I didn't say which phone it was, so take it and keep it.

It's okay, it is estimated that the mobile phone cable is broken, and it can be repaired anywhere, it is best not to go to private maintenance, and be careful that the black-hearted dealer will replace the parts for you. It's more troublesome to go to customer service, they have a lot of things to do every day, and you'll have to wait for a while to fix it, so it's best to find an acquaintance to fix it, rest assured. Minor issues.

The motherboard is broken, and my problem is the same, don't go to customer service, that drink blood.

Falling... If you take it to repair, you may be saved... But it's just maybe, because it depends on whether the motherboard inside is broken

u go to the after-sales service and say that there is something wrong, don't say that you have fallen.

The cable is broken, fix it! That's the case with my classmate's love for him, and it only took him a week
