Gos is good. It is a solid os. I like it a lot. I have a lot of freedom that I don't have on other phones. But it is also just android. other brands like samsung added a lot of goodies to their os. It is a phone, it works, it's alright. It took me a while to understand that graphene's exploit protection slows down apps. I disable that for all important apps like osmand where speed is crucial. Osmand is still slower than on an iphone 6. Do I have to use it security wise? No, but I like supporting it. Will my next phone have gos as well? Yes. It has no annoyance on it. There is no unwanted app or anything. That's amazing.
