I have a Moto E 2nd Gen running Android 6.0. In the Storage & USB menu it shows that I have used up over 4 GB of space, but it shows I have used only 2.5 GB for apps and around 100 MB of other data.
What is causing the discrepancy? Even clearing the cache does not help.
I tried DiskUsage. This is ascreenshot of my internal storage.
It shows System Data as almost 4GB. Is this normal ?
