Yesterday I completed replacing the loudspeaker for my note 9 using the instructions in this guide.
Although I had to reheat the i opener a few times I found it very useful to use a thermometer to check on the build up of heat in the phone.
Once I got the back off it was just a matter of following the instructions step by step.
I think the instructions are excellent!
Thank you!
