Hi, this issue has a relation with #71. We found failures similar in the MainActivity: <div id="ladoalado" style="display:flex;justify-content:center;"> <figure id="container">Before and after double screen rotation<br> <img src="https://user-images.githubusercontent.com/3637419/159147708-d8a47730-95c0-4c04-91ac-17e9bab2e987.png" width=20% height=20% > </figure> <figure id="container"> <img src="https://user-images.githubusercontent.com/3637419/159147706-7e152d63-45e0-4780-b65a-d5af2298d4fd.png" width=20% height=20%> </figure> </div> <div id="ladoalado" style="display:flex;justify-content:center;"> <figure id="container">Before and after double screen rotation<br> <img src="https://user-images.githubusercontent.com/3637419/159147752-ebd21f1a-e87d-42fb-94fd-0c838e825ddc.png" width=20% height=20% > </figure> <figure id="container"> <img src="https://user-images.githubusercontent.com/3637419/159147749-7dff99ca-b68a-47d0-b4e6-334e29a1564e.png" width=20% height=20%> </figure> </div> <div id="ladoalado" style="display:flex;justify-content:center;"> <figure id="container">Before and after double screen rotation<br> <img src="https://user-images.githubusercontent.com/3637419/159147796-3314dc1d-3f84-400b-a588-6deb19ed2085.png" width=20% height=20% > </figure> <figure id="container"> <img src="https://user-images.githubusercontent.com/3637419/159147795-35ded7aa-5be9-4469-bb28-6892460053b6.png" width=20% height=20%> </figure> </div> Note: - 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.
