Will reset to factory defaults wipe updated OS

[JohnBoyCr]

I recently updated my Samsung J5, which came with Android 5.0 installed, to Android 6.0 (via my carrier). If, for some reason, I do a reset to factory defaults will that wipe out my update? I am guessing that the factory ROM was not overwritten with 6.0 so that probably it will return to 5.0. I can always do the upgrade again, if necessary, but would rather not have to do so. And I don't know why I would have to do a factory reset but want to know what happens, just in case.

You will keep the latest update.

Research FR carefully before doing it. If you need advice, just say.

Thanks, but I am afraid I don't know what FR means. And YES, I will be careful. Does it mean Factory Reset ?

Thanks, but I am afraid I don't know what FR means (maybe Factory Reset). And YES, I will be careful. Save personal info to SD and NOT erase during reset.

I'm sorry, it does mean that, but I thought that that was what you were talking about, except that you were using a sort of Windows term for it.
If you do mean Factory Reset, we have Ambassador Guides, which I might as well link right here:

God forbid that I would use a Windows term. Egads! Haven't used anything but Linux for years. Probably should have used the term "Factory data reset" as that's the way it is identified on the phone.

I once had a problem after an update of the APPS and my connections, when making a voice call, were really bad. I assumed that the update was bad so I did a "Factory data reset" and then phone started working again.

I hope not to have any reason to do the reset again but just wanted to be sure that I would not revert back to the previous OS if I did so.

Thanks for the feedback.
