You pick up your Galaxy one morning and there is a thin green or pink line running from top to bottom of the screen. Or the phone slipped out of your hand in a parking lot at Dadeland, and now the glass is cracked, part of the display is black or the touch responds on its own. Samsung screens are bright and sharp, but the AMOLED panels inside them do not forgive drops, pressure or heat very well. Here is how to tell what kind of screen problem you have, what to do right away and what to expect from a repair in Miami.

This guide covers green lines, black spots, ghost touch and cracked glass on Galaxy phones, how to protect your data, when the problem is actually something else, and how a Samsung screen repair works at WEGOWEFIX in Kendall.

Green line, black spots or cracked glass: what each one means

On a Samsung, the glass you touch and the AMOLED display under it are bonded together into one panel. That is why the symptoms tell us a lot:

• A single vertical green, pink or white line. This is a display panel failure. It can show up after a drop or pressure, like sitting on the phone in a back pocket, and some Galaxy owners have reported it appearing with no drop at all, sometimes after a software update. The line usually stays put or slowly gets worse.
• Black spots or ink-like blotches that spread. The OLED layer is damaged under the glass. These spots tend to grow over days or weeks.
• Cracked glass, but the picture is perfect. The display still works, but the crack lets in moisture and dust and the damage often spreads. On Samsung the glass is not normally replaced on its own, so the fix is the full screen.
• Ghost touch. Apps open by themselves or the keyboard types random letters. This often follows a crack or a hit near the edge.
• Black screen, but the phone rings or vibrates. The phone is alive and the display or its connection failed. If you are an iPhone user with the same problem, see our guide on an iPhone black screen after a drop.

What to do right away

1. Back up your phone while you still can. If the screen still works, back up with Samsung Cloud, your Google account or Smart Switch on a computer. Photos and WhatsApp chats are what people miss most.
2. Restart the phone once. If the line or flicker disappears and never comes back, it may have been a software glitch. If it returns, it is hardware.
3. Check in Safe Mode. If ghost touch stops in Safe Mode, an app may be the cause. If it continues, the screen is the likely problem.
4. Put a cheap screen protector or clear tape over cracked glass so glass splinters do not cut your fingers and the crack does not spread as fast.
5. Keep it out of the sun and the car. Heat on a Miami dashboard is hard on a damaged panel and on the battery.
6. If the screen is black, try an external display. Many Galaxy models can mirror to a TV or monitor with a USB-C to HDMI adapter, which can let you unlock the phone and save your data.

Things that make it worse

• Pressing on the line or the spots to see if they move. Pressure spreads OLED damage.
• Using the phone with exposed glass in the rain or at the pool. A cracked screen is no longer water resistant.
• Ignoring a screen that is lifting. If the display is bulging or separating from the frame, the battery may be swelling underneath it. Stop charging it and bring it in. Our Samsung battery replacement page explains the warning signs.
• Software tricks for hardware damage. A factory reset will not remove a green line caused by a damaged panel, and it can erase data you have not backed up.

Is it under warranty or a Samsung program?

If your Galaxy is new, was never dropped and the green line appeared on its own, it is worth checking your Samsung warranty or carrier insurance first. Samsung has at times offered help for some models with this issue. If the phone was dropped, has a crack or is out of warranty, an independent repair shop is usually the faster and more practical option. We will tell you honestly which route makes more sense for your case.

What a Samsung screen repair looks like

On many Galaxy S, Note and A models the replacement screen comes as a complete assembly, sometimes with the frame already attached. The technician opens the phone, moves over the internal parts and installs the new display, then tests touch, brightness, the front camera, the earpiece, and the fingerprint sensor, which on many models sits under the screen.

A few things to expect afterwards:

• You may need to register your fingerprints again.
• Your apps, photos and settings stay on the phone. We do not need to erase it to replace the screen.
• Curved-edge models like the older Edge and Ultra phones take more care to open and seal, so we check the part availability for your exact model before we start.

What to expect at WEGOWEFIX

• Free diagnosis. We check whether the problem is the panel, the connector, the battery or software, so you only pay for what actually needs fixing.
• The price before the repair. You know the cost and approve it before we touch the phone.
• Same-day repair when parts are in stock. If the screen for your model has to be ordered, we tell you up front.
• Walk-ins welcome. No appointment needed. You can also send a photo of the screen on WhatsApp first so we can confirm the part.
• Board-level work in-house. If the phone took a hard hit and something beyond the screen is damaged, we handle diagnosis and microsoldering in our workshop.
