I have an Android HTC One SV (Android 4.1.2, HTC Sense 5.0, not rooted). It's recently been struggling for storage space to the point where it was reporting low and then critically low storage. Note this is the app storage, not anything to do with the built-in or external SD cards.

tl;dr: Is there a known issue with "dead files" cluttering up App Storage? Is there any way to clear said storage out, or at least view the app storage and see what's taking up the space?


Steps I took as space became more and more scarce:

  • Moved apps that don't care about being on the App Storage to the SD Card
  • Cleared all the caches I could find
  • Cleared all the data I could find
  • Deleted all text messages
  • Moved apps that really don't like being on the SD Card to the SD card
  • Uninstalled all uninstallable apps except the ones I was actually using on a daily basis
  • Uninstalled updates to the non-uninstallable apps
  • Uninstalled apps that were actually on the SD Card out of sheer desperation

Whatever space was regained by this was in the 10-50 megabyte range in total and was "mysteriously eaten" over about 2 weeks of normal usage (e.g. web-surfing on Chrome, checking e-mails). By the time I'd got to the bottom step, the automated storage tool was informing me that there was nothing to uninstall/move.

When the phone finally started reporting "less than 0Mb" and crashing the basic phone functionality, I took extreme measures and "Power+Vol'Down'd" it, selecting "Clear Storage" from the BootLoader. That got me back almost 1Gb of space, at which point I was finally able to install Android 4.2.2 (up to this point, it couldn't even download the necessary update). I also updated all the built-in applications to current.

I then installed my core application suite:

  • Note Everything
  • BeyondPod Pro
  • NoteEverything Pro
  • Amazon MP3
  • Audible

My phone currently reports that it has 355MB of "App Storage" available; out of 3.85 Gb. Of the used, 673MB is Apps, and a staggering 2.85 Gb is the mysterious "Other".

I want that Other back. The space reclamation tool merely suggests I uninstall the 5 apps above for a grand total of 66.7 Mb, which is... irritating.

Is there a known issue with "dead files" cluttering up App Storage? Is there any way to clear said storage out, or at least view the app storage and see what's taking up the space?

  • A couple of quick thoughts based on your comments: -how much space are your amazon mp3s taking? -the audible books? -are you syncing a bunch of emails? some attachments can gobble up space -web downloads? did you flush the chrome cache too (not that that will get you much, but just thinking aloud...) – LivedWithOtters Feb 19 '15 at 22:06
  • @Lived: Effectively none to all of those (Haven't started the re-download process). But even then, the MP3's shouldn't be going to the app storage, surely? – deworde Feb 19 '15 at 23:35
  • @LivedWithOtters and yes, the Chrome cache and data were the first up against the wall. – deworde Feb 19 '15 at 23:43
  • Well, dang. Those were the easy ones. Don't suppose you're rooted? – LivedWithOtters Feb 20 '15 at 0:44
  • Nope, (see the parentheses at the top for my specs) – deworde Feb 20 '15 at 6:32

When I researched this same thing, all I came across pointed to that data being used for the HTC sense software along with other preinstalled apps.

  • Would that turn up as "other"? Being app-data, I'd expect it rather under "Apps". – Izzy May 28 '15 at 15:29

    Consider adding some reference links to the answer since we can't be sure what did you research on this same thing (and whether that supports the answer or not) – Andrew T. Jun 2 '15 at 0:57
