Samsung Galaxy A15 Black Screen but Phone Still On? Causes & Fix (UK)

If your Samsung Galaxy A15 has a black screen but still rings, vibrates or shows the charging light, the phone is working and the display has usually failed — a fixable fault, with a replacement screen from £26.77. Before buying anything, run the two-minute checks below, because a frozen screen can look identical to a broken one. Here is how to tell them apart.

Free checks to try first

1. Force restart: hold Power + Volume Down for 10–20 seconds. This clears a frozen or crashed display.
2. Charge for 15 minutes: a fully drained battery can mimic a black screen — watch for the charging indicator.
3. Call it from another phone: if it rings or vibrates, the board and battery are fine and the screen is the likely fault.

If the display stays black after all three and the phone still shows signs of life, the screen assembly has failed.

Galaxy A15 black screen: causes and fixes

Direct answer: a black screen that still vibrates after a drop almost always means the display has failed while the rest of the phone works — exactly what a replacement screen resolves.

What does a Galaxy A15 screen replacement cost?

A replacement Galaxy A15 OLED screen with frame starts at £26.77, with original LCD assemblies (4G / 5G) around £44. See the full A15 screen replacement options.

Important: the A15 has an in-display fingerprint sensor, so a budget TFT screen won't support fingerprint unlock — choose an OLED replacement if you need it. More on this in our A15 OLED vs LCD guide.

Frequently asked questions

Why is my Samsung A15 screen black but still on?

The board and battery are working but the display has failed, usually after a drop. A force restart rules out a freeze; if the screen stays black, it needs replacing.

How do I fix a Galaxy A15 black screen?

Try a force restart (Power + Volume Down for 10–20 seconds) and a 15-minute charge. If the phone rings or vibrates but the screen stays dark, replace the display assembly.

How much is a Galaxy A15 screen replacement in the UK?

From £26.77 for an OLED-with-frame assembly, or around £44 for an original LCD. Fitting it yourself is free; a repair shop adds labour.

Will a new screen keep my fingerprint sensor working?

Only if you choose an OLED screen — the A15 uses an in-display sensor that budget TFT panels don't support.
