Chinese tech company Oppo has lifted the lid on its first teaser-trailer for the Oppo N1 flagship smartphone, due to be revealed in full on 23 September.

The company, well known for its Blu-ray and upscaling DVD players, is fairly new to the smartphone market. Following on from the release of the Find 5 to western countries earlier in 2013, the N1 teaser seems to suggest the flagship handset will be all about its camera functionality.

How so? The rather bizarre trailer shows us glimpses of an ISO 12233 standard chart - used to measure resolution - scattered among close-ups of a colour chart. All very technical.

What the trailer doesn't show is the smartphone itself. Not even a glimpse. D'oh. All we know is that it will be called the N1 - the official title, webpage and hashtag are more than a giveaway there.

There's more to come, too. A countdown timer on the official Oppo site will reveal a new trailer every three days.

But for full-on coverage Pocket-lint will be in Beijing for the launch of the Oppo N1 on 23 September. We'll be sure to bring you the lowdown on this latest flagship. In such a busy market full of various company ups and downs can Oppo break through with this release; will it be a case of move over Samsung? We'll just have to wait and see.
