    My work purchased 4 new Zenbook UX392F models 2 months ago and all of them have this issue. We've tried various things to solve the issue but nothing has worked. Please let me know what the next step is. Thank you.

  • Hi there! I am also having the same issue. I have a zenbook UX431F.

    I'm having the same problems as mentioned above with a Vivobook S14 S430FN-EB209T that I've JUST BOUGHT TODAY for more than a thousand dollars. Once I unplug the AC the video returns to normal, but it is horrible while charging. As I'm using my laptop all day long is is quite frustrating to be honest. It showed in MS Teams, Messenger video call, Discord video call, Google meets in browser, etc. My windows is up to date, and I updated the bios also (308).

    Any ideas when will be a solution to this problem?

    Hey guys,

    I'm having the same problem as mentioned above with a Vivobook X512fj-ej228t. I don't have the problem with the camera app (plugged or not to the AC). But I do have the problem when it's plugged to the AC with google meet and cambly (and probably other software). Once I unplug the AC the video returns to normal.

    Hope you guys can find a solution ASAP.

    Similar issue with the Zephyrus GX701GX - appalling webcam flicker that renders it unusable but only when connected to AC power supply. I've just updated the BIOS to the latest available (GX701-AS.309) but to no avail.

  • I’m returning my ZenBook Pro Duo UX581GV, It is completely unacceptable for a ‘pro’ computer to not have a working webcam! Especially as my business is so reliant on virtual meetings at the moment. £3000 for a machine you can’t use for meetings... It’s embarrassing

  • Dear all above users,

    all PM have been send.

    Please kindly check. Thank you so much.

  • @Blake_ASUS Hi,

    I haven't received a PM from you. Could you please resend one? I'm having the problem on a Vivobook S14 S430FN-EB209T.

  • Hello matekoves,

    Sorry, I just send it!

    Please check. Thank you.

    I have the same issue with my brand new Asus ZenBook Pro Duo.

    Is the fix ready yet? How can I get it?

    That new BIOS fixed the problem! Thank you so much!

  • Hello.

    I have a brand new ASUS Vivobook (Asus VivoBook S 15.6" FHD Core i5-8265U Laptop - Moss Green SKU: S531FL-EJ545R). The in built webcam flickers with grey lines then a green screen every 30 seconds when I'm doing a video call through Zoom. As people here have suggested, it stops when I unplug the power charging cord.
