We noticed that Samsung likes to release speculations here and there shortly before Samsung's announcement Galaxy Tab S. But the company has recently fueled speculation about Galaxy Note 4 and eye scanning capabilities. According to several speculations, the phone should contain a corneal sensor, which should represent an even higher level of security than that provided by the fingerprint sensor.
But it is necessary to point out the fact that the fingerprint sensor on Samsung Galaxy S5 is not exactly the most perfect and as I already noted in our Samsung review Galaxy S5, I personally only used the fingerprint sensor for a few minutes before turning it off again. In the event that Samsung goes further and decides to Galaxy Note 4 to use a corneal sensor, it could mean that the phone will include a better quality front camera with an even higher resolution than before. Galaxy The Note 3 has a 2-megapixel camera, but it is possible that the Note 4 will already offer a 5-megapixel camera and a sensor that will be able to emit weak infrared light. Of course, it should be taken into account that this is only speculation for now, but in the image released by Samsung, we see an eye on the phone's screen and a description "Unlock the Future", which can lead to long-term speculation.
