Mobile World Congress returned in full force with the most interesting mobile innovations we've seen in years.

Foldable phones and 5G stole the show in Barcelona. It was all but impossible to escape these two big trends at the year's largest mobile event.

As expected, Samsung and Huawei dominated MWC with phones like the Galaxy S10 and foldable Mate X. No surprise, considering these tech titans are also the two largest phone makers in the world. We were also treated to a few surprises like Microsoft's HoloLens 2.

After years of the same old, mobile is exciting once again.

Without further ado, here's Mashable's top picks of MWC 2019. As always, we'll continue to update the list throughout the show, so be sure to check back for new additions.
