[H] I need a Android phone guru

[Winterlight]

I have a second phone = MotoG2.  A functional phone but very little 
storage =5GB. At some point I put a Micro SD Samsung 64GB EVO Select 
in it  and transferred as many apps as it would let me to the SD card 
which wasn't very much ..only 381 megs. What I should of done is 
install the card as Internal. I would like to do that now. What I 
would like to do is backup the phone, remove the card and clear it 
... then put it back in as Internal storage. So how do you backup 
everything on the phone ( about 5GB) so I can restore it exactly as 
it is.. only with the SD card recognized as internal storage. Thanks.
