Review on Unlock Your Device With Showpin 3-In-1 Smart Phone Repair Tool by Lenny Sullivan

I used this tool to open my Galaxy S9 phone to change the battery. I did not use the phone holder since it got in the way. I used by wife's hair drier to heat the edges of the phone to soften the glue. I heated around, keeping moving the drier constantly while applying open force with the tool until the back surface reached about 120 to 125 deg F as measured by my digital fever thermometer set to measure surface instead of body. As shown by many You Tube videos, when the bottom of the back started to separate, I rotated the tool around to the side to get a guitar pick into the separation. As I added more picks and the back cooled I reheated with the drier. I was surprised how easily the back separated.I would highly recommend using this tool.
