The Huawei Mate 20 Pro earns a 4 out of 10 on our repairability scale (10 is the easiest to repair):

Many components are modular and can be replaced independently.

Battery replacement requires removing only the back panel and midframe.

Only standard Phillips screws are used along with an average amount of adhesive.

Because of the sandwich build around the motherboard, there are more flex connectors than average and repairs will consume more time.

Glued-down front and back glass means greater risk of breakage while making repairs difficult to start.

Screen repairs require a lot of disassembly while battling tough adhesive.

A broken screen probably means you need to replace the fingerprint reader as well, or vice versa.
