But before we get to the good stuff, you should know how unlocking faces on both phones works, as they differ slightly. Both the iPhone (any model X or later) and Pixel 4 use an infrared sensor to project points onto your facial features, which are then used to create a unique depth map of your face. But – and importantly – Google's approach also depends on a small chip in the phone that detects your movement using radar (eg, picking up the phone) and passes your hands to the point projector to do the unlocking work.
You can not unlock the Pixel 4 without the help of Motion Sense. And you can not unlock the iPhone without swiping up from the bottom of the screen. In certain situations, you can slow down both control points.
In four typical scenarios, I tested which face unlock is easier to set up and which phone is faster and more convenient to use: Lift the phone to your face, lean over the phone to unlock it when seated on a table Unlock the phone when you lie down and use it in complete darkness. Here's what I found out:
The Better Setup Process
It's just as easy to set up the face unlock on the Pixel 4 as on the iPhone (I used the). Both control the first face scan and give you a goal while slowly turning your head in a circle so that the phone can scan all of your angles. Delete the blue blocks for Google and fill the circle for Apple.
Pixel 4's setup process slowed me down with false mistakes when I apparently did not turn my head properly. Apple lets you scan your face twice, but it's quick and painless. All in all, I prefer the method of the iPhone. (Scroll to the end to start the complete setup process.)
The Lift-to-Unlock Method (Screen Off)
Pixel 4 wins this round for sheer ease. If you've activated Motion Sense, a radar-based gesture control built into the phone, the device unlocks when you pick it up, lifting it to your face. Wiping is not required.
Here's how it works: A radar sensor detects that you are picking up the phone, activating the screen, and preparing the system to scan your face. It then calls the face unlock software, which lets you scan your face and determine that you are using a point projector. The whole thing takes about a second (of course it depends on how fast you move).
The iPhone process is not difficult, but takes longer. You can lift the phone at once to wake it up and unlock it. However, you still need to swipe up the lock screen to get in. This is a fast movement that can take about the same amount of time as Pixel 4, provided your reflexes are sharp. It only takes one step, and if you do not swipe up from the bottom of the screen, you waste time trying again.
If you are too lazy, tired or busy Pick up a phone lying down to unlock it. You may want to wake it up by leaning over and looking at the front-facing camera. This works great on both Pixel 4 and iPhone 11, but the experience of Apple is more consistent. While the Radar of Pixel 4 is really good at detecting the movement and presence of my hand reaching for it, it is a lot less good in the registry of my head hovering over the display. After much trial and error I've found that you can hold your hand in the direction of the sensor (but not too fast) and then prevent yourself from unlocking. Otherwise, hovering alone is usually not enough to trigger the face scan, even if you first press the Lock key.
The iPhone 11 needs to press the lock button to wake up, but once you do so, it quickly registers your view and only requires swiping down to get in. Overall, I have had more success unlocking the iPhone that way.
The routine of dropping off
How do I use my phone when I lie down – on the couch, when I wake up, name it. Depending on whether you fall on the side or on the back, one of these phones will definitely unlock better than the other.
The Pixel 4 reacted very much to me picking it up and keeping it supine over my face. but much harder to reach when I lay on my side, especially when my hair fell on my face. The iPhone was better able to make eye contact than I was on my side, but you still need to wipe it from the bottom up, which is a lot more precarious if you hold it right over your face because it means you only Her face holding heavy phone with one hand.
Unlocking the Phone in the Dark
Both phones worked flawlessly in a pitch-dark room, as long as I held the device in front of my face. The Pixel 4 was also easy to unlock when I stopped and lifted my hand from the bottom of the phone – it does not work if you do it too fast. This action triggers Motion Sense to activate the face scanner, and then the sailing is smooth.
Which one is faster overall? Pixel 4 and iPhone 11 Pro were neck and neck until you add all the factors along with swiping and waving. Theoretically, the Pixel 4 should be faster because you do not have to touch the screen at all. However, if you need to trigger Motion Sense first, it may take just as long as a short movie on iPhone 11.
This section tells you how to set up the face unlock on Pixel 4 and iPhone 11. Weigh in ouron everything we like and dislike about Google's new phone.
How to set up the Pixel 4 face unlock
Go to Settings > Security > Face Unlock . Choose your unlocking method for the backup screen, for example: For example, a pattern, PIN, or password. Then select the type of information to display on the lock screen: all notifications, some or none. Click Next and then Start.
You will see your face surrounded by a spherical grid of blue blocks. You are done scanning when you have "uncovered" all the blocks by turning your head in all directions. That's it. Once you've confirmed that you've made all the settings, you can restrict the use of face unlocking to unlocking your phone, signing in to apps and authenticating mobile payments, and skipping the lock screen.
iPhone 11 Pro Face ID Setup  Go to Settings > Face ID and Password . Perform the procedure to set up your passcode, and then select Set Face ID . Click First Steps to scan your face for the first time. You see your face framed and have to slowly move your head in a circle to complete the first scan. They will do this again.
After confirming that Face Recognition is set, you can disable the iPhone Unlock options that use Face Recognition for iTunes and the App Store,and Password Autofill.
