Teardown of P20 Pro seems to indicate that all three cameras carry OIS

The Huawei P20 Pro has a unique triple camera setup on back. There is the main 40MP RGB camera, a 20MP monochrome camera and an 8MP telephoto camera. After the phone was dissected by iFixit, the latter states that all three snappers appear to feature optical image stabilization (OIS). For those who are not familiar with this, OIS prevents your videos from looking like you overdosed on coffee, even if you went on a caffeine bender before recording.

Officially, Huawei will only admit that the 8MP camera is equipped with OIS. The manufacturer says that the other two sensors rely on the AI based Neural Processing Unit (NPU) for what it advertises on its website as AI Image Stabilization. But iFixit says that based on its tear-down, it has discovered hardware that would indicate that all three cameras have OIS capabilities (the floating lenses are a solid clue). By the way, to get off the subject just a tad, the NPU can handle things like predictive focus, add different filters like bokeh, and automatically set the camera for 19 different scenes.

Because replacing the screen means going through two layers of adhesive, iFixit gave the Huawei P20 Pro a 4/10 for repairability. Other issues mentioned in the tear down include the glass front and back creating a double hazard and the difficulty in removing the battery (although it can be done). On the positive side, many of the components used in the phone are modular and can be replaced independently.
