For any future people repairing their tablets. DO NOT REMOVE THE SCREEN. I thought my tablet was a Tab 2, but no it was a Tab 3. No heat guns needed. I ended up cracking my screen a bit. I don’t know the extent of the damage yet, but Im probably going to get a replacement screen. You need to pop out the whole thing. Not just the front screen. The reason being that there’s a sort of metal scaffolding holding the screen and the back together. This needs to be separated to put in the new charging port.
