When I access to the TWRP (version 3.2.1-0) and select the Wipe button, the screen says:
Wipes Data, Cache, and Dalvik (not including internal storage)
Most of the time this is the only wipe that you need
But the description of the slider says:
Swipe to Factory Reset
Is Factory Reset the same with Data, Cache, and Dalvik wiping? What is the difference between the data it is about to wipe and internal storage?
