What do you all do with your smartphones?

1.TV box.

Some people's TVs may still be old-fashioned nowadays. They can't enjoy the smart box if they can't connect to the internet, but they have no plans to replace the TV. You can use your old smartphone to turn your old TV into a more stylish smart TV now.

Second, the car navigation system.

Now, as long as all smartphones have GPS location services, we can use this to turn idle old smartphones into car navigation systems. On the old phone in advance** and install popular navigation software, such as AutoNavi navigation, navigation, etc., connect wifi at home to connect all offline data packages** to the old phone. Later, as a car navigation system, you can use GPS location services for precise navigation without the need for an internet connection.

Thirdly, as an old man.

Generally, the configuration of our idle old mobile phones is good. We can install desktop software such as Ruyi Advanced Desktop and 91 Advanced Desktop on the idle mobile phones of the elderly to simulate or virtualize the elderly for the elderly.

Fourth, as a wifi repeater.

If you have a weak wifi signal in local areas of your home and individual rooms and need to extend the transmission distance, your idle old mobile phone will come in handy as a repeater (wifi amplifier) for home wifi.

5. As a wireless speaker for PC.

Some people may not have speakers on their computers, and when you want to listen to the sound of your computer**, you can make wireless speakers from your old and idle phone. The method is to exchange audio streams point-to-point through wifi, so that the sound on the phone and computer is made. Soundwire software required.

Those who are still on the computer, should they change their thinking? You can use idle old smartphones to build your ** artifact, take advantage of the ultra-low power consumption of mobile phones, and leave it on forever. The method of faction change is to insert a 32G or 64G TF memory card into the old mobile phone that is not used, and then let the mobile phone be connected to the charger all the time.

Generally, the equipment of old mobile phones is not high. Generally, the running RAM is 512M - 1G, the larger one is 2G, and the storage ROM is 2G - 16G. These conditions are completely sufficient, because the ****** does not store data permanently, but only stores cached files temporarily, so the storage space requirements are not high.

1.As a surveillance camera. Whether it's an iPhone or an Android phone, you can install software to turn it into an "internet security camera", including Athome Video Streamer, Splashtop Camcam, and more, which can not only call up the front and back cameras of your phone for monitoring, but also view real-time monitoring** on other phones, tablets, or PCs for more comprehensive home security.

2. As a special car navigation system. Buy a good car mount and cigarette lighter power supply, and you can use your old smartphone as a dedicated car navigation system. We can install mainstream navigation map apps on our phones, and ** offline maps, so that even if the phone does not have a SIM card installed, we can achieve accurate navigation.

Of course, it's also easy to update the map, so you can always take it home and connect it to the wifi network, or even use your existing phone's data network as a wireless hotspot.

3. As a webcam or a dedicated chat tool. By installing PC camera applications, we can also turn our Android phone into a chat camera for our computer, which is very convenient. If you don't need to use PC** to chat, you can also buy a mobile phone universal stand that can be fixed in shape, and place the idle mobile phone on the desk as a special **chat tool, you can log in to QQ and other IM applications for **chatting.

4. As a remote control. If you don't want to worry about a bunch of remote controls and your old phone happens to have an infrared emitter, you can turn it into a universal remote control to operate large and small appliances in your home. Third-party universal remote control applications are usually compatible with thousands of models from well-known brands at home and abroad, including TVs, air conditioners, stereos, and more.

If your phone doesn't have an infrared emitter, you can also look for some brands of dedicated apps to achieve remote control.

5. As a computer assistant. If you don't find the mouse easy to use, or need to add a laptop-like touchpad-like function to your desktop computer, you can also install an app to turn your smartphone into a touchpad or an external keyboard for your computer, and you can operate smoothly through the phone's touchscreen.

When you're thinking deeply or immersed in a task, your phone can often disrupt your concentration and concentration. However, if you use your phone normally, it also has potential problems. There may even be some questions that you don't know about yourself.

I had an experience that revealed some of the untold secrets of my phone. It was night, and when I was at work, my phone rang, I picked it up and looked at it, and somehow found that there were several unknown message notifications. So I started turning on notifications and checking messages.

When I opened a particular message, I found out that it wasn't a normal message, but a group chat message. Alas! It seems like I'm joining some group that I don't know about.

To figure things out, I opened the group, but soon discovered an awkward thing.

This group was created by my colleagues to pass on some personal information, including opinions about the company, gossip in the office, concerns about what they say being heard, and so on. I was so annoyed and angry that I didn't know why they created this group without inviting me and were still talking about me among my colleagues. I felt betrayed, so I decided to quit the group and adjust my work the next day to try to avoid too much interaction with these people.

This experience taught me several things. First of all, privacy is important. When we use smartphones, we tend to rely too much on technology and communication tools, but we can also be compromised by these tools.

Secondly, you need to always be vigilant, keep a clear head and realize that things around you may not always be as we think. Finally, if your phone is showing strange signs, such as an unknown notification message, it should be double-checked.

In short, this experience reminds us to pay attention to our phones and privacy. It taught me the importance of being vigilant and clear-headed. I hope my experience can help others avoid similar problems and make us re-examine our privacy and smartphone use.
