Owners of OnePlus smartphones have been warned that their private photos and location could be exposed.

The gadgets come with an app that could be easily manipulated by jealous partners, hackers or crooks looking to blackmail its owner.

The OnePlusLogKit is a debugging app that is used to constantly improve the software on a phone once it has left the factory.

But one hacker has spotted that it is easily hacked and could put OnePlus owners at risk of an indecent exposure.

Known only as Elliot Alderson — the main character in USA Network’s hit hacking drama “Mr. Robot” — the security expert warned that anyone could access a phone owner’s GPS location and Wi-Fi connections along with photos or saved files.

That means that if you’ve taken any Kim Kardashian-style nude photos, they could be up for grabs.

All a hacker would need is access to a handset just once, to dial a number and click a button.

This is the second app that was found on phones delivered straight to customers.

Earlier this week, Alderson found an app named EngineerMode that allowed someone to take total control of the phone’s operating system but hid any trace of it being there.

OnePlus said in a statement that it would remove the app in the next operating system update but did not appear concerned that it was a major security problem.

It said: “While we don’t see this as a major security issue, we understand that users may still have concerns and therefore we will remove the adb root function from EngineerMode in an upcoming OTA.”

There’s no word yet from OnePlus regarding the latest logging app, but the Sun Online has contacted them for comment.

The outsider phone company has got a cult following thanks to its great value and clean design.

An invite-only launch in 2014 meant customers would have had to win competitions or a get a friend’s referral to get their hands on a gadget that promised the same features as the latest expensive smartphones — at almost half the cost.
