3 Bluetooth does not work after replacement
This phone has faced various difficulties. First it went into the water, and then shortly after having it repaired it fell on the ground. After this latest incident, I decided to repair it myself. I will preface this by saying that I was not using the phone (it may be that there were already problems but the user was not using bluetooth).
I changed the battery, display and front camera. Now everything works except the bluetooth. It doesn't always connect with devices, at best it connects but works poorly. For example, if I connect headphones, those few times I can connect them, it is jerky and I can't get too far away from the phone. Any recommendations?
I leave attached photos of how I assembled the phone:

One question: is there a possibility to change a bluetooth card or is it built into the motherboard?
Это хороший вопрос?
