Adhesive is between the back cover and the battery, between the other side of the battery and the internals and between the bezel that hides the screw. The bezel is very fragile and I broke and scratched mine even though I was *very* careful. Bye bye resale value.
The absolute worst thing is, the motherboard is glued to the display assembly! The mobo is VERY thin, and trying to pry the board off the display assembly is, IMHO, very likely to damage the board. I have done a lot of these repairs, and this phone sucks for serviceability.
The battery is easy enough to replace, but pay a bonafide service to replace your screen. If they screw up the phone, then they are on the hook to buy a new one, not you....
