Sorry this is tab 4s not a phone. It is my guess that it was rooted then it was restored back to the original load. The seller claims it was not rooted, but they were to quick to provide all the links of how to reinstall the original software from Samsung. Would there be a way to see the update or reload of software trying to remove the root? Sorry I am clueless about this rooting thing, Just wanted a tablet that worked.
Hardon, Thanks for the help, would the file explorer like Solid Explorer or Root Explorer show the reinstall date if they tried to "unRoot" the tablet? This is my guess as to what happened, it was rooted, then it went bad then the thought was restore it to the original and sell it. I am looking for some type of date before when I bought it.
