I don't think is there so much junk on your phone to use a Junk Cleaner, I think any Junk Cleaner App is Junk. ..lol..
what do u mean by effect?
the Z1 is a fast phone u wont notice any slow down or speed up even with 1gb of cache...
Come to think of it I should probably get rid of my cleaner app. i dont even use it at all.
Android its not based as Windows where you have to clean up dead icons, unused files or anything like that. When you installing something just remember to delete the folders after uninstall it, that's the only thing. In performance there is no advantages at all to use Cleaner Apps.
