Here's what to look out for: 1.). Unusual sounds on Calls -  If you hear a high-pitched hum, pulsating static, clicking, or beeping, these could be signs that your calls are being recorded.  Someone could have set up CALL-FORWARDING without your permission or CALL-RECORDING MALWARE may be on your device.  Hearing weird sounds every so often is likely normal--you may just need to fix a bad signal--but if it happens consistently, check the phone                                                                                                                                     2.). Your Battery Drains and Phone Overheats:   Does your phone overheat and battery drain quickly for no obvious reason?  This can happen when streaming video or playing games for long periods of time. But if it happens when the device should otherwise be at rest, it could be malicious software that constantly sends data back to whomever is tracking your phone.  Navigate to settings on the phone and see which apps are running down the battery the most.                                                                                                                    3.). Websites Don't Look Right:  Some forms of malware can infiltrate your browser by displaying fake web pages that look legitimate, then harvesting your login credentials when you enter them. Phishing scams like this are common because social engineering scemes work!  If the website you're on acts strange or looks different than it did before, close the page.                                                                                                                                                                                           4.). Your Phone Won't Shut Down:  If the phone has trouble shutting down, that could be a sign that it is being Tapped.  When turning off your phone, check to see if the backlight stays on even when the phone is powered off or if shutdown attempts fail altogether. Randomly turning off or rebooting is another sign of trouble.                                                                                                                                                                         5.). Unusual Text Messages:  Text messages that are full of gibberish or contain questionable links can be a sign that spyware on the device has been incorrectly installed. The program is trying to send instructions to your APPS and instead are coming through asss SMS messages.                                                                                                                               6.). Hijacked Cameras and Microphones:   Watch out for your camera or mic turning on randomly. If the camera light turns on when you didn't open an APP that uses the camera, the phone could be hacked. Some malicious software lets hackers access the camera even without turning the light on, so always DIG DEEPER.                                                                                                                                                                             High Data Use You Can't Explain:   Since spyware and malware routinely send information back to the hacker, it can use up a lot of your device's data. Higher than normal data usage can result in additional costs, especially if you don't have an unlimited data plan. Check your phone bill at the end of the billing cycle to see if the costs jump unexpectedly.  To check data usage, head to Settings  Cellular on iPhone. Android users can find the same options under Network and Internet or Connections settings. You can also set the phone to send warnings if data usage goes over a certain threshold.                                                                                                                                                                           8.)
