I was running 424 and applied the changes to bring it up 429, one of which was android 10.2.0.132 which effectively broke all my sideloaded android apps (instagram, amx, etc) and the taskmanager from BBW. I downgraded back to android 10.2.0.131 and everything works again.
I applied the changes to get OS 1803/ Radio 1804 as the reports I read stated that call quality was significantly improved. I can't report on that yet, but android was a bust...
