The problem is that the phone will not ring for either incoming or outgoing calls. Someone phoning me gets no rings, it goes immediately to voice mail. When i try to call out the screen looks perfectly normal - all of the correct icons are showing up so it looks like it is ringing, but it is not ringing either at my phone or at the person i am calling.
The problem is cured by restarting the phone. Only after i restart the phone do i get notification about any messages that were left.
This happens only when the battery is at about 40%, but not always - just occasionally and rarely. It happened today for the first time in a few months; it also happened a few times, a few months ago.
I would think that at 40% battery there should be no battery charge related problems? 40% should be plenty to run the phone?
Any ideas? I am going to return it to the store and ask about this, but i would like to have some more info to go on, if any is available.
