I just noticed my storage which is nearly full. So I went through Settings -->storage. Surprisingly, under the internal storage, system, usage shows 103GB. I have no clue how the system uses that much space. Please help.
Yes i agree with mbckl back up to your phone data to a lqptop vua smart things it takes 10 or 15 mins depending on the data you have and proceed with a system reset
You also need to note which applications you have so you can reinstall them, you will probably lose all your saved passwords, and my home screen had lost its icons, so keep a list of them. Worth it in my case as I had reached maximum storage. Try to create two backup locations (Googlr, Dropbox, etc). as sometimes your future backups overwrite old ones and you lose stuff
