all motorola phones i have used had this feature of backlight coming on with a new cell broadcast message.this sometimes may be annoying as well as a battery drain.i find it useful during train journeys,to keep posted on the place names.(in any monochrome set,this is easy).you can escape from this by deactivating cell broadcast.
I have a new slvr from US cellular. The backlight comes on every few minutes and the salesman at the store told me this in normal with all Motorola phones . Is this true??
