Samsung Galaxy A15 4G vs 5G Screen: Which Replacement Do You Need?

The Samsung Galaxy A15 4G and A15 5G use different display assemblies, so ordering the correct one matters — fitting the wrong part is the most common A15 repair mistake. Here's how to identify your exact model and pick the right screen.

How to identify your A15

Direct answer: check Settings > About phone, or the model number on the box or SIM tray. The A15 4G is SM-A155F and the A15 5G is SM-A156B. Order the screen that matches your model number exactly.

Are the 4G and 5G screens interchangeable?

No — while they look similar, the assemblies and connectors differ between SM-A155F and SM-A156B, so you must match your exact model. Some OLED-with-frame assemblies are cross-compatible and list both model numbers; always confirm your model number is included before ordering.

Don't forget the fingerprint sensor

The A15 has an in-display fingerprint sensor. A budget TFT screen won't support it, so if fingerprint unlock matters to you, choose an OLED replacement — full detail in our A15 OLED vs LCD guide. For the overall repair, see A15 screen replacement.
