I only have an Android phone and my Microsoft Defender constantly turns itself off , I went and bought a new phone and Sim thinking it was some kind of bot or virus but it still does it on the new phone.

    Diana Blackwood,

    It’s a known issue that Microsoft Defender for Android can appear to “turn itself off” or disable features like Web Protection, even on new devices. This is usually not caused by malware but by Android system behaviors and app settings.

    To troubleshoot refer to:
