One of the best things about the HTC One A9 is the fingerprint sensor. The sensor is fast and reliable, just like a fingerprint sensor needs to be. If it�s not fast and reliable, you�re not going to want to use it. Samsung�s fingerprint sensor on the latest Galaxy phones was starting to feel like more of a nuisance to me. I decided to compare the sensors to see if HTC�s truly is much better.
As you can see in the video, the results were not nearly as one-sided as I thought. The Samsung Galaxy S6 Edge Plus proved to be relatively fast and surprisingly accurate. The One A9 also performed well, but I was expecting that. When the One A9 failed I was able to get it right on the next try or third try, but when Samsung�s failed I couldn�t seem to get it right.
The speed of the two sensors was also closer than I anticipated. When both displays are turned on, it�s a very tight race, but HTC�s sensor is much faster when the display is turned off. However, I think that is more a fault of the software than the sensor. The Edge+ seemed to hang just a bit longer on the lock screen. There�s one thing that makes all of these results so impressive: processors.
The Edge+ is running with Samsung�s beefy Exynos 7420, while the One A9 is running a much weaker Snapdragon 617. It was still able to keep up. I can�t help but imagine how insanely fast the HTC sensor would be if it had an equal processor. Kudos to HTC for doing a great job. Hopefully, they will be able to replicate this experience on their next flagship phone. I�m not sure I can go back to a phone without one.
