Мой МТС Restyle Challenge

The online internship DesignLine Boost from Creative People and Humble team has started. Yesterday, 500 participants out of 700 met the deadline, completing the main test task and an additional one (a screenshot of which you can see) in two days.
The task of the second task: to update the UI style of the application "My MTS". The text and functionality should not be changed.
This is my fastest Behance case - 2 days. Visual solutions were shown and described. Link to the case:
