Hello, I put Samsung on the heater for about 10 minutes at a temperature of 85 degrees. Then I take a metal opener, so flexible and thin 0.1mm, and delicately insert it first on the sides of the frame, and then from below. Remember to slide it literally around 0.5mm on the feel, I did not measure. As from the bottom I get a small space between the frame and the glass from the bottom I use oca liquid separator. I cover the entire glass with packing tape to catch it with the suction cup for a moment. You must remember that the LCD wanders from time to time to the heater. I try to pour this liquid in very small amounts, preferably with a thin needle and a long precision syringe, into each created gap. Thanks to this, I am starting to have space under the display, I use plastic openers for the LCD approach, also flexible in the shape of a credit card. When inserting a plastic opener I always try to pour some separator oca. Gently taking the suction cup upwards, I slowly get the entire LCD out of the frame. If the cracks are at the top in the place of electronics I do not take the LCD up but I slide it down, thanks to which the glass electronics remain intact. If the top of the glass is ok, I open the whole LCD up. Of course, all activities should be performed sensitively, and the liquid only for amoleds.
