FAQ: How to do a scrolling screenshot on the POCO M3?

Just do a normal screenshot either by pressing the Volume Down button and Power button at the same time for a second or swipe down with 3 fingers.

Next, press the Scroll button on the generated thumbnail in the upper right corner of the screen. It will then automatically and slowly scroll to the bottom to capture a long screenshot.

Tip: Instead of waiting for it to scroll down automatically, you can actually swipe down manually to have the long screenshot done faster.
