I have Samsung Galaxy Tab S tablet.
I want to use it for reading documents, in particular PDF and Word files.
The problem is, even after adjusting/reducing the screen brightness, it is a tiring reading experience.
Is it possible to use Sepia as background colour either on the tablet screen or the document?
I am told that Sepia is much more reader friendly display.
I will also welcome any other ideas you may have.
The only suggestion I have is the Kindle app allows sepia as a background colour and works on PDF files. I doubt you will be able to do anything about Word files although use the Blue Light filter if your tablet has one.
