Have you enabled all of these features?

  • Samsung will launch a publicity to raise awareness of crucial security features
  • Campaign was created with UK Home Office
  • It's all part of a renewed push to prevent mobile phone thefts
  • London outstrips its European counterparts when it comes to phone theft
  • One smartphone is stolen in the UK capital every 7.5 minutes

Samsung doesn't think you're making the most of the security features baked into its devices.

The South Korean firm has launched a publicity campaign to ensure that millions of Galaxy device owners in the UK are taking advantage of its robust privacy and security features. Samsung says it will reach more than 40 million smartphone users by issuing alerts via its Samsung Members platform and social media channels.


It's also planning marketing campaigns at Piccadilly Lights, advertisements in railway stations and the London Underground network. Television adverts are also in the works to bolster awareness, Samsung says.

When it comes to phone thefts, London is the European capital. According to police figures from last year, some 80,000 smartphones were stolen — an increase from 64,000 in 2023. That equates to one phone snatched every seven-and-a-half minutes, or roughly 192 devices every single day.

Samsung will spotlight several features already available on its smartphones that must be enabled before owners are shielded

The publicity blitz was created to support the UK Home Office's ongoing work to prevent mobile phone thefts. Samsung will spotlight several features built into its operating system to deter thieves and prevent data theft.

These include:

  • Theft Detection Lock: First released on Google Pixel smartphones, this system combines data from sensors inside the device and machine learning algorithms to determine if the smartphone has been snatched from your hand. If triggered, it instantly locks the screen to prevent access — even if you were using the phone when it was grabbed by the thief. Google started work on this system on advice from staff in its London office who were victims of theft.
  • Offline Device Lock: This tool that automatically locks the screen when your device is disconnected from the network for an extended period, something that's associated with phone theft — usually as the criminals are trying to ship the handset outside of the country where it can be stripped down and sold for parts.
  • Remote Lock: A tool that allows users whose devices have already been stolen to remotely lock their phones, regain control of their accounts, and access recovery options.
  • Identity Check (Added in One UI 7): Introduced with the latest mobile operating system release from Samsung, this anti-theft tool allows Galaxy smartphone and tablet owners to set requirements for biometric authentication when sensitive security settings changes are attempted in “Safe Places.” This blocks thieves from being able to make critical changes to your security settings, like the password or facial recognition needed to unlock the handset.
  • Security Delay (Added in One UI 7): When enabled, a one-hour delay is activated whenever changes to biometric authentication settings are requested. This is designed to stop criminals from making critical changes after it has been stolen. If your phone is unlocked when it's taken, this should stop further damage.

With all of these features enabled, Galaxy users should rest assured their data is safely under lock-and-key.

However, these clever features can only only reach their full potential if you actively participate and take time to enable them. With any luck, Samsung's efforts to reach out to 40 million Galaxy users will prompt a few more to enable these features.

Speaking about phone theft, Samsung UK's Mobile Experience VP of Product and Marketing, Annika Bizon said: "Samsung is deeply committed to working closely with the Home Office on the issue of mobile phone theft and related crimes and we’re in constant collaboration with our partners across the industry, to look at new and existing solutions to help combat this complex issue and ultimately help improve the safety of mobile phone users.

"Our recent One UI 7 update built further on existing protections with new anti-theft features such as identity check, biometric authentication and security delay, all featured in our latest Galaxy S25 series. These features have now also been rolled out into a range of models across our devices and further updates will follow.

"We must do everything we can to ensure the safety and security of our customers when they are using their mobile devices and we will continue to work hard to ensure our customers are aware of the wide range of security features available to them."

The latest campaign comes as the South Korean firm offered an early glimpse at its next mobile operating system, dubbed One UI 8. This new release is based on Android 16, which arrives with a highly-customisable new design.

One of the biggest new additions is something called intelligent multimodality, which means that Galaxy AI can analyse what's on-screen and factor in that context when answering your questions.

According to Samsung, this should make for more natural interactions with its AI assistant.

The Reminder app, preinstalled on every Samsung Galaxy phone, has been redesigned with a new layout that shows categories at the top, voice input, and reminder templates. Likewise, Quick Share has been redesigned too.

AI Select, which launched alongside One UI 7 and offers intelligent suggestions based on what you've highlighted — so selecting a video might bring up an option to convert it into a GIF and send it on WhatsApp, for example — is faster than ever. Samsung says some tinkering under the bonnet in One Ui 8 means it should activate instantaneously.

One UI 8 also supports Auracast audio streaming, which broadcasts audio to multiple devices and hearing aids. Samsung trialled the system in St Paul's Cathedral in a world-first test earlier this year.

One UI 8 is being tested at the moment on select Samsung Galaxy smartphones in the US, UK, Germany and South Korea, One UI 8 is set to roll out worldwide this summer with Samsung's new foldable phones, expected to be called Galaxy Z Fold 7 and Z Flip 7.

Below is the latest advice provided by Samsung to help if you're the victim of a theft.

How to remotely lock your Samsung Galaxy device:

  • Sign into Samsung Find using your Samsung account
  • Select your phone on the left-hand side of the page, then choose Lost Mode in the device details section
  • Create a PIN to unlock your phone if recovered, and enter it twice to confirm
  • You will have the option to add an emergency contact and a custom message that will display on the locked screen (It’s recommended to skip this step to avoid sharing personal contact details)
  • When you are ready, select the Lock button and verify your Samsung account to activate Lost mode
  • If your device is recovered, you can unlock it using the PIN that was created when setting lost mode on your device

How to remotely delete data on your Samsung Galaxy device:

How to remotely change your Samsung and/or Google account passwords:

  • It is recommended to change the passwords for your Samsung and Google accounts (or whichever accounts are linked to your device) by signing in through their respective websites
