I want to buy Huawei p20pro with bill on ebay classifieds,

but do not know what to look for and how to buy settled. So I have to unpack it on site and check it? If so, then what exactly, probably the number of the smartphone? Or if it is verschweißr, you should not check anything?

Would be very grateful for any help!

Personal meeting. Check the goods. Do not send money in advance.

My first check would be: Is this a private or a commercial seller?

Oa

Probably the part has fallen from the vice and the bill is fake.

You could also buy such a part at Media Markt and so on. Even if you have to dig deeper into the bag.

Such shops are always dubious and you can weld this part also at home.

Just before Christmas should be the alarm bells.
