I recently read an article about location-based apps such as "Girls around Me". This app can share your location without notification. How can I prevent it?

With the development of technology, some large companies now install cell phone signal jammers in the work area. This cell phone signal jammer completely separates interference, WiFi and phone functions, improving employees' work. Especially in large conference rooms, 3G/4G cell phone blocker can be used to prevent meetings from being interrupted and meeting information from being stolen, which not only improves efficiency but also improves the protection of some information. Don't let competitors or criminals benefit.

In fact, the "Girls around Me" app uses Foursquare check-ins and Facebook data to make it easier for boys to track girls around, but the purpose of tracking is unclear. There is a slogan on the app's website that suggests how to use the "Girls around Me" app, which is all about finding your lover or finding your one-night stand.

Although Foursquare has withdrawn API access and the "Girls around Me" app has also ended its existence, there are many other apps that may be creepy. An app called Color will hand over your social media photos to strangers, even if you don't want to share them. Another app, Find My Phone, could be used in a very abusive way by any of your ex-partners.

Or, you could use the app to find the nearest restaurant that has a dinner date listed. The app uses your smartphone's GPS tracking module to perform such services, but it also shares your location data with third-party companies to keep you informed of your smartphone, which can be very annoying. You can also place ads based on ads.

Scrambling devices are very simple devices that use basic technology provided by the phone itself.

Will a jammer attract lightning when it is turned on?

Will using a signal jammer outside a building, in an open space, during bad weather attract lightning?

It would be great to be able to call anyone at any time. Unfortunately, restaurants, movie theaters, concerts, and churches are all affected by the surge in cell phones. Because not all cell phone users know when to stop calling. 3G2G signal jammer phones are portable and can be put in a pocket or bag to go out, making them a useful tool to stop people from calling in the above locations.

As for those lightning bolts, there is a small chance that they will hit the GPS jammer. The chance is about the same as the chance of lightning striking a cell phone in the same area, so if there are no lightning rods around, it's probably best to avoid using a handheld jammer in your pocket for safety reasons.
