[Q] Freshly installed 4.3 produces ghost OTA update notifications
I have installed Android 4.3 from occam image downloaded from Google to my Google Nexus 4. The phone has been rooted and set up with TWCR.
The problem is that every week or so the phone thinks there is an OTA OS update from Google: a notification icon pops up telling that an "update to Android 4.3" has been downloaded (update size 1.8M). The update "installs" in a second, boots into TWCR which offer to repairs root access (and I do), and then boots normally. There is no that "optimizing app N of M" lengthy process as with a real OS upgrade.
I confirmed that the build incremental version in /system/build.prop does not change; in fact, the build fingerprint is not changed by this "update":
Why does this happen and what may I try to do to prevent this?
