Well, there are various ways.
Your provider should have transferred your contacts to your new Q from your old phone and the easiest way I've found is to press the key of the first or last name of your contact. Let's say you want to call "Mike". Press M and any contact with M in the first or last name will be listed with M highlighted. Too many...so.... now press I (you have MI now) which narrows it further to any name with Mi (Mike, Minna, Michelle, Miller). If you still want to narrow it down because you don't see it, add K (you now have Mik) and that, most likely, should do it. If you have numerous "Mikes" or several numbers for the Mike you're looking for, scroll down until you find the one you want.
Uh, Oh... scroll.... a new word... here's how: Dead center on your phone is a rectangular thing (my word). It has 4 arrows - look very closely and you'll see them. Yep, you guessed it.. scroll up, scroll, down and when you need to scroll right and scroll left.
So...the name you want to call is highlighted because you scrolled to it and now all you do is press the key on the far left in the middle that has the green circle on it and, like magic, you're making a call.
Oops, you want to stop quick, the dog is barking... press the key directly opposite the one with the green circle that you just pressed that has the red circle.
So....I know I said there are other ways. Yep.. another way is to press the home key (the one that is to the lower right of the one with the green circle) with the little house on it and you will see on your screen the word contacts. Press the dot below it and you'll see a list and then simply scroll down to find the person you want to call and follow the steps above.
