Use this guide to replace a defective or cracked OLED screen and digitizer 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 with caution, or take it to a professional if you're not sure how to proceed.

You’ll need '''adhesive glue''' to reattach components when reassembling the device.
