Based on the teardown the repairability of the device seems to be average. While some components can be easily replaced such as the camera lens cover and the back plate others require more steps and tools to access and replace. The use of adhesive also adds to the difficulty of repairs. Overall I would give the device a score of 6.5 out of 10 for repairability.
