V3 SD Card Playback is skipping playing the first minute of every hour.
@WyzeBaohua @WyzeDesmond I can confirm the issue @SirDom reported above with this same firmware, but I tested it while using the Android app Ver: 2.35.0.b80
I went back to see if I could find a pattern, and interestingly enough for me, the playback is skipping the FIRST minute of every hour just like it did in SirDom’s video above. I can go to any hour on the SD card, scroll to just before it switches to the new hour (example: 9:59:55pm) and tell it to play, and within 1 second of the new hour updating, the playback will skip an entire minute. So in SirDom’s example above you see it skip from 10:00:00 straight to 10:01:01. It is doing this for every single hour on every V3 I’ve tested so far 100% of the time. I am guessing it is happening to every V3 and skipping the first minute of playback of the new hour for everyone on this firmware.
To add to this, just as in SirDom’s issue, I can confirm that the video is actually there. If I scroll to 10:00:01 or later then it will actually play the entire minute that it otherwise skips over.
So far all of my tests on multiple V3’s for multiple times have had this happen 100% of the time, so I’m sure it will be easy for you to reproduce. I’m guessing it is a firmware bug (it is occurring on multiple app versions including on both iOS and Android).
