Whether the mobile phone can be used after it is bent depends on the degree of bending of the mobile phone. In actual repairs, I have encountered many mobile phones that were bent and still used normally.

After the mobile phone is bent, if the bending degree is not serious and it can still be used, it does not need to be repaired, but most people will choose to repair it. If it is repaired, it must be determined which mobile phone it is. The part is bent.

If the back cover of the mobile phone is bent, if the back cover is strong enough, you only need to remove the back cover, place it on the heating platform to heat, straighten the back cover with your hands, and then install it on the phone. If it is not strong, you will need to replace it with a new back cover.

If the middle frame is bent, then the screen will definitely be bent, because the screen and the middle frame are glued together, and repairs require replacing the screen and middle frame.

If the entire phone is bent, including the screen, middle frame, back cover and even the motherboard inside, then if it can be used, don't touch it. If the motherboard is bent, there is no way to repair it. If you need to change the motherboard, screen, middle frame, or back cover, you might as well just get a new phone.
