Based on the teardown the repairability of the Samsung Galaxy F-15 5G appears to be relatively high. The back plate can be easily removed with the use of heat and a pry tool and the SIM tray does not have any rubber gaskets that could complicate the process. The plastic back plate and glass camera lens covers can also be easily replaced without having to take apart the phone. The Flex cable for the fingerprint scanner is easily disconnected and there are only 15 screws that need to be removed to access the internal components. However there are some challenges in repairing the device. The adhesive used to secure the back plate may be difficult to remove without overheating the internal components. The battery is also held in place with adhesive which may make it challenging to replace. Additionally the screen can only be replaced by removing the back plate and disconnecting the flex cable which may be time-consuming. Overall I would give the Samsung Galaxy F-15 5G a score of 8.25 out of 10 for repairability. While some components may be challenging to replace the majority of the device can be easily disassembled and repaired.
