I made a small engraving manual from the same mobile for to freeze, disable, to backup android applications, delete cache files or orphaned which can be removed without problem.
We may also remove startup applications that do not want to start with android or spend normal applications to system applications so they can have more permissions and expand application options.
To achieve this, We need to be root our mobile or tablet.
We need to install the application System Cleanup for optimize your android and remove all those applications that install trash factory operators and companies as samsung, etc….
An application that also serves as accompaniment is Startup Manager, you do not need a manual, as it is just click on the – an app to disable the starter.
This is an example of frozen applications I have on my Nexus 4
