My phone says I have 7 GB of apps but I only have 3 GB I am using Samsung Galaxy S4 and I am running low on space. When I checked my apps list it says I have 7 GB of apps, but when I used Memory Map, it says I am actually using 3 GB of space.

I've deleted caches and moved many data to my SD card, but there is little to no change. 

Is there a way to find and remove the 4 GB of phantom apps?
Basically every app will store some data. Hence it increases when number of applications get increased.

To get some free space, do the following: 


Press your device's Menu button &rarr; select Settings (or System Settings)
Tap Application Manager (or Apps)
Tap the app icon
Tap Clear Data\Cache.


Next thing is to disable\delete the application that you will not use.


6.Delete .thumbnails &amp; also unwanted files by making it show Hidden Files

7.Delete the Social Media Apps Folder Ex:/sdcard/whatsapp. But Before that, Select &amp; Move your Videos, Images, Files, Audios from Social Media Apps Folder.

Note: Clearing the app's data will remove any custom options, stored data and settings.
