Overview
What this part is
Inside the Samsung Galaxy A20 a long flex cable joins the main board at the top to the charging board at the bottom, and a flex also carries the screen connection. These cables are easy to tear or crease when the phone is opened, and they can corrode after liquid damage.
If a new screen or charging board does not work, or the fault started after another repair, a damaged flex is often the cause. Compare your old cables with the photos before fitting.

How a technician fits this part
- Power the phone off and remove the SIM tray.

- Remove the screws and inner cover, then disconnect the battery before anything else.
- Unplug both ends of the old flex cables and lift them out of the frame.
- Lay the new cables along the same path, press every connector on firmly, reconnect the battery and test screen, touch and charging before closing.

Check that the part matches the device before fitting it or removing any adhesive backing. Once a part has been fitted, it cannot be returned for a change of mind. Faulty parts are always covered.
FAQ
Frequently asked questions
Will this fit my Galaxy A20?
Yes, if Settings › About phone shows Galaxy A20 and the model code SM-A205F. It does not fit the Galaxy A20e, Galaxy A20s, Galaxy A30.
Does it fit the Galaxy A20e?
No. The Galaxy A20e is a different model with a different internal layout. Check the model name in Settings › About phone before you order.
Will it fix a black screen?
Only if the flex is the cause. If the screen itself is cracked or dead, you need a new screen. Test with a known-good screen if you can.
Is it made by Samsung?
No. It is a brand new, OEM-quality main board flex and lcd flex cable made to fit the Samsung Galaxy A20, and it is tested before dispatch.
Should I fit it myself?
We recommend professional installation. The Galaxy A20 has to be opened, the battery disconnected, and the connectors are small and easy to damage.
