At the moment, I regret buying this camera. It has been little more than an annoyance. This is firmware rev. 1.13. I just finished a three hour time lapse run. Oops, no file, no response to setup button, no response to anything. Time to pull the battery yet again. File lost even on laptop. So far I've managed one 14 second 4K video (looked nice). And that's it. The quick start manual is virtually worthless. There's nothing that can't be guessed at or explained in better detail on YouTube. Fortunately, I downloaded the 1.15 OM, which is more helpful. Why are there four LED's? One is for charging, one is for the WiFi, what the rest do escapes me. What is the largest SD card accepted by the SJ7? 128G (yes 128G can be formatted to FAT32)? 64G (ditto)? 32G? It's not documented in the Products pages, not in the QS, and not in the OM. It's simply not documented in a way that's easy to find. The app... too bad BT doesn't carry the data and leave the phone connected to the Internet (would make firmware updates easier). Otherwise, the UI is... well, the app didn't get 3.1 stars for nothing. I like the build. Except the lens is unprotected. There's no slightly raised ring to protect the lens if the camera is set face down on a flat surface. I understand electronics. I've run computer centers, I've taught at the university level, and, heck, I hold a ham radio license. I'm stuck with the camera for now. If I hadn't used Amazon, I'd be in the store, returning the thing.
