Why do I keep getting "not enough storage space"
Your phone has 8GB internal memory this is low if you have many apps installed, including updated apps.


If you turn on automatic update in google play, turn it off.
If it was already updated some Microsoft apps, uninstall them. This will return some space.
Facebook app is the big app. You can use Facebook lite or browsers instead.
Clear cache. Setting -> Storage/Usage -> click on cache and clear cache.
If you have Line or other chat apps, delete chat history one by one.


Hope this help.
