Samsung Galaxy A31: Charging problems even after changing power (sister board)

Thu, 22 Jul 2021 12:38:09 -0700

The title sums it up, here is what I tried.

I tried replacing the battery of the samsung a31
I tried replacing the charging board
I tried letting it charge for half a day on multiple chargers.

Before this I also replaced the screen, right now it boots but doesn’t charge (only a small part of the charge remains)

I am out of ideas, is the sister board that I ordered faulty?
Is the flat cable faulty (if that is the cable that charges the phone), I attached a photo of it.
Also where can I find datasheets or summaries of what every cable/component does for phones.
I’ll attach detailed pictures of all the components… I really feel out of ideas, what am I missing :( ?

My phone doesn't connect to WiFi network with more than 2 m distance. I have to be in the same room as the WiFi.

Another thing, my phone requires to be in close physical contact with the device whenever I'm connected to a device that uses bluetooth like wireless earphones or speaker.

Samsung Galaxy A31: Problems with calling people

Tue, 13 Dec 2022 11:12:10 -0700

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.

When I'm in the basement I can't call at all. I get error" You are not registered to network".
When I'm upstairs I can call after doing restart but most people don't hear or hear me bad.

I reinstalled sim card. There are no updates needed.

Any ideas?
