"Upgrading apps" message during boot I bought a new MOTO GEN2 2015, showing notification with Android upgrading start Apps.. while switching on the mobile, is any one facing this?
No, this isn't an issue.  Some devices running Lollipop seem to show this message very briefly for no real reason.  I would assume that it is checking that AOT compilation has been done for apps you've installed, but I don't really know.  In any case, it's normal.
