Based on the teardown the repairability of the Samsung Galaxy C7 Pro seems to be quite low. The fact that several components need to be disassembled to access the battery and the use of adhesive for the battery are major obstacles for repair. Additionally the delicate process of removing the screen and the soldered charging port make it difficult to replace these components. Overall I would give the device a score of 2.5 out of 10 for repairability.
