The most recent back up is driving me crazy. My biggest issues are text alert sounds and contacts. I no longer receive text alert sounds when I am in the conversation window. If I set down my phone I'm unaware that I receive a response unless I back out of the text app altogether after each text I send. I am also having issues with sending and receiving texts with iPhones. There doesn't seem to be delays when texting with individuals who have android devices, but if they have iPhones I experience delays up to 24hrs. I am also having problems with my contacts. ever since the most recent update, if I make a change to an existing contact it reverts back to a previous state. One day all of the images for my contacts disappeared. I reattached the images and then they disappeared again the next day. This has become consistent now. A friend got married and I have been changing her name for days, another got a new phone number, they just won't stick. There are other oddities, delivery alerts days after sending, alarm volume changing without me messing with it, battery all of a sudden has a shorter life, it's crazy. Help!!!
