Each year the mobile companies keep on coming with new and updated smart phones and most of the time this comes into our budget and is affordable. So often we move from our old device to the new one and the old ones serve no purpose.

However it is best to make some use of the old device. There are many ways in which we can repurpose a old Smartphone. Top 10 use of a old Smartphone not in use any more can be

1. In-Car GPS and navigation

An old Smartphone can act as a GPS device for your car, you can permanently place it in your car, on the car charger or directly to the car battery. You can have Google Maps installed in it, which can be further used for the navigation purpose.

2. As a surveillance device

Keep an eye on your home, office or kiddos by transforming your device into a Web-connected security camera. Now a days the camera quality is too good in any mobile devices. Just download the free IP Webcam app and follow its instructions -- and, within seconds, you'll be able to peek through your device's lens from any compatible computer browser.

3. Wireless hotspot

You can use it as a wireless hotspot and further can be used to connect other devices and computers or any other mobile device.

4. Digital photo frame

You can use it as a digital photo frame for a family or friends picture. You can have your marriage picture or your kids, or your complete family picture in auto display.

5. Universal remote controller

Some of the mobile devices can be little modified and can used as a remote control

6. Video chat for whatsapp and IMO apps

Can be used as a landline device always kept at home and further used as a video call device.

7. Turn it for Kids education and gaming device

Awesome apps are present on the Google apps these days especially for the small kids which can be highly useful can be used for educational purpose as well. Teach them how to use it, how to dial a number or read a story.

8. Use it as a reader, just like kindle

Can be used as a reader, for reading books. Load up your old Android device with only the apps you need for reading -- Google Play Books, Amazon Kindle, Pocket or whatever tickles your fancy -- and keep it by your nightstand.

You can also borrow books from your local library. Check with your nearest branch for information on how to do it, or download the free OverDrive app, which is used by a variety of libraries, schools and other institutions.

Be sure to disable notifications from Gmail and any other native services -- heck, even switch it into airplane mode once you've downloaded the content you need -- and you've got the equivalent of a dedicated e-reader without all the usual phone or tablet temptations.

9. As a video player in your car

Can be placed in the car to play video and listen to songs. You can save yourself the hassle of futzing around with your current phone every time you want to listen to music on the road by making your old device an always-available car-based MP3 player. Load it up with all the music you want, then plug it into your car's power port, connect it to the stereo via either Bluetooth or the 3.5mm headphone jack, and send that old in-car CD player (or, dare I say, cassette deck) into permanent retirement.

• Turn it into a high-tech e-clock
