Camera Hacked

Hi Everyone!


Yesterday, my phone was just charging while idling, locked, and screen turned off. Suddenly, my camera turned on - I knew it turned on because it suddenly flipped and faced the front for a second, and then turned off, and flipped backwards into the default position again. I was stunned because it never happened with the locked idling phone before, and I knew something's wrong.

I am writing you to ask you, if there is a log, or any way to find out which processes have access the camera in the last hours.

I don't have any custom apps, only standard stuff from PlayStore. I didn't install anything new for the last few weeks, or a month, except Twitter. I installed Twitter that day earlier, and that was the only new app I had since forever.


Please help me out!


Thank you!

    Hello,


    Can you share the list of authorized apps that access to the camera ?

    Settings >Apps>App permission manager>Camera> 3 dots to show the processus system

    A screenshot would be nice ... This will show which services have access to your app.

    Here is the screen. It's there any way to see the camera Access log somewhere? What do you think? See anything unusual?

    A long screenshot could have been better 😅, maybe you received a video call which was quickly denied.

    The only advice I can give you is to denied all the camera permission and see if it's happening again !

    I realized about the long screenshot a minute after posting, and then I tried editing, and inserting a new long screenshot instead, but I literally cannot remove pictures while editing here, no matter how I try, so there's that.

    I checked my call logs and I didn't have any calls. Also, apps don't enable camera automatically upon incoming ring stage.

    That's a very interesting advice. Thank you.

    Does anyone know where I can find the camera access logs in the system? Thank you!

  • Google Duo will trigger the selfie camera from starting upon incoming video call.

    Even if you didnt accept the call.


    This is the native Google Duo app-behavior. It is calling for the selfie camera before call-acceptance.

    Now I do not know if it was Duo doing this, but maybe it can help you narrow down.

    I don't ever use google duo, and I don't have any contacts in there, and I never even opened that app, and don't know anyone who ever used it.

    I checked the logs, and there were no missing calls from google due - I don't even have an account there.

    I swear! This was the freakiest thing that ever happened, I saw it with my own eyes! My camera rotated up, stayed up for a sec, and then rotated back down! The screen NEVER ever even blinked! That's the creapiest part!!! That the screen didn't even turn on at all. It stayed off, and locked for the whole time!

    I think you should denied all the camera permission and see if it happens again ...

    denying camera to everything is not a solution. The solution is to find the source. Can someone please tell me where are the camera logs?

    Although, I have a strong feeling, it's a vulnerability in the android itself, so if someone was able to quickly check my camera, they def had access to the logs as well. Not good... :\


    I checked the Camera code, and it seems that the built-in camera only programmed to Log errors only?

    Not a solution but a path to find which app did that. I've never seen this behaviour on my phone.

    We have the same app list except for whatsapp and twitch.

    I know. It never happened to my phone before either. I like Zenfone 6 so much - when my camera is on, and wants to point at me, it has to make a sound, and motion, unless the phone is upside down, of course. That's really cool. On the phones with static cameras - you just never really know, for example...

    I don't think I'll ever find out what caused it singlehandedly.. Mainly because the camera doesn't log accesses, and requests, only errors. Wait... What if an error actually happened in that moment? Where can I find the error logs on Android?

    Okay I found it, I need to use logcat either via adb, or via an app. I looked into it, and all logs are empty, apart from the stuff that only happened maximum 2 minutes ago.

    The app logcat can let you log actually any desired app. So, at this point it's the only thing I can do - use the logcat to log the com.asus.camera app while trying to avoid using it completely, and see what's gonna happen in the future. The logcat can be manually configured to log everything that's happening to the camera, not only errors. That's what I did. Now I'll just not use the camera at all, and see, maybe I'll get lucky.

    Thank you guys! If I find anything I promise, I'll write about it here!

    It's an interesting case to me. I hope you'll find an answer with some tools given by ASUS staff when they'll see this topic.

    Maybe we'll never know ...


    But I have some questions which can be stupid.

    Where your phone was charged ? On a table ? Screen facing down ?

    Did something block the proximity sensor ? A paper or a book for example ... Because as long as something is in front of this sensor on the top of the phone, the screen stays off even if it's triggered to turn on.

    My phone was charging on a charging stand, that keeps phone in a vertical position

    Okay, hope you'll find out !

    I am writing you to ask you, if there is a log, or any way to find out which processes have access the camera in the last hours.

    Check Usage statistics:

    1. Dial *#*#INFO#*#*
    2. Select Usage statistics
    3. Sort by Last time used

    Or open My apps shortcut from Play Store, select Installed, sort by Last Used.

  • woAwoA Level 1

    It shown me that the camera was used 37 minutes ago. That's all...

  • _jis__jis_ Level 5

    If you checked Usage statistics then you should say that the Camera application was used 37 minutes ago ...

    I've never seen this behaviour on my phone.

    I've checked your screenshots and I don't have installed Messenger, Twitch and WhatsApp. So if I were you, I would limit my search for culprit to these three applications.

    I bet it's the facebook corp, man...
