- Make sure you have no static electricity. For this, it is good to have an antistatic bracelet and wear shoes that disperse static electricity.
- To separate the module from the smartphone, you need something that generates heat, such as a hairdryer or a heat gun at 120°, never use one that exceeds 120° because otherwise, you will melt the essential chips.
- You have to apply heat to the corners so that the adhesive dissolves. To completely remove the screen you can use a pick, which is part of the necessary toolset for changing.
- Then continue applying heat, but in the center of the phone, do it carefully and quickly so as not to damage the battery (it is ideal to remove it).
- When you finish removing it, be very careful, as you will disconnect the damaged screen from the motherboard. Look very carefully at how the screen is attached, there should be a small chip.
- When removing it, clean the area very well with the soft cloth to remove all the adhesive that remained. You can use liquids that were made for this purpose, but if you could not find these liquids do not use water as it will damage most of the components, just use the soft cloth.
- We are almost finished, now connect the new display to the base module and connect the chip that the smartphone has from the factory.
- Now you just have to put the new Samsung A31 screen.

How to find out if I have a broken screen
Before concluding that it is completely defective, it is important to know if it is the film protector or the touch that is damaged.
If the touch is defective we will notice by seeing the top part shattered but the screen continues to be displayed normally. But the LCD will become unusable if the smartphone stops working, that is, if only a part is visible, vertical lines appear or everything is black. To finish verifying that we must repair it, go to settings. Then, to "About the phone" and tap 7 times on "build number". This gives you access to the "developer options".
Inside this item, select "pointer location", and draw lines all over the screen. If they are not drawn, it means that there are problems and you have to change it.
