(Pocket-lint) - The Samsung Galaxy S10 phone range must be the company's worst kept secret ever. We've seen pictures, logos, pictures of logos, hands-on videos, hands-off videos and even Samsung got in on the act itself, pasting a massive "10" on its Galaxy Unpacked event invite.

However, few of the leaks have been so accidentally disastrous as the screening of the full, official Samsung Galaxy S10+ commercial in Norway - two days before the handset is to be revealed.

A Samsung exec might as well take stage on Wednesday, go "here's the thing you already know everything about" and walk straight off, pointing press to a hands-on area as they leave. Would certainly make the livestream a lot shorter.

You can watch the advert above. It was filmed playing on his TV by Endre Loeset and posted on YouTube.

It also shows the Galaxy Buds wireless earphones and the reverse charging feature, whereby you can place their charging case on the rear of the phone and charge them through mere contact.

To be fair, there are few surprises. The triple-camera system on the rear has been rumoured and leaked many times. We can also see that the display seems to have HDR style contrast and colour representation.

We even get to see the S10 and S10+ together at the end.

No matter how much you already know about the phones though, we still urge you to join us tomorrow for the live Galaxy Unpacked show. There will be other devices on display too, so plenty still to get excited about.
