Hey guys! Are you looking to check the screen on your Samsung J5 2016? Maybe you're buying a used one, or perhaps you just want to make sure your current screen is still in tip-top shape. Whatever the reason, I've got you covered! This guide will walk you through several ways to check the screen on your Samsung J5 2016, so you can be confident in its quality. We'll cover everything from basic visual inspections to using diagnostic codes and third-party apps. Let's dive in!

Why Check Your Samsung J5 2016 Screen?

Before we get into how to check the screen, let's quickly discuss why it's important. Here's a few key reasons:

• Buying Used: If you're buying a used Samsung J5 2016, checking the screen is crucial. You want to make sure you're not buying a phone with a cracked screen, dead pixels, or screen burn-in. These issues can significantly impact the phone's usability and your overall experience.
• Identifying Issues Early: Sometimes screen problems develop gradually. By regularly checking your screen, you can identify issues like dead pixels or color distortion early on. This gives you a chance to address the problem before it gets worse.
• Peace of Mind: Knowing your screen is in good condition gives you peace of mind. You can use your phone without worrying about hidden defects or potential problems.
• Resale Value: If you ever plan to sell your Samsung J5 2016, having a screen in good condition will increase its resale value. Buyers are more willing to pay a higher price for a phone with a flawless screen.

Method 1: Basic Visual Inspection

The simplest way to check your Samsung J5 2016 screen is through a visual inspection. This doesn't require any special tools or technical knowledge. Just your eyes! Here’s what to look for:

• Cracks and Scratches: Examine the screen under good lighting. Look for any visible cracks or scratches. Even small hairline cracks can worsen over time, so it's important to identify them.
• Dead Pixels: Dead pixels are small black or colored dots that don't change color with the rest of the screen. To check for dead pixels, display a solid white, black, red, green, and blue image on the screen. You can do this by opening a full-screen image or using a color test app (more on that later). Look closely for any pixels that don't match the color of the rest of the screen.
• Screen Burn-In: Screen burn-in (also known as ghosting) occurs when a static image is displayed on the screen for an extended period, leaving a faint imprint. To check for burn-in, display a gray image on the screen. Look for any faint outlines of icons, keyboards, or other static elements. Screen burn-in can be particularly noticeable on AMOLED screens like the one on the J5 2016.
• Color Distortion: Check if the colors on the screen appear accurate and consistent. Display a photo with vibrant colors and look for any areas where the colors seem washed out, faded, or distorted. Color distortion can indicate a problem with the screen's display calibration.
• Uneven Backlight: If the screen appears brighter in some areas than others, it could indicate an uneven backlight. Display a solid white image and look for any dark or bright spots. Uneven backlight can be distracting and affect the viewing experience.

Tips for Visual Inspection:

• Clean the screen before inspecting it. Dust and fingerprints can make it difficult to see small defects.
• Use a bright, natural light source. Avoid inspecting the screen in dim lighting, as this can make it harder to see subtle issues.
• View the screen from different angles. This can help you spot cracks or scratches that might not be visible from a straight-on view.

Method 2: Using Diagnostic Codes

Samsung phones have hidden diagnostic menus that allow you to test various hardware components, including the screen. Here's how to access the diagnostic menu and run a screen test on your Samsung J5 2016:

1. Open the Phone App: Launch the Phone app on your Samsung J5 2016.
2. Enter the Diagnostic Code: Dial *#0*#. This code will open the diagnostic menu (also known as the secret menu).
3. Navigate the Menu: In the diagnostic menu, you'll see a variety of options for testing different phone components. Look for options like "Red," "Green," "Blue," or "LCD Test." These options will display solid colors on the screen, allowing you to check for dead pixels and color accuracy.
4. Perform the Screen Test: Tap on each color option (Red, Green, Blue) to display a full-screen image of that color. Carefully examine the screen for any dead pixels, discoloration, or other anomalies.
5. Exit the Menu: Once you've completed the screen test, you can exit the diagnostic menu by pressing the back button or the home button.

Important Notes about Diagnostic Codes:

• Diagnostic codes can vary depending on the phone model and software version. If *#0*# doesn't work on your Samsung J5 2016, try searching online for other diagnostic codes specific to your phone model.
• Be careful when exploring the diagnostic menu. Some options can change phone settings or perform actions that you might not understand. It's best to stick to the screen test options and avoid making any other changes.

Method 3: Using Third-Party Apps

Several third-party apps available on the Google Play Store can help you test your Samsung J5 2016 screen. These apps often provide more comprehensive testing options than the built-in diagnostic menu. Here are a couple of popular apps you can try:

• Dead Pixel Detect and Fix: This app is designed to detect and attempt to fix dead pixels on your screen. It displays a series of solid colors and patterns to help you identify dead pixels. While it claims to fix dead pixels, the success rate can vary, and it's often more effective at detecting them.
• Screen Test: This app offers a variety of screen tests, including color tests, gradient tests, and multi-touch tests. It allows you to thoroughly evaluate the screen's performance and identify any potential issues. The screen test includes tests for color accuracy, brightness, contrast, and touch sensitivity.

How to Use Third-Party Apps:

1. Download and Install: Go to the Google Play Store and search for "Dead Pixel Detect and Fix" or "Screen Test." Download and install the app of your choice.
2. Run the Tests: Launch the app and follow the on-screen instructions to run the screen tests. The app will typically display a series of colors, patterns, or interactive elements that you can use to evaluate the screen's performance.
3. Analyze the Results: Carefully observe the screen during the tests and look for any anomalies, such as dead pixels, color distortion, or touch sensitivity issues. The app may provide feedback or suggestions based on the test results.

Method 4: Checking Touchscreen Sensitivity

It's also important to check the touchscreen sensitivity of your Samsung J5 2016. A faulty touchscreen can make it difficult to use your phone, even if the display itself is in good condition. Here's how to check the touchscreen sensitivity:

• Using the Dial Pad: Open the Phone app and go to the dial pad. Try typing numbers and symbols across the entire screen. Make sure that each key responds accurately and consistently. If you notice any areas where the touchscreen is unresponsive or inaccurate, it could indicate a problem.
• Drawing Test: Open a drawing app (like Samsung Notes or a third-party drawing app). Use your finger or a stylus to draw lines and shapes across the entire screen. Pay attention to how smoothly the lines are drawn and whether there are any gaps or breaks. Inconsistent or broken lines can indicate a problem with the touchscreen sensitivity.
• Multi-Touch Test: Use a multi-touch testing app (many of the screen testing apps mentioned earlier include this feature). These apps allow you to test the touchscreen's ability to recognize multiple touch points simultaneously. Place multiple fingers on the screen and move them around. Make sure that the app accurately tracks all touch points without any lag or errors.

Troubleshooting Touchscreen Issues:

• Clean the Screen: A dirty or oily screen can interfere with touchscreen sensitivity. Clean the screen with a soft, lint-free cloth.
• Remove Screen Protector: A damaged or poorly installed screen protector can also affect touchscreen sensitivity. Try removing the screen protector to see if it improves the touchscreen performance.
• Restart Your Phone: Sometimes a simple restart can resolve temporary touchscreen issues.
