I'm having a semi-regular problem with my E90, I never have ringtones...they just annoy me so I always have my phone set to vibrate.
Problem is my E90 recently seems to have stopped working, although it does start again for no reason sometimes.
Has anyone else had this issue?
I have had this problem occasionally...
What's annoying is that you don't know the problem's occurred until you find out that you've missed a call.
I'm hoping that the new firmware fixes this problem; there's obviously nothing wrong with the hardware, as it is usually fixed by a reboot, so I imagine it's a firmware issue. Time will tell!
E90 does not vibrate when it is connected to the transformer or to the USB cable and in some other situations...
The problems you report doesn't have a pattern? Something repeated?
Did you ask Nokia when E90 is set to not vibrate?
