I'm experiencing the exact same front camera issue since day one. It flickers intermittently, about 10% to 20% of the time, and occasionally displays a constant blue screen.
Once, it even froze on a blue screen. Restarting the infotainment (long press home button) didn't fix it so can confirm it's NOT software. I easily managed to fix it by physically wiping the from camera so it is probably a loose connection.
While it still flickers occasionally, it's mostly functional. I couldn't reproduce the issue at the dealer, he advised me to monitor it and bring it in if it worsens or becomes consistently reproducible, which hasn't happened yet, so I'm managing for now.
