One of the rumors suggest Google's upcoming Pixel device will cost as low as $400, and many rumors have suggested that it'll come with the same acclaimed camera as the Pixel 3.

More details on Android Q — Google's next big update for its mobile operating system.

Android superfans and early adopters have had access to the Android Q beta for some time, so we'd expect announcements for the upcoming big Android update to include details of existing initiatives, like improving privacy settings and transparency in Android and Android apps. 

We'll also likely hear other things that Google wants to highlight about Android Q, like streamlining and improvements.

Google might say something about foldable smartphones.

If it's going to mention Android Q, it's reasonable to expect some kind of mention about foldable smartphones. 

Google worked with Samsung to make a version of the current Android Pie OS that supports the Galaxy Fold's foldable design, and foldable support is coming natively to Android Q.
