Re: A testament to Google's expertise
I have the same problem - brand new Nexus 6P. Lightning quick out of the box, a month later it's started lagging, pausing and generally being slow. My HTC One M8 did the same thing.
Yeah, I know it's most likely down to some app I'm using and when I have the time, I'll put the work in to figure out which one it is. It kind of defeats the point of having a smartphone if you can't just install apps with impunity though.
