Based on the teardown the repairability of the OPPO F9 seems to be quite low. The use of strong adhesive for the back cover and battery as well as the need for alcohol to dissolve it 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 easily accessible battery cable and the use of pull tabs for battery removal are positive aspects. Overall I would give the OPPO F9 a score of 6.0 out of 10 for repairability.
