Essential protections every UK buyer should set up on day one

The launch of the OnePlus 15 brings flagship performance and new software features, but it also opens the door to increased security risks that commonly appear when a high-profile phone first reaches the public. Cybercriminals often target new devices during launch periods because users are excited, installing apps quickly and setting up accounts without much caution. For UK buyers, taking a few key steps on day one can significantly reduce the chance of hacking, data theft or fraud later.

One of the biggest risks during launch week is outdated software. Early batches of new phones sometimes ship with pre-release firmware that receives several patches shortly after release. Installing all available system updates as soon as the phone is turned on is the most effective way to close known vulnerabilities before they can be exploited. These updates often include fixes for permission issues, security loopholes and stability concerns that could otherwise expose sensitive data.

Another risk comes from app permissions. During the excitement of setting up a new flagship device, users often install multiple apps rapidly without reviewing what each app requests access to. Hackers exploit this behaviour through malicious apps that ask for unnecessary permissions such as SMS access, contact lists or device admin rights. Carefully checking permissions during installation ensures no app receives more access than it legitimately needs, reducing the likelihood of data misuse.

Two-factor authentication is another area of concern. Many UK services still rely on SMS-based verification codes, but text-based authentication can be vulnerable to spyware or SIM-related exploits. Launch day is the ideal moment to switch your accounts to authenticator apps or hardware keys. These methods significantly reduce the risk of interception and ensure sensitive accounts remain protected, even if the device experiences a minor security flaw.

Setting up strong device-level protection is equally important. A secure PIN or password, paired with fingerprint or facial biometrics, prevents unauthorised access to apps and financial services. New phone owners often delay these steps in favour of quick access, but choosing a strong lock immediately protects personal data, banking apps and private files from both digital threats and physical theft.

App installation habits also play a major role in long-term safety. Sideloading apps or downloading files from unverified sources introduces one of the most common infection pathways. Even on launch day, it is best to rely exclusively on trusted app stores and verified developers. Unknown APK files or unfamiliar links shared through social media or messaging apps should be avoided, especially when the device is new and unpatched.

Backing up data securely is another essential step. Cloud storage, encrypted backups and account-level recovery options ensure that important files remain safe in case of loss, damage or a future security breach. Launch day is a perfect time to configure these features before the phone becomes filled with photos, documents and essential app data that might be difficult to replace.

Privacy tools built into the OnePlus 15 can provide additional protection when enabled early. Features such as app-locking, password-protected folders, background-activity controls and secure file management offer extra layers that help reduce exposure to unwanted tracking or unauthorised access. These tools are often overlooked by new users, yet they contribute meaningfully to overall device security.

Securing your network on launch day is equally important. Connecting the phone for the first time through safe Wi-Fi avoids the risk of eavesdropping commonly associated with public hotspots. Pairing accessories such as earbuds or smartwatches should also be done carefully, ensuring the devices come from trustworthy manufacturers and are updated with the latest firmware.

Remote-tracking and wipe features provide critical protection in cases of loss or theft. Setting up find-my-device services allows you to locate, lock or erase your OnePlus 15 if it goes missing. This serves as a final safety net, ensuring your data is protected even if the handset is physically compromised. Many users forget to activate this feature until it is too late, making it essential to configure on day one.

In summary, while the OnePlus 15 offers strong performance and modern software, no smartphone is immune to risk—especially during the vulnerable launch period. Installing updates, reviewing permissions, strengthening authentication, securing backups and enabling privacy tools all contribute to a safer long-term experience. For UK buyers who want peace of mind alongside flagship capability, following this launch-day security checklist ensures a smooth and protected start with the OnePlus 15.
