Good day.
When you close the keyboard, a white trail stretches behind it, all heavy processes are brought into service, for the sake of the test it turned off everything - and work with the database and the network .... the same result

    Imagine the process:

     Клавиатура закрывается плавно( уезжает вниз экрана на определенное количество пикселей в секунду ). Интерфейс же приложения перерисовывается( и, возможно, масштабируется ) в соответствии с новым освобожденным от клавиатуры пространством. Перерисовка происходит быстрее, чем заезжает клавиатура( минимум, в 10 раз ).

    One of the options is that you can have a custom firmware (not “factory”) on your device, in which the standard keyboard is replaced with a more resource-intensive one (as a result of the firmware modding). And so the animated process of "leaving" the keyboard "eats" too many computing resources. In this case, try to replace the keyboard or at least customize it somehow.

    The second option is to look for irregularities in your code! Sometimes, finding any, you wonder: how the application worked at all and did not fall from the same OutOfMemory, for example.

    • it was tested on several devices, for the sake of the test it cleaned up all the heavy processes, there are not even warnings because it is strange - gadfil
