Storage issue on LG Magna

[AC Question]

Hi there,

I am using LG Magna since last year... I am facing storage issue from past few months. Have already moved the apps from internal storage to SD card but still internal storage is full. SD card is of 8 GB and still 5 GB space is there.. Please suggest if there is any way to increase the internal storage or any other way to overcome of this problem. I have not updated my apps since long and able to install new apps too.. Please suggest something..
Thank u
