Product Description
This is a replacement LCD flex cable for the Samsung Galaxy S21 5G (SM-G991), used to resolve display connection issues such as no display, flickering, lines on screen, or an intermittent screen response caused by a damaged flex.
Because these symptoms on an S21 5G can also be caused by the screen itself or a loose connector, check those first before fitting a replacement flex cable. Back up the phone and disconnect the battery before unplugging any flex, and reseat the existing display connectors before you decide the flex cable itself needs replacing.
Key Features & Highlights
Compatibility
- Samsung Galaxy S21 5G (SM-G991)
- Check your model before ordering: LCD flex cables differ between models and versions that look alike.
- Model number: Settings › About phone
Signs Your LCD Flex Cable Needs Replacing
- The screen stays black while the phone still rings, vibrates or connects to a computer.
- The display flickers, shows lines or goes blank when the phone is pressed, twisted or dropped.
- The picture only returns when pressure is applied near the display connector.
- A new screen was fitted but shows no image, and the old screen behaves the same way.
- Before replacing, disconnect the battery and reseat the display 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.
Specifications
- Professional fitting is recommended; LCD flex cables are thin and the connectors are easily damaged.
- LCD flex cables are model-specific — check that your device matches the model shown above before ordering.
- Disconnect the battery first, and test the display before any final installation or applying adhesive.
- Before replacing, reseat the existing display connectors — a loose connector can cause the same symptoms.
- If you are unsure which part you need, contact us with your model number before ordering.
