The pictures of Samsung's new Galaxy smartphone, which is expected to be released in New York this week, have been leaked online, a report has said.
A series of images published on a Chinese forum for Samsung fans showed a smartphone that users claim is the new Galaxy S4.
The handset appears slightly larger than the S3, the Telegraph reports.
According to the Verge, which picked up the photos, the forum claimed the phone has a 1080p display, runs Android 4.2.1, has a 1.8GHz Universal5410 processor and 2GB of RAM.
The authenticity of the images is uncertain but they do not match pictures published by SamMobile in January, which showed a similar device but without a button on the front, the paper said.
SamMobile reported that the Galaxy S4 would feature a "floating touch" display, which would allow people to control the phone without touching the screen.
