Motorola Q power button

push green button and hold on for a couple of seconds.

Remove the battery and hold down the power button for at least 30 seconds. This will reset the circuits. Put the battery back in and turn the phone back on. If it still hangs and doesn't load you may have a corrupt boot file. In this case you'll want to contact Motorola. Good luck!

go to cellphone center for repair

no you cant calibrate it

Mine does the same thing..
razr's just blow

take the phone and have it check

just close the phone. depending on what model you have it will usually just end the call.

Some phones answer when picked up off the charger, but with some you must press the talk button to answer. Some have a green reciever on the button. And to hang up you must press the off button or the button with the red reciever.

I don't know but mine's doing the exact same thing. Mine also keeps the screen on almost all the time, sometimes it turns itself on and back off and back on for hours. Once every button EXCEPT the red button worked... and once only the top left button worked, so i could answer calls but couldn't hang up. My friends enjoyed messing with me for that one.

I have had this problem on my V3 also, turns out that the flex cable tends to get cold solder joints, find someone at one of your local mom and pop cell phone stores. Can usually find parts on ebay. Am not sure exactly which cable it is, had local tech that discovered he could solder the connections on the cable. http://search.ebay.com/search/search.dll?from=R40&_trksid=m37&satitle=v3+flex+cable&category0=
