Okay, so I consider myself a seasoned android user. But I have been stricken by a Smart Switch issue.
To date. I have used Smart switch to transfer from and to the following:

From S6 to S7 ( NEW )
From S7 to S8 ( NEW )
From S5 Active to S7 ( NEW )
iPad to Tab3 ( Already in use with Data )

In EACH case above. I have successfully completed the transfer over Smart Switch using an OTG cable.
And shortly after the phone restarts and does a factory reset. But it's a factory reset that would be done from the Android System menu which requires the last gmail account and password to be entered.
Which wasn't an issue as it was known.
But STILL what the HECK is going on? Why is this happening.
I have googled it thinking others would have the same issue, but notta

Thank You!!!

I didn't find the right solution from the Internet.
