But things don't have to be this way.
Qualcomm says its technology will be the first of such that's commercially available, capable of scanning through either OLED displays or aluminum, and that the company is planning to make its Fingerprint Sensors available to OEMs as early as this month - which means we should expect to see the technology debut in high-end smartphones as early as the first-half of 2018.
"We are excited to announce Qualcomm Fingerprint Sensors because they can be created to support sleeker, cutting-edge form factors, unique mobile authentication experiences, and enhanced security authentication", said Seshu Madhavapeddy, Qualcomm Technologies's vice president of product management. We are really impressed by Vivo and wish the company keeps bring new technology for all technology enthusiasts to enjoy.More news: Curry, James lead fan voting for All-Star game

Recently, Synaptics released new in-display fingerprint sensing solutions for AMOLED panels. Vivo In-Display Fingerprint Scanning Technology replaces the physical fingerprint button on the screen, laying the foundation for a truly immersive experience. For one, people screw up their screens all the time.
A fingerprint icon on the lockscreen shows you where to place your finger. However, the sensor wasn't as responsive as Vivo would have liked. The fingerprint reader itself is about the size of a small coin and works by scanning your finger through the tiny gaps found along the phone's pixels. But sadly none of the big smartphone manufacturers were able to implement this feature in their flagship phones. You can find out more details about this new technology over at Vivo at the link below. But if you tilt the phone up to activate the "lift to wake" mode, the OLED screen shows an always-on clock and gives you a nice little animation when you press into it.
Using it was as natural as you't want it to be: I just held my finger over a lit-up area on the Vivo phone's screen, and it unlocked quickly and consistently. If you're just slightly off, it usually fails to recognize it. The chip-maker went on to explain that the sensors were developed as an "integrated solution" that would work in tandem with the chip-maker's expansive line of Snapdragon CPUs for mobile devices. We played with Samsung's Iris scanner too, that works quite good but it gets confused by a bright sun.
