While my new external USB hard drive came with a 50 pages manual, of which none were useful, my android smatphone came without manual. HHopefully it's just because I bought it in a small shop in Taiwan... but still it seems most android apps are poorly documented.
After a difficult (early) morning, I discover that there was a screen capture folder with a screenshot in it. It turns out that Samsung has added to the galaxy ace a shortcut to screen capture: back + home (you actually have to press in this order). Surprisingly, on other phones, it's a different combination... as if it was still too easy to find ;-)
I also recently realised that long pressing a key can bring a special action. For instance in the mail client and browser, pressing long menu brings the search widget. Long pressing back in the browser brings the history.
There is also this horrible design which makes the camera application to lock/unlock the interface if power is pressed. Not stupid but completely unstandard. I rebooted my phone twice because I thought the camera had gone blocked before realizing this.
So far I haven't any action activated by the accelerometer, like undo on the iPhone. Still, the picture gallery react a bit to it by tilting the images, so there is hope to find such a hidden unpractical feature...
Any one knows some other shortcuts? Maybe I should start reading the source code to replace the user manual?
