did u take a couple photos to make sure? i exchanged mine for a brand new tello yesterday and on the 2nd photo EIS malfunctioned... im at a loss as to what could be happening, maybe a bad batch at the store...
update: Guys please check your tello's, after taking a photo tello looses EIS until I turn it off and back on. My place of purchase did an even exchange and right out of the box EIS malfunctioned after taking the 2nd photo. I'm 99% convinced it's a firmware bug.
Emails are going back and forth... I requested to return to place of purchase for a replacement. ryze only does ups ground shipping which is 7 days to CA. thats 3 weeks without my tello again... btw tello with tellofpv is a great setup otherwise.
