Frequently Asked Questions

Does this main flex fit the standard Samsung Galaxy A20?
No. The Samsung Galaxy A20 (SM-A205) uses a different internal architecture than the Galaxy A20s (SM-A207), so the parts are not interchangeable.

Does the flex solve slow charging issues on the Galaxy A20s?
If the problem is caused by damaged internal traces on the interconnection cable, the replacement solves the anomaly; however, always check the state of the sub-board and the USB port before concluding the diagnosis.
