It is rumored that the next Google Pixel 4 and Google Pixel 4 XL will launch with 90 Hz OLED Display, according to a report published about a month ago. And now it seems to have been confirmed by a comment in the Android 10 source code.
XDA developers have searched the source of the latest version of Android Google recently released and found several interesting reviews of the ad’s refresh rate. One of these methods describes the content-based fps discovery, while another describes the implementation of an overlay that shows the device operating at 60 Hz versus 90 Hz.
However, these alone would not be evidence of their relationship with Pixel 4 because Google is constantly expanding AOSP code elements to accommodate the growing number of devices from many manufacturers. A comment in a commit that has since been deleted (but you can still access it by browsing history) makes things very clear.
Here is what it is. The code in question adds an on / off indicator to switch to 90 Hz mode. It is intended for temporary use only until the appropriate solution is implemented (which happened shortly afterward). However, the main conclusion is “The switch in the settings should only be available for P19 devices”. P for pixels, 19 for the year … and you get the point.
After further investigation, it became clear that Google intends to make the refresh rate overlay available as a developer option. The level is displayed below the clock in the status bar in the form of a red rectangle for 60 Hz and a green for 90 Hz. This is useful if you want to check if an application is running at 90 Hz or not. Finally, Google also wants to know when a video is being played so Google Pixel 4 can automatically adjust the refresh rate.
The Google Pixel 4 should be equipped with a 5.7-inch 1080p + OLED screen, while the Google Pixel 4 XL should have a 6.3-inch 1440p + display. The smallest model should have a battery with 2800 mAh, the XL version instead with 3700 mAh. Both should have the Snapdragon 855 chipset and 6GB of RAM and of course run Android 10 from day one.
For the first time, we also integrate two rear view cameras in the pixel area, with the secondary sensor being a 16 MP telephoto lens. On the front, the top frame is wide to accommodate face recognition devices and a solos radar for Motion Sense air movements.
