I just got brand new phone from ATT, while charging I noticed the screen stayed on.
Am I missing something or is this a Android Bug? Usually Developer option is hidden in a new phone. But on my phone the developer option was on and screen set to stay on while charging

So when charged overnight my screen stayed on for several hours. Is this a bug or my phone was not 100% new?? Did it damage my screen? At least it was dimmed because it was dark...
Did someone had a similar experience on a brand new phone or did ATT sold me a refurbished one?
