After working on prototypes , Google reportedly plans to release a foldable Pixel in 2022. According to 9to5Google's deep dive into the current Google Camera APK, the phone is codenamed Pipit. While there aren't many concrete details about what the foldable looks like or how it functions, the APK offered some insights into the Pipit's camera setup.
The Pipit (or Pixel Fold, or whatever it will actually be called) is said to use the same 12MP IMX386 ultrawide sensor as the current Pixels, as well as two front-facing 8MP IMX355 sensors. There's likely to be one of those on each side of the body so folks can take selfies whether the device is folded or unfolded.
It makes sense that the main camera might not be as powerful as the one in the Pixel 6 lineup. Those phones have to give the camera sensors enough room. Size is a bigger concern on a foldable than a slab-style smartphone, given it's twice as thick when its closed. So, camera sensors with a slimmer profile might be preferable for Google in this case.
Elsewhere, the APK includes the term “isPixel2022Foldable." That's a decent indication that Google plans to release a foldable device next year, given how Google has used similar terminology to refer to previous Pixel models.
