A review and demonstration of this fine machine from YIHUA. It's the YIHUA 946A-III Digital LCD Screen Separator. An actual demo of me getting the back off my Android phone and battery starts at approximately 16 minutes 50 seconds.
I am guessing, but the only way they could make the phone water resistant ip67/8 is if they glue the case. Making the phone unfixable for the average person is just an added bonus. Thanks for the full demo!
