What's the use of used mobile phones?

Nowadays, mobile phones are changed frequently, and the old ones are actually very useful. Unfortunately, many friends don't know how to use them. In the end, they either put them in drawers to eat ash or change stainless steel pots. In fact, this is a waste. Today, I will teach you how to use waste to make mobile phones alive again.

Function 1: Use as car navigation

Many families have bought cars as commuting tools, but many people are ignorant of the road, and those who are a little far away don't know how to get there. At this time, they need navigation to help, but the navigation in general cars is not very easy to use, like I like to use mobile navigation.

An idle mobile phone can be installed with a navigation software. When buying a mobile phone cradle, you should know that mobile navigation has a fast update speed, and it can identify congested road sections after surfing the Internet, which provides great convenience for travel. If the screen of the mobile phone is too small, it can be mapped to the central control screen of the car, which is very convenient.

Function 2: wifi relay

This function may not be known to many friends. Simply put, the current mobile phones are basically dual antennas, and the hotspot can be turned on again after connecting wifi. If your house is relatively large, you can put your mobile phone in a suitable place, then connect the wifi router and turn on the hotspot, which is equivalent to adding a wireless router.

If you have a large number of idle cards, congratulations, you can use your old mobile phone as a mobile wifi without occupying your own mobile phone. You can try it.

Function 3: As a set-top box, the mobile phone with

type-c interface can transmit sound and images, so it can be directly connected to the TV set, and the music or video on the mobile phone can be projected on the TV set, which can save the money for buying the set-top box, and the mobile phone can also download various video software, with very high selectivity.

Function 4: As a remote control

Most mobile phones such as Xiaomi and Glory have infrared remote control, which is equivalent to a universal remote control, which can match various household appliances. One mobile phone replaces several remote controls to solve many annoying problems, such as the battery is dead and the remote control can't be found.

the market is practical for those friends who like to forget things.

Function 5: Use as a monitor

It is estimated that many friends didn't expect it. It's actually very simple to use an old mobile phone as a monitor. Download a corresponding software in the application market, then plug in a fixed charger, aim the camera at the place where you need to shoot, and start the monitoring software. It can also transmit the monitoring picture in real time like an Internet surveillance camera.

The above lists five methods of waste utilization. It's not worthwhile to take a mobile phone outside and exchange it for two stainless steel basins. It's better to let it continue to exert its residual heat and sell it when it really breaks down.
