    This is the first decent software ever made for the Z1… Wifi range has doubled. The touchscreen choppiness issue has been completely resolved (I can finally type with SwiftKey Flow again!). There are a few minor tweaks that I liked a lot… But basically, wifi and touchscreen fixes have turned my phone from overpriced PoS to a true premium phone as it was meant to be… There is only one small issue where the screen takes about 3 seconds to wake up when taking the phone away from my head during a call, so I have to wait 3 seconds after saying bye to whoever I was on the phone with before I can actually press the end call button… Other than that though, I am really happy with this update. All I’m missing now is root access!
