How can you confirm the fix?
Test the same accessory with another phone and a different accessory with the Galaxy to isolate the fault.
When should you contact service?
If every accessory fails, arrange hardware diagnostics with Samsung support.
⚠ Stop using a device if it overheats, shows liquid damage, smells burnt or has a swollen battery.
Will a repair cost money?
Settings, cables and user checks may require no repair. Hardware costs depend on the exact model, warranty and service diagnosis; no fixed price is promised.
Quick answers
Could these checks affect warranty?
Use only external checks recommended for end users by the manufacturer. Opening batteries, electronics or sealed parts can create safety and warranty risks.
What if the steps do not help?
Write down your model, software version and test results. Share those details with official support rather than repeating potentially unsafe actions.
