I accidentally discovered that my phone was under surveillance
Thread Content
I just took some photos and was about to send a message when I received some unclear messages related to them. These surveillance systems are amazing; the speed at which things happen is beyond imagination. Everyone can check their phones to see if there are similar situations; if such situations exist, it means that their activities are under surveillance.
In the era of big data, as mentioned online, when you talk to a friend about what you want to buy, Taobao and JD.com start to recommend products to you. . . .
The key is the path I took; I found it in the background files on my phone.
That one is okay, I guess. It’s similar to the navigation on your phone: the sports and health app on Huawei phones can be used while you’re running, and it will record your route
Turn off the GPS, or set it to turn on only when in use; or put the phone inside an aluminum foil bag, or switch to a Nokia phone
