Great app!
N97 firmware: 12.0.024
did a half-reset (*#7370#), a hard-reset (SHIFT+SPACE+BACKSPACE while powering up) and formated mass storage so everything is clean
The magnificer is sometimes upside down. If i move it to the upper left corner of the image, it moves to the lower right and vice-versa. This happens if i've rotated the image on the phone AND if i've moved photos from my C902 (has accel-sensor too) to my N97.
Guess you have to tell the magnificer to ignore the EXIF-information and use the current information (use the accel-sensor in the N97 to decide if portait or landscape and then check where the user is touching the display).
Please push this app forward, the default photo viewer on the N97 is extremly buggy (crashes all apps if you zoom into too high and often doesn't sharpen zoomed images).
Later i'll publish a photo with which this bug happens, so you can test yourself. Wait for my reply on this.
