Which phone model do you have?
I'm most definitely NOT a VZW employee. If a post answered your question, please mark it as the answer.
We can understand wanting to customize your device to look the way you want based on your own personal settings. It is concerning to hear that this is no longer the case with your phone, but we are here to help. Was there anything that happened before the colors changed from what you had previously set? Ann154 is correct in that we would want to know what type of phone you have so that we can walk you through checking your settings.
