Damage Assessment and Advice on Replacement

Hi,

The only way to really tell is to dis-assemble the phone and assess what physical damage has occurred to the internal components.

Post some images of the damage back here. Here’s how to do this. Agregar imágenes a una pregunta existente

If it appears to be reasonably OK then as a DIY repair all you can do is to temporarily replace the LCD screen assembly and then check the operation of the phone to see what else if anything is wrong and re-evaluate whether it is economically viable to continue the repair.

Until you can “see” what is happening it would only be guesswork.

Here’s a link to the ifixit Xiaomi Mi Mix 2s Screen (LCD+Touch) Replacement guide which may be of some help.

Alternatively if this seems too daunting contact a reputable, professional mobile phone repair service and ask for a quote to repair the phone and then depending on the answer decide if it is worth it. This will cost you but in the end it may be the cheaper and quicker option.
