A little imagination!
I've been a Samsung smartphone user for years,
After comparing Huawei from the tech here builds better gadgets, I brought 2 Mate series.
The devices are perfect or at least as good as samsung to network connections also internet.
Now my question;
It may be that the Samsung company sees this Huawei competing danger, joins together with network providers, makes sure (by agreement, a container Samsung devices in vain, which in contract renewals passed on to customers) when calling from Huawei devices or go to the Internet, that a delay or constant obstacles occur?
Try to ask your question in German… Man oh man, - without words!
If I could speak German like that, do you ask questions like those of you, if you did not understand the question, do not comment either, could also ask here for Urdisch or English but you are not 100% capable, because I'm 101% sure.
