Attention Android users:

If you experience regular or repeated crashes, please install Scoop from f-droid. Scoop monitors app crashes and captures a stack trace, which contains information that can be extremely helpful for developers. If Scoop detects a crash, please file a bug report and include a copy of the stack trace with it.

As per the instructions, non-root users must run the following command on the device in order to enable Scoop. You do this from a desktop using the adb shell command, or from the device itself using a terminal emulator app such as Termux or many others. Neither method requires root.
