If your phone still rings and vibrates but the screen is pitch black, the internal AMOLED panel is shattered. Even if the outer glass is perfectly intact, the inner display is dead. Software resets won't fix this; it requires a physical screen replacement.
It is a heart-sinking moment: your smartphone slips out of your hand and hits the concrete. You pick it up, wipe it off, and the Gorilla Glass doesn't have a single scratch. Yet, the screen won't turn on. You can hear notifications coming in, and the morning alarm still goes off. This is the most common failure point for AMOLED displays used in the Samsung Galaxy A-series.
Why Is the Glass Fine but the Screen Dead?
An AMOLED display is basically a sandwich. The top layer is a thick, impact-resistant protective glass. Right beneath it is the actual display matrix, which is as thin and fragile as a sheet of aluminum foil. When the phone drops, the outer glass flexes and survives, but the kinetic energy transfers directly into the ultra-thin matrix, cracking it instantly.
Sometimes, the death isn't instant. You might notice a small purple or green ink-like spot that slowly bleeds across the entire screen over a few hours. Once it goes completely black, the panel is permanently ruined.
Method 1: The Force Restart (Ruling out a glitch)
Before concluding that the hardware is destroyed, make sure the operating system didn't just freeze from the impact.
- Press and hold both the Volume Down button and the Power button at the same time.
- Keep holding them for about 10 to 15 seconds.
- You should feel a short vibration indicating the phone is rebooting.
- If you see the Samsung logo, you're in luck! If you hear the startup chime but the screen remains black, the hardware is dead.
Method 2: How to Recover Your Data
If the touch screen is dead, you can't simply plug the phone into a PC—Android security requires you to tap "Allow access to data" on the screen, which you can't see.
- Get a USB Type-C to USB-A OTG (On-The-Go) adapter.
- Plug a standard computer mouse into the phone.
- Even if the screen is black, you can try to "blindly" click and drag upwards to unlock the phone, entering your PIN using the mouse clicks (if you remember the layout).
- Once unlocked, if the phone is connected to Wi-Fi, it will automatically start syncing your photos and contacts to your Google Drive or Samsung Cloud.
An original Samsung A51 screen replacement can cost anywhere from $100 to $150 at a certified repair shop (like uBreakiFix). Given that used A51s sell for about the same price today, it is often more economical to recover your data, sell the broken phone for parts, and upgrade to a newer model.

Yes, but with major trade-offs. Cheap LCD/TFT replacement screens are much thicker, drain the battery faster, and most importantly, the under-display fingerprint scanner will permanently stop working because LCD screens don't allow light to pass through to the sensor.
