Hi guys Im a total newbie to tablets so im looking for some help with regards the settings of the night mode in ezpdf. When i boutght the tablet ezpdf was pre loaded and had a fantastic night mode which turned the background black and the text white. However after a few daays i decided to start playing with the settings... bad move! There is a colour wheel to change the text and another to change the background which i swirled only to discover that there is no black and no white on these wheels so i cannot return it to its original (brill) format. I downloaded the user guide - useless, searched high and low -nothing, and tried to find a factory reset, no such luck! Does anyone know how to do this? Any help greatly appreciated!
