Android/Screenshots

Android has a keys combo for screenshots; press the hard volume down and power buttons at the same time, and hold them for a second.

On XO-4 the hard volume down is mapped as game button "X" on screen pad. So the screenshots combo are

"Power button" and "Game button X" press at the same time and hold them for a second.

tips:

press power button sightly earlier than "X" button would be easier to trigger screen shot.

For old build which does not has Game button mapped as volume down, please following this alternative to take shot.

As a alternative there is a binary which can do the some thing via adb shell

adb disconnect && adb connect 192.168.XXX.XXX
adb shell screencap -p /sdcard/screen.png
adb pull /sdcard/screen.png
gimp screen.png
