I am new to android devices and struggling with reading pdfs. I have a white 7" Pandigital with SH20_20110127_K_PD_INX7E_ENG_6410POP (2011 series) Vanilla Android homescreen. I have copied some pdfs onto the device and the B&N app will open them but the text is way too small and there doesn't seem to be any way to zoom in. I tried converting them to epubs, same problem. I assume it's because the files contain images and not text and are displayed as a full page fitted to the screen size. I downloaded and installed the Adobe pdf reader which is supposed to zoom, pan etc. but it does not see any of the pdf files. Is there a good solution to this? How do I get to read my pdf files enlarged sufficiently so I can actually read them? I have some grasp of how files a found in windows, is there an explanation someplace for this os? Thanks for any help, John.
