If you think that someone might have gained access to the iPhone, conduct a complete search of all of the apps on your device and see if there are any apps you are unfamiliar with. The presence of unfamiliar apps you do not recall downloading is a great reason to install a mobile security app, since unfamiliar apps could be an indication that someone else has had access to your device.
For someone to monitor your iPhone and access the data of your iPhone, he or she might have to install snooping software on the device. If someone has access to your Apple ID via the iCloud password, they can easily track your iPhone using a spying app. If you had a weak password, then someone could guess it, and could potentially gain full access to your phone.
We tend to use the same password across accounts, and although this might be easier, it really opens up all of your devices to hackers and other security issues. One of the easiest ways to prevent someone from tracking your iPhone is by changing the passwords that you are using. When changing the password, be sure you do so for each and every service that you signed up to on your iPhone, as well as making sure no one else has access.
Most importantly, ensure you turn on two-factor authentication for your Apple ID, making remote logins impossible unless someone has your iPhone in hand at the time. You should always use a passcode on your devices, so if someone is going to locate your iPhone or iPad, they are going to have to have your passcode or a fingerprint in order to gain access to your device. With iPhone devices, all someone needs is your Apple ID and password to get into your gadget. While it is possible for certain apps on your iPhone to access the location, it could also be a sign that someone has installed a tracking app on your iPhone.
Hackers are not the only culprits, sometimes a former partner, or an unsavory parent with physical access to your device, can install a tracking app which is covertly monitoring your location, messages, and calls. If someone has hacked into your phone, they may be able to access all your private details, photos, videos, and may also track your physical location. Even if someone has just one minute access to your iPhone, then they can view your whereabouts through your phones settings mentioned earlier. If someone is snooping on your phone using any apps such as the Parental Control apps, the spyware is hidden in plain sight.
If you own an Android device, then the person that wants access to your phone could be sending you the link for installing a spying app. Once you click the link, a spy app is installed on your Android device, giving you access to the phones activities. If your phone has been compromised using a spy app, that is deleted as well. Keep in mind, the changes do not remove any tracking or spying apps that might have been installed on your device, but they do prevent them from sending information to anyone.
If anyone has installed a secondary app on your hand-held device, you should be able to see it on the top list. If you see something that does not belong, or even on an older device that you do not own anymore, choose what does not belong and click Delete from account. If you spot anything out of the ordinary, such as an unowned device, you may want to remove the out-of-the-ordinary.
If this is the case, and you did not configure the device to allow anyone else to log in, click “Reset Face ID” and re-run the sign-in process (it takes seconds). If you are getting frequent lockouts, you may want to look into whether you are getting any unwanted snooping software on your iPhone.
Do not forget to disconnect from public Wi-Fi after you stop using it; turn off your Bluetooth when not using it, since that too could be an access point for hackers; lock your phone with a passcode or lock screen; never leave your phone unattended, or allow someone you do not know to use it; routinely check which apps are on your phone, and check whether any are ones you do not recognize; and do not open any suspicious messages, links, or files. Check out our guides on how to delete unwanted apps; Inform friends and contacts, and direct them to ignore suspicious messages coming from you ; Stop exposing your personal hotspot while out in public, as it makes it easier for hackers to compromise your device ; Restore your phone to factory settings. Remember to not store passwords or login details for banking apps and other sensitive accounts.
A person could install such an app after directly logging into your device; you could be exposed to malware through a public Wi-Fi network or charging stations. It is also worth noting that hackers may hide the application (called Cydia) although the device is in fact jailbroken. If you do find an app called Cydia on a device, it is pretty much certain your phone has been jailbroken.
This is a bit more advanced, but if you noticed any strange apps on your phone that were not there before (namely, an app called Cydia), it probably means that your iPhone has been jailbroken, and it is a fairly safe indication that you have been jailbroken. One possible way of knowing whether or not an iPhone is jailbroken is by going into the Spotlight search page (swipe down from your screen) and searching for the Cydia app, this is a possible indicator your device may be jailbroken. If your phone has certain apps installed that seem incorrect, or you cannot recall installing them, it is possible your iPhone has been jailbroken.
If you lost your iPhone, you can select another iOS device to locate your iPhone using the Find My Phone app. The Bluetooth location function on the iPhone means that you can locate a disconnected iPhone if it is turned on, and you can use the Find My App to find your iPhone when it is turned off using its last known location.
How do I know if my iPhone is linked to another device?
You can view every device that is currently signed in with your Apple ID from the Devices area of your Apple ID account page, including Android devices, gaming consoles, and smart TVs: Select Devices after logging in to appleid.apple.com.
