Easy Samsung A21 Screen Replacement
In this article, I explain in a simple, easy, and uncomplicated way, how to replace the damaged screen of your mobile in just 4 steps. But first, to start, make sure you understand how your smartphone is put together.
The first thing you have to do is place the phone with the LCD facing down. You must open the back cover, the battery, and you will see some screws, remove them.
The second step is to disconnect the screen Flex. Do it carefully as it can break. To identify it you will see that it is a small connector. With a small flat screwdriver, apply a little force and it disconnects by itself.
The third step would be to replace what was broken, for this we will need to use two accessories:
- Heat: for this you can use a hairdryer, which should not exceed 120°C. Apply it around the edges
- A plastic pick: exert pressure between the module and the casing.
- Finally, place the new screen (first clean the impurities) and connect the Flex in the same way as it was. Now all that remains is to place the screws and the back cover.
How much does the screen cost?
The price we mentioned at the beginning (28.25€), will only increase by the cost of shipping. Taxes are already included in the purchase. You can choose super fast shipping, or regular shipping which will have its delays. In both options, you can be sure that what you purchased will arrive in optimal condition.
What colors does the screen come in?
For your Samsung color, the module model you need only has black edges, because it is a piece that covers the entire surface of the mobile. Thus, you do not have to be looking among so many colors.
Do I have to go to the original service center?
Undoubtedly, when the screen broke, you thought about this. We are so anxious at this moment because we already know the truth, we will have to go to an original Samsung service center and it will cost twice as much and it is not worth paying so much. But don't worry, we offer you the possibility of doing it yourself and spending half of your money.
Can I replace this Samsung Galaxy A21 screen myself?
Of course, you can! We have already mentioned the steps that should be done quickly and efficiently so that your smartphone works again. At this moment, we will reveal how to understand if the screen of your mobile is broken.
If you follow the steps you will not have problems. You will be able to solve the issue without going to an official service center and in simple steps.
Some recommendations from Samsung A21
First of all, what you should do, put a tempered glass that adheres to the module, and protects it from scratches or marks. The thickness of it usually ranges between 0.3 to 0.5 mm and act as a shield against any blow from a m.. The qualities vary, also their price, but it is still extremely low. And you can place them yourself easily every time it has a mark or is completely broken. This way only the protector will break and the module of your Samsung will remain intact.
Also, we suggest putting on a silicone case that reduces the impact of the fall preventing breakages. And it protects the edges. One of the most used cases are those that have an edge that is a few millimeters above the module, so that when it falls to the floor it does not touch.
Another recommendation, and that everyone is using, is the case that simulates a sling. Not only will we carry our smartphone in a unique way, but also, we prevent it from falling.
How to diagnose if I need to change the screen
Before concluding that it has stopped working altogether, we need to understand if it is the glass or the touch that is broken.
If the touch starts to fail we will notice by seeing the exterior broken and yet, the screen continues to work normally. But the LCD will be broken if the smartphone stops working, that is, if only half is visible, vertical lines appear or everything is dark. To finish confirming that we need to replace it, go to settings. Then, to "About the phone" and tap 7 times on "build number". This will give you access to the "developer options".
Inside this section, select "pointer location", and draw lines across the entire screen. If these are not represented, it means that it is broken and you need to replace it.
