The latest Google Camera app update allegedly hints at new 24fps feature
The XDA contributor Mishaal Rahman claims to have obtained and torn down the most up-to-date version of the Google Camera app (7.3.017). He asserts that strings referring to a new video-recording option have been added to this software. They would apparently allow compatible hardware to do so at 24 fps, whereas 30 fps is the best that can be done today (on Android).
Therefore, it is possible that some 2020 phones could support this state-of-the-art feature. The new Google Camera APK analysis has also reportedly resulted in the possible confirmation of the Pixel 4a series' code-names. Earlier leaks had suggested that the names "sunfish", redfin", and "bramble" were associated with these phones.
The same monikers have allegedly appeared in the updated camera-app code from Mountain View, in conjunction with strings that start, "pixel_20_mid_range". This seems to suggest that they refer to the Pixel 3a and 3a XL's successors, some of which are thought to run on the Snapdragon 765 SoC.
