I've had my nook hd since January, and within the past month or so the performance has been very sluggish. For example, when returning to the home screen, it often takes about a minute to completely load the icons. After the screen loads, I can't tap on any icons. Also, When scrolling through the home screen, app icons, or opening web browsers, the screen display is lagging behind. Any suggestions? The only remedy I've found is restarting, but even this is only temporary for the problem usually begins the next time I use it.
It could be an app running in the background or at start up. What apps do you have running when this happens?
