Pre-orders for the Galaxy Note 7 are just going live in Europe this week, but already Samsung has issued a warning that it will have to cap Note 7 stock allocated for pre-orders on the continent. The company cited “unprecedented” demand for its new smartphone as the reason, but hasn’t given out any details about how long the situation could last.

The news arrives just one week after the Galaxy Note 7’s launch was delayed in Malaysia, the Netherlands, Russia, and Ukraine. Again, the company produced unexpectedly high demand as the cause. According to figures from Canada and South Korea, Note 7 pre-orders have doubled those made for the Galaxy S7 and S7 edge combined, potentially making it Samsung’s most popular flagship launch to date.

“Market reaction, combined with extremely positive feedback from our carrier and retail partners, indicates that the Note 7 will exceed our original sales forecasts for the region by some distance … As such, the number of preorder units will be limited due to the unprecedented demand.” – Conor Pierce, Samsung’s vice president of IT and mobile for UK and Ireland

The stock situation already appears to be having an effect on pre-orders. Samsung now lists the Galaxy Note 7 as “Out of stock” on its UK website, although the phone can still be picked up through carrier websites. Fortunately, pre-orders are still available direct from Samsung in Germany, France, and Spain, at the time of writing.

Galaxy Note 7 stock is still scheduled to ship to European customers on September 2nd, however some consumers might now be facing delays until Samsung can improve its supply situation. If you’re still on the fence about pre-ordering a Note 7 and live in Europe, you’ll want to make a decision as soon as possible.
