, it's a problem. But if you remove the PIN from your telephone SIM in the event of a spontaneous restart, you are online again in less than a minute.
