I've been using Hotspot Shield to access other countries' Play Store since I've bought this phone. After some time of absence from using the VPN, I tried last night, and I'm unable to check the box "I trust this application". It is not greyed out even. So, I uninstalled the app and tried to install it again. Now I can't even install any VPN app ezcpet OpenVPN. I don't have Lux Brightness app or any other app like that installed. The phone is not rooted. Can anyone help me on this matter?
