The ambient light sensor dims the display brightness at night and raises it in daylight, not the opposite as you mentioned.

Face ID doesn’t compare 3d scan of your face with original 3d scan. It actually compares it with some recent 3d scan of your face. Hence it can learn and adapt how your face changes over time (gaining weight, growing mustache etc) I know it’s a nit pick tho. It’s a great video overall

9:11 There’s a little misinformation here. It’s is not checking for just your face, but also your eyes should be looking at the phone. Hold your iPhone to your face but don’t look at it. It won’t unlock your iPhone. Once you move your eyes to your iPhone, it unlocks. This is why it is called “Attention Awareness”.

3:24 you not only said it wrong but also showed it wrongly, ambient light sensor is to make the display dimmer in the dark, so it doesn’t blind you, and brighter in the light so you can still visibly see the content on your screen

You clearly put a lot of work into this video. Very helpful info. Some of the comments noticed some info that needs clarity but I still think you did an amazing video here

[keepsearchingk]

So refreshing from all the tech channels out there 🎉

[rafaaromero]

Underrated Chanel! I LOVE the editing skills, video quality and audio!

[onewildviktor]

This content is informative and well thought. Keep it up!

[Hey-Yaz]

This was very well explained. Thank you!

[FernandoBaldrich]

I found your channel thanks to this video, you explained it really well and I love the editing! Very easy to follow

[Alex-tuvu]

9:13, actually the reason is another setting called raise to wake where the phone turns on when the motions sensors detect an upward motion of you picking up the phone

[xoticxd]

Was looking for this explanation for long time thanks

[miketech]

Randomly got this in my recommended videos. Don’t normally like any videos but this one is exceptional. So I hit like.

Here justifying your purchase cause that shot with the security camera was so cool 😂

[SuperWearethed]

This is good content! Never would have guessed that your channel is under 10k followers.

You just earned a follower! Good luck going forward, seems like you have a bright path!

[rphlmcosta]

Your night vision shot was DOPE! Great and fun video!

[DoubleATech]

This is by far the most detailed but also easy to understand video I've seen about Face ID since it launched!

[tubeyou]

Wow, you only have that many subscribers? I thought you have millions. This is really high quality content.

[LalitDevraj]

You've done it again!! I'm literally looking forward to the 1 video popping OFF on your channel and the rest will literally be historyyyy

I legit want you to take a screenshot of what your views look like today because once the drill down starts by folks, get ready to exponentially grow/go to the moon haha - seriously, really amazing videos/concepts) editing and everything 😊😊

While watching this video I didn’t pay attention to how many views or subscribers you had and I had expected you to have around 100k subscribers. So I was surprised when you had only 7k, but this is a great video and keep up the good work.
