I am sick and tired of deleting duplicate entries in contacts and calendar. There is no rhyme or reason. I get some contacts duplicated numerous times. I get duplicate appointments and my new ones refuse to link to the PC. I have tried everthing that two weeks of constant googling can come up with. I am sooooooo GD sorry that I purchased this POS phone and from my point of view the Android system is also a POS. Next time I am going to finally bite the bullet and get an iPhone. If anyone has something new please let me know what to do. I have deleted ALL contacts in Google. I have deleted ALL duplicate contacts at least a dozen times. The stupid system still adds, at random, duplicate contacts and tasks. The stupid phone has even linked contacts with no reason or input from me. The calendar has put holidays in numerous dates. Columbus day was in the calendar seven times when I did the last cleanup (I have done 3 seperate cleanups today alone). Independence day was put on both July 4th and 5th. When I deleted it from the 5th it disappeared altogether. I thought my old Palm Treo was bad. It was light years ahead of this phone and the STUPID ANDROID SYSTEM.
