◆ External appearance comparison between Pixel 3 and Pixel 4
From the left, Google Pixel 3 (5.5 inches), Google Pixel 4 (5.7 inches), Google Pixel 4 XL (6.3 inches). In Pixel 4 and 4 XL you can see that the bottom edge of the bezel is narrowed.
The top edge of the bezel. Pixel 3 on the top, Pixel 4 on the bottom, Pixel 3 is dual camera (8 megapixel standard camera & wide angle camera), Pixel 4 is equipped with only 8 megapixel wide angle camera, but the thickness of the bezel is almost the same.
Pixel 3 (top) and Pixel 4 (bottom), although the screen size is different, the dimensions are exactly the same at 147.1mm x 68.8mm, so they overlap almost perfectly. This is a picture from the top to the left side of the screen. On the side of 3, there is a SIM card slot on the side of 4. In addition, there is a difference in the side part 3 is smooth, 4 is matte finish.
As for the power button part, 3 is the same as the main body color and 4 is white.
Bottom part. The USB Type-C port and SIM card slot are 3 (top), and the USB Type-C port and speaker are 4 (bottom).
The biggest difference between the two terminals is the back. Pixel 3 (left) has a single rear camera, and the material of the parts is different between the upper and lower parts of the camera, with the matte finish on the bottom. In addition, a fingerprint authentication sensor is mounted on the upper side. On the other hand, the back of Pixel 4 (right) is a single piece of gorilla glass 5 except for the protruding camera part, and fingerprint authentication is abolished.
◆ New face recognition technology with Pixel 4
“Face Unlock” was installed in Pixel 4 instead of fingerprint authentication. Unlocking function by face authentication is equipped with
Face authentication can be set at the time of initial startup setup, and can be set at any time by selecting “Face recognition” in the “Security” menu later in “Settings” even after skipping.
When you register your face, you can wear glasses or sunglasses with a light-colored lens.
Follow the screen and turn your face up, down, left, and right while holding your smartphone.
Registration is completed in less than a minute.
Now you can unlock it by simply pointing your face at the device. As explained at the time of registration, the presence or absence of glasses is not a problem at all. 'Register with glasses on and unlock without glasses' 'Register without glasses and lock with glasses on' Both “Release” were OK.
Its usability is “as if no lock is set”. Basically, when you use a smartphone, you see the screen, so the front camera is facing your face. When you press the power button in that state, the camera recognizes your face and unlocks it when you release sleep. With fingerprint authentication, there was a `` waiting for release '' that the fingerprint was recognized and the lock was released after the PIN code input screen was displayed, but it is more convenient than Pixel 3 because it does not exist Impression.
In terms of accuracy, I felt a balance between the ease of use that allowed for changes due to decorations and makeup, and the security aspect that would prevent it from breaking through with a similar face.
For example, when trying to unlock with a mask for colds and hay fever, the lock could not be released when the mask was applied to the nose, but it was locked when the mask was lowered to the bottom of the nose (the part covering the nose) Has been released. On the other hand, the face authentication registration with the mask on could be registered if it was lowered to the point where the nose was visible, but in this state the lock could not be released when the mask was removed.
Also, the authentication in the dark place is perfect, and even with the setting of “brightness level 0%” where the brightness of the display can not be expected much with the surroundings almost dark, the lock was released properly. As for “Funny Face”, if you make a funny face that is distorted with facial expression muscles, the lock is released even if you open your mouth, but you can use your hand to touch your cheeks as long as it does not affect the camera. The lock was not released when it was lifted up to make a funny face that changed the shape of the eyes.
In addition, sukekiyo's mask could not be registered as a face in the first place.
ICEO, a doll, is also out.
Because the eyes, nose and mouth are out, the mask (balancing cap) could be registered. In this case, the lock cannot be released if the cover is removed, so there is no fear that the identity will be revealed because the face is unlocked.
On the other hand, since
◆ Difference in benchmark score between Pixel 3 and Pixel 4
Pixel 3 and Pixel 4 have different specs such as Qualcomm Snapdragon 845 octacore and Qualcomm Snapdragon 855 octacore processors, and 4GB and 6GB of memory. I compared the difference of this with the score of benchmark application Geekbench 5 .
First, Pixel 3. The CPU benchmark score is single core '521' and multi-core '1857'.
The score of Compute was “1620”. Benchmarking was also performed when Geekbench 5 was released, but the score of the CPU was almost the same, but the score of Compute is greatly different from “643”. The only major change in Pixel 3 is the OS update from Android 9 to Android 10.
Next is Pixel 4. The CPU benchmark score is '641' for single core and '2387' for multi-core.
And the score of Compute is “2231”. All scores exceeded Pixel 3.
In addition, Pixel 4 XL with the same processor and the same amount of memory as Pixel 4. The CPU score is single-core “751” and multi-core “2581”.
On the other hand, the score of Compute was “2099”.
Following the main unit performance, I took it outside and compared the camera performance with the Pixel 3.
