Introduction
The OnePlus 6 smartphone might need a speaker replacement for several reasons, like water damage or wear from regular use. The internal speaker plays sound out loud when no external audio output is present. If the device will not play sound or sounds come out distorted, a speaker replacement may be required.
As this guide will help everyday users replace a part within the device, they should be aware of potential damage from using the heat gun. While working on the inside of the mobile phone, users should be careful not to damage any delicate parts.

If you have a glass back cover, be careful not to pull too much or it may crack. It's better if you keep heating the area before trying to get in with the opening picks, specially around the corners.

I was using a hairdryer on 2/3 heat level and my phone was very hot to the touch and it still wouldn't budge a millimeter to get the plastic tools in. Any advice? I'm not sure heating it more is safe for the rest of the phone, so I'm not sure what else to do.
