I would advise against using a metal spudger to remove the battery itself. While working at a device repair chain in the past, a coworker of mine punctured a battery with a metal spudger and destroyed the phone. Instead, use a sturdy plastic spudger to remove the battery. Otherwise, great guide!
I got the battery fixed but shattered my screen wish it was more informative on how to get out the screen
Would using the Anti-clamp with heat gun be better option?
There is a YT video where a famed smartphone repairer makes it look easy but in the comments people are saying they broke their screen. The videographer doesn’t reply to comments.
The guy uses a plastic (I think) business card to lift the screen, sliding it under at the bottom and gradually pulling the protruding sides of the card all the way to the top. I don’t have one so I bought a plastic yogurt carton. I am not sure how well its plastic will withstand heat. A source of heatproof plastic, or nylon card please?
How hot can I heat the screen? I have a non contact thermometer.
I also wonder whether the same glue will work. It doesn’t need to be waterproof.
I think I am going to destroy my phone. I wish there were rugged phone with changeable batteries. I love my S6 active but it is start to not run apps eg LINE.
