A mysterious app named "10102" shows up in my data usage. It bears only the standard Android app icon (the Bugdroid logo with a cube on its torso). From what the graph tells me, it has used 36 megabytes of data in the background and zero on the foreground.

I think I haven't uninstalled anything for months.

Is it malware? I haven't sideloaded anything and only authorized my laptop as a USB debugger. If it's malware, how do I remove it? I have no idea how to find its package name and 10102 isn't in the list of downloaded apps in settings.

I'm running stock & never-been-rooted Android 4.4.4 on Nexus 4.

  • I'll let it sit for a few days. If it stops using data, it's probably some uninstalled app. Otherwise, it's most likely a malware. Either way, I'll get back to you guys and upvote and pick an accepted answer. – starleaf1 Nov 6 '14 at 0:57
  • I just realized that I am having this case too. In my case, it's 10120 with only background usage of 40 bytes. I also tested uninstalling an app, but it just removed the entry in "Data Usage". On the other hand, there is a "Removed apps" entry inside that page too, which I think uninstalled apps' data go into there. I'll monitor this issue for a while. – Andrew T. Nov 6 '14 at 2:07
  • Here's my list - 10926, 10266, 2021, 2030, 12161 and there are much more in my Data Usage. I usually install and uninstall apps all the time. May be these numbers belong to them. – MANI Nov 6 '14 at 6:00

    UIDs ranging between 10000 and 19999 are assigned randomly to installed apps (system and user). If you do a factory reset or reinstall a user app, the assigned UID will be changed. – Irfan Latif Feb 29 '20 at 14:07

It's probably an uninstalled app. It happened on my phone a few times.

  • Looks like this is a bug or something. – starleaf1 Nov 10 '14 at 6:15
