My phone just alerted me about the new system update. so i did it. and it ofcourse took like 20 mins, which was no prob. I was looking forward to an update. but now its all done and it erased ALL my numbers. like my numbers are there but theres no names to them. and also it keeps alerting me that i need to sign into youtube for some reason and it has my correct user name for youtube in it but it says my password is wrong and i need to re enter it. so i did that and its telling me im entering the wrong password but im not. and did it over and over 20 times and it keeps saying wrong password.
