Found a@facebook#securityprivacyissue.
When the app is open it actively uses the camera.
I found a bug in the app that lets you see the camera open behind your feed.
I unlock the phone, and theres the video on@Instagramplaying away.
Is this an app bug or an iOS bug??
However, the issue was not found to be present on devices running iOS 13.1.3.
This sounds like a bug, we are looking into it.
We recently discovered that version 244 of the Facebook iOS app would incorrectly launch in landscape mode.
We have seen no evidence of photos or videos being uploaded due to this bug.
Were submitting the fix for this to Apple today.
Its unclear when the updated Facebook app will be made available to iOS users.
Meanwhile, it’s advisable to revoke Facebooks access to the camera until the problem is fixed.
you’ve got the option to do this by going to parameters and heading to Facebook option.
Tap Facebook and under Allow Facebook to Access, turn off the switch beside Camera.
