Unfortunately, the app is not yet really mature. On my Sony Xperia function photos well. That the transitions and effects are not working in a PowerPoint presentation is still unacceptable that individual slides are displayed in an unexpected but font color, font size and overwritten with letters (despite standard fonts), this feature makes it unusable. Only PDF is displayed correctly. If you make a presentation, you must not wait too long to the next slide, because after a long time, freezes and apparently also the hardware the app. Turning then the Tab from the last image remains still stand on the screen and is moving even by restarting the app on Tab to no response. Only the mains plug on EZCast solves this problem.
