Repurposing also taps into the growing trend of sustainable tech use. By finding new uses for your device, you’re extending its lifecycle and getting more value out of your investment. Ready to breathe new life into that old phone? Here are nine ways to do it.

1. Turn It Into a Security Camera or Baby Monitor

Why It’s a Great Idea

No need to splurge on a fancy security camera or baby monitor when your old Android phone can do the job. With its built-in camera and microphone, it’s perfect for keeping an eye on your home, pets, or kids.

How to Do It

Download apps like BabyCam or IP Phone Camera from the Google Play Store. These apps let you stream live video, listen to audio, and even capture photos or videos remotely. Here’s a quick setup guide:

  • Install the app on your old phone.
  • Place the phone in a stable spot with a clear view of the area you want to monitor (e.g., a nursery or front door).
  • Connect it to a charger to ensure uninterrupted use.
  • Pair it with another device (like your current phone or laptop) to view the feed.

Pro Tip

For better performance, use a phone tripod or mount for stability. Apps like BabyCam offer two-way audio, so you can soothe a baby or scare off an intruder with your voice!

Why It Works

A 2024 study by CNET found that repurposed smartphones can perform just as well as mid-range security cameras, saving you hundreds of dollars. Plus, you’re using hardware you already own, making it a budget-friendly solution.

2. Use It as a Dash Cam or Android Auto Companion

Capture the Road

If your old Android phone has a decent camera, it can double as a dash cam for your car. Dash cams are great for recording road trips, documenting accidents, or capturing scenic drives.

How to Set It Up

  • Download a dash cam app like Dash Cam Travel or AutoZen.
  • Mount your phone on your dashboard or windshield using a car mount.
  • Connect it to a car charger to keep it powered.
  • Start recording! Most apps offer features like loop recording and automatic saving during sudden stops.

Android Auto Alternative

If your car doesn’t support Android Auto, your old phone can bring a similar experience. Apps like Car Launcher or AutoMate simplify the interface for quick access to navigation, music, and calls.

Expert Insight

According to a 2025 review by TechRadar, repurposed smartphones can rival dedicated dash cams in video quality, especially if your old phone has a high-resolution camera. Just ensure it’s securely mounted to avoid distractions while driving.

3. Transform It Into an eBook Reader

A Distraction-Free Reading Experience

Love reading but hate the distractions of social media notifications? Turn your old Android phone into a dedicated eBook reader for a focused, Kindle-like experience.

How to Get Started

  • Download eBook apps like Amazon Kindle, Google Play Books, or Moon+ Reader.
  • Disable notifications to minimize distractions.
  • Enable grayscale mode (available in most Android settings) to reduce eye strain and save battery.
  • Consider using a minimalist launcher to simplify the interface.

Why It’s Awesome

A 2023 survey by Pew Research found that 32% of adults prefer eBooks for convenience. By repurposing your phone, you get access to millions of books, comics, and magazines without buying a new device.

Bonus Tip

Pair your phone with a Bluetooth keyboard for note-taking or highlighting passages, making it a versatile tool for students or avid readers.

4. Make It a Handheld Gaming Console

Gaming on the Go

Why drain your primary phone’s battery when your old Android can handle your gaming needs? Whether you’re into casual games or retro classics, your old device can become a portable gaming console.

How to Set It Up

  • Download games from the Google Play Store or use cloud gaming services like Xbox Cloud Gaming, NVIDIA GeForce Now, or Steam Link.
  • For retro gaming, try emulators like RetroArch for classic Nintendo or PlayStation games (ensure you own the original games to stay legal).
  • Pair a Bluetooth controller for a console-like experience.

Why It Works

A 2024 report by Newzoo highlighted that mobile gaming accounts for 51% of the global gaming market. Your old phone, even if it’s not the latest model, can handle many games or stream high-quality titles via cloud services.

Pro Tip

Optimize battery life by lowering screen brightness and closing background apps. This ensures longer gaming sessions without constant recharging.

5. Turn It Into a Digital Clock or Photo Frame

A Stylish Bedside Companion

Transform your old Android into a sleek bedside clock or digital photo frame to add functionality and charm to your space.

How to Do It

  • For a clock, download an app like Flip Clock for a minimalist, customizable display.
  • For a photo frame, use Google Photos’ slideshow feature or an app like Fotoo to display images from cloud storage.
  • Mount the phone on a stand (preferably with wireless charging) for a polished look.
  • Customize settings like slideshow transitions or background music for a personal touch.

Why It’s a Great Idea

According to a 2025 article by The Verge, digital photo frames are making a comeback as nostalgic home decor. Your old phone can replicate this experience for free, saving you $100+ on a dedicated device.

6. Repurpose It as a GPS Tracker

Keep Tabs on What Matters

Your old Android phone can serve as a reliable GPS tracker for your car, bike, or even your child’s backpack, thanks to Google’s Find My Device feature.

How to Set It Up

  • Enable Find My Device in the phone’s settings and sign in with your Google account.
  • Place the phone in a secure location (e.g., car glove compartment or backpack pocket).
  • Use a small power bank to keep it charged.
  • Access the phone’s location via the Find My Device app or website.

Expert Tip

A 2024 study by PC Magazine noted that smartphone-based GPS tracking is nearly as accurate as dedicated trackers, making this a cost-effective solution for monitoring valuables or loved ones.

7. Boost Your Wi-Fi as a Signal Extender

Eliminate Dead Zones

Struggling with Wi-Fi dead spots at home? Your old Android phone can act as a Wi-Fi repeater to extend your network’s range.

How to Do It

  • Check if your phone supports simultaneous Wi-Fi and hotspot functionality (most modern Androids do).
  • Connect the phone to your primary Wi-Fi network.
  • Enable the hotspot feature and place the phone in an area with a weak signal.
  • Connect other devices to the phone’s hotspot for improved coverage.

Why It Works

While not as powerful as a dedicated Wi-Fi extender, this method is free and uses hardware you already own. A 2025 review by CNET confirmed that smartphone hotspots can effectively bridge Wi-Fi gaps in small spaces.

8. Use It as a Second Screen for Your PC

Boost Productivity

Need more screen real estate for work or multitasking? Your old Android phone can serve as a second monitor for your PC or laptop.

How to Set It Up

  • Download Spacedesk on both your phone and computer.
  • Connect the devices via Wi-Fi or USB (USB is more stable).
  • Extend your desktop to the phone’s screen, allowing you to drag apps or windows to it.

Additional Uses

You can also use your phone as a webcam, speaker, or microphone for your PC with apps like WO Mic or DroidCam.

Why It’s Useful

A 2023 productivity study by Forbes found that dual-monitor setups can increase efficiency by up to 30%. Your old phone’s display, especially if it’s large, can make a surprising difference.

9. Repurpose It as a Portable Storage Device

A Flash Drive Alternative

Even if your old Android phone is slow or has a cracked screen, it can still function as a portable storage device for files, photos, or videos.

How to Do It

  • Connect the phone to a PC, laptop, or gaming console via USB.
  • Enable file transfer mode in the phone’s settings.
  • Use it like a USB flash drive to store or transfer files.
  • For wireless transfers, use apps like AirDroid or Google Drive.

Why It’s Practical

Most Android phones from the last decade have at least 16-32GB of storage, rivaling many USB drives. This makes it a handy backup solution for important files.

Bonus: DIY Projects for the Adventurous

Feeling crafty? Your old Android phone can be the heart of countless DIY projects. Here are a few ideas to spark your imagination:

  • Smart Mirror: Use your phone as the display for a DIY smart mirror with apps like Magic Mirror.

A 2025 report by MakeUseOf highlighted that DIY tech projects are gaining popularity as a way to learn new skills and save money. Your old phone is a perfect starting point for experimentation.

Tips for Success

To ensure your repurposing project goes smoothly, keep these tips in mind:

  • Update the Phone: Install the latest available software to improve performance and security.
  • Factory Reset: Clear personal data before repurposing to protect your privacy.
  • Optimize Battery: Use a charger or power bank for tasks requiring constant power.
  • Test Apps: Not all apps work perfectly on older devices, so test a few options to find the best fit.

Why This Matters: The Bigger Picture

Repurposing your old Android phone isn’t just about saving money—it’s about sustainability. The Environmental Protection Agency (EPA) reported in 2023 that e-waste is one of the fastest-growing waste streams globally. By giving your phone a new purpose, you’re reducing waste and contributing to a greener planet.

Plus, it’s a chance to get creative and make the most of what you already own. Whether you turn your phone into a security camera, eBook reader, or portable storage device, you’re unlocking its hidden potential.
