I just noticed something on my wifi only xoom and my wife's ..... On hers her wifi strength meter is blue and the same color as her battery meter icon on the lower right bottom of the screen , on mine the wifi strength meter is grey. We both have the wifi only model and they were purchased the same day one from Costco one from Staples. Also we both have our screens at the same brightness percentage using the same app. I also adjusted the brightness to check if it changed color at different levels and it stays grey even at 100 percent brightness. Is mine a bad unit? Does anyone else have the grey wifi strength meter? Thanks for the help and if anyone can check there's I would appreciate it.
