My A41 wasn't charging, so i replaced the circuit board with the charging port on it.
My mobile internet (4g) has very bad connection. however my wifi and bluetooth work just fine.
Also, people sometimes cannot hear me when i talk on the phone, but after recording my microphone seems to work just fine
Do i just have a crappy board?
Is this a good question?

Hi Jorik,
I would double-check the coax cable that runs down the side of the battery to the charging board. It's possible it either isn't connected completely or suffered damage in the process of replacing the charging board. Check the picture on Step 9 of this guide to replacing the charging board.

Check to be sure the connector isn't bent or broken and that the cable is also intact. Should you find anything wrong with it, it's replaceable by itself.

Good luck; let us know what you find.

So the coax cable is responsible for Wifi, bluetooth and LTE?
@jorikjeeninga From the descriptions I read, it sounds like it. So it would be unusual for only one of those to be failing if it was a cable issue. That may tend to point to the replacement charging board being defective. Can you try swapping the old board back in to check?
unfortunately i discarded the original charging board. I replaced the coax cable and put in a 2nd replacement carging board. The problem persists.
