@ali.loz You should be able to replace, it I didn’t do it on a MX4Pro but some other phones.
If you think you are able to replace it, find a seller you trust at ebay or alliexpress and order it.
Or contact your seller, maybe he has one for you.
You should be able to find a dear down youtube video of this, or just ask a friend of you / local store do perform the screen replacement for you.
@ali.loz your english is good :D so far, no need to be sorry.
Be careful and don’t trust every seller. Double check how long the shop exists and how many customers they had and how happy the customers were.
