OnePlus 5 is currently out of stock in the UK and US.
In the UK, the hugely-popular flagship smartphone is no longer available in a Slate Grey finish – in either 64GB or 128GB storage configurations.
Mobile network O2, which is the exclusive carrier for the OnePlus 5 in the UK, still has some stock available.
So, it is still possible to buy the handset in the UK, but you’ll be tied to a contract.
Meanwhile, all three variations of the phone are currently out of stock in the OnePlus online store in the United States.
This stock shortage has triggered a flurry of speculation amongst fans that OnePlus is preparing to launch a new model.
After all, the Chinese smartphone start-up unveiled a minor upgrade to its 2016 flagship smartphone some six months after it first launched.
If OnePlus decides to follow the same pattern, an incremental upgrade would be due in the next month or so.
However, it’s unlikely the current stock shortages are because of an upcoming OnePlus 5T announcement, or OnePlus 6 for that matter.
This time last year, there were already a swathe of rumours about a new OnePlus handset.
Coupled with that, Qualcomm had launched a new flagship chipset, the SnapDragon 821, which offered significantly more power than the Snapdragon 820 used in the OnePlus 3.
Qualcomm has only launched one top-of-the-line processor this year, the SnapDragon 835, which is inside the OnePlus 5.
Best guess – the stock shortages are probably due to supply issues at OnePlus.
OnePlus has struggled to keep up with demand in the past, so it’s nothing unusual.
Plus, the Chinese company recently offered a number of promotions for students, which might have triggered a surge in demand the company could not meet.
Express.co.uk has approached OnePlus for comment on this story.
We’ll update the article as soon as we hear back.
