What issues are these? Weak or weird GPS signals. Random restarts. And phantom multi-touches.
I've only experience the touch issues. However, I've experience other issues that seems innate to Android as far as I know. Random freezes with touch, swiping, or typing. A couple of times, I've had to restart, on purpose, to get back the responsiveness. And I'm not running many apps. Even with a couple of apps, this could happen. Feedly, Groupme, Twitch, and Flipboard are the most commonly used apps for me.
And I also take care to kill them whenever I know I won't be access a particular app for a while.
Like the article mentioned, there was an update from Google last week. I saw no effects from it. In fact, I'm not going to worry or think about this further unless it gets progressively worse. I hope Android 5 will fix all if not most of the issues. I think that's where Google is concentrating on and that is where I want its attention now.
