Wi-Fi is a staple among most smartphone users. While we tend to talk more about cellular data, it's really just there to sustain us as we travel from one access point to another. We aren't just demanding more data at higher speeds, we're connecting more devices than ever before. The inevitable overcrowding of the 2.4 GHz brought about the expansion into the 5 GHz range. Unfortunately, many Nexus devices (and at least a few others) are having trouble making and maintaining connections to this higher frequency band.
Man, Google. You just can't stop screwing with Christmas, can you? First you cancel December, and now this? In a very real and totally serious bug report over on Google Code, one user is reporting a serious flaw in Android: If you use the Emoji keyboard to enter a Santa face, he looks decidedly unhappy. Emotionless at best. But, as everyone knows, "Santa should be jolly."
Okay, yes, so Google did fix that Calendar problem, and even went out of its way to build a special Santa Tracker, after Norad hired that other search engine.
