Open state. There seems to be no "cable trap" that could break if opening the back panel. However, adhesives stretched around the periphery are troublesome to raise the degree of decomposition difficulty.


It is like pushing the fingerprint sensor from the bottom. IFixit says that a fingerprint sensor at the location of the index finger will be mistaken for a camera if it is a right-hand operation.


It is still unknown whether a locking system for safety such as iPhone 7 is installed. Whether it is possible to replace the fingerprint sensor seems to be greatly related to the difficulty of repairing the smartphone.

The decomposition and repair difficulty score of Galaxy S8 by iFixit is "4" ("1" is the most difficult in 10 grades evaluation). As a point that is easy to repair, many components are modular and easy to replace, but as an element that is difficult, it is essential to remove the rear panel to replace the battery, so that it is very powerful for the rear panel and glass on the display surface Because adhesive is used, it is easy to break during disassembling, curved display glass is very difficult to break down without breaking.
