Overview
What this part is
The Galaxy Note 20 has its side (power) key and volume keys on the right side of the frame. Behind them sits a thin flex cable with small switches. If the flex is damaged by a drop, water or wear, pressing a key does nothing, works only sometimes, or triggers by itself.
This is the internal flex cable only, not the outer keys. If the key is missing or bent, you need the outer buttons instead. Test the buttons with the phone restarted first, as a software freeze can look like a button fault.

Professional installation
How a technician fits this part
- Power the phone off and remove the SIM tray.
- Warm the back cover evenly to soften the adhesive, then lift it off carefully.
- Remove the screws and inner panel, then disconnect the battery before touching any other connector.
- Disconnect the button flex and carefully peel it away from the frame.
- Fit the new flex in the same position, reconnect it and the battery, then test every key.
- Refit the inner parts and screws, then seal the back cover with new adhesive.
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 Note 20?
Yes, if Settings › About phone shows Galaxy Note 20 (model SM-N980F or SM-N981B). It does not fit the Galaxy Note 20 Ultra, Note 10+, S20.
Does it fit the Galaxy Note 20 Ultra?
No. The Note 20 Ultra is a larger phone with different internal parts. Only order this for the standard Galaxy Note 20.
Does this include the outer buttons?
No. It is the internal flex cable with the switches. The outer keys stay in the frame and are reused.
Is it made by Samsung?
No. It is a brand new, OEM-quality power and volume button flex cable made to fit the Samsung Galaxy Note 20, and it is tested before dispatch.
Should I fit it myself?
We recommend professional installation. The back cover is glued in place and needs gentle heat, and the thin flex is glued to the frame and easy to tear.
