Lack of storage space on my Galaxy s7

[Android Central Question]

I have been trying to free up some space on my 32GB samsung galaxy s7( I am having to use the optimize your phone a couple of times a week just to keep my phone from telling me it is out of storage) but after deleting all my videos, most my pictures and several apps, I have only managed to get 2GB of free space. When I look at my storage, the documents, images, audio, videos and apps only total to about 13GB. Is the OS really taking up that much space? Do I need to do a reset to get that space back?

What happens when you tap that System box?

 

[Sjames33]

Nothing. I can't seem to find anything in the app that will tell me what exactly is using that space

Try wiping the cache partition, which won't affect any personal data: https://support.t-mobile.com/docs/DOC-28028

Still says 17.8GB system data

Try dumping your logfiles: https://www.phonetipsandtricks.com/...-error-when-running-low-on-phone-storage-132/

I believe that the system data takes up 7-9GB of space by default on the S7, depending on your software version and device model (i.e. carrier-specific vs. unlocked). That 17.8GiB figure is definitely high, unless I'm forgetting something.

B. Diddy has your back.

@Patrick Schroedl, the prodigal son returns!

Thanks for all your help. Unfortunately that only dropped the system data to 17.7GB.

 

[B. Diddy]

Hmm. It's hard to say why the system data is taking up that much. Factory reset might be your next option.

Did the reset and now have 13gb of free space. Thanks for the help.
