Samsung Galaxy S10

Samsung is planning to release three models of the

Samsung Galaxy S10, its flagship phone, in 2019,

according to a new report from the TF International

Securities analyst Ming-Chi Kuo.

He believes the S10 lineup, usually launched in the spring,

will come with three models: one with a 5.8-inch screen,

one with a 6.1-inch screen, and one with a 6.4-inch screen.

One key feature Samsung will promote next year is a

"fingerprint on display," or "FOD," reader, meaning users

will be able to scan their finger by placing it on the screen.

According to the Sunday report seen by Business Insider,

the two larger, higher-end Galaxy S10 models will have the

"ultrasonic FOD" feature, while the smaller Galaxy S10 will

have the fingerprint sensor on the side of the device.

The Galaxy S9 has a fingerprint reader on the back. Apple

has opted to remove the fingerprint reader from its iPhones

— this year it's expected to release three new iPhones, each

without a fingerprint sensor. And people with the iPhone X

instead use Apple's proprietary Face ID camera to unlock

their phone.

Kuo said he believes Samsung will "aggressively" promote

the on-screen fingerprint scanning — after all, it's one feature

Apple's not planning to match. The fingerprint-on-display part

is expected to be used on Samsung's high-end "A series"

phones and the Note 10, which will probably launch in fall

2019 and could have a 3D-sensing camera as well. The

ultrasonic FOD part is made by GIS and O-film and based

on a Qualcomm design and software, according to the report.

Kuo predicts Samsung could ship 40 million Galaxy S10

phones next year — mostly the two larger models, which will

be more expensive. Samsung could also ship 14 million to 16

million Galaxy Note 10 phones next year, according to the TF

International Securities forecast.

Kuo's research is geared toward investors in Asian parts

suppliers, and in the note he picked several potential winners

if ultrasonic fingerprint scanning becomes widespread. He has

a reputation for correctly forecasting technical details for

upcoming phones and laptops, particularly those from Apple.
