Launching apps and backing out of them with the back button seems faster. Loading the multitasking menu is faster. I have the official version of Google Wallet (using the web market trick) and I was able to update it through the market on the phone with no issues. Works as flawlessly as ever. Landscape keyboard in Chrome at least is a bit faster and the portrait keyboard feels faster. Automatic brightness transitions from dark to bright are smoother, although it is still too aggressive on keeping the screen darker in seemingly brighter light. Volumes seem the same. Sounds aren't louder than the settings I had previously. When you hold down the power button, you can now select three volume level settings (besides airplane mode and power off): sound, vibrate, and full on silent. Nice. Camera app updated. It performs better and the settings icon has been changed to make it more obvious, but image quality remains the same at least indoors. Bit disappointed but there's only so much they can do.
