Same complaint. The voice command screen will come on three times during a text. It is annoying to the point that it overshadows most of the great aspects of the phone.
My lumia900 screen buttons start typing on its own when am charging and making use of it...... And often restarts on its own when i switch it on, especially when my sim is inserted
Under Settings --> 'display+touch' ..set the touch sensitivity to LOW and see if that makes any difference. For the rebooting problem, you may have to confirm whether the problem is related to SIM by trying another one ( borrowed from someone) or getting yours replaced ...

I am under settings and do not see display-touch??
I wonder whether farby referring to Windows Phone 8 device such as Lumia 920 here where this is an option, although not present upon Windows Phone 7.5 such as Lumia 900.
