The process is a bit complex. If you want to take a screenshot, press the home and power buttons at the same time (that should work).

You can redo a challenge like this:

1. Set your date on your device ahead one year, but you must have the injustice tab open

2. Then switch to it. Once it loads, it should say the previous challenge has expired.

3.  Switch your time back to normal. Then go back to injustice and it should be reset
