Fingerprint sensor is the latest frontier for smartphone companies.

Since the introduction of the iPhone 5S and the fingerprint sensor, companies are trying to find a way to improve the sensor’s reliability, response time and placement. It took the Android phones more than a year to adjust to the new market, but it seems like Samsung finally has a worthy competitor with the Galaxy S6. So, which fingerprint sensor is better: the one in the iPhone 6 or the one in the Samsung Galaxy S6? Let’s compare.


Before we look into other features and advantages, we must look at the placement of the sensor. In this case, both sensors are placed on the home button. Samsung failed miserably with the fingerprint sensor of the Note 4, which required a swipe to work. Now, the company has placed the sensor on the home button. The button doubles as a sensor and a designated button as well.

Galaxy S6 advantages

The fingerprint sensors of the iPhone 6 and the S6 are very close in response time, features and accessibility. There is one small advantage that Samsung has over Apple. In this case, that is the option to use the fingerprint sensor for signing into web accounts. Neither flagship can wake up the phone with a fingerprint scan or lock an application. Both can be used for mobile payments, but the S6 can also use the fingerprint sensor for web accounts. It is a small advantage, but it is still an advantage.

Response time

The response time is measured from the moment you pick up the phone. Both the S6 and the iPhone 6 need to wake up the screen before they can use the fingerprint sensor. The good news is that the home button can be used for both functions. In our test, the Samsung Galaxy S6 needed 1.2 seconds to perform a successful scan, while the iPhone 6 needed 1.4 seconds.

Success Rate

One aspect that is underrated with the fingerprint sensor is the success rate. The success rate is one of the reasons the Galaxy Note 4 was not praised for its fingerprint sensor. The Note 4 had a success rate of around 70-80%, and was hard to use due to the swipe, slow response time and comfort. On the other hand, the Galaxy S6 has a success rate of 100%. We tried it 100 times, and it never failed. The iPhone 6 is close, but out of 100 times, it failed to perform a successful scan three times.
