I've done over 7 whitestone installations for various friends/family S7 edge, S8/S8+, and Note 8s. I've only really messed up the very first installation and the Note8 install is different than the S7/S8 one. The only tip I can give is to follow the directions and once you are on the first curing, ONLY cure it for the stated time of 15 seconds. If you go over the time you end up hardening the adhesive too much so when you start the first wiping process the adhesive will already start balling up from extra adhesive on the edges and pulling adhesive from under the edges of the glass. After the first 15 second curing, I always wipe the edges excessively with alcohol pads/cloth, like REALLY excessively. Wipe the sides gently like there is no tomorrow. You want to be absolutely sure there is no extra adhesive on the sides. Remember, the reason for this is after you start curing it again the adhesive hardens more and if you have any excessive glue still on the sides, when you wipe it will ball up and possibly pull out some of the adhesive from under the edges causing the bubbles under the edges you see in a lot of pictures.
