Unstable Crashed within minutes of first use. Tablet's Screen brightness is overridden by the app. The app increases brightness to maximum for day and night reading. So  this will drain battery life rapidly  and reading at night will ruin my eyes. It looks like a good app otherwise  except for these very fatal flaws. Why doesn't android have a good stable eBook reader that does a good job with PDFs ?? I have tried a half dozen apps  and all at any price  have fatal flaws that render reading PDFs painful  unreliable.
