The Galaxy J6 earns a 4 out of 10 on our repairability scale (10 is the easiest to repair):

The only screws used are standard Phillips screws (granted, there are almost too many).

Display repair is prioritized, since it is the first part out—but at the cost of probably damaging it, making repairs to other components risky.

The battery is buried beneath the motherboard and adhered to the midframe, hindering its replacement.

The high-wear USB port is soldered to the motherboard, requiring a high level of skills and equipment for this all-too-common repair.
