After the phone is bent, if the bending degree is not serious, you can continue to use it or not, but most people will choose to repair it. If it is repaired, it depends on which part of the phone is bent.
If the back cover of the mobile phone is curved, if the back cover is strong enough, you only need to remove the back cover and put it on the heating table to heat it, then break it straight by hand and install it on the mobile phone. If it is not strong, it needs to be replaced with a new back cover.
If the middle frame is bent, the screen will certainly be bent, because the screen and the middle frame are glued together, so it is necessary to replace the screen and the middle frame for maintenance.
If the whole mobile phone is bent, if the screen, middle frame, back cover and motherboard inside are bent, if it can be used, don't touch it. There is no way to repair a bent motherboard. Change the motherboard, screen, middle frame and back cover, it is better to change a new mobile phone directly.
