And if you don’t notice at the right time, you have to do reset

It lost the time twice

The iOS app did crash a couple times, but was able to complete what I was doing once it restarted.

You can also do time-lapse video.--Camera itself feel very good quality

Pros:1- Very Nice video quality, the 4k is clear and the size of the video is small corresponding to the length time of the video.2- Time Lapse feature is great and has different option to make it running fast or slow (4 image per second is the fastest and 1 image per 2 second is the slower)3- You can take picture while it's recording video

The seller got back to me in good time

Junk junk big time

But it froze 4 times in the 7 days of driving

One little annoyance is that time-lapse mode doesn't persist, so you have to keep changing to time-lapse mode every time you get in your car, if you want to use that.
