MotoBlur I already know from the Motorola Milestone XT720. Even then, the software was anything but fast. Meanwhile, the software has been purified and performance moderately improved. Trotztdem you reflected negative impact on the speed of the device. Really disable it can not be. For an incredible number of services continue running despite "off" in the background. In addition, the entire software tinkers based on Android 2.1 around aka "Eclair". Despite everything, we get about 1000Punkte in "Quadrant" benchmark. That's very good for a 2.1 Android device. 1200-1400 points are likely to be a problem with 2.2 then really. The question is, is 2.2? Motorola has to publish the character very late updates or to drop updates. The XT720 was less than six months on the market and it was announced that it does not get any update to 2.2. At this time was 2.2 probably already published notices about half a year! Seis drum 2.2 is to appear for the Defy in Q2 2011. Prefer a 2.2 update and play yourself? Ätsch: In Gegegnsatz to HTC Motorola closes his phone against any "foreign Firmware". Why? The only know the Lord God.
This is how well the phone reads the data sheet, the software policy at Motorola is really under all.
I can therefore only such mobile phones people recommend that this circumstance does not really matter or dare various instructions of the XDA-Developer to study ...
