I have a Micromax Unite 2 Android phone.
The original internal memory was 8 GB, but now it shows me only 1.67 GB.
I used a third party app to see what happened.
It shows me unallocated space in 4 different partitions, each one is 700 MB. Other partitions are system, userdata, cache etc.
Currently my phone has Android 4.4.2 KitKat.
Is there any command to do that from terminal? How to allocate that space? Please help me.
