On some other thread i mentioned that temperature might have something to do with wifi-problems. Last summer was very hot in Finland and i could not watch/transfer anything. I do get connection on first try for over 90% of times (around the year), it loads map* and thumbnails just fine etc, but after that, trying to watch videos it gets stuck way too often. In summer it really was basically 99% fails. Now, in the early winter with temperatures just above freezing, it fails in maybe 60% of cases. It might work just fine for downloading file or two and fail after those, or fail the first try, but let me dl multiple videos when going back to thumbnail list and selecting same video again.
Strangest thing for me is that transfer speed (when downloading file to phone) is always quite stable ~2,9 MB/s. There is no in between, it just tries to load video for ever without any results or at that ~2,9 megs per second. If i try to just watch the file on roav-app, it stops to cache constantly. Plays only for 5 seconds and then caches for 10 or something. File size divided by video length gives ~2,4 MB/s, so it should be possible to watch without cache-pauses. I haven't clocked actual transfer times and can't come up with reason for why there would be any difference between watching in app and downloading the whole file. If and when the transfer protocol etc are the same, transfer speeds showed on the screen can't be true.
Wifi was my main reason when selecting this camera. I'm fighting my urge to keep second memory card in car to swap in when i think i have recorded something worth saving, as with only one card, i need to get it copied to computer and back to car in one go, or i forget it. With multiple cards i should have one in camera every time i drive, but it totally wastes wifi-functionality. Copying cards to pc is 30-40 times faster though.. In reality even more, if i need to transfer files from phone to computer.
'* I mentioned slow or failed loading of map in earlier message, that was for the map you see while trying to watch the video in portrait mode. Maps showed beside video thumbnails in clip selector do show up, even if i cant watch the videos.
