Following the release of the first Android 12 developer preview last month, Google has now released the second developer preview. Although the new developer preview gives us a sneak peek at new Android 12 features, it also includes evidence that a Pixel phone with an in-display fingerprint scanner is in the works.
On the contrary, the new classes are initial pieces of evidence implying a Pixel phone with an in-display fingerprint scanner might launch soon. It is not that we haven’t seen any Google hardware leak via Android’s source code before. However, we suggest you take this information with a grain of salt and wait for an official announcement.
