How to remove pre-installed apps from Xperia E?
If it came pre-installed with your phone then its a system app. You cannot uninstall it (unless you have your phone rooted, which i think you don't have). Best option for you is to disable the app. In this case, the app won't run and won't consume any CPU or battery (if that's your problem). If you are concerned about storage space running out then this won't solve the storage problem.
