Version 3.8
For Android Mobile and Tablet
This app records your journey in multiple video files format mp4. These files integrate GPS location data, which are stored in SQL database. GPS data is used when replaying video or when reviewing the route on MAP.
This app can capture normal photo, captures photo while recording (Android OS 4.3 and newer), automatically takes photo when you suddenly speed UP/DOWN with acceleration over the prior setting threshold (Android OS 4.3 and newer).
When reviewing video you can retrieve any frame of it by taking Snapshot.
All photos taken by this app contain Exif information (GPS data) if GPS is available. Exif data is used for locating photo on Google map later.
This app uses the way of looped recording on multiple video files. (for saving the space of device's storage)
This DEMO version only allows looped recording on a queue of 2 video files with duration of a minute per file
The number of photos captured by this DEMO version is limited to 20 photos
Layouts:
This Application supports two screen orientation layouts - Landscape and Portrait.
Automatically locks the current orientation when starting the recording process. So it is very convenient for making videos either in landscape or in portrait layout without change the settings.

Acceleration calculation
Use GPS speed to calculate acceleration
a = changes of speed per second (m/s²)
Settings: easily and simply
1. Measure unit of velocity: Km/h or MPH
2. Allowing audio recording or not
3. Acceleration threshold: 2.5 m/s² or 3.0 m/s² or 3.5 m/s²
Deleting Files:
The GPS data are attached at the video file if GPS device is turned ON and active. So You must delete video files by using rightly the context menu of Dashcam Pro/DEMO, else you will leave GPS Data part without deleted from the database. (if you use Gallery to remove files, it can not remove GPS data part attached and if it happened the only way of repair is the uninstalling app and reinstalling it

Videos (images) either have gps data or not, that depends on if the built-in gps devive is ON or OFF. So videos (images) will playback with or without gps data
