On the photos we see three types of fingerprint scanners. The square one is a typical rear-housed scanner like that employed on Huawei Mate 7. It has a matte face like the second one. The third, with a smooth mirroring touch tablet, is what stars in Ulefone Be Touch as well as its successor Ulefone Be Touch 2. Well, the three pictures reveal a story about how Ulefone once struggled over this part of its industrial design.
In fact, the company took rear fingerprint scanner into consideration at the first place, because such a plan is easy to carry out. If you have watched the Be Touch teardown video, you will see the upper body of the phone has richer space. For example you may leave a hole on the inner back shell to bear the scanner, which is not thicker. However, some considerations impelled Ulefone to give up the easier plan:
1, it’s obvious that a new feature is always more natural to a man when it is borne by something and realized by some action you are familiar with, such as the home button, such as a press on it. 2, adjustment of grip would be quite frequent as your finger was going to reach a small place by a proper manner on a phablet as big as Ulefone Be Touch, while you always know where your home button is. 3, the index fingerprint may serve as your only convenient identification as for a rear scanner even if you can register five. But on the face of phone, you can use any finger which make you feel natural. 4, When you are working or talking with somebody, you often only want to glance at your phone on the desk when some notifications come. With rear fingerprint scanner, you have to pick your phone up first.
Finally, Ulefone decided to place the sensor below the screen, even if this scheme involved more sweat and tears over space arrangement and circuit design. Then comes another question, what type of element should be employed. At that time, there were two options, wafer with plastic package, or with ceramics panel. The first one cost less, which is a big tempt for a company making budget phones, but has a rough surface. And the ceramics panel better fits the 2.5D glass visually and is more responsive. I don’t know how the bosses in the company conflicted and compromised over this issue, but they picked a user-friendly solution in the end. And luckily, consumers vote for their decision with money.
Sor far we see in the market so many mobile phone brands have released their fingerprint ID products since Apple started hyping the concept 2 years ago. But it seems most phones with such a feature are way too far from what people are longing for, namely, fingerprint payment. Fingerprint ID on phones other than iPhone just function as a method of unlocking, faster than passwords and patterns, safer than swiping, and more accurate than voice. In this sense, front fingerprint scanner better realizes the concept of shortcut.
