How to use idle mobile phones?

I think we can use an idle mobile phone as a "universal remote control".

Mobile phones are items that are updated quickly. I believe many people don't know what to do after the "eliminated" old mobile phone is replaced with a new one. How can we give full play to its role? Before it's too late, I'll teach you how to use old mobile phones that some insiders "revealed":

No.65438 +0 small coup-used as "universal remote control"

At present, there is an "infrared" function attached to the upper part of the market. If there is a mobile phone with this function, it can be used to "replace" the remote control. Most families have many household appliances, a considerable part of which need remote control operation. Therefore, it can kill two birds with one stone to use the old mobile phone with "infrared" function as "universal remote controller" and realize "one machine" to operate all kinds of remote control home appliances.

The second coup-used as a "car navigator"

Usually, smart phones have basic GPS navigation functions. Unwanted old mobile phones can be used as a car navigator for at least several hundred dollars by downloading and installing relevant professional navigation map software. Moreover, you can download the "offline map" in your mobile phone. After a series of operations, the old mobile phone without network or SIM card can navigate according to the offline map information.

The third small coup-used as a "wireless surveillance camera"

With the development of cloud technology, cloud monitoring came into being. For many families, "cloud monitoring equipment" plays a very important role, because it can prevent many accidents to a certain extent, and it can also let users know more quickly when an emergency occurs. It is an effective safety protection measure. Therefore, we can also make full use of the old mobile phone and let it act as a "high-definition camera" to monitor the situation at home remotely. This is also a way for mobile phones to "turn waste into treasure".

The fourth small coup-used as an "e-book reader"

With the development of science and technology, compared with the "trouble" of traditional books, the "convenience" of e-books makes many people "abandon" traditional paper books. Reading e-books on mobile phones is also a relatively environmentally friendly behavior. Therefore, the old mobile phone can be used as a "professional e-book reader", which can not only meet the reading needs, but also solve the power problem when using the mobile phone.

Tip 5- Use it as a "music player"

Music is the existence recognized and followed by the public. Most people often use their mobile phones to listen to songs, so they can use their old mobile phones as a special "music player" to listen to songs anytime and anywhere without being disturbed by text messages and calls.

The sixth trick-used as a "homemade SLR"

Nowadays, the camera function and effect of smart phones are generally high. If the camera function of the old mobile phone is acceptable, you can buy some cameras, brackets, selfie sticks and other related accessories, and you can turn the old mobile phone into a "new SLR" in minutes. Although the effect is certainly not as good as that of a SLR camera, it will be much better than the original mobile phone, which is enough to act as a "small SLR". Wouldn't it be beautiful?

Step 1: Before selling, be sure to delete private information.

Perhaps everyone is mainly worried that some personal photos and videos in their mobile phones, financial apps, mobile payment and other software will be recycled by criminals, and then the data will be recovered by technical means, thus stealing some of our private information. In fact, we don't have to worry too much, and we can't generalize. We just need to figure out which data will be leaked and which will not. Then for the part of the data that will be leaked, we can erase the private data through some necessary processing methods.

Under normal circumstances, after the mobile phone is replaced, most of us will gradually reduce the frequency of using the old mobile phone. Perhaps the use and storage of many key data (such as Alipay or WeChat payment) will be transferred to the new mobile phone, and the information value on the old mobile phone will gradually decrease. Some app and payment-related identity information, even if restored by others, has a low probability of directly revealing privacy. In addition, the current version of the mobile APP is updated very quickly, and the personal user information recovered from the second-hand mobile phone may be difficult to use in the new payment. So in fact, we don't need to worry too much about this.

In this way, the biggest risk of privacy leakage is only some photos or videos related to your identity. Then we can use the following methods to clear personal information before selling:

1. Delete personal information by restoring factory settings and deleting old mobile phone files;

2. Download the "file shredding" software to shred personal information (the specific method is not detailed here, you can search and download it online);

3. Overwrite and copy the old mobile phone. The specific operation method is: connect the mobile phone to the computer, first delete all the contents of the mobile phone, then write (copy and paste) new big files (big files unrelated to personal information) into the mobile phone, then delete and write again, repeat two or three times, and try to fill the space every time. This can ensure that the personal information and traces in the old mobile phone are completely removed. We can sit down and relax.

Step 2: sell it on a regular professional second-hand platform.

If these two platforms resell second-hand mobile phones, there are two modes, that is, recycling them through the platforms and reselling them to those in need. Both modes are acceptable.

If you want to shoot fast, then use the platform recycling mode. The advantage of this model is that you only need to make an evaluation list on the platform, and then professionals will come to check the recycling soon, so that we can sell our mobile phones without leaving home, which is more worry-free. The disadvantage is that the actual transaction price of mobile phones is generally lower than expected, and you need to make some concessions on the price. After all, you can't have both!

If you want to set your own price and sell it at your favorite price, just leave it idle and wait patiently for someone to place an order. This model requires you to have enough patience and confidence. It usually takes a long time, and ten days and a half are normal. Of course, there are also quick shots, that is, you may be lucky and meet the right person.

But these two platforms, no matter which platform they sell old mobile phones on, will definitely make more money than changing pots with mobile phones.
