Introduction
Use this guide to remove and replace the home button including the fingerprint sensor in the Huawei P20 Pro.
'''Note''': This guide instructs you to replace only the display while leaving the original frame and motherboard in place. However, some replacement screens for this phone come pre-installed in a new frame (a.k.a. chassis), which requires a very different procedure—transplanting all your phone's internals. Make sure you have the correct part before starting this guide.
Opening the Huawei P20 Pro will '''damage the waterproof seals''' on the device. If you do not replace the adhesive seals, your phone will '''function normally''', but will '''lose its water protection'''.
Do not reuse the battery after it has been removed, as doing so is a potential safety hazard. Replace it with a new battery.[br]
Before disassembling your phone, '''discharge the battery below 25%'''. [[What to do with a swollen battery|If your battery is swollen]], do not heat your phone. Swollen batteries can be very dangerous, so wear eye protection and exercise due caution, or take it to a professional if you're not sure how to proceed.
You’ll need replacement adhesive to reattach components when reassembling the device.
Conclusion
The best way to re-apply the screen is with a sheet of custom-cut double-sided tape. Remove any old ahesive and apply the new tape to the back of the screen, then carefully feed the display cable through the frame. Align the screen and press it into place.
To reassemble your device, follow these instructions in reverse order.
'''If possible''', turn on your phone and '''test your repair''' before installing new adhesive and resealing the phone.
Take your e-waste to an [[E-Waste|R2 or e-Stewards certified recycler|new_window=true]].
