I have a new M10-P and have installed latest firmware, 12/2018, with fast Lexar 128GB 1000x memory card. The other night I went out to photo sunset, but the MENU button would not work, managed some pix, removed battery, switched on and off a few times, finally all OK. I have NEVER had an unreliable Leica (or Nikon), and for $8000. Tonight I went to make a picture and the LIVE button wouldn't work, nor the MENU button, and the display of ISO was weak and dim (fresh battery). In a few minutes all working OK. Has anyone else had similar troubles with M10 or M10-P? My Leica Q and digital M never gave me a bit of trouble.
