App crashes/restarts when rotating app on DFU screen

[jmaha]

This bug has been present for a long time. I noticed it's still there in the latest release 2.7.7.

If I do these steps, the app will exhibit a strange almost-crash back to the Scanning screen with all filters reset:

• Connect to a device advertising the Nordic DFU service
• Select a firmware image to install
• On the DFU screen that shows the graphical depiction of how much space the Application/Bootloader will take up, CPU info, and the Start/Cancel buttons, if you rotate the screen (which I frequently do to attempt to read a long filename to make sure I chose the right file), the app restarts without fully crashing: the screen goes black briefly, and then restarts back at the Scanning screen with all filters reset. Very frustrating when I was just trying to double-check a filename before starting DFU.
