Heya there. : )
I've got the same phone as you and I've been fiddling with it over the past couple of days. I also noticed when some people rang me, their Number's would come up, rather than their Names if they were in my contacts list.
I tested with my Mum's phone and her name came up when she called me. My name also came up when I called her. Now, our phones are pretty different Her's is a $79 phone, while mines $570. Big difference. So I don't think it's a phone compatibility issue.
I THINK the problem could be the following;
- - Whoever is calling you, might have THEIR number on private.
I used my mum's phone and hid her number. Turned the phone off and back on to make sure the settings worked. When I called my phone (the Secret) with hers, on my screen it displayed 'Unavailable' where the name/number should have been.
I changed her phone back to display her number and 'Mum' appeared on the Secret's screen, since I have her number in my Contacts list.
Unfortunately, you cannot do much with this, as it's up to the person calling you if they want to display their number or not.
- - A number is displayed on your phone you don't recognise, but it's a friend.
I'm taking a shot at this, but I figure, if you've got friend's ringing you, then they've Changed their number. So the number you have in your contact list is not the same as the one they're ringing from.
It's happened to me before, where I've thought I've had a friend's most recent number, but it turns out, she's changed it like, 40 times between the last time I called her a now.
If this hasn't helped, don't hesitated to contact me through the site, I'd still love to help you sort out how to get this phone to behave! : 3
