Not sure ... I killed it immediately. I dont want anything on my device that allows remote access to my cameras. That "own background" feature may be used to do other things. When someone discovered hackers found a way to exploit the feature it will be too late.
I can understand your view and thats why my protection is 2 fold.
1, Read the permissions and make sure it doesn't do something that is completely out of the applications scope (This is where App Ad detector play a large role)
2. If something has access to a feature that I can see why yet I dont trust it, block its internet access (MIUI is great for this)
If the app fail for any reason of the above 2 methods used then I can live without it. (IE: use something I don't like but needs internet to function)
To help with my choice of finding apps I also follow 2 rules as well:
- Where does it gets its money from? If its not open source(where I can see the code for myself) I am the product not the customer, and
- I always only use apps based on review & recommendations. I never install something If I did not see a review of it from a trusted source.
Above never failed me yet.
