X-S10 menù button unresponsive

[zatarra77]

Hello, 

I'm facing a strange behavior with my brand new X-S10. When I turn on my camera after not using it for several time, my menù button is a bit unresponsive and sometimes (not always) I have to press it 2-3-4 times before entering the menù.

While using my X-S10, the button starts to work as expected (1 press --> entering menù)

I am not able to understand if it a "normal" (but strange) behavior (maybe some kind of energy management or loading functions after turning on) or if my camera is faulty...

Please, could you write your thoughts?  

Best regards

Carlo
