Samsung Galaxy S10 may come in three sizes, with in-display fingerprint sensor, says analyst Ming-Chi KuoJuly 17 (AZINS) Samsung's next flagship smartphone, due early in 2019, could be coming in three separate versions in a bid to broaden its appeal, according to TF International Securities analyst Ming-Chi Kuo.

According to a report by Business Insider, the Galaxy S10 will be offered in three variants - 5.8-inch screen, 6.1-inch screen and 6.4-inch screen. The two larger models will include an ultrasonic FOD - ‘fingerprint on display,’ which implies that users will be able to scan their finger by placing it simply on the screen. The smallest model will include a fingerprint scanner towards the side of the device. The company will ‘aggressively’ promote this new feature and it is also expected to be used on Samsung's high-end "A series" devices as well.

Ming-Chi Kuo predicts Samsung to ship 40 million Galaxy S10 devices next year. Also he believes that Samsung could ship 14 million to 16 million Galaxy Note 10 phones next year as well.

Previous reports suggest that the 5.8-inch smartphone will sport a single main camera. The second model, with curved edges and a dual camera, would effectively be a replacement for the Galaxy S9, while a more advanced model, will sport a triple camera, and would replace the Galaxy S9+. If this materializes, Samsung would be a major challenger for Huawei in the smartphone camera field, in which both manufacturers strive to excel.

A fingerprint sensor built into the screen -- technology already mastered by many Chinese manufacturers like Huawei, Vivo and Xiaomi -- should at least be coming to the higher-end Galaxy S10. Plus, Samsung could add facial-recognition technology, similar to that seen in Apple's iPhone X, thus ditching its iris scanner.

This would take the form of a 3D module built into the front-facing camera, bringing improved facial recognition while also optimizing animated emojis. The Galaxy S10 is also expected to be the first smartphone to use the next-generation Qualcomm Snapdragon 855 processor. The Galaxy S10 smartphones are likely to be unveiled at CES 2019 in Las Vegas, January 8-11, 2019.
