“You need to buy this special heater pad to break the screen adhesive!”
No, I think you will find that in fact I don’t.
Seeing as you can do the exact same thing with a hairdryer, it’s inventing a solution to a problem that doesn’t exist.
The heated bed is coupled to a thermistor. I’d argue controlling the temperature in order to not accidentally overheat parts of the phone is a step above a hair dryer.
Also bad is that hair dryers don’t spread their heat around very well at all. You can easily create hotspots on the object and damage things with them.
