Security master app I think this app is very good to keep personal data safe. I am using this app myself, I think this app is very secure. In this you can keep your videos / photos / apps and file up to date.
A lot of system of this app is that if this application is uninstalled from your device then you will understand that my data will be deleted but will not be deleted.When you install 3Sapp, autometic all the data will arrive. This is the best thing in this app and I am using it for 4years, and I will continue to do it.
Thank you so much.
