The best The best!!!! wen u are not using ur phone much but needs it to just use for in/out calls (like wen ur traveling) keep it on extreme mood. its just awesome the way it saves battery. also make sure u don't use battery saving mood during a time u need internet or graphic acceleration app/game. Cosmos wil try to close or limit those apps. don't blame the app for doing its job afterwards. :) also i found it useful in balance mood coz it closed unwanted apps and frees my ram. my phone preforms really well now. :)
Very Nice app This is a nice app. It not only cleans trash files but provides many other facilities of unistalling, moving apps & hide apps and folders through PIN protection. There are some major shortcomings in Privacy & Lock process. When we open camera or a social site, it shows all the contents (Photos & Videos) hidden. Second, if someone disables cosmos, password & PIN protection disappears and everything goes visible to all.
Very good App. Lock is very good. Only problem with it is, it flashes again and again after some time. It gets unlock for all app. If it is set for never lock. Please fix it. Battery saver need to be checked but not looks effective.
Needs some adjustments It is a great system and I like being able to secure certain apps but I don't like how after a few minutes it asks me to enter my password again and continues doing that. If that glitch could be fixed I would enjoy it. In fact as I was typing this comment it went to the password screen on me.
The worst The worst battery saver ever. My battery lasted a whole work day until I downloaded this app. Now it doesn't even last 3 hours... don't download, or you will have to replace battery...
