Back in 2017, Apple made a bold move by removing touch ID from its phones and replacing it with Face ID which had all the fancy tech for 3D face scanning and that divided opinion. Some preffered the quicker response time of the fingerprint sensor, while others preffered not having to use a finger to open the phone which unlocks itself just by looking at you. However, like all other Apple tech introduced previously, people got used to it and it became very popular. Popular to such an extent that people stopped desiring the Touch ID.
According to renowned Apple analyst Ming-Chi Kuo, Apple might just be waiting for under-display fingerprint technology to get mature enough so that they could use it in their own phones.

Ever since the popularity of maximizing screen to body ratio, companies have tried various methods to get the fingerprint somewhere near the natural holding position of the user. The best innovation in this has been the under display fingerprint sensor. However, it is still in its early stages and there still are speed issues. Now that Apple has mended the relationship with Qualcomm, it could be using the Qualcomm’s ultrasonic fingerprint technology when the time is right.
However, there are still things that Apple would have to keep under mind before a technology of that sort gets added to their phones. Power consumption, size of the sensing area, thickness of the module and the production yield rate are all things that are very important when it comes to coming up with an under display fingerprint sensor which is as efficient as the proper sensors.
All of this is still analysis of what Apple has been doing for the past few years and that is waiting for technologies to get mature enough to be used in their phones.
