Title	Huawei P20 Home Button with Fingerprint Sensor Replacement
Introduction	Use this guide to replace a defective home button with fingerprint sensor in your Huawei P20. Opening the Huawei P20 will '''damage the splash and dust protection seals''' on the device. If you do not replace the adhesive seals, your phone will function normally but will '''lose its protection'''. Due to the phone’s design, we recommend removing the lithium-ion battery in order to remove the screen and have better access to the components. However, it is possible to remove the screen without removing the battery. '''Reusing a deformed battery after it has forcefully been removed, is a potential safety hazard. In this case, replace it with a new battery.''' '''Before disassembling your phone, discharge the battery below 25%'''. The battery can catch fire and/or explode if accidentally punctured, but the chances of that happening are much lower if discharged. You’ll need '''replacement adhesive''' to reattach components when reassembling the device.

Conclusion	If possible, turn on your phone and '''test your repair''' before installing new adhesive and resealing the phone. To reassemble your device, follow these instructions in reverse order. The best way to secure the new screen is with a sheet of [guide|113604|custom-cut double-sided tape]. Apply the tape to the back of the screen, then carefully feed the display cable through the frame. Align the screen and press it into place. Take your e-waste to an [[E-Waste|R2 or e-Stewards certified recycler]]. Repair didn’t go as planned?
