Screen Flash after pressing a combination of key

Device- MicroMax Android One
Today, I noticed screen flashed when I pressed the following combination of keys.

1. Turn off your phone
2. Press volume up key then volume down then power button.
( do it in the order)(keep pressing the volume up key and press volume down key, keep holding volume up and down keys and press power key)

3. Now keep pressing three keys for 5 seconds.
4. Remove your fingers
5. Screen will flash after 1-2 seconds.

What does this combination of keys do? Apart from flashing the screen.
