I have never seen anyone talk about this before, but my problem lies within the recent apps screen. That problem is literally nothing showing up. I can have 1 to all of my apps "running" in the backround and -every once in awhile (this problem doesn't happen too frequently to where it is ruining the experience)- the apps won't show up. I can be in an app and press the recent apps button and see the app get smaller to fit inside the screen, then when it get to the right size *poof* gone. And it says there are no recent apps. If this problem happens, spamming the recent apps button until they show up works. It takes around 30 seconds of waiting then they all reappear. Not looking for a fix unless there is one, just sharing my experience.
