Owners of Xiaomi Redmi Note smartphones often face the need to replace various elements, which are commonly called βcurtainsβ, which can be confusing, since it covers completely different nodes of the device: from the protective grid of the conversational speaker to the physical plug of the slot SIM-Depending on the specific model, whether itβs Xiaomi Redmi Note 8, Xiaomi Redmi Note 9 Pro or newer versions, the process of dismantling and installing these parts can be radically different.
You need to immediately determine which component requires your attention so as not to cause accidental damage to the body. If you are talking about a speaker grid, then its replacement is often required after moisture or dust hits, which leads to a quiet sound. SIM-The loss or breakdown of this small plastic element can impair the sealability of the case and dust protection as standard. IP. The software βcurtainβ, or quick settings panel, requires a completely different approach related to the software. MIUI or hyperos.
In this article, we will take a closer look at all aspects of replacing physical and software elements that users call curtains. You will learn what tools you will need to carefully open the case, how to order original parts and avoid common mistakes when repairing yourself. The right approach to maintaining your gadget will prolong its life and maintain its aesthetic appeal.
Identification of the problem: which curtain should be changed
The first step in any repair is to make an accurate diagnosis, and when a user searches for information on how to change the curtain, they may be thinking of one of three main components, most commonly a talking speaker grid at the top of the screen, made of fine metallic or polymeric tissue, and eventually clogged with earwax, dust and skin fat.
The second option is a slot stub. SIM-On modern models like the Xiaomi Redmi Note 10 or Xiaomi Redmi Note 12, this part is often complex in shape and a rubber seal. Losing this curtain leaves the insides of the phone open to moisture. A third, less obvious option for beginners, concerns internal security plumes, sometimes called curtains in service manuals, which cover the connectors of the battery or display.
β οΈ Warning: Improper identification of a part before ordering parts may result in the purchase of an unnecessary component. Carefully inspect the damaged item in good lighting using a magnifier or macro shot of another phone before placing a replacement order.
For software elements, the curtain is the Control Center interface, and if you can't swipe from top to bottom to turn on your Wi-Fi or flashlight, the problem is with the system settings or third-party launchers, not the physical case of the device, so you don't need to disassemble the phone at all, you'll need to have a software setup.
Tools and workplace preparation required
You can't do a good job without the right tools. To replace the physical curtains (grids and plugs), you'll need a minimal but specific set. The main tool will be a set of precision screwdrivers, including the PH000 and PH00 cross bits, because the screws in Xiaomi are very tight and small in size.
Plastic spatulas and a suction cup are also indispensable. Metal tools are best avoided when opening the case, so as not to damage the glass of the back cover or the frame. To work with small mesh speakers often require tweezers with curved ends and glue B-7000 or T-7000 to fix new elements.
The organization of the workspace is critical. Cover the table with soft material, such as microfiber, so that small screws do not scratch or get lost. Good lighting is not just comfort, but a necessity, since the fasteners on the Xiaomi Redmi Note are often hidden under stickers or have a black color that merges with the body.
- π§ A set of screwdrivers with a magnetic sting for reliable grip of screws.
- π± Plastic mediators and suction cup for safe opening of the body.
- π§΄ Clay sealant B-7000 for gluing new grids and frames.
- π§² Magnetic mat or organizer for sorting screws of different sizes.
Replacement of the talking speaker grid (external)
Replacing the speaker's external grid is one of the most common procedures. On many Redmi Note models, this grid is glued directly to the display module frame or pasted into the case. First, you need to carefully warm the phone perimeter on a thermophen or heating pad at about 80-90 degrees to soften the glue that holds the back cover.
After removing the back cover and disabling the battery plume (which is a safety requirement), the main board must be removed. The speaker grid is usually located at the top of the housing. The old grid is carefully tucked in with a thin blade or needle. It is important not to damage the membrane of the speaker itself, which is immediately below the grid.
Sequence of action:
1. Remove the back cover.
2 Unscrew the board protection screws.
3. Disable the battery plume.
4. to withdraw the fee (to access the bottom of the grid).
5. Clean out the glue residue and the old mesh.
Stick the new mesh with B-7000 glue.The new mesh needs to be degreased with alcohol and a thin layer of glue around the perimeter. When installing, it is important not to overdo it with the amount of glue so that it does not leak into the speaker hole and worsen the sound. Once installed, let the glue dry for 1-2 hours before assembling the phone.

Use medical alcohol and a cotton swab to thoroughly clean the mesh landing site, and even microscopic residues of old glue can create a gap through which dust will enter the speaker.
Replacement of the plug SIM-card-tray
Stubblock SIM-The card, or end curtain, keeps the hole in the case tight. On modern Xiaomi smartphones, it is often part of the tray or a separate rubber valve. If you lose this part, you can order the original part using the exact model code, for example, for the Xiaomi Redmi Note. 9S Xiaomi Redmi Note 11 Pro.
The replacement process is simple if the plug is removable, but on some models, the rubber seal is glued inside the body, which requires partial disassembly: removing the back cover and unscrewing the screws that fix the frame around the hole. SIM-Carefully remove the remnants of old rubber, trying not to damage the antenna contacts, which often pass in the immediate vicinity.
| Model phone | Type of stub | Presence of sealer | Difficulty replacing |
|---|---|---|---|
| Redmi Note 8 / 8 Pro | Separate tray | Built into the tray. | Low. |
| Redmi Note 9 / 9S | Combined slot | Rubber valve in the shell | Medium |
| Redmi Note 10 / 11 | Separate tray | Built into the tray. | Low. |
| Redmi Note 12 / 13 | Combined slot | It takes glue. | Tall. |
When installing a new plug, make sure it sits tightly and does not protrude outside the body. If the plug has a rubber seal, check its elasticity. The dried rubber will crack quickly, and the moisture protection will have to be changed again in a short time. Some models may require a drop of special electronics glue to fix.
β οΈ Note: Use of non-original plugs SIM-The cards can disrupt communication antennas, and cheap analogues are often inaccurate in size, which creates a backlash and impairs contact with pinguns inside the phone.
Internal curtains and plumes
Inside the Xiaomi Redmi Note, there are also internal security elements that service engineers sometimes call curtains: plastic or metal pads that cover the connectors of the display, battery and touchscreen on the motherboard, their main function is to prevent plumes from moving away during impacts and protect against static electricity.
If you've changed a screen or battery, it's critical to put these safety bars in place. They're fixed by screws that are often of different lengths. If you mess up the screws, you can damage the circuit board or break through the insulation. On Xiaomi Redmi Note 10 Pros and later, these elements are often made as a solid metal frame with plastic inserts.
Why can't we ignore the inside curtains?
When installing internal curtains, make sure that all the plumes are stacked smoothly and not clamped. Often these plastic linings are glued to a special thermally conductive tape or graphite pad to remove heat. If the old pad is damaged, it is recommended to replace it with a new one so as not to disturb thermoregulation of the device.
- π Carefully examine the screws: they can vary in length even within the same plate.
- π§© Check the integrity of plastic latches on the internal curtains before installation.
- π‘οΈ Make sure the heat conductive gaskets are not crumpled and fit tightly to the heat sources.
Software curtain: setting up the MIUI notification panel
If your question was not about physical repairs, but how to change the look or function of the notification curtain, it's about the shell. MIUI and HyperOS have two styles of control panel: the old (Android-style) and the new (iOS-style), switching between them allows you to change the appearance and logic of fast settings.
To change style, go to the Settings menu, then select Control Center, where you can switch to Classic or New Style, and the new style separates notifications and switches, making the interface more modern but less familiar to users of older versions of Android.
There are also third-party apps from the Google Play store that allow you to customize the curtain completely, such as changing transparency, adding widgets, changing the animation of the appearance, but installing such programs requires broad permissions, which can affect the autonomy of the device.

Frequent errors and precautions
Xiaomiβs self-repairing smartphones comes with risks. One of the most common mistakes is using aggressive solvents instead of alcohol when cleaning the case. Acetone or Kalosha gasoline can melt the plastic frame or damage the oleophobic screen cover if liquid leaks under the glass.
Another mistake is ignoring battery shutdown before starting work on internal components, and even short-term closure of the display connector with the battery connected can disable the power controller on the motherboard, leading to costly repairs.
β οΈ Warning: Never try to break the plug. SIM-A card or a grid with sharp metal objects without first heating or softening the glue, which is almost guaranteed to cause chips on the frame or cracks on the body.
When assembling the phone, don't twist the screws "to the point" with excessive force. The plastic used in the Xiaomi Redmi Note is fragile enough. A crack in the screw's seat will make it impossible to further fix the case, and the phone will creak or disassemble on its own.

The main rule of repair: seven times to measure (check model and compatibility), once to cut (glue or screw), haste when replacing small parts often leads to damage of more expensive components.
