One of my goals was to do a bunch of time-lapse shots, taking photos every few seconds and then making a video out of them. They marketed this feature (take a photo every X seconds) quite a bit, so it was definitely a selling point to me.
I discovered the bug a few weeks after owning it, right before a big vacation I was hoping to record. It would take about 8 or 9 photos and then lock up. I couldn't turn it off or stop its capture. When I plugged it into my computer, I saw that there were hundreds of empty folders. I tried power cycling it by taking the battery out and putting it back in. I also wiped out the memory card both via the computer, as well as selecting the 'delete all' option on-camera, all to no effect. I emailed them, and their response was:
> Hi, Do you take many time lapse pictures? What may have happened, is you may have encountered a known issue with our current firmware, in which the camera is no longer able to save files after it has taken 9999 images. Could you please let me know what the name of the last successfully captured image was? If this is the case, we would need you to send in your camera, and would reflash your firmware to fix the issue.
So I had to shell out $20 in shipping and mail my (brand new) camera across the country for it to be reset. I wasn't able to record the trip I took. Still irks me today that they were selling cameras with a known, software-limited, number of shots you could take with them before they had to be sent back.
If their QA department took a photo every 1 second (as their product was advertised to be capable of) it would take 2.78 hours for them to discover this bug.
