It seems like anyone with a rooted phone might get an error, but it still installs fine. First impressions is actually really good. The phone feels a little faster. The videos are smoother and so is the gallery. When I opened maps it found my location instantly instead of getting the %waiting for location" message. Accuracy was 1000 meters, but I didn't turn on the GPS.
Also the signal strength and internet speed seems much faster. And stronger for me
