As the Oppo N3’s launch draws nearer, the countdown to the Chinese smartphone maker’s latest flagship can be tracked on one hand. October 29th is the date when Oppo will reveal what it’s been hiding behind the curtain and what the N3 really brings to the table.But it’s not just the N3, Oppo has another surprise in store as it showed in the image it released earlier today as a teaser for the N3. While the N3 takes one half of the big curtain, another Oppo device can be seen hiding behind the other drape.This image, released on Chinese social network Weibo shows the second device which is very similar to the earliest leaked renders of the Oppo N3 itself. Going by those images, this device -which is a sudden entry and has no word on it from Oppo anyway- could feature a rotating camera as well but as far as the specs go, no details there.While we’re talking of the Oppo N3, this smartphone is expected to run a new cooling system designed by Oppo and will be housed in lithium-aluminium casing. The Oppo N3 is expected to sport a 16MP rotary camera with a 1/2.3 inch sensor. This device is said to run a Snapdragon 805 Soc and had a Quad HD display.The other mystery device could then be a mid-range alternative to the N3 and perhaps go under the moniker Oppo N2.
