My biggest issue with burst mode is that I can't get to 99 shots. The phone will randomly shut off after any number of pictures. The most I got it to take was 54. I have the feature that only lets you take 20 photos in burst mode turned off. Not sure how to fix this. It's not really that big a deal, to be honest, but someday, it could cause me to miss a picture that I want.
The other issue is that the camera definitely would not be able to take 99 shots in 20 seconds or whatever the claim was. The time it took 54, it took about 20 seconds.
Like I said, not a big deal at all, just curious if anyone knows how to fix this. I should try my wife's out and see if her's is the same.
Other than these two very small issues, I have not had a problem with the phone. I love it. Upgrading from the Hero, this phone was worth the wait.
