Hi, I am going to share my real experience after using app lock and gallery vault application.
Phone requires privacy for protecting it from unauthorised access. For this purpose, I installed app lock and gallery vault application in my mobile phone. I downloaded it from google play store on 8 th october 2016.
When I opened this app for first time, it asked me to setup password. I observed that after installing this app in my mobile phone, there are many advertisements are popping up. It is more complex because it asks us to allow accessibility in settings.
Along with this, performance of this app is not too good. Sometimes it fails to protect your privacy. Many times it opens without asking password. I am going to delet this app.
Developer should fix this problem.
