Oky i got a cingular, samsung phone. and outta nowhere it starts acting funny like i cant hear the ringing of the phone. unless its on speaker and i cant talk to the person unless its on speaker. but i can still hear like my ringtones and stuff. how can i fix that without buying a new one?

Your phone is covered under a warranty. What I would do is call cingular and have them troubleshoot the phone and it will most likely need to be replace through a warranty exchange. What you can try is taking out the battery and leaving it out for about a minute. When you put the battery back in and turn it on see if the speaker is working again. If not look inyour manual for a master reset and try that. These are things they are going to have you try when they troubleshoot it. Most of the time a master reset works.
