Secure Your Smart TV, Tablet, and Phone Before Connecting

Your home Wi-Fi is probably crowded with connected devices. Smart TVs, phones, tablets, laptops, refrigerators, robot vacuums, and security cameras may all be sharing the same network. The trouble is, most people plug in a new gadget first and worry about security later. Some never check the settings at all. That leaves the door wide open for hackers, data brokers, and intrusive companies.

Before you connect your next smart TV, tablet, or phone, take a few minutes to lock it down properly.

Why devices aren’t safe enough right out of the box

When a new device arrives, it is not a blank slate. It comes loaded with factory settings designed for convenience, not protection. Manufacturers want the unboxing experience to feel effortless, so they enable features like automatic connections, data sharing, and remote access. These make setup easy but leave you exposed.

Smart TVs are among the worst offenders. Many include a feature called Automatic Content Recognition (ACR), switched on by default. It acts like a fingerprint scanner for your screen, capturing everything you watch and sending that data back to the manufacturer. You agreed to it somewhere in the terms and conditions you skipped through during setup. Most people have no idea it is even there.

Tablets and phones bring their own risks. Despite privacy boasts from many hardware makers, lots of devices will share your location, accept connections from nearby gadgets, and back up your data to company servers, all by default.

Plus, your home network is only as secure as its weakest device. One poorly configured smart TV or an old tablet with an outdated operating system can give attackers a foothold into everything else connected to your router.

The 4 things to check before you connect

Before you connect any new smart TV, tablet, or phone to your home network, spend five minutes manually checking the settings. You do not need to be a tech expert. Focus on the areas that create the biggest openings.

Update the device and change default passwords

First, update the device and change any default passwords or PINs. A brand-new device may have sat in a warehouse for months, meaning it could already need a security update. Default credentials are also easy for attackers to find online.

Review privacy settings and app permissions

Next, review privacy settings. On a smart TV, look for Automatic Content Recognition (ACR) and turn it off. Depending on the brand, it may be listed under Viewing Data, Live Plus, SyncPlus, Smart TV Experience, or privacy settings. On a phone or tablet, check location, camera, microphone, and nearby device permissions.

Turn off features you do not use

Then, turn off connectivity features you do not use. Bluetooth, remote access, file sharing, and screen mirroring can all create openings when they stay on all the time.

Add a VPN for another layer of privacy

Finally, consider adding a VPN for an extra layer of privacy. A VPN encrypts your internet traffic, helping protect what your smart TV, phone, tablet, or laptop sends over the network. A trusted VPN has apps for many popular devices, and it can also run at the router level on compatible routers.

The full checklist below walks you through each step.

New device security checklist

Next time you bring home a smart TV, tablet, or phone, do this before you use it every day.

1) Put smart devices on a guest Wi-Fi network first

Before you connect the device, open your router app or router settings page. Look for Guest Network, IoT Network, or Device Isolation. Create a separate Wi-Fi name for TVs, speakers, cameras, and smart home gear.

Use WPA3 Personal if your router offers it. If not, use WPA2 Personal. Give this network a strong password you do not use anywhere else. Then connect the new smart TV or tablet to that network instead of the same Wi-Fi your work laptop uses.

2) Update the software before signing in everywhere

Install updates before you add streaming apps, email accounts, or payment info.

iPhone or iPad: Open Settings > General > Software Update > Download and Install. Then tap Automatic Updates and turn on iOS or iPadOS updates.

Samsung phone or tablet: Open Settings > Software update > Download and install. On some models, go to Settings > System updates. Settings may vary depending on your device’s manufacturer.

Other Android phone or tablet: Open Settings > System > Software update > System update > Check for update. The exact wording can vary by brand.

Samsung smart TV: Go to Settings > All Settings > Support > Software Update > Update Now. Turn on Auto Update, too.

LG smart TV: Go to Settings > All Settings > Support > Software Update > Check for Updates. Turn on Auto Update, too.

Roku TV or Roku device: Press Home > Settings > System > Software update > Check Now.

3) Change default passwords, PINs, and device names

Do not leave factory passwords in place. Change the device PIN, parental control PIN, or purchase PIN if the setup screen offers one. Use a password manager to create and store strong, unique passwords. Use a long passcode on phones and tablets instead of a 4-digit code. Also, rename the device. A name like “Kurt’s Bedroom TV” tells more than you need to share. Use something generic like “Living Room TV” or “Tablet 1.”

4) Turn on account protection before adding apps

Before you sign in to Apple, Google, Samsung, Amazon, or Roku, turn on two-factor authentication where available. For Roku, set a PIN to help block unwanted purchases, subscriptions, and app additions.

Apple: Open Settings > your name > Sign-In & Security > Two-Factor Authentication > follow the onscreen instructions.

Google: Open your Google Account > Security & sign-in > How you sign in to Google > 2-Step Verification > Turn on 2-Step Verification > follow the onscreen steps.

Samsung: Open Settings > your Samsung account name > Security and privacy > Two-step verification > follow the prompts.

Amazon: Open the Amazon app > account icon > Your Account > Login & security > Two-Step Verification > Get Started > follow the prompts.

Roku: Go to my.roku.com > sign in > Device settings > PIN/Parental controls > choose when a PIN is required for purchases, subscriptions, and adding apps > Save.

5) Turn off ACR and ad tracking on smart TVs

Smart TVs often include Automatic Content Recognition (ACR). It can identify what appears on your screen for ads, analytics, or recommendations. Turn it off during setup or immediately after setup.

Samsung TV: Press Home > Settings > All Settings > General & Privacy > Terms & Privacy or Privacy Choices. Turn off Viewing Information Services. Also review Interest-Based Advertising and Voice Recognition Services.

LG TV: Press Settings > All Settings > Support > Privacy & Terms. Look for Live Plus, Viewing Information, or advertising options and turn off tracking you do not want.

Roku TV: Press Home > Settings > Privacy > Smart TV Experience. Uncheck Use info from TV inputs. Then go to Advertising and turn on Limit ad tracking.

Amazon Fire TV: Go to Settings > Preferences > Privacy Settings. Review Device Usage Data, Collect App Usage Data, Interest-Based Ads, and Automatic Content Recognition if that option appears.

Vizio TV: On newer Vizio TVs, go to All Settings > Privacy & Legal > Viewing Data and turn it off. On older models, go to System > Reset & Admin > Viewing Data. Also review Interest-Based Advertising and Voice Recognition Services.

6) Limit location, camera, and microphone access

Phones and tablets often ask for more access than an app needs. Give each app the least access possible.

iPhone or iPad: Open Settings > Privacy & Security > Location Services. Tap each app and choose Never, Ask Next Time, or While Using the App. Then review Camera, Microphone, Bluetooth, Contacts, and Photos in the same Privacy & Security menu.

Samsung Galaxy phone or tablet: Open Settings > Security and privacy > Permission manager. Review Location, Camera, Microphone, Contacts, Nearby devices, and Photos and videos. Change apps to Ask every time, Allow only while using the app, or Don’t allow when access isn’t needed.

7) Disable wireless features you do not use

Turn off Bluetooth when you do not need it. On phones, tablets, and TVs, also look for Nearby Share, Quick Share, AirDrop, file sharing, screen mirroring, and remote access.

iPhone or iPad: Go to Settings > General > AirDrop. Choose Receiving Off or Contacts Only.

Samsung Galaxy or Android phone: Open Settings and search for Quick Share. Tap Who can share with you, then choose a more private option such as Your devices or Contacts instead of making your phone visible to everyone.

Smart TV: Open Settings and check Network, Connection, or External Device Manager. Turn off remote access, screen sharing, or mobile device connection features you do not use.

8) Turn on lost-device protection

Set this up before the device goes missing.

iPhone or iPad: Open Settings > your name > Find My > Find My iPhone or Find My iPad. Turn on Find My, Find My network, and Send Last Location.

Samsung Galaxy phone or tablet: Open Settings > Security and privacy > Lost device protection. Turn on Allow this phone to be found, Send last location, and Offline finding.

Other Android phone or tablet: Open Settings > Security > Find Hub and make sure Allow device to be located is turned on. The wording may vary by brand.

For tablets used by kids or guests, write down the serial number. Keep it somewhere safe in case you need to report the device lost or stolen.

9) Remove apps you do not need

New devices often come with preinstalled apps. Delete or disable anything you will not use. Then install apps only from the official app store for that device.

On phones and tablets, avoid sideloading apps unless you know exactly where they came from.

On smart TVs, skip random free streaming apps with poor reviews, no clear developer, or strange permission prompts.

10) Cover everything with a VPN

A VPN adds a layer of privacy by encrypting your internet traffic before it leaves your device. That can help limit what your internet provider can see and add protection when you use public Wi-Fi.

Look for a trusted VPN that offers apps for phones, tablets, computers, and streaming devices. Some VPNs can also run at the router level on compatible routers. That option can be helpful because it may protect devices that do not support a VPN app, such as some smart TVs, game consoles, and connected home gadgets.

Once a router VPN is set up, connected devices can receive VPN protection automatically. Just remember that a VPN does not make you invisible online. Websites may still recognize you when you log in, share personal details, or use the same browser. Still, for everyday privacy, a reliable VPN can be a smart extra layer.

Key takeaways

The default settings most devices ship with are designed for the manufacturer’s benefit, not yours. Before you connect your next smart TV, tablet, or phone, take a few minutes to go through the settings, lock down what does not need to be open, and put a VPN between your network and the rest of the internet.
