SolGrader works with a synchronization process between the app and the data portal. SolGrader can work without internet connection. The synchronization button will become orange in the right top of the screen. If you have internet connection again, push the button and the data will be synchronized, meaning also stored in the data portal. When it is not working press the button once more.

In case of an unexpected error the button can stay orange meaning that the data is not stored in the data portal. In case of that an hard removal of this data on the app can be accomplished in the More screen. In case of a synchronization error an option will appear to do a “hard” removal of the data. This should only be used as a last resort.

Try to follow the tips below:

– hold your phone as steady as possible,
– align the white corners with blue mat corners and a cross with a red square,
– keep the red square visible and 2 cm free space from its edges,
– potatoes should not be too close or on the edges of the blue mat,
– potatoes should not be “touching” each other,
– keep the blue mat relatively clean,
  When there are other objects on the blue mat like dirt,
  small branches, they may be detected and measured as well,
– place a smaller amount of potatoes on the blue mat,
– avoid placing the mat directly in the sun, as strong shadows will affect the measurement.

This issue can appear due to a few reasons:

1. Check if your phone is compatible with the app – List of supported phones.

2. Make sure you align the white corners with blue mat corners and a white cross with a red square

3. Hold your phone as steady as possible, while taking the photo.
