  20. Xiaomi Redmi Note 7 Screen and Metal case Replacement, Close your phone: 20 단계, 이미지 1/3 Xiaomi Redmi Note 7 Screen and Metal case Replacement, Close your phone: 20 단계, 이미지 2/3 Xiaomi Redmi Note 7 Screen and Metal case Replacement, Close your phone: 20 단계, 이미지 3/3
    • Before trying to close your phone, try to turn it on, to charge it and to check if it works correctly. Like this you can solve any issue without the need of opening it back

    • To close your phone you could use the original adhesive if you were careful enough during removal, though this could lead to later unsealing of the case; hence I suggest you to use a specific glue like the B-7000 glass glue

    • Put either the adhesive or the glue around the perimeter of the phone (not the rear glass) in the most homogeneous way possible

    • After application gently close the rear glass and apply some pressure

    • You should apply even pressure on the whole screen for many hours, you should use the screen clamps to guarantee perfect adhesion

    • If your phone looks like the last picture simply heat it up again and remove all the adhesive with isopropil alchool and start again. otherwile it could open at any moment

    • Don't worry if some glue pops out from the borders, you'll be able to remove it once dried either with your fingernails or isopropil alchool

결론

After the last step you should have correctly closed the rear glass of your device and you can now use it again good as new!
