So I have SS 5.4 with the bold and black theme on my D1 and running Go Launcher. When I first put the rom on the phone it was blazing fast. Now though after a few months/days of use without swapping to an updated version (not that i necessarily need an update) It has slowed down immensly. The lag between opening up an app from the home screen just seems to take longer than it should. Just wondering if there were any tips like clearing some cache or something to bring it back up to when I first installed. Also a thing that worried me was when I did a reboot to see if that would help that also took a long time. It also had to go through the animation twice. Kind of worried me because my nandroid that i have is backed up from 5/31 when 5.4 was released. But I redid a new nandroid just in case and backed up everything on TiBu. Not too big a problem just wondering if that was normal and if there was any small things to do to keep it from slowing dying.
