| Screen Goes Blank While Making a Call The screen on my 680 has recently started going blank, as if the power is off, while I am making a call. Oftentimes, the call drops before its picked up by the party I am calling. I notice it more frequently when using the headset that came with the unit but it sometimes happens when I am not using the headset.
The only "nonstandard software" on the unit is minitones, but I haven't had the occasion to use it.
I did a search of the forum before posting this message but nothing came up. Any ideas what may be causing the problem? |
