It was a long time coming, but Android finally has built-in scrolling screenshots, and they come courtesy of Android 12.
Now that extended screenshots are integrated into Android by default, you can delete those third-party apps you've been using in the meantime, which were necessary on Android 11 or lower, whether stock or thinly skinned by OEMs.
However, if you own or have owned an Android device from a third-party manufacturer with a customized OS, you might be surprised that scrolling screenshots are new to Android. That's because smartphone makers, for some time now, have implemented custom versions of the tool in their overlay software. Samsung has "scroll capture," LG has "extended capture," Huawei has "scrolling screenshot" and "scrollshot," Motorola has "long screenshot," and the list goes on.
Heck, Apple's iPhone and iPad have even been able to capture images of entire webpages in Safari as PDFs since iOS 13.
On a Google Pixel running stock Android, or with an almost-stock experience like some Android One phones have, scrolling screenshots is an exciting new addition. Now all Android smartphones running Android 12 have the native capability to take scrolling screenshots. An OEM would have to block the feature in their skin if they don't want it or would rather use their own capturing tool.
