Based on the teardown the repairability of the OPPO K12x seems to be quite low. The use of adhesive for the back cover and battery makes it difficult to open and access internal components. Additionally the need to disassemble multiple components and remove the mid frame to replace the screen adds to the complexity of repairs. However the battery cable and pull tabs for the battery do make it slightly easier to replace. Overall I would give the device a score of 6.0 out of 10 for repairability.
