Samsung has begun sending out invitations to the launch of its first flagship phone of 2019.

The event will take place at San Francisco’s Bill Graham Civic Auditorium at 11 am PST for the 10th anniversary of the Galaxy series.

It’s rumored Samsung’s “fully functional” foldable phone will finally debut alongside three different Galaxy S10 models that sport an Infinity-O display. The three models have been dubbed the S10, S10 Plus, and S10 E, similar to the latest naming scheme of Apple’s iPhone XS. A fourth-model with 5G capabilities and improved specs is expected to be announced at the Mobile World Congress in Barcelona.
