Help Phone Security Issue - Installing Apps From Unknown Apps Keeps Switching Back to Yes

[cf1572]

Hi,

I have an UMI Diamond phone (Android 6.0). I have the Malwarebytes app installed. And it occasionally notifies me there is a security issue with 'Installing apps from unknown sources'. So, I go to Settings, Security and switch 'Unknown sources - Allow installation of apps from unknown sources' to NO, and the problem is temporarily fixed. However, it keeps switching back to YES because when I open Malwarebytes a few days later I am again notified that there is a security risk with 'Installing apps from unknown sources'.

So, why does it keep switching back to YES, and how do I stop this from happening?

Thanks

I'm not familiar with UMI, so I can't say with certainty that the manufacturer wrote something into the operating system that keeps Unknown Sources turned on. It may be another app you've installed, particularly if that app came from an unknown source.

If a feature like that is switching by itself and unpredictably, have you rooted and modified it all? Or it could be an issue or feature of the firmware, and something that Youmi has done.

If no other information comes up, you might want to contact them and enquire about it.
