How to create a stackshot
Reproduce the issue, freeze, unresponsiveness or wait until it happens again
Press and release the power button and both volume buttons at the same time.
This will create the stackshot file. A few notes:
There is no feedback whether the stackshot was created successfully, so it’s best to press all the buttons two or three times to be sure. Each time will create another stackshot file.
On devices without a home button, creating a stackshot will take a screenshot as a side effect. You can delete this screenshot.
On devices with a home button, creating a stackshot may lock the screen as a side effect. Please unlock the device and continue.
