Experiencing some bugs on moto g 1st gen with lollipop. Sometimes the screen wouldn't respond to touch and have to wait till the battery runs out. The dictionary feature oof KitKat was better. The stock home screen looks almost same as KitKat and doesn't feel as good as moto x 2nd gen lollipop. Not so happy about this.
If you could turn the screen on/off using the power button, then you could restart the mobile by long pressing the power button (10-15 seconds)
