i don't know if its for all phones but on my htc desire hd there is single line of pixels at top of screen in landscape view that has a very small dark tint to it. its hard to notice but its there, first i thought it was my screen but i switched to portrait view and the problem goes away.
i hope someone can confirm this also checked out other comic readers like comic reader mobi and perfect viewer they don't have the same problem but i don't like the others, perfect viewer still has a lot of work to be done on it and comic reader mobi is good but it has no pinch to zoom and its slower. the only issues with droid comic viewer is that scrolling is jerky and page transition is not very responsive. also u should get rid of the single tap zoom as default as lots of times i kept zooming in when i did not want too, of course when i found out i could turn it off and have double tap as zoom in the settings it was fine. thanks for this great app and i hope you can fix this bug and improve scrolling.
