Huawei P20 display color leaked?

I have or had since May a Huawei P20 but I got down 2 months ago while cigarettes down (not on the display) are still cracks in the display and you see the display three times so you can see nothing more and it looks as if black color leak would anyone have any idea what could be broken and how much the repair could cost?

Whatever happened there - you can't fix such a display, because you have to (unfortunately) replace the whole module. Costs about 130 euro upwards (according to https://www.handyreparaturvergleich.de/huawei-smartphones-reparatur/defektes-huawei-p20-display-diagnose-reparieren-preisvergleich.html#display). Can you do it yourself, but only if you know it.

Hope I could help.

Thank you! I would have a question but still: do I have to go there to a certain load or does that the Telekom also whereby I can imagine that it would be more expensive with the Telekom

There are many stores that fix this, probably the cheapest. But maybe there's still a guarantee? (Rather unlikely if you've thrown it down yourself ;-) As far as I know, the telecom also makes cell phone repairs, but you're probably right and it's more expensive.

Here you can check for warranty:
