It was taken oct 26, now its Nov 5 (I checked for the latest security patch, there is still no patch). I left google a feedback on it right after I saw it happen. Also at the time, I hadn't uninstalled any updates from the default apps. Whatever the problem is regarding this monthly security patch, it's pretty bad and I'm wondering if anyone has problems doing this.
Edit: Also it's the same with the quickstep launcher that comes with the phone.
