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 tell 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 a malware? I haven't sideloaded anything and only authorized my laptop as USB debugger. If it's a 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.
