after updating my phone to lollipop my calling and texting will not work. I have tried everything including updating my profile and resetting my phone. I have called Sprint and went to the store but all they kept saying is that they do not know. is there anyone that can help me ? when ever i try to make a call it say mobile network not available but my internet and 4g works just fine. is there anyway to uninstall lollipop? or would rooting help?
