Apparently, a picture of the Samsung Galaxy S4 remained online on Picasa for almost a month without anyone noticing it.
Desmond Ma, a student from Hong Kong, uploaded a picture to Picasa almost a month ago.
With a shape reminiscent of the Galaxy S3, the device appears to have sharper corners, while the Home button is physical and seems to be larger.
The size increases for the new model, even if the frame at the sides is reduced by a few millimeters.
Samsung is rumored to announce the device at a press conference on March 22.
