The Xiaomi Redmi Note 8 is a 2019 smartphone that delivers a lot of value for its price. It has a 6.3-inch LCD screen with a full HD resolution and a notch. The screen is bright and colorful, and it supports HDR10 for better contrast. The screen is also protected by Gorilla Glass 5, which makes it more resistant to scratches and cracks.
The phone is powered by the Snapdragon 665 processor, which is a mid-range chip that can handle most tasks smoothly. It has up to 4GB of RAM and up to 128GB of storage, which can be further expanded with a microSD card. The phone has four cameras on the back: a 48MP main camera, an 8MP wide-angle camera, a 2MP macro camera, and a 2MP depth camera. The main camera can take sharp and detailed photos in good lighting, and it can also record 4K videos. The other cameras can take decent shots of landscapes, close-ups, and portraits. The phone also has a 13MP selfie camera on the front, which can take nice selfies and support face unlock.
The phone has a big 4000mAh battery, which can last for a whole day on moderate use. The phone also supports fast charging with an 18W charger, which can charge the phone from zero to 50% in about half an hour. The phone has some other features, such as a fingerprint scanner on the back, an infrared port, a USB-C port, and a headphone jack. The phone runs on Android 9 Pie with MIUI 10, which is Xiaomi's own software. MIUI 10 has some extra features, such as gesture navigation, dark mode, and app lock, but it also has some ads and bloatware that can be annoying. The Xiaomi Redmi Note 8 is a great choice for people who want a quality smartphone with a big screen, a good camera, and a long-lasting battery. However, it also has some drawbacks, such as the low speaker quality, the lack of NFC, and the bloatware in MIUI.

3. Display issues: Lines, discoloration, or black spots on the screen.
4. Water damage: A screen damaged by water or moisture.
🛠️Tools and materials needed
Before starting the screen replacement process, gather the following tools and materials:
1. Replacement screen: Purchase a high-quality Redmi Note 8 screen replacement.
2. Small Phillips screwdriver: For removing screws.
3. Plastic opening tools: To pry open the phone safely without scratching the casing.
4. Tweezers: Useful for handling small screws and connectors.
5. Adhesive: Double-sided adhesive tape or adhesive glue to secure the new screen.
6. Heat gun or hairdryer: Used to soften the adhesive holding the screen in place.
7. Cleaning cloth: To clean the internal components and remove any debris or dust.
Note: It is recommended to wear safety glasses and use an anti-static wrist strap before starting the process to prevent damage from static electricity.
Stage 1: Preparation
1. Power off the phone and remove the SIM card tray.
2. Heat the front of the phone using a heat gun or hairdryer for a few minutes. This will soften the adhesive holding the screen in place.
3. Insert a plastic opening tool between the frame and the screen to create a gap. Slowly pry open the screen, working along the edges. Be careful not to damage the cables or components inside.
Stage 2: Disconnecting the old screen
4. Once the gap is wide enough, insert plastic opening tools around the edges of the screen. This will prevent the adhesive from resealing while you work on the other sides.
5. Carefully lift the old screen, keeping it at a slight angle to avoid damaging the cables.
6. Locate and disconnect the flex cables that connect the screen to the phone's mainboard. Use tweezers or a plastic opening tool to carefully disconnect them.
Stage 3: Removing the old screen
7. Remove any screws securing the metal bracket covering the LCD flex cable connectors, if present.
8. Gently lift the metal bracket to uncover the connectors and disconnect any additional cables or connectors between the screen and the phone.
9. Now, the old screen should be free from the phone. Set it aside for disposal.
Stage 4: Installing the new screen
10. Before installing the new screen, clean the internal components and remove any debris or dust using a cleaning cloth.
11. Take the new screen and attach any additional cables or connectors to match the connections on the phone, exactly as they were in the old screen.
12. Place the metal bracket back over the connectors and secure it with any screws that were previously removed.
13. Align the new screen with the phone, making sure all the edges are aligned.
14. Slowly lower the screen into place, pressing firmly to ensure proper adhesive contact.
Stage 5: Finalizing the installation
15. Apply heat to the phone's outer edges using a heat gun or hairdryer. This will activate the adhesive and help secure the screen in place.
16. Press down on the screen firmly to ensure a tight seal with the adhesive.
17. Replace the SIM card tray and power on the phone to test the new screen. Check for any display, touch responsiveness, or other issues.
- If the screen doesn't turn on after replacement, ensure that all cables are properly connected.
- If the touch response is inaccurate or unresponsive, check the connections and reseat the cables firmly.
- If the screen is discolored or has lines, it may indicate a faulty screen or cable connection. Recheck the connections and consider replacing the screen again.
- Power off the phone completely before starting the process.
- Wear safety glasses and use an anti-static wrist strap to prevent damage from static electricity.
- Be careful with prying tools to avoid damaging cables or other internal components.
- Use a heat gun or hairdryer cautiously, avoiding direct contact with the screen to prevent overheating.
Redmi Note 8 specific considerations:
