Product Description
This signal flex cable is a replacement for the Samsung Galaxy S26 Ultra (SM-S948B). Connecting the antenna module to the motherboard, it is what you look at when the Galaxy S26 Ultra has lost mobile network and Wi-Fi reception because the antenna connection has failed.
The usual causes are a drop or an earlier repair that moved the internal cabling. Reaching the flex means opening the Galaxy S26 Ultra. Note the old cable route on the Galaxy S26 Ultra before removing it, and test reception before sealing the phone.
Key Features & Highlights
Compatibility
- Samsung Galaxy S26 Ultra (SM-S948B)
Signs Your Flex Cable Needs Replacing
- A function linked to the flex (such as display signal, charging, buttons, signal or sensors) stops working or cuts in and out.
- The fault appears after a drop, liquid exposure or a previous repair.
- The flex is visibly torn, creased or has a damaged connector.
- The problem changes when the phone is pressed or flexed.
- Before replacing, reseat the connectors — a loose connector can cause the same symptoms.
How to Check Your Model Number
On the phone or tablet go to Settings › About phone (or About tablet). The model number starts with SM- (for example SM-A145R). It is also printed on the box the phone came in.
