Dreamy Galaxy S10 concept render

The sluggish rollout of 5G service around the world is making life unusually difficult for Samsung and Apple, which may need to reconsider their traditional flagship smartphone release models.

This unnamed device (cough, Galaxy S10, cough) will be brought to market “in the first half of 2019”, most likely after that special 5G Moto Mod allowing owners of the Verizon-exclusive Moto Z3 to upgrade to the new cellular standard.
T-Mobile and AT&T have made their own strides towards (eventually) leaving 4G LTE behind, so at least theoretically, a 5G-capable Galaxy S10 could be released on all the big four US networks during the first half of next year.
In the meantime, Verizon and Samsung are preparing a proof of concept showcase for the Qualcomm Snapdragon Technology Summit in Maui this week, where the Snapdragon 855 processor will finally be detailed.
That obviously means the 5G Samsung phone slated for a Verizon debut in early 2019 will be powered by this “upcoming flagship Qualcomm Snapdragon Mobile Platform” and a Snapdragon X50 modem.
