On the 20 17 MWC, vivoX20plus attracted much attention because of fingerprint unlocking, and at that time, the mobile phone was also equipped with a unique dual fingerprint identification system, which made it more convenient and faster to unlock the mobile phone. Vivo is still trying to unlock the screen fingerprint. In 20 18, the new mobile phone x2 1 series of covivo was released, which showed the new achievements of vivo in unlocking off-screen fingerprints, and the recognition speed and accuracy were greatly improved compared with the previous generation.
In 20 19, vivo released a brand-new nex series, and at the same time, the fingerprint unlocking of vivo was updated to the latest generation: the third generation, this nex series, can even unlock the fingerprint of the screen when the finger is wet. The fingerprint unlocking technology of vivo has become more and more mature, and with the development of fingerprint unlocking of vivo, the screen ratio of vivo mobile phones is also increasing, so it is no longer necessary to leave fingerprint buttons like other mobile phones.
Through the development of vivo fingerprint unlocking technology in recent years, we must admit that in the current domestic mobile phone operators, the screen fingerprint unlocking of vivo is the most mature and perfect, and before 19, the screen fingerprint unlocking needs to use vivo. Until last year, other mobile phone operators developed off-screen fingerprint unlocking technology, but their fingerprint unlocking technology was not as good as vivo. At present, vivo has been used in fingerprint unlocking in China.
