It works fine for me since I have decent sized hands. But if you don't like it you can install a Rom with volume button wake or a kernel with s2w
Currently with screen lock disabled, coming from S3 running sammy based rom and aosp 4.2.1 need lots of adjustment to come over to sense, it shows how far HTC ran off from Google's intended interface.
wait, what is only 1.5 gigs?
User land RAM, which is about 1.7~1.8Gb on Nexus 4 and Note 2
That's how all phones work... When you use the phone the battery goes down. And the processor gets warm when it is used.
Yes, that's how phone works. Let me explain, 5inch 1080p vibrant screen - check, powerful 1.5Ghz S4 pro - check, feature rich Sense 4+ - check, All those powered by a measly 2020mAh tiny battery that even Xperia Z is packing over 2300mAh for similar speced device.
While S4 pro is powerful, but that's only when it's not throttled, which in my tropical country the normal operating temperature for my Butterfly is around 33C~40C. From benchmark and some heavy 3D gaming to maintain non throttled performance, pretty hard, basically on par with a9 based exynos4 processors in S3 most of the time in practical use.
If you can't accept these flaws, which they present in Butterfly and DNA, I never encountered on my previous S3 if it wasn't being snatch by some God forsaken bastards.
