Based on the teardown the repairability of the Samsung Galaxy Z Flip 4 seems to be quite low. The use of adhesive for the back cover and battery makes it difficult to access and replace these components. Additionally the need to disassemble multiple components to replace the screen and the tricky process of replacing the foldable screen are also negative factors. However the presence of pull tabs for removing the battery and the easy accessibility of the battery cable are positive aspects. Overall I would give the device a score of 6.0 out of 10 for repairability.
