What can an old mobile phone do?

Nowadays, digital products such as mobile phones are upgrading too fast. I just bought a new mobile phone with a month's salary hollowed out, and the latest model will come out in a few days. Moreover, the eliminated mobile phones are reluctant to throw, and they are also bought at a high price. Instead of selling old mobile phones, it is better to turn waste into treasure and give full play to the remaining waste heat. The following

1, home security camera

When you no longer need to carry your old mobile phone or tablet with you, you can put it in a corner of your home or on the windowsill for home security monitoring or baby monitor. At present, there are a large number of related applications on the market that can achieve this goal. It is not as powerful as iCamSpy, Presence and Manything, and can help you protect your property or remotely monitor your baby's condition from other places.

2. Remote control

For smartphones or tablets, there are actually many control methods. Through special applications, they can be used as remote controllers for SLR cameras, which are very suitable for self-portraits. Including Apple and Chromecast TV sticks, all have special applications to control them.

3.MP3 player

Before the popularity of smart phones, we will all use MP3 players. Although these smartphones or tablets have been eliminated, they can still play stereo music files. If you want to save electricity for your new mobile phone, you might as well use your old mobile phone as an MP3 player, and you don't have to worry about calling to disturb your music enjoyment.

4. Electronic photo frame

Its old tablet can also be used as an electronic photo frame at home, as long as you choose the appropriate application, provided that the power supply is connected and the automatic screen locking is disabled. Dayframe is a good tool on Android platform, which can import all kinds of photos from your social network into photo frame album, and Picmatic is doing the same thing on iOS platform. The other two platforms have other applications that can do the same thing.

5. Electronic reader

Although mobile phones and tablets are different from e-readers and not E-Ink screens, they are more conducive to our reading. Both iBooks and Play Books can synchronize the official list of Kindle or Kobo, supporting cross-device synchronization. You can also log on to Instapaper or Pocket with your old mobile phone or tablet, which should be used for online reading.

6. Baby toys

If there are children at home, then old mobile phones or tablets are very suitable for them to use as toys. Obviously, there are many applications and games specially designed for babies in the app store, and special home control software can ensure that children will not be too addicted. More importantly, even if the old equipment is knocked over by the baby, it will not be uncomfortable.

7. Barometer

We all know that the latest iPhone has a built-in air pressure sensor, but even a mobile phone can check the local weather and climate by installing an application. This function can be realized by barometer including iOS platform and altimeter of Android. You'd better hang them on the wall if you can.
