Does anybody know where the internal antenna is located on this phone
(which side/end)? Most phones with internal antennas recommend that
you do not place your hand over the internal antenna while making a
call for best reception performance, except I don't know which area to
avoid? Any advice would be appreciated.

Maybe I will find out next week when I get mine in the mail and it
might have the sticker on it that says "don't touch here, internal
antenna," but I think only Samsung still uses that warning?
