I updated to firmware v4.0 from v3.0 and after that, I reset the camera settings and the camera defaulted back to NTSC. When I wanted to change it back to PAL (I live in Europe) the option to change it was gone... And on top of that, after the update the replace batteries stopped showing the percentage... Can't guarantee the safety of this battery bs.. I use Patona Premium. On v3.0 everything was working fine.
