I have Samsung A21. USB C port didn't want to charge most of the time. I replaced this port and it looks it is working but I got different problems instead.
I reinstalled sim card. There are no updates needed.
Any ideas?

I believe either the daughter board is bad or the installation wasn't done well.
on the daughter board you will find the charging port, the audio jack, a microphone and a antenna connection.
The way it sound it would be either a bad installation where the antenna wasn't reconnected and the microphone placement isn't flush where it needs to be. Or the new board itself is the issue.

Today I opened my phone again. I reinstalled antenna, flex cable and usb board. Everything looks the same. The only issue I see is the antenna cable which looks bad at spots where it bends. Maybe wire is broken inside plastic. I ordered new usb board and antenna. If this won't help I have to buy new phone...
I tested my phone a little more.
1. When I'm in my basement I can't call anybody. Error "phone isn't registered with network". I have no internet.
2. When I'm upstairs or outside I can call and I have internet but usually after restart or turning on/off airplane mode.
3. All people says my voice is broken or they hear only parts of what I say.
4. The best voice is on speaker mode.
5. When I open youtube, all videos are gray, it takes upto 3min to load miniatures and descriptions. When I open any movie it plays for a while and then it stop to buffer for long times...
Same thing happens with websites.
6. Wifi works normal.
