For the most part, I love my Galaxy Nexus. However, it seems to sometimes get laggy. Scrolling through the app menus can be a bit choppy, and apps can take a few seconds to close. Judging from reviews, it seems most people are having a flawless experience, so does anyone have any suggestions for speeding up my Nexus? (I did briefly unlock the bootloader and root before unrooting and re-locking the bootloader, could that be a factor?)
