Samsung Electronics is set to unveil the Galaxy S4 smartphone at a March 15 event, according to fan site SamMobile.
The successor to Samsung's Galaxy S flagship franchise will begin selling in early April, according to the report, which cited an unnamed source.
Samsung, meanwhile, remained mum on the timing of the launch.
"We don't comment on rumors or speculation," said a Samsung representative.
There's increasing interest in the launch of the next Galaxy S smartphone, which Samsung has built up as a worthy rival to Apple's iPhone franchise. The Galaxy S3 landed with all of the attention of an Apple launch, and the anticipation over the Galaxy S4 is expected to be even higher.
The fan site's report has the invitations coming out after Mobile World Congress, which kicks off in the last week of February.
As with previous launches, the Galaxy S4 would launch in Europe and Asia before the end of April, the fan site said, while the Americas, Australia, and Africa will get the phone around May or June. The Galaxy S3 launched in the U.S. months after its debut, partly due to carrier testing and scheduling needs.
