We didn't know much about the Lenovo K4 Note until the Chinese company released a few teasers last week. After letting customers in India know about its plans to launch a “Killer Note,” Lenovo confirmed. the K4 Note would pack 3GB RAM. This week, Lenovo releases a few more teasers that hint at some of the hardware the smartphone will pack inside. For example, the Chinese company has confirmed that Lenovo K4 Note comes with both fingerprint sensor and NFC (Near Field Communication) support. Aside from that, Lenovo hinted at a possible Quad HD display, though we can't say for sure that this is what the Chinese handset maker wants to say.
