Both EFB's locked up while in precipitation static while descending in clouds on [RNAV arrival]; Copilot was flying. We were deviating for rain showers when both EFB's froze. Displays still worked; but no inputs on screens worked. Got out of seat to get paper backup charts stored in galley area. Bad time for major distraction.
A300 Captain reported both EFBs froze up on an RNAV arrival; forcing the Captain to leave his seat to retrieve paper charts.
