After being released to the Android open source project code, Google's software engineers revealed some information in the comments above.

At present, code changes mainly focus on fixing the problem of Google's memory error detection tool, which is called "KASAN". Unfortunately, this technology will only be applied to Google's next generation mobile phones, that is, Google Pixel 4 will be released this year. The employee said that Google Pixle4 has been tested.

Through a quick reading of these comments, Google's initial plan is to start bug fixes on Google Pixel 3 to ensure that the machine works properly. Once this work is completed, employees will begin to conduct compatibility testing for the future Google Pixel 4.

It is almost six months away from the next generation flagship Pixel 4. At present, we speculate from the previous exposure rendering that Google Pixel 4 will use a front and rear dual camera design, the front panel is similar to Samsung's hole digging screen, and the rendering does not see the fingerprint identification module, and there is no component in the front that can hold structured light, so it is speculated that Pixel 4 will use fingerprint under the screen, It is not known whether the fingerprint is under the optical screen or under the ultrasonic screen.
