My A30i is new, has been working great on my food plot. 100 or so pics every 2 weeks. Been 3 weeks now, checked today, only took 7 pics and the last one is completely black. I turned it off, back on, would take a pic when I waved in front, walked in front, no pic. Set on video, seems to be working. Batteries are DuraCell at 98%. What’s up with pics ?
