Changing the battery helped. Now the indicator goes to last line and then it shuts down
With the current update we have got very powerful reading device thanks to all the members of this forum, especially to Booxtor. To make it even better my humble request is to make sure that when battery are low and then the device is just about to shut down, to save and close the file being worked on together with the scribbles and annotations. It does not happen as yet. Another would be to make a save button and/or to make sure that with flipping every page the scribbles get saved.
