I've had 4.2 running since the beta dropped. Over the past week or ten days, it got really laggy. I wiped cache and Dalvik cache, downclocked, even switched kernels. Nothing helped really, so I backed everything up and did a fresh wipe & flash...now it's rocking the way I remember, and with the stock kernel. So my question is why?? What else gets clogged up enough under everyday use to cause these symptoms? By this point, I had flashed a couple different themes, downloaded a number of new apps, uninstalled a few...can somebody here explain what might happen to slow the old girl down? -from my P.E.-flavored Droid.
