I have a Samsung Galaxy S4. I am getting the "Storage space running out" error message in my notifications bar, and some applications have quit working or updating. None of the usual solutions I've read about elsewhere on the site have helped me.

The most common solution to this problem is to access a hidden menu by dialing *#9900#. When I try this, however, the menu does not appear:

Another common solution is to root the phone and delete /data/logs. Looking at what's taking up so much space on my phone, it does seem likely to me that the problem is my phone has lots of accumulated log files that aren't being deleted. I would rather not root my phone, however. I am happy with the functionality my phone has, even with bloatware and tied to my provider, and I don't want to take the time to root my phone for this one problem if I don't have to. =P

Finally, a third option I've read is to delete apps that are taking up a lot of space. I've attached a few screenshots below showing how my phone is using up space, though, and I believe that they show that my real problem is that there's something my OS is doing wrong, perhaps creating a lot of log files and not deleting them to save space. (Besides that, I've already tried deleting some apps I don't use often. The overwhelming majority of my apps don't take up much space at all, and the biggest space-wasters are also the apps I use the most and the reasons I have a smartphone.)

Is there another way for me to get back more storage space without rooting my phone?


If necessary, I'm willing to plug my phone into my computer and use developer tools to resolve this issue.


Here are a couple images showing that the biggest gain I could get for storage would be to delete some system files (which is why I'm guessing that the problem is accumulated log files). I have over 6GB that my phone categorizes as "Miscellaneous files:"

And of the files my Android includes in that category, over 6GB are generic "System memory" (again, I'm guessing logs) that, unfortunately, I can't interact with or delete from this menu:

  • I tagged my question Galaxy S4 because I wonder if the problem might be specific to my phone. In particular, I know that the *#9900# trick only works on some phones, and I wonder if there's a different trick along the same lines for Galaxy S4s in particular. – Kevin Aug 18 '15 at 00:06
  • Also, is there a good way to resize my screenshots using Markdown? They're pretty big right now... – Kevin Aug 18 '15 at 00:06

    Resizing done. You may use m at the end of the imgur link to make it into a mobile image like https://i.stack.imgur.com/wJYhW.png -> https://i.stack.imgur.com/wJYhWm.png. Alternatively, you may use this [<img src="" width="210" height="350" alt="IMG: " title="">][] (e.g. [<img src="https://i.stack.imgur.com/wJYhW.png" width="210" height="350" alt="IMG: " title="">][1]) to display the resized ones much better. – Firelord Aug 18 '15 at 02:12
  • Is factory reset not an option for you? 2) If you're aware of the activity responsible for that hidden menu then you may use ADB to show that menu. I don't have any Samsung device in my possession so that's all I can offer as help.

  • Thanks for resizing the images! 1) If there's no other option besides factory resetting, I can do so, but I'd much rather not. 2) How would I do that? I've been thinking about seeing if there's a way of connecting my phone to my computer and seeing if that gives me any more options... – Kevin Aug 18 '15 at 19:53
  • +1 presenting it clearly and for the research done. Have you checked if #9090# Diagnostic configuration* also #0# for General Test mode – Manu Aug 19 '15 at 18:27
  • Thanks for the tip, @manubhargav. Unfortunately, #9090# and #0*# don't do anything on my phone, either. – Kevin Aug 19 '15 at 18:43

  • If you use, instagram try clearing the app cache in settings. It might free up some space. – Manu Aug 21 '15 at 09:35
  • Are you using Samsung Galaxy S4 I9500 or I9505 ? – Manu Aug 21 '15 at 09:42
  • @manubhargav How can I tell the difference between the two types of S4s? Also, I don't use Instagram. – Kevin Aug 21 '15 at 15:08
  • You can check the model number in settings>about phone. See if it's international version because some carrier specific phones (Verizon) has 6gb of bloatware – Manu Aug 22 '15 at 04:08
  • @manubhargav The "About Phone" menu doesn't show I9500 or I9505 in any of the fields for me. The model number is listed as SCH-I545. – Kevin Aug 22 '15 at 06:15

    It is Verizon carrier phone. Almost all of those network carrier phones have 6gigs of miscellaneous files which is unaccounted for – Manu Aug 22 '15 at 12:45
  • Is there an equivalent to dialing #9900# for tablets? – Al Lelopath Feb 16 '17 at 16:55

    @AlLelopath That would make an excellent new question! You're more likely to get help by asking a new question as well. – Kevin Feb 16 '17 at 18:24
  • Ok. thanks. Does #9900# apply only to Samsung devices? – Al Lelopath Feb 16 '17 at 18:30
