In January, the CEO of Huawei's consumer business, Richard Yu, said the company plans to snatch Samsung's coveted title as world's largest smartphone brand by the end of 2020, or "this year at the soonest."
Keep in mind that while the entire Galaxy S10 family has been tested and reviewed (including the S10 Plus and Galaxy S10E), we've only had limited time with the P30 Pro, so we'll be limited to educated guesswork until we can truly compare the two side by side.
In addition to the P30 Pro, Huawei also introduced the Huawei P30, which is a little smaller and has fewer frills.
If you're one who would, then Samsung has the advantage here, in theory at least.
Qualcomm says that method is slower and less secure, but I haven't had a lot of luck accurately unlocking the S10 or S10 Plus on the first try.
That said, other optical in-screen fingerprint scanners have also been touch and go, so it's uncertain if the P30 Pro's technique is faster.
