That's interesting. Thanks for the information.

I'll give it an install tonight. I'm curious to play around with it anyway and if I make minimal use of it, it should be pretty secure by it's use case.

Yes definitely more secure than stock, it is actually staggering to compare some of the features like ability to give apps access to only a selected set of contacts/files which as far as i know is still not on base android. whatsapp for example gets ALL of your address book or nothing (limiting usability) on other OS but on Graphene i can give it just 10 whatsapp-only contacts. I dont know how long the 5 will keep getting updates but for all I know it will be some years. the installation process is surprisingly the easiest of any mobile os I have ever encountered, you will be impressed!
