Are you concerned that someone may have unauthorized access to your phone? Here's a quick guide on how to tell if someone is connected to your device. First, check your device's Bluetooth settings to see if any unknown devices are listed as connected. Additionally, keep an eye out for unusual activity, such as apps opening or closing on their own, or your phone behaving in unexpected ways. It's also a good idea to regularly check your data usage to identify any unexpected spikes that could indicate unauthorized access. Finally, consider installing a security app that can monitor your device for potential threats and alert you if anything suspicious is detected. By staying vigilant and taking these steps, you can help protect your phone and personal information from unauthorized access.
