The app crashes and exits by itself while accessing the "Frequency Log" feature when changing the rotation to landscape mode and back to portrait mode. #113

Expected behavior

Supposedly, when accessing the "Frequency Log" feature and when changing the screen rotation 2 times, the app will not experience errors.

Actual behavior

When I click on the "Frequency Log" feature and after being on the Log frequency setting page, I accidentally changed the rotation to landscape mode, and when returned to portrait mode again, the app crashes and exits by itself. I have done the repetition, but the error persists.

How to reproduce

  1. Install and Open apps
  2. Next click the feature "Log Frequency"
  3. If the log frequency settings page is open, change the rotation to landscape mode, and then return the rotation to the portrait mode. Then you will find the error as I experienced.
