I recently replaced the back of my lg g6, and after about a week, the back has started to go farther away from my phone. I used 2 layers of 3m 3mm adhesive tape, and it was on very firmly at first. What did i do wrong? How can I prevent this from happening

Try using b-7000 glue instead. It’s like a rubber type glue and easy to remove. Just make sure you don’t get it near cameras or speakers
