Data loss while using the app (an image appears after double screen rotation)

[davirec]

When I perform these sequences of events, an image appears after double screen rotation:

1. Open the app
2. Tap in the hamburger menu
3. Tap in New Game
4. A screen similar to this will appear:

Before rotation:

5. Force the pause from the activity and then return to the activity (double screen rotation). Note that an image and two buttons appear after double screen rotation.

The expected behavior is the return to the state of the previous image.

However, an image appears after double screen rotation.

After rotation:

Note:

• The pause from activity(1) can be performed in several ways. We suggest using a double screen rotation (starts in portrait, goes to landscape, and back to portrait) with this function previously enabled in the smartphone.
• Double screen rotation: It is executed twice to reach a state that should be exactly the same as the screen before if no data loss occurred.
• A data loss problem occurs when data is accidentally deleted or state variables are accidentally assigned with default or initial values.
