Before you start disassembling, you need to have a comfortable workspace with good lighting, you need a clean, flat surface covered with soft material, so that small screws do not get lost and parts do not get scratched, and the lack of dust and static electricity will also play an important role in the safety of the electronics of the device.

To successfully complete the task of removing the lid, you will need a minimum set of tools that can be found at home or purchased at any electronics store, the main tool will be a plastic blade or a mediator that will allow you to tamper with the case without risking damage.

  • πŸ”§ Plastic blade (spooger) or mediator for opening latches.
  • πŸ”§ Thin metal spatula (use with extreme caution).
  • πŸ”§ Suction cup for lifting the cover (optional, but convenient).
  • πŸ”§ Phillips screwdriver for screws under the battery.

The use of metal objects such as knives or needles is not recommended, as they can easily break through the battery or damage the plumes.If there is no professional spooger at hand, it is better to use a plastic card pre-harvested in the corner than risk the integrity of the gadget.

Analysis of the design of the Redmi 4A

The Redmi 4A is made of matte plastic, which, despite its strength, is sensitive to spot impacts and curves. The back is held not only by screws under a plug, but also by a system of internal latches around the perimeter of the device. Understanding where these latches are located is critical to preventing breakage.

Unlike more expensive models, there are no additional screws on the sides, which simplifies the process, but requires accuracy when snapping. Plastic becomes more fragile over time, especially if the phone has often been subjected to temperature changes, so you need to act smoothly and without sharp jerks.

Notice the joints of the body: it's the gap between the main frame and the back cover that you need to insert the tool, and the micro gaps are visible to the naked eye when you look at the sidelight.

Step-by-step: how to remove the back cover

The first step is to extract SIM-This is a mandatory procedure, because the presence of a tray creates stress in the structure and can lead to a breakdown of the mechanism when you try to open the lid.

Then you flip the smartphone down and find a rectangular plug at the bottom of the back, and underneath it, you have two screws that hold the bottom of the lid, and you need to carefully twist them out with a cross screwdriver of the right size and put them away in a safe place.

Now you can start the process of snapping, insert the plastic blade into the gap between the frame and the lid in the lower corner, where the screws were previously, and with a slight push, swipe the tool along the side face, hearing the characteristic clicks of the locks opening.

Move around the perimeter of the device, sequentially releasing the latches. Don't try to bend the lid immediately after opening one corner, it can break the plastic. Walk the tool around the circuit until the panel begins to detach freely.

⚠️ Warning: Do not use force if the lid fails. Check if all screws are twisted and if the tool is stuck somewhere. Excessive effort will lead to white clatters on the plastic.

Work with the battery and internal components

After successfully removing the back cover, the smartphone’s internal device will open to your eyes. In the Xiaomi Redmi 4A, the battery takes up a significant part of the space and is closed with an additional plastic lining, which is also fixed by screws.

To access the plumes and the battery itself, you need to unscrew the screws located under the plastic lining at the bottom of the device (usually 10 pieces, but the number can be cooked).

  • πŸ”‹ Carefully disconnect the battery plume from the motherboard.
  • πŸ”‹ Check the condition of the contact site for oxidation.
  • πŸ”‹ If the battery is swelling, do not press on it with sharp objects.

The adhesive base on which the battery is held loses its properties over time, but in rare cases it can hold firmly. To extract the battery, you can use a suction cup or gently tuck it with a plastic card from the end.

If your goal was to replace the screen, you need to remove the metal frame that covers the display plumes after the battery is turned off, which is usually attached with several screws and plastic latches.

Typical mistakes when disassembling a smartphone

One of the most common mistakes is ignoring the screws under a plug, and many users try to force the lid off, forgetting that the two screws are still holding the structure, which leads to the breaking of the plastic mounting poles.

Another mistake is to use a tool that is too thick, so the blade should not go deeper than 2-3 millimeters into the gap, and a deep dive will ensure that the plumes are cut or the side buttons are damaged.

What to do if the lid is cracked?
If you hear a crunch at the autopsy and see a crack, don't panic. Small chips can be taped with transparent tape from the inside or replaced with a new lid, as they are sold separately and are inexpensive.

It is also common to forget to turn off the battery before working with other components, and touching the contacts under tension with tweezers can short-circuit and disable the motherboard.

Take your time and pull the lid. Plastic is a viscous material, and a sharp jerk can lead to unpredictable results. It is better to spend an extra minute warming up with a hair dryer (if the glue is old) or more thoroughly passing the perimeter with a spatula.

Comparison of opening methods of the body

There are several approaches to removing the back panel, and the choice of method depends on the condition of your device and the tools available. Below is a table comparing the effectiveness and risks of the different methods.

Assembly and performance check

After the necessary repairs (replacing the battery, screen or cleaning the speaker) are done, the assembly phase is as careful as disassembly, and first of all, make sure that all the plumes are tightly seated in their connectors and are fixed with clamping slats.

Put the battery back in place and plug it into the motherboard. Don't put the lid in right away -- first check if the phone is turning on and if the touchscreen is working, and that saves time in case you forget to plug in some connector.

Before final assembly, wipe the inside of the lid and the smartphone frame with an alcohol napkin – this will remove dust and prints that can be seen through the translucent plastic.

Can I use the Redmi 4A without the back cover?
Technically, the phone will work, but it's not recommended, because without the cover, the plume press is broken, dust and moisture get inside, and there's a risk of short circuits or mechanical damage to the components.
Where to buy a new back cover for Xiaomi Redmi 4A?
Original and compatible lids can be found at sites like AliExpress, local phone parts stores, or service centers, and the price is usually low, making it cost-effective to replace them.
What to do if the latch on the cover is broken?
If one latch breaks, the phone is likely to hold onto the rest of the latch, and if the plastic itself cracks around the latch, you can carefully glue the chipping site with superglue (with caution!) or just put up with a little backlash using a case.
