    Third-Party Apps


    Technology keeps changing and it makes our phones susceptible to various attacks.

    The most common divisor by which your phone becomes vulnerable and you would possibly face data loss is the reason "third-party app downloads"

    You have to avoid downloading any third-party applications. Always install apps from Google Play Store or any other trusted sources.

    Do not download any APK on your smartphone because it may contain malware or trojan inside it which may lead to serious data loss

    You can simply avoid this just by disabling the unknown sources app install option. We usually enable this feature for unknown sources and forget to show them off.

    Only turn it on if you actually need any app on your phone that won't be available on the Google Play Store.

    The apps on the google play store are fully scanned, and do not contain any type of malware or trojans, and the data used here is also not shared publicly.



    We usually give permissions to many apps such as calling or storage although it has no link with all these permissions.

    Many of you have thought do these apps save our personal data in their server when we allow all the permissions?

    For example: if you have downloaded a game and it asked you for camera and location permission then guarantee there is something fishy.

    Sharing and storing personal data depends on the app's privacy policy and its terms and conditions, do the app share your personal data and the motive behind the sharing of data, etc.

    Many apps don't run on your smartphone until all the permissions are given to it, so avoid giving all the permissions to these unknown apps or uninstall them

    If you are using android 12 or above then you can check all the permissions that an app is usurping your smartphone.

    So please don't give all the permissions to such apps or find another for that app.
